Earth (or the Earth) is the third planet from the Sun and the densest and
fifth-largest of the eight planets in the Solar System. It is also the largest
of the Solar System's four terrestrial planets. It is sometimes referred to
as the World, the Blue Planet, or by its Latin name, Terra.]
Home to millions of species including humans, Earth is currently the only
astronomical body where life is known to exist. The planet formed 4.54
billion years ago, and life appeared on its surface within a billion years.
Earth's biosphere has significantly altered the atmosphere and other
abiotic conditions on the planet, enabling the proliferation of aerobic
organisms as well as the formation of the ozone layer which, together
with Earth's magnetic field, blocks harmful solar radiation, permitting life
on land. The physical properties of the Earth, as well as its geological
history and orbit, have allowed life to persist during this period. The
planet is expected to continue supporting life for at least another 500
million years.](https://image.slidesharecdn.com/2-110331044143-phpapp02/85/2-1-320.jpg)

Chapter 2 Earth As Planet
Chapter 2 Earth As Planetbrhector21The document discusses the phases of the moon. It explains that the moon does not produce its own light, but rather reflects light from the sun. As the moon orbits Earth, different portions are illuminated by the sun, appearing to change shape from our perspective on Earth. This cycle, where the illuminated portion appears to grow and then shrink over the course of around 29.5 days, is what causes the phases of the moon. The document then defines and provides images for each of the 8 main phases: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent.

History and formation of the Earth (Presentation #2 Bilogy L2 project)
History and formation of the Earth (Presentation #2 Bilogy L2 project)Sebasttian98The Earth formed 4.54 billion years ago from a solar nebula. Its early atmosphere was toxic and volcanic activity and asteroid impacts were common. One large impact is believed to have formed the Moon. Over billions of years the planet cooled and developed tectonic plates and a stable crust allowing liquid water and the first life. The atmosphere gradually gained oxygen as photosynthetic life evolved. Multicellular life diversified in the Phanerozoic Eon starting over 500 million years ago, though many species died out in extinction events like the one that ended the Cretaceous Period.

Solution
Earth, also known as the world, Terra, or Gaia, is the third planet from the Sun, the densest planet in the Solar System, the largest of the Solar System\'s four terrestrial planets, and the only celestial body known to accommodate life. It is home to about 8.74 million species. There are over 7.2 billion humans who depend upon its biosphere and minerals. The Earth\'s human population is divided among about two hundred independent states that interact through diplomacy, conflict, travel, trade, and media. According to evidence from sources such as radiometric dating, Earth was formed around four and a half billion years ago. Within its first billion years, life appeared in its oceans and began to affect its atmosphere and surface, promoting the proliferation of aerobic as well as anaerobic organisms and causing the formation of the atmosphere\'s ozone layer. This layer and Earth\'s magnetic field block the most life-threatening parts of the Sun\'s radiation, so life was able to flourish on land as well as in water. Since then, Earth\'s position in the Solar System, its physical properties and its geological history have allowed life to persist

The Earth
The Earthvaibhav632616The Earth has undergone constant change over its 4.54 billion year history, with life evolving in response. There have been at least 8 mass extinction events that have significantly impacted life on the planet. Life continues to spread and adapt wherever viable conditions allow. The four spheres that make up the structure of the Earth are the biosphere, hydrosphere, lithosphere, and atmosphere. The layers of the atmosphere include the troposphere, stratosphere, mesosphere, and thermosphere. Steps that can be taken to help save the Earth include conserving water and the environment, celebrating Earth Day, planting trees, and following a reduce, reuse, recycle mantra.

It describes how Earth formed around 4.54 billion years ago from a solar nebula, and over time developed a solid crust and liquid water on its surface. Early life first appeared between 3.5 to 4 billion years ago in the form of microbes like bacteria and stromatolites. The first complex multicellular organisms emerged around 580 million years ago in an event known as the Cambrian explosion, marking the rise of most major phyla. Life has continued to evolve on Earth, with species adapting and going extinct over geological eras as environments changed.

Earth
EarthLilit SahakyanThe Moon is a relatively large, terrestrial, planet-like natural satellite, with a diameter about one-quarter of Earth's. It is the largest moon in the Solar System relative to the size of its planet, although Charon is larger relative to the dwarf planet Pluto. The natural satellites of other planets are also referred to as "moons", after Earth's.
The gravitational attraction between Earth and the Moon causes tides on Earth. The same effect on the Moon has led to its tidal locking: its rotation period is the same as the time it takes to orbit Earth. As a result, it always presents the same face to the planet. As the Moon orbits Earth, different parts of its face are illuminated by the Sun, leading to the lunar phases; the dark part of the face is separated from the light part by the solar terminator.
Details of the Earth–Moon system, showing the radius of each object and the Earth–Moon barycenter. The Moon's axis is located by Cassini's third law.
Due to their tidal interaction, the Moon recedes from Earth at the rate of approximately 38 mm/yr. Over millions of years, these tiny modifications—and the lengthening of Earth's day by about 23 µs/yr—add up to significant changes.[221] During the Devonian period, for example, (approximately 410 Mya) there were 400 days in a year, with each day lasting 21.8 hours.[222]
The Moon may have dramatically affected the development of life by moderating the planet's climate. Paleontological evidence and computer simulations show that Earth's axial tilt is stabilized by tidal interactions with the Moon.[28] Some theorists think that without this stabilization against the torques applied by the Sun and planets to Earth's equatorial bulge, the rotational axis might be chaotically unstable, exhibiting chaotic changes over millions of years, as appears to be the case for Mars.[223]
Viewed from Earth, the Moon is just far enough away to have almost the same apparent-sized disk as the Sun. The angular size (or solid angle) of these two bodies match because, although the Sun's diameter is about 400 times as large as the Moon's, it is also 400 times more distant.[186] This allows total and annular solar eclipses to occur on Earth.
The most widely accepted theory of the Moon's origin, the giant-impact hypothesis, states that it formed from the collision of a Mars-size protoplanet called Theia with the early Earth. This hypothesis explains (among other things) the Moon's relative lack of iron and volatile elements and the fact that its composition is nearly identical to that of Earth's crust.[224]
Earth
EarthBong TongEarth is the third planet from the Sun and the only known planet capable of supporting life. It formed over 4 billion years ago and is a terrestrial planet with significant geological activity like plate tectonics. Earth's atmosphere and oceans were formed by outgassing and volcanic activity and water vapor in the atmosphere condensed to form the oceans. Life first appeared on Earth around 3.5 billion years ago and the planet's biosphere has significantly altered conditions on the surface enabling the proliferation of complex life. Earth interacts gravitationally and magnetically with the Moon and Sun.
Moon
MoonBong TongThe Moon is Earth's only natural satellite and orbits about 384,400 km away. It has a diameter of 3,474.8 km and is tidally locked so the same side always faces Earth. The Moon was formed from debris after a collision between Earth and a Mars-sized object. Its gravitational pull causes ocean tides on Earth and its stabilizing effect on Earth's axis may have enabled the development of complex life.
Origin of ocean basins
Origin of ocean basinsProf. A.Balasubramanian The reason for the occurrence of such a huge mass of water on the globe, is still a myth and reality. The reason goes back to the Origin of Earth itself. The exact mode of origin is not precisely known. Scientists assume, both Primary and secondary sources would have given rise to all both air and water on the earth. Two possible sources as internal source (or) external source have been proposed so far. Some of them are attributed towards the theories of origin of the earth.
The Earth
The EarthUniversidad de NarinoThe document summarizes information about the Earth, including:
1) The Earth began forming 4.6 billion years ago from a hot cloud of gas that condensed into billions of droplets and slowly clumped together due to gravity to form the planet.
2) The Earth's core is mostly iron and its crust is made up of oxygen, silicon, and aluminum.
3) A day on Earth lasts 23 hours, 56 minutes, and 4 seconds, known as a sidereal day, and a full year is 365.24 days, necessitating leap years every four years.

Eearth And Life Sciences - Earth And the Subsystem.pptx
Eearth And Life Sciences - Earth And the Subsystem.pptxLuannPascualDavidThe Earth can be understood as a complex, interconnected system composed of several subsystems. These subsystems, often called Earth’s "spheres," each play a unique role in supporting life and shaping the environment. Here’s a quick overview:
1. The Atmosphere
Description: The layer of gases surrounding Earth, composed mainly of nitrogen, oxygen, carbon dioxide, and other trace gases.
Functions: Regulates Earth's temperature, provides breathable air, protects from harmful solar radiation, and helps distribute weather patterns across the planet.
2. The Hydrosphere
Description: Includes all of Earth's water—oceans, rivers, lakes, glaciers, groundwater, and even atmospheric moisture.
Functions: Essential for life, it supports ecosystems, moderates climate, and is part of the water cycle that recycles and purifies water on Earth.
3. The Lithosphere (or Geosphere)
Description: Comprises Earth's solid outer layer, including the crust and the upper mantle, as well as rocks, minerals, soil, and tectonic plates.
Functions: Provides a habitat for many organisms, influences landforms through tectonic activity, and is the source of natural resources like minerals, oil, and gas.
4. The Biosphere
Description: Encompasses all living organisms on Earth, from single-celled organisms to complex plants and animals.
Functions: Integral to the nutrient cycles, such as the carbon and nitrogen cycles, which sustain ecosystems and biodiversity.
5. The Cryosphere
Description: The frozen component of the hydrosphere, including glaciers, ice caps, and sea ice.
Functions: Helps regulate Earth's temperature by reflecting sunlight (albedo effect), stores fresh water, and influences ocean currents and climate patterns.
6. The Anthroposphere (sometimes included)
Description: Consists of human-made systems, including cities, infrastructure, and all human activities.
Functions: Humans impact all other spheres through agriculture, industry, and urbanization, influencing natural cycles and ecosystems.
Subsystem Interactions
Example: The water cycle (interaction between hydrosphere and atmosphere), where water evaporates, forms clouds, and falls as precipitation, impacting the lithosphere (through erosion) and the biosphere (providing water for organisms).
Carbon Cycle: Involves the biosphere (plants absorb CO₂), atmosphere (carbon is exchanged), and lithosphere (fossil fuels store carbon), demonstrating interconnected feedback loops.
These Earth subsystems are constantly interacting, making Earth a dynamic and evolving planet that supports a wide variety of life forms and ecosystems.

- 1. Earth matters Earth (or the Earth) is the third planet from the Sun and the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the Solar System's four terrestrial planets. It is sometimes referred to as the World, the Blue Planet, or by its Latin name, Terra.] Home to millions of species including humans, Earth is currently the only astronomical body where life is known to exist. The planet formed 4.54 billion years ago, and life appeared on its surface within a billion years. Earth's biosphere has significantly altered the atmosphere and other abiotic conditions on the planet, enabling the proliferation of aerobic organisms as well as the formation of the ozone layer which, together with Earth's magnetic field, blocks harmful solar radiation, permitting life on land. The physical properties of the Earth, as well as its geological history and orbit, have allowed life to persist during this period. The planet is expected to continue supporting life for at least another 500 million years.
