The document describes the four main layers of the Earth: the crust, mantle, outer core, and inner core. The crust is the outermost layer and makes up only 1% of the Earth. It is broken into tectonic plates. The mantle is the largest layer located below the crust and is divided into upper and lower sections. The outer core is liquid and made of iron, while the inner core is solid due to extreme temperatures and pressures. Increasing human population has impacted the lithosphere by deteriorating this essential layer that supports life through resources and environmental functions.
3. Earth LayersEarth Layers
The Earth is divided into four main
layers.
*Inner Core
*Outer Core
*Mantle
*Crust
4. The CrustThe Crust
* The Earths crust is like
the skin of an apple. It
is very thin compared to
the other three layers.
*The crust makes up 1% of
the Earth.
* The crust of the Earth
is broken into many
pieces called plates.
6. The MantleThe Mantle
The mantle is the layer
below the crust.
The mantle is the
largest layer of the
Earth.
The mantle is divided
into two regions: the
upper and lower
sections.
7. Outer CoreOuter Core
* The core of the Earth
is like a ball of very
hot metals.
* The outer core is
liquid.
* The outer core is made
up of iron and is very
dense.
8. Inner CoreInner Core
* The inner core of the
Earth has
temperatures and
pressures so great
that the metals are
squeezed together and
are not able to move.
* The inner core is a
solid.
9. Human Impact on Lithosphere
The lithosphere is vital to life on earth. It supports the
food webs that maintain life it provides us with a vast
collection of natural resources, and it plays a vital role in
the purification of the water we drink. We also depend
on it to dispose of some of our wastes. The increasing
population within the world has had an impact on the
lithosphere and consequently as led to the deterioration
of this essential component of the biophysical
environment.
