Alfred Wegener proposed the theory of continental drift in 1912, which stated that around 250 million years ago, all the continents were joined together in a supercontinent called Pangaea, and have been gradually drifting apart to their current positions. As evidence, the continents appear to fit together like puzzle pieces, the same plant and animal fossils are found on different continents' coastlines, identical rock formations and sequences are found across separated continents, and tropical plant remains have been discovered in Antarctica along with evidence of simultaneous glaciation in other modern landmasses. However, the theory lacked a proposed mechanism for continental movement and was not widely accepted by the scientific community at the time.

Alfred Wegener proposed the theory of continental drift in the early 20th century, which suggested that the Earth's continents were once joined together in a supercontinent called Pangaea but have since drifted apart over millions of years. This helped explain the existence of similar fossils and rock formations across continents now separated by oceans. However, it took many years for Wegener's idea to become widely accepted among the scientific community.Theory of land bridges

The document discusses three theories of ancient land bridges that were proposed to explain similarities between species on different continents:
1) The Atlantic Land Bridge between Africa and South America was thought to explain shared species like monkeys and ostriches, but zoological evidence shows the species are unrelated and the land bridge is unlikely.
2) Lemuria was proposed to explain lemurs in Madagascar and lorises in India, but lemurs and lorises are unrelated and fossil evidence shows their ancestors lived elsewhere.
3) The Antarctica Land Bridge between Australia and South America was suggested for marsupials and frogs, but there is no fossil or living evidence of these species in intervening areas, so this landOutline: Chapter 14.1: The Continental Drift Hypothesis

Continental Drift Theory proposed that the continents were once joined together in a single landmass called Pangaea. Evidence for this theory included:
1) The matching coastline edges of continents like Africa and South America, and geological features that lined up across continents.
2) Similar fossil species found in matching geological formations along coastlines now separated by oceans.
3) Identical aged rock formations and tillite deposits along the separated coastlines, indicating they were once attached.
This theory was initially rejected due to the lack of an explained physical mechanism for continental drift, but was later supported by the development of plate tectonic theory.Chapter 14.1: Continental Drift Hypothesis

This document summarizes Alfred Wegener's continental drift hypothesis from the early 20th century. It discusses how Wegener proposed that the continents were once joined together in a supercontinent called Pangaea, which later broke apart and drifted to their current positions. The document provides evidence that Wegener used to support his hypothesis, including the apparent fit of continental coastlines, fossil correlations between separated continents, and matching geological formations. However, Wegener's idea was controversial at the time because he could not explain the mechanism of continental motion. It was not until the development of plate tectonic theory that scientists fully accepted the concept of continental drift.Field assignment Ouellette

The Big Island of Hawaii was formed by volcanic activity from a hot spot under the Pacific tectonic plate over the last 10 million years. The oldest islands formed over 5 million years ago, while the Big Island itself formed around 500,000 years ago. The Big Island contains 5 volcanoes, 3 of which are still active including Kilauea, the most active volcano which has erupted as recently as 2011. Lava rock layers on the Big Island show the island's geological formation over time as lava flows from the volcanoes to the ocean.Continental drift

- Alfred Wegener developed the hypothesis of continental drift in 1910, proposing that the continents were once joined together in a supercontinent called Pangaea before drifting apart. This idea is known as continental drift.
- Wegener provided evidence from matching fossil distributions, rock formations, and past climate patterns between continents now separated by oceans that supported his hypothesis of continental movement over time.
- However, Wegener's hypothesis was rejected by most geologists in the early 1900s due to lack of mechanisms to explain continental motion and discrepancies with existing geological theories. It was not widely accepted until new evidence emerged in the 1950s.

Alfred Wegener proposed the theory of continental drift, which stated that the Earth's continents were once joined together in a supercontinent called Pangea before slowly drifting apart over hundreds of millions of years. Wegener supported this theory with three types of evidence: matching landforms between continents, fossils of the same plants and animals found on separated continents, and evidence that climates had changed in ways consistent with continental movement rather than climate change alone. This evidence convinced many of the accuracy of Wegener's theory of continental drift.Drifting continents powerpoint

It describes how Wegener proposed that the continents were once joined together in a supercontinent called Pangaea, which later broke apart and drifted to their current positions. It provides details on Wegener's evidence, including the fit of continental coastlines, locations of past glaciations, distribution of climatic belts and fossils, and matching geological units. However, Wegener's theory received criticism at the time for not adequately explaining the forces driving continental drift.See this and learn about Continental Drift Theory

According to the continental drift hypothesis, the continents have slowly moved over time to their current positions. Alfred Wegener first proposed this theory in 1912. Seafloor spreading provided insight into the mechanism of plate tectonics, with magma pushing the plates apart at mid-ocean ridges and subduction zones pulling them under. About 225 million years ago, nearly all land was part of the supercontinent Pangaea, which has since broken apart, forming the continents in their current positions.Continental Drift

1) Alfred Wegener proposed the theory of continental drift, which suggested that the continents were once joined together in a supercontinent called Pangaea before drifting apart over millions of years.
2) To support his theory, Wegener presented four pieces of evidence: the matching shapes of continental edges, identical fossil distributions, matching rock formations, and evidence of past climate zones that no longer align with the continents' current locations.
3) Despite this evidence, Wegener's contemporaries rejected his theory because he could not explain the mechanism that caused the continents to move. Acceptance of the theory required understanding how and why continental drift occurred.Continental Drift Notes - Jenny

Alfred Wegener proposed the theory of continental drift in the early 1900s, which suggested that the continents were once joined together and have since drifted apart over millions of years. This helped explain similarities in fossils and rock formations across continents. Though initially lacking evidence, Wegener's theory is now widely accepted due to evidence like matching coastlines, fossil and rock matches between continents, and the fit of continents across oceans. The supercontinent Pangaea broke apart into Gondwana and Laurasia around 200 million years ago.Theory of Continental Drift Science Presentation in Green Light Yellow Flat G...

Over 70% of the Earth's surface is covered by oceans, with the remaining 29% comprised of continents. Most continents have their bases in the northern hemisphere and extend southward. Alfred Wegener first proposed the continental drift theory in 1912, suggesting that all landmasses were once joined together in a supercontinent called Pangaea, surrounded by a single ocean called Panthalasa. Pangaea later broke apart into separate continents, including Laurasia and Gondwana, as evidenced by matching coastlines, mountain systems, fossils, and plant and animal distributions between separated lands. The theory of plate tectonics later expanded on drift by explaining the Earth's lithospheric plates that move and interact at boundariesContinental drift
Continental driftSaba Jamal Din
?
Continental drift is the slow movement of continents across the Earth's surface due to tectonic plate motions. Evidence for continental drift includes: the matching coastlines of separated continents; matching fossil, rock, and glacial deposits in separated areas; and paleomagnetic data showing continents were once joined. Alfred Wegener first proposed the continental drift theory in 1915, though it was not widely accepted until the 1960s when seafloor spreading was discovered, providing evidence of plate tectonics and explaining the driving force behind continental drift.Recently uploaded (20)
