How do the shapes of different coastlines support continental drift?
The shapes of different coastlines can provide evidence for continental drift because some coastlines on different continents appear to fit together like pieces of a jigsaw puzzle. For example, the coastlines of South America and Africa have similar shapes and can be fitted together. This suggests that these continents were once joined together and later drifted apart.
How do continental coastlines prove continental drift?
Continental coastlines provide evidence for continental drift through their complementary shapes and geological features. For example, the eastern coast of South America aligns closely with the western coast of Africa, suggesting that these landmasses were once joined. Additionally, similar fossil records and rock formations found on both sides of the Atlantic Ocean support the idea that continents have moved apart over geological time. This alignment of coastlines and shared geological characteristics reinforce the theory of continental drift.
What evidence do we have for continental drift?
Evidence for continental drift includes the matching shapes of coastlines across different continents, similarities in rock formations and geological features between continents, and the distribution of fossils of the same species on different continents that were once connected. Additionally, the alignment of mountain ranges and earthquake patterns also support the theory of continental drift.
What do the shapes of the continents now tell us about their past?
The shapes of the continents suggest that they were once connected as a single landmass known as Pangaea, which later drifted apart due to the movement of tectonic plates. The matching coastlines and geological evidence support the theory of continental drift and plate tectonics.
Which 2 continents are used as evidence for the continental puzzle?
Africa and South America were used as evidence for the continental puzzle due to the matching shapes of their coastlines and geological similarities such as rock formations and fossils found on both continents. This helped support the theory of continental drift proposed by Alfred Wegener in the early 20th century.
How does the map support the theory of continental drift?
The shapes of continents appearing on the map clearly show similar shapes and how the continents might fit together.
What are two things that support the continental drift theory?
Two things that supports the continental drift theory are; 1. Fossil. 2. Continent Shapes.
The shapes of which two continents' coastlines led to early suggestions they had been joined at one time?
The shapes of the coastlines of South America and Africa led to early suggestions that they had been joined at one time. This idea eventually became known as the theory of continental drift and was later supported by the development of the theory of plate tectonics.
What is Alfred wegener's evidence on climate?
Alfred Wegener's evidence for his theory of continental drift included similarities in the shapes of the coastlines of continents, the distribution of fossils across continents, and the matching geological features on different continents. These provided support for the idea that the continents were once connected and have moved over time, influencing climate patterns.
Why don't present shapes of the continents fit perfectly into a supercontinent?
One reason is because the Coastlines of land masses change over time. If you map the edges of the continental shelves, the fit is much better.

Which 2 continents fit together the best?
South America and Africa are often considered to fit together well due to their similar shapes along the Atlantic Ocean coastlines. This observation was one of the key pieces of evidence used to support the theory of plate tectonics and the concept of continental drift.
