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.

What are two things that support the continental drift theory?
Two things that supports the continental drift theory are; 1. Fossil. 2. Continent Shapes.
Why do all coast look different?
Coastlines look different due to variations in geological processes, such as erosion, deposition, and tectonic activity. Factors like wave action, sediment type, and sea level changes also contribute to the diverse shapes and features seen along coastlines. Additionally, human activities like development and engineering can further alter the appearance of coastlines.
What scientist proposed the first formal theory of continental drift?
Continental Drift was put forward by Alfred Wegener.(1880-1930). One piece of evidence on which he based his ideas was the similarity of shapes of the South American and African coastlines. Another was the fact that the same types of fossil are found in both places.
Can you describe 3 clues that support the idea of continental drift?
Fit of the continents: The way the continents' coastlines fit together like puzzle pieces suggests they were once connected. Matching rock formations: Similar rock formations, mountain ranges, and geological features on different continents provide evidence of a shared history. Fossil evidence: The presence of the same fossils on continents that are now separated by vast oceans indicates that they were once part of the same landmass.
What might affect the shapes of rivers and coastlines?
Factors such as erosion, sediment transportation, tectonic movements, and sea level changes can influence the shapes of rivers and coastlines. Erosion by water can carve out valleys and form meanders in rivers, while coastal features like cliffs and beaches can be shaped by the power of waves and currents. Tectonic movements can also create or alter the topography of river valleys and coastlines over long periods of time.
How do the shapes of different coastlines support continental?
fossils of once living things provide clues that support contenental 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.
Why do all coast look different?
Coastlines look different due to variations in geological processes, such as erosion, deposition, and tectonic activity. Factors like wave action, sediment type, and sea level changes also contribute to the diverse shapes and features seen along coastlines. Additionally, human activities like development and engineering can further alter the appearance of coastlines.
