Continental Drift and Evidence

Front

What is continental drift?

Back

Continental drift is the movement of the Earth's continents relative to each other.

Front

Name one piece of evidence that supports continental drift.

Back

The presence of similar fossils on different continents.

Front

How do fossils provide evidence for continental drift?

Back

Fossils provide evidence for continental drift by showing similar species on now-separated continents, indicating they were once connected.

Front

Which two continents are known to have similar fossils?

Back

South America and Africa

Front

What was the name of the supercontinent that existed millions of years ago?

Back

Pangaea

Front

How do scientists determine the past positions of continents?

Back

Scientists determine the past positions of continents by studying plate tectonics, fossil distribution, paleomagnetism, and geological evidence.

Front

What role do tectonic plates play in continental drift?

Back

Tectonic plates facilitate the movement of continents, leading to continental drift.

Front

Can you name a type of rock that supports the theory of continental drift?

Back

Basalt

Front

How does the distribution of plants support the idea of continental drift?

Back

The distribution of similar plant species across continents indicates that continents were once joined, supporting the theory of continental drift.

Front

What is the significance of the Mid-Atlantic Ridge in understanding continental drift?

Back

The Mid-Atlantic Ridge provides evidence for continental drift by showing how tectonic plates move apart and create new crust.
