Front

What is the correct order of the Earth's layers from the outside going in?

Back

The correct order is: crust, mantle, outer core, inner core.

Front

Who developed the theory of continental drift?

Back

Front

What is the Earth's crust?

Front

What are the outer core and inner core?

Back

The outer core is a liquid layer composed mainly of iron and nickel, while the inner core is a solid sphere made of iron and nickel.

Front

What evidence supports the theory of continental drift?

Back

Evidence includes the matching coastlines of continents, fossil similarities across continents, and geological formations.

Front

What is Pangaea?

Back

Pangaea was a supercontinent that existed millions of years ago, where all continents were joined together.

Front

How do tectonic plates relate to continental drift?

Back

Tectonic plates are large sections of the Earth's crust that move and can cause continents to drift apart or collide.
