Geology Part 1

Front

What is the inner core of the Earth?

Back

The inner core is the solid, innermost layer of the Earth, composed mainly of iron and nickel, and is extremely hot.

Front

Who proposed the theory of Continental Drift?

Back

Alfred Wegener proposed the theory of Continental Drift, suggesting that continents were once connected and have since drifted apart.

Front

How do scientists estimate the thickness of Earth's layers?

Back

Scientists estimate the thickness of Earth's layers by studying seismic waves, which are generated by earthquakes.

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates move towards each other, often causing one plate to be forced below the other.

Front

What is the outer layer of the Earth called?

Back

The outer layer of the Earth is called the crust.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the upper part of the mantle.

Front

What are seismic waves?

Back

Seismic waves are waves of energy that travel through the Earth, often caused by earthquakes, and are used to study the Earth's interior.

Front

What is the mantle?

Back

The mantle is the thick layer of rock between the Earth's crust and outer core, composed of silicate minerals.

Front

What is a transform plate boundary?

Back

A transform plate boundary is where two tectonic plates slide past each other horizontally, causing earthquakes.

Front

What is the core of the Earth?

Back

The core is the innermost layer of the Earth, consisting of a liquid outer core and a solid inner core, primarily made of iron and nickel.
