Earth Science Flashcard

Front

What causes Earth to be tectonically active?

Back

Earth’s solid surface layer sits on a layer of semimolten rock that slowly flows.

Front

What type of boundary interaction formed the Himalayan Mountain Range?

Back

Convergent boundary between two continental plates.

Front

How does Earth's rotation affect life on Earth?

Back

It creates the magnetosphere, which diverts high-energy particles from space away from Earth’s surface.

Front

Where is the youngest rock located on the floor of the Atlantic Ocean?

Back

Close to the top of the mountains on both sides of the Mid-Atlantic Ridge.

Front

What property of Earth’s interior keeps the innermost part in a solid state?

Back

Extremely high pressure.

Front

What is a divergent boundary?

Back

A tectonic plate boundary where two plates move away from each other.

Front

What is a convergent boundary?

Back

A tectonic plate boundary where two plates collide or move towards each other.

Front

What is the Mid-Atlantic Ridge?

Back

A divergent fault on the floor of the Atlantic Ocean that forms a mountain chain.

Front

What is the significance of the magnetosphere?

Back

It protects Earth from high-energy particles from space.

Front

What is the role of pressure in Earth's interior?

Back

High pressure keeps the innermost part of Earth in a solid state despite high temperatures.
