Pre-Test Earth Systems 3

Front

What is the Ring of Fire?

Back

The Ring of Fire is a region in the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur, primarily due to tectonic plate boundaries, especially convergent boundaries.

Front

What type of boundary is responsible for the formation of ocean trenches?

Back

Convergent boundary.

Front

What are the four layers of the Earth in order from most dense to least dense?

Back

Inner core, outer core, mantle, crust.

Front

Can any rock turn into any other kind of rock?

Back

True.

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 is the asthenosphere?

Back

The asthenosphere is the semi-fluid layer of the mantle beneath the lithosphere, allowing tectonic plates to move.

Front

What causes tectonic plate movement?

Back

Convection currents in the mantle.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, often resulting in the formation of new crust.

Front

What is a transform boundary?

Back

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

Front

What is the difference between the inner core and outer core?

Back

The inner core is solid and composed mainly of iron and nickel, while the outer core is liquid and also composed of iron and nickel.
