Earths Layers and Plate Tectonics Review

Front

What is the main process that formed the Hawaiian Islands?

Back

The Hawaiian Islands were formed by hot spots and volcanic eruptions.

Front

What does the presence of earthquakes and volcanic eruptions in the Ring of Fire indicate?

Back

It indicates that the edges of the tectonic plates are moving in this area.

Temperature increases as you go deeper into the Earth.

Front

Which layer of the Earth is characterized by rock that is plastic and can flow?

Back

The asthenosphere is characterized by rock that is plastic and can flow.

Front

What are the two types of crust that the Earth has?

Back

The two types of crust are Oceanic Crust and Continental Crust.

Front

What is the outermost layer of the Earth called?

Back

The outermost layer of the Earth is called the crust.

Front

What is the layer beneath the crust that is solid and rigid?

Back

The layer beneath the crust that is solid and rigid is called the lithosphere.

Front

What is the mantle?

Back

The mantle is the layer of the Earth located between the crust and the core, composed of semi-solid rock.

Front

What is seafloor spreading?

Back

Seafloor spreading is the process by which new oceanic crust is formed at mid-ocean ridges and older crust is pushed away.

Front

What is a tectonic plate?

Back

A tectonic plate is a large slab of solid rock that makes up the Earth's lithosphere and moves over the asthenosphere.
