8th Grade Earth and Space Science Concepts

Front

What is the Earth's crust compared to in the text?

Back

The Earth's crust is compared to the thin, hard shell of a jawbreaker candy.

Front

What are the two types of Earth's crust?

Back

Continental crust and oceanic crust.

Front

What is the mantle compared to in the text?

Back

The mantle is compared to gooey cheese on a pizza.

Front

What is the outer core made of?

Back

The outer core is made of liquid metal, mostly iron and nickel.

Front

What process creates Earth's magnetic field?

Back

The geodynamo process in the outer core creates Earth's magnetic field.

Front

What is the inner core compared to in the text?

Back

The inner core is compared to the ultimate jawbreaker center that never dissolves.

Front

What is the lithosphere?

Back

The lithosphere is the crust and upper mantle, broken into tectonic plates.

Front

What happens at convergent boundaries?

Back

At convergent boundaries, plates crash into each other, forming mountain ranges, ocean trenches, and volcanic arcs.

Front

What happens at divergent boundaries?

Back

At divergent boundaries, plates move apart, forming new crust, mid-ocean ridges, and rift valleys.

Front

What happens at transform boundaries?

Back

At transform boundaries, plates slide past each other, often causing earthquakes.
