Amplify Plate Motion Lesson 1.2 & 1.3

Front

What is the Earth's crust made of?

Back

The Earth's crust is made of hard solid rock.

Front

Where can geologists find hard solid rock?

Back

Geologists can find hard solid rock at Sites 1 and 2 because all of the crust is made of hard solid rock.

Front

What happens when tectonic plates collide?

Back

When tectonic plates collide, people in the surrounding area feel an earthquake.

Front

What type of cross section is needed to determine a tree's age?

Back

A horizontal cross section is needed to determine a tree's age.

Front

What does finding basalt rock in a core sample imply?

Back

Finding basalt rock in a core sample implies that the crust at that location was formed through volcanic activity.

Front

What is a tectonic plate?

Back

A tectonic plate is a large slab of solid rock that makes up the Earth's crust.

Front

What is the significance of earthquakes in relation to plate tectonics?

Back

Earthquakes are significant because they indicate the movement and collision of tectonic plates.

Front

What is volcanic activity?

Back

Volcanic activity refers to the processes and phenomena associated with the movement of magma from beneath the Earth's crust to the surface.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural forces such as wind or water.

Front

What is a core sample?

Back

A core sample is a cylindrical section of soil or rock taken from the ground to study its composition and structure.
