The outermost layer of the Earth. Ranging from 5 to 100 km thick, it is also the thinnest layer of the Earth
What is crust
100

Pieces of the lithosphere that move around on top of the asthenosphere

What are tectonic plates

100
When two tectonic plates collide at this boundary
What is a Convergent boundary
100

Define Seismology

What is the study of earthquakes

100

What is a crack in earth's crust?

 fault

200
Is the layer of the Earth between the crust and the core.
What is the mantle.
200
Is the theory that continents can drift apart from one another and have done so in the past
What is Continental Drift
200
A boundary where the plates pull apart
What is a divergent boundary
200

A vent in earth's crust where magma is released

What is a volcano

200
What is the ice layer on top of the crust

What is a glacier

300
Made mostly of Iron and small amounts of nickle. it extends from the bottom of the mantle to the center of the Earth.
What is the core
300

Why did people not believe Alfred Wegner and his theory of continental drift

He could not explain how the continents moved

300

The process that hot material from deep within the Earth rises while cooler material near the surface sinks/ magma moving due to density

What is Convection

300

What is measured with the magnitude of and earthquake

What is its strength

300

What do volcanologists study?

Volcanoes
400
The outermost rigid layer of the Earth is made of two parts the crust and the rigid upper part of the mantle
What is the Lithosphere
400

The edges of tectonic plates are called

Plate boundaries

400
A boundary where the plates slide past each other
What is a transform boundary
400

What is measured with the intensity of an earthquake

How much it is felt and the damage reported

400
What are 2 types of crust?

Continental and Oceanic

500
Soft layer of the mantle on which pieces of the lithosphere move
What is the Asthenosphere
500

This is the nickname for where the majority of Earth's earthquakes and volcanoes occur

What is Ring of Fire

500

When two plates collide, the plate with MORE density will do what

The plate will sink under the other plate

500

A volcano with calm lava flows

What is a nonexplosive volcano

500

What is technology (SONAR, RADAR, Satellites)
