Crustal Formations
Density
100

This type of volcano has explosive, violent eruptions and is shaped like a mountain. 

Stratovolcano

100

When two tectonic plates are moving toward each other.

Convergent boundary

100

The hard rock layer that makes up both dry land and is covered by the ocean.

Crust

100

The formation that occurs when two pieces of continental crust come together.

Mountains

100

The formula for calculating density

D = M/V

200

This type of volcano is the tallest type and made from slow flowing lava coming from the bottom of the ocean. They form over hot spots.

Shield Volcano

200

When two tectonic plates move apart from one another.

Divergent boundary.

200

The solid, round, iron and nickel ball located in the middle of the Earth.

Inner Core

200

The formation that occurs on land when a piece of continental crust collides with oceanic crust.

Volcano

200

This type of crust is more dense.

Oceanic Crust

300

This volcano is usually a few hundred feet to about a thousand feet tall and known for the large chunks of lava that it ejects when erupting.

Cinder-Cone Volcanoes

300

When two tectonic plates slide past one another.

Transform boundary

300

The liquid (molten) iron and nickel located outside of the inner core. 

Outer Core

300
The formation that occurs in the ocean when oceanic crust collides with continental crust.

Deep Ocean Trench

300

Solve for Density.

Volume = 3cm^3

Mass = 12g

4g/cm^3

400

This type of volcano is formed from cracks in the bottom of the ocean floor. They result in the new oceanic crust being formed. 

Fissure volcano

400

The theory that suggests the Earth's crust is broken into pieces like a puzzle and move around the Earth's surface creating new crustal formations. 

The Theory of Plate Tectonics

400

The liquid (molten) rock. Thickest layer of the Earth.

Mantle

400
The formation that occurs when two pieces of ocean crust pull apart. 

Mid-Ocean Ridge

400

The density of water

1g/cm^3

500

This volcano type is formed the top of a volcano collapses in and creates a giant crater in the middle. 

Caldera

500

The driving force that causes the Earth's crust (plates) to slowly move, shift position, and create new crustal formations. This occurs in the mantle.

Convection Currents

500

The two types of crust.

Continental crust

Oceanic crust

500

The formation that occurs when two pieces of continental crust pull apart.
