Types of Volcanoes
This type of volcano has explosive, violent eruptions and is shaped like a mountain.
Stratovolcano
When two tectonic plates are moving toward each other.
Convergent boundary
The hard rock layer that makes up both dry land and is covered by the ocean.
Crust
The formation that occurs when two pieces of continental crust come together.
Mountains
The formula for calculating density
D = M/V
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
When two tectonic plates move apart from one another.
Divergent boundary.
The solid, round, iron and nickel ball located in the middle of the Earth.
Inner Core
The formation that occurs on land when a piece of continental crust collides with oceanic crust.
Volcano
This type of crust is more dense.
Oceanic Crust
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
When two tectonic plates slide past one another.
Transform boundary
The liquid (molten) iron and nickel located outside of the inner core.
Outer Core
Deep Ocean Trench
Solve for Density.
Volume = 3cm^3
Mass = 12g
4g/cm^3
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
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
The liquid (molten) rock. Thickest layer of the Earth.
Mantle
Mid-Ocean Ridge
The density of water
1g/cm^3
This volcano type is formed the top of a volcano collapses in and creates a giant crater in the middle.
Caldera
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
The two types of crust.
Continental crust
Oceanic crust
The formation that occurs when two pieces of continental crust pull apart.
Rift Valley
