Plate Boundaries

What are the three types of plate boundaries?

• Divergent, Convergent, Transform

• Continental, Oceanic, Transform

• Subduction, Collision, Rift

• Mountain, Island, Earthquake

What happens when two plates of continental crust collide?

• Mountains are formed

• Volcanoes are formed

• Island arcs are formed

• Earthquakes occur

What happens when a plate of ocean crust collides with a plate of continental crust?

• The ocean crust subducts under the continental crust

• The continental crust subducts under the ocean crust

• The ocean crust melts and creates an island arc

• The continental crust melts and creates a mountain range

What happens when two plates of oceanic crust collide?

• The older plate subducts under the younger plate

• The younger plate subducts under the older plate

• The crust melts and creates a mountain range

• The crust melts and creates an island arc

What happens at divergent boundaries?

• Two plates move away from each other

• Two plates collide with each other

• Two plates move past each other horizontally

• Two plates sink under each other

What would you be most likely to find at a transform boundary?

• Earthquakes
• Volcanoes
• Mountains
• Rift

How do mountains form?

• An ocean plate sinks beneath another plate and begins to melt, sending melted rock to the surface, which forms volcanic mountains or islands.
• Hot rock from within the earth risies through ocean floor as plates separate. This forms a volcanic mountain chain, or ridge, on the ocean floor.
• Two continental plates collide, and the land folds and crumples like paper.
• All of the above.

Plates that diverge or move apart from each other

• divergent

• transform

• convergent

• lithosphere

Organize the Layers from the Surface to the Deepest.

• Crust

• Inner Core

• Outer Core

• Mantle

How does temperature change as you move from the crust to the core?

• it gets cooler

• it gets hotter

• it stays the same

• the core is frozen
