German geologist who theorized the continents were once all together then slowly drifted apart.
Who is... Alfred Wegener
When 2 plates are moving towards each other?
What is... Convergent
The large, chain of mountains in the Atlantic ocean is called...
What is.. Mid-Atlantic Ridge
This type of crust is MORE dense than the other. (Continental or oceanic)
What type of boundary causes Sea Floor Spreading?
Why was Wegener's Theory not supported?
When 2 plates slide passed each other.
What is... Transform
What is... Trench
This type of crust is LESS dense
What is... Continental
What type of landform caused Hawaii to form?
What is.. Hotspot
The theory that all continents were once together then slowly drifted apart.
What is... Theory of Continental Drift
What type of plate boundary is associated with major earthquakes?
What is... Transform
Highly explosive volcanoes that do not erupt often so they are able to grow very large.
What are.. Composite
The latter of Earth makes up the crust and top part of the mantle. It is very brittle and broken up into plates.
What is... Lithosphere
Where is the newest crust in the ocean?
Where is.. the ridge
What are the broken segments that make up the lithosphere?
What are.. Plates
Volcanoes along coastlines form as a result of which type of boundary?
What is... Convergent (Continental + Oceanic)
Non-Explosive volcanoes that have gently sloping sides. Lava is NOT viscous.
What is... Sheild
This type of crust is very fluid, the plates float on top of it. Makes up the rest of the mantle
What is... Asthenosphere.
What is it called when Continental crust goes underneath oceanic.
What is... Subduction
What are the name of the currents of heat that cause our plates to move?
What is... Convection
Non-volcanic mountains form along which type of boundary?
What is... Convergent (Continental + Continental)
Area around the Atlantic ocean where there is a ton of volcanic activity.
What is.. Ring of Fire.
Process that continuously adds new crust to the ocean floor.
What is.. Seafloor spreading
