Plate Boundaries
How many types of plate boundaries are there?
There are 3 boundaries.
Is oceanic crust denser than continental crust?
Where are volcanos located?
Abyssal Plains
What plate boundary moves away from each other?
Divergent Boundaries
What causes convection currents?
The Earth's core heating the mantle
what are the names of the plate boundaries?
1. Convergent
2. Divergent
3. Transform
True or False: Gravity pulls the older and denser crust from the mid-ocean ridge to the trenches.
True
Yes or no: Does plate movement cause mountains, volcanoes, earthquakes, etc?
What plate boundaries crash into each other?
Convergent Boundaries
What does subduction do?
It is when a plate slide under another and it forms new crust.
What type of plate boundary cause earthquakes?
Transform
Where is oceanic crust found?
It is found in the oceans, above the upper mantle.
What type of plate movement causes Rift Valleys?
The plates moving apart.
what forms due to divergent boundaries?
Mid-Ocean Ridges and rift valleys.
What state is the most known earthquake-prone area?
California
What plate boundary slip and slide past each other?
Transform
Where is continental crust found?
On the land above the water.
What is the longest running chain or under water mountains?
What is formed due to convergent boundaries?
what is sea floor spreading?
New material adding to the sea floor.
What plate boundary slide into each other?
Convergent
What are the types of crust?
Oceanic vs. Oceanic
Oceanic vs. Continental
Continental vs. Continental
Where does the sea floor spreading begin?
It starts at the Mid-Ocean Ridge.
What is the difference between convergent and divergent boundaries?
The way they move is different (Convergent crash into each other, while divergent move away from each other) and the landforms that are created (Convergent makes volcanoes, mountains, and ocean trenches, while divergent makes mid-ocean ridges and rift valleys).
How does magma affect the se floor?
Molten magma rises through the plates, forming mid-ocean ridges, underwater volcanoes, hydrothermal vents, and new ocean floor crust.
