Layers of the Earth
The center of the earth is the
Inner Core
When two tectonic plates come together it is called
Convergent Boundary
Explain what a Geologic Process is
Something that changes features on the land
Convergent boundaries create features called
Mountains
Ocean Trenches
What causes the plates to move?
Convection
The layer underneath the crust is called
The mantle
When two plates separate from each other it is called
Divergent Boundary
What are two ways that weathering can break something down?
Water (Rain, waves)
Wind
Chemical (Acid rain)
Transform plate boundaries create
Faults
Earthquakes
What broke Pangaea apart
Plate tectonics, or plate movement
Below the lithosphere is a moving layer of magma called
Asthenosphere
Describe a transform plate boundary
When two plates slide past each other
Describe what deposition is and how it can change the land
Dropping off soil
It can create islands, new beaches, deltas, increase the shoreline
Divergent plate boundaries create features called
Volcanic Islands
Ridges (Underwater Mountain Chains)
A piece of equipment used to record movement in the plates is called
Seismograph
How does heat move during convection?
Hot material rises, cold material sinks
It moves in a circular current
What was the name of the super-continent that once existed as a combination of all continents together
Pangaea
Where does a volcano get its lava?
The asthenosphere or upper mantle
Not the mantle itself
Tsunamis are most often caused by
Underwater plate movement
There are S and P waves. Which one is faster and which one causes more damage
P Wave is faster, but the S wave causes more destruction
The crust and upper mantle together are called the
Lithosphere
Earthquakes and volcanoes happen most often around the Northern Pacific Ocean. What is this area called?
Ring of Fire
How does erosion affect people living near the beach?
The wind and waves move the soil/sand off the beach. This can collapse the land and destroy homes.
What is an epicenter
The vertical point above an Earthquake
The point above where the Earthquake started
Plants in the soil can hold the soil together and stop the water from removing it
