Quiz Terms
What is ridge push?
The sliding of the oceanic lithosphere downward and away from a mid-ocean ridge is due to its higher elevation, which is relevant to subduction zones.
Is the inner core solid or liquid?
Solid
What do convergent boundaries cause?
Earthquakes and mountains.
What's it called when water turns into water vapor?
Evaporation.
What is El Nino?
A band of warm ocean water temperatures that periodically develop off the Pacific coast of South America.
The process by which new oceanic lithosphere forms at mid-ocean ridges as tectonic plates pull away from each other.
How many layers is the Earth composed of and what are they?
Four.... inner core, outer core, mantle, and crust.
What do transform boundaries form?
Faults
What is precipitation?
Water falling to the Earth.
What is La Nina?
The periodic cooling of the ocean surface temperatures in the central and east central of the Pacific.
What is the definition of slab pull?
The gravitational force on dense oceanic lithosphere that forces one plate to slide beneath another.
What is the thickest layer?
Mantle
What boundary causes the most damage?
Convergent
Where does the purest water come from?
Glaciers and ice caps
What are the three impacts of El Nino?
Droughts, floods, crop failures.
What is convection?
The transfer of heat from one place to another caused by the movement of molecules.
What is the outer core composed of?
A mixture of iron and nickel.
Tectonic plates slowly move away from each other as heat from the mantle's convection currents makes the crust less dense.
How is heat energy released from the ocean?
The ocean releases heat through the evaporation process.
How does La Nina affect the south during the winter?
Warmer and drier conditions in the south
What are subduction zones?
How hot is the inner core?
9800 degrees Fahrenheit
What are the three types of plate tectonic boundaries?
Divergent, convergent, and transform.
Where is the largest supply of fresh water found?
Ground water.
Which one has a bigger effect on hurricanes?
El Nino
