Plate Boundaries
What plate boundary occurs when two plates collide?
Convergent
What is the outer most layer of the earth called?
Crust
There is none
What is the beginning of the rock cycle?
There is none
Almost all volcanoes form because of this process.
Subduction
What plate boundary occurs when two plates separate?
Divergent
What is the center of the earth called?
Where does the carbon come from that gets absorbed by trees?
The atmosphere
How do rocks get destroyed?
Subduction or weathering
These occur at all plate boundaries
Earthquakes
What plate boundary occurs when two plates collide?
Transform
What layer of the earth contains the convection currents that causes the plates to move?
The Mantle
When plants and animals die and decompose; where does their carbon go?
The geopshere
How do new rocks get made?
Volcanic eruptions or cooling of magma
What are almost all volcanoes called mountains on a map?
No one would want to live next to a volcano
What two features are created when 2 oceanic plates collide?
Volcanic Islands and a Trench
As you go further into the earth, what happens to the pressure?
It increases
When power plants, cars, or other burners of fossil fuels burn fuel; where does their carbon go?
The atmosphere
When rocks undergo high heat and pressure, but dont melt... what rock is made?
Metamorphic
Hawaii is not on a convergent boundary, what formed those islands?
A hot spot
What causes the plates to move?
The heat from the core creates convection currents in the mantle which move the plates.
As you go further into the earth, why does the temperature increase?
Because all the layers act as insulation and trap the heat.
Why is the carbon cycle out of balance?
We burn too much fossil fuels and cut down too many trees.
When rocks are weathered and destroyed over hundreds of years... what do they become?
Soil
Almost 75% of all volcanoes are found here
Ring of Fire
