As you travel from the inner core to the crust, how would temperature, pressure and density of the material change?
Nothing, the layers are made of the same material throughout.
Temperature would decrease, but pressure and density would increase.
Pressure and density would increase, but temperature would increase.
Temperature, pressure, and density would all decrease.

Asthenosphere
Lithosphere
Moho discontinuity
Continental crust
Which layer(s) of the Earth make up the asthenosphere?
Only the crust

Active volcano
Dormant volcano
Extinct volcano
Neutral volcano
In what areas on Earth are volcanoes mainly found?
Plates collide
Rivers are found
Mountains are found
Plates fit together perfectly
Why is the Philippines prone to volcanic eruptions and earthquakes?
Because it is where volcanoes originated

Why do earthquakes usually occur at plate boundaries?
The rocks on the edges of the plates are soft
The rocks near the plates experience little stress
The rocks near the plates experience great pressure
The boundaries between plates have been active for many years
