Answer:
The tectonic plates are continuously moving and earthquakes are happening all the time.
Explanation:
An earthquake is the seismic waves travelling through the lithosphere. They occur along tectonic plate boundaries and faults. In areas that are far from these plate boundaries and faults, earthquakes are less likely to be felt. The size of the earthquake is mostly unnoticeable. Bigger earthquakes happen with a build of tension that is suddenly released. It does not happen as often because it takes time to build up the pressure.
Answer:
True
Explanation:
They were made into carbon after millions of years from buried remains from plants and animals that lived millions of years ago. This caused the coal and oil to be carbon based fuels.

Answer:
c. The downgoing slab takes along water, and that water lowers the temperature at which rock melts to allow melting in and near the slab.
Explanation:
A subduction zone occurs when one of the plates at convergent boundaries, an area where tectonic plates meet, is an oceanic lithosphere.
These oceanic plates are high in temperature on formation but as they cool, they descend into the mantle below. This descent applies pressure until water is liberated from the lowering crust. The water in turn rises into the surrounding mantle and lowers the temperature at which the rocks melt to produce magma which are partly melted rocks.
This liberation of water from the subducting crust and accompanying melting is responsible for the formation of almost all magma at subduction zones.
Answer:
In the ocean where new crust is being created at a divergent plate boundary.
Explanation:
The crust mainly form the bottom of the oceans which is constantly forming along the mid oceanic ridges.The mid ocean ridge is the boundary between tectonic plates and it is the place where the plates spreads apart from each other.
The hot magma in the underlying layer gradually cools down and transform into a solid form which ultimately form the new ocean crust that gradually pushed away from the ridge by more new crust.
This spreading produce upto 2-6 inches of new crust per year.
