Some is fossil heat, some from radioactivity.

For convection currents in the asthenosphere where does the heat come from?
The bottom of the Earth. :)
In what layer does plasticity and convection occur?
They occur in the upper mantle and the convections come from the inner core but travel to the upper mantle.
What is the force thought to move large pieces of earths crust including the continents?
Convection-currents in the Mantle, and spreading-ridge pressure from the emerging basalt along constructive plate boundaries. The processes come under the general heading of 'Plate Tectonics'.
Where does the energy found in earth's interior come from?
from convection and the heating
What are rocks that come from the mantle called?
Igneous rock.
Where does the heat come from that drives convection current the mantle?
uneven temperatures
Where does the heat come from that drives this convection current the mantle?
The heat comes from the outer core, which provides the heat.
Can the continents come together again?
It is highly unlikely for the continents to come back together as they were before due to the movement of tectonic plates. However, some theorize that in around 250 million years, a new supercontinent could form as a result of the ongoing process of plate tectonics.
What are the forces that drives the tectonic plates of the earth?
There are many possible forces or mechanism associated by continental movement.include;sea-floor spreadingthermal plume phenomenaslab-push at mid oceanic ridge.slab-pull at subduction zoneNote that all this mechanism work together

Where does the energy that drives surface currents come from?
Wind

What causes convection currents and what causes them?
Convection currents are caused by heat dispersal which results in the circulation of material such as air, water, or earth's mantle. Once hot air (or gas) has begun to move, it pushes against adjacent air, mixing until that air reaches the same temperature. Just as you have a cold room with a space heater. Turn it on without a fan, and come back later, the hot air has pushed itself around and warmed the cool air around it.
What are magma and gas vents?
magma is basiclly lava but it is called lava when its under ground and then called lava when its above ground the convection currents in the mantle ( soft rock part of earth under crust) causes the magma to rise and come out of the gas vent which is also known as crater the opening at the top of tge volcano
