Answer:
160790 J
Explanation:
We can find the heat necessary for the ice to go from -20 degrees Celsius to 0 degrees Celsius:
Where 
is the specific heat of ice, that is the amount of heat that must be supplied per unit mass to raise its temperature in a unit.
We must calculate the latent heat of fusion required for this ice mass to change to water:
Where H=334 J/g is the specific latent heat of fusion of water, that is the amount of energy needed per unit mass of a substance at its melting point to change from the solid to the liquid state.
Then we calculate the heat necessary for the water to go from 0 degrees Celsius to 20 degrees Celsius:
Where 
is the specific heat of water, that is the amount of heat that must be supplied per unit mass to raise its temperature in a unit.
Finally the 3 results are added:
Answer:
In the solid state particles are held closely together and vibrate slightly. They exist in a regular arrangement - there is no regular arrangement in the other states.
I don’t understand this launguage at all lol.I’m sorry.
Tectonic plate edges are not smooth. At transform boundaries, plates move against each other, but since the plates aren't smooth, lockups form. Stress is built up as both sides continue to steadily push against each other until there is sudden movement, where both plates quickly slide until they lock up again. This is what causes earthquakes.

I've also corrected the moon position relative to the penumbra. It's much more representative to the actual geometry but still not very accurate because of the vast distances between moon, earth and sun. Could not do much with the quarter moon with realism because of scales.
