question:
Movements of tectonic plates causes the creation of volcanoes. These volcanoes erupt. Volcanic mountains are formed from the eruption. Sometimes tectonic plates crash into one another or ride over one another. These plates sometimes fold and buckle, which forms Fold Mountains. Sometimes fault blocks are raised or tilted, and they form Block Mountains.
answer:
How are mountains formed?

question:
Fans blow air onto the evaporator's coils. The refrigerant within the coils absorbs the heat. The refrigerant changes from a liquid to a gas. The compressor compresses the gas, increasing the pressure. The hot, pressurized gas moves to the condenser. The gas condenses in the condenser and becomes a liquid again. Heat is radiated away from the condenser. The cooled liquid is returned to the evaporator.
answer:
How does an air conditioner work?
