True. Water has a lower melting point than most rocks, so when a rock is wet, the presence of water can lower the overall melting point of the rock.
Venezuela is farther from the equator than Iran true or false?
True. Venezuela is farther from the equator than Iran.
Does a wet rock generally melts at a lower temperature than a dry rock true or false?
True. A wet rock generally melts at a lower temperature than a dry rock because the presence of water in the rock lowers its melting point due to the water acting as a flux, reducing the energy required for melting.
