It is harder to raise the temperature of water than it is to raise the temperature of a rock.
It takes 1 calorie of energy to raise the temperature of 1 gram of water by 1 degree C,
whereas it only takes 0.02 calorie to heat a gram of rock to that temperature.
Decreasing the pressure on rock will allow rock to melt at lower temperature. High pressures will raise the melting point of rock.
Coal is a sedimentary rock. However, harder forms of coal, because of exposure to elevated temperature and pressure, are metamorphic rock.
The height of the water will rise a level equal to the volume of the rock.
Water reduces the melting point of rock.
The same temperature as the rock in which it sits (the aquifer).
on rock outcroppings so that it is harder for predators to reach the youg and so that it is easier to teach the chicks to fly when the time comes.

The answer is Waterfalls because it is leaving harder rock for the water to spill over. Also a gorge, a sink hole, and a cave.
Water fall
Rapids
Am existing rock can be made harder by recrystallization or additional cementation.
