Melting a. At what temperature does rock melt? __

The question is asking for the temperature at which rock melts. This is a geological phenomenon that occurs when rocks are subjected to high temperatures. The temperature at which a rock melts can vary greatly depending on the type of rock. For example, basalt, a common type of rock, melts at around 1,200 to 1,300 degrees Celsius. However, other types of rocks may melt at different temperatures. It's also important to note that the melting point of a rock can be influenced by other factors such as pressure and the presence of impurities.
