Describe how a solid rock in the lower level of the crust could become a molten rock. PLS HELP I WILL MARK BRAINLIEST

The higher the pressure on anything, the hotter it will get.  The hotter a rock gets, the more possibility that it will have to melt.

So you're out the base of the crust, with any kilometers of crust above you, and that's a lot of pressure.  Then take into account that you have thousands of degrees of heat coming from the mantle-core boundary, and directly from radioactive decay within the mantle, which only adds to the temperature.

The net result is like melting a stick  of butter.  It's very easy to do without a lot of energy -- since Earth is a massive ball of thermal energy, then well... it's easy to do.

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.

explanation:

primary succession occurs in essentially lifeless areas regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. secondary succession occurs
