It rises upwards towards the surface of the earth because it is hotter and lighter than the surrounding rock. If it reaches the surface of the earth it will erupt as a volcano ...

Clastic rock
Clastic rocks are composed of fragments, or clasts, of pre-existing minerals and rock. A clast is a fragment of geological detritus, chunks and smaller grains of rock broken off other rocks by physical weathering. Geologists use the term clastic with reference to sedimentary rocks as well as to particles in sediment transport whether in suspension or as bed load, and in sediment deposits.
