As magma heats in the mantle, it becomes and begins to rise . This results in the magma traveling to the crust where it cools and becomes rock.

Answer 1

As magma heats in the mantle, it becomes less dense and begins to rise due to buoyancy. As the magma ascends through the Earth's crust, it can generate volcanic activity if it reaches the surface, resulting in volcanic eruptions. Alternatively, if it cools and solidifies beneath the surface, it forms intrusive igneous rock. This process is crucial in the rock cycle, where molten rock (magma) cools to become solid rock, contributing to the formation of various geological features. The cooling rate, composition, and pressure conditions during the solidification process influence the type of rock that forms, such as granite from slow cooling or basalt from rapid cooling at the surface.
