ANATOMY

Detailed explanation-1: -The rock cycle is driven by two forces: (1) Earth’s internal heat engine, which moves material around in the core and the mantle and leads to slow but significant changes within the crust, and (2) the hydrological cycle, which is the movement of water, ice, and air at the surface, and is powered by the sun.

Detailed explanation-2: -The two main factors in the Earth’s mantle that contribute to the rock cycle are convection and tectonic forces.

Detailed explanation-3: -Several processes can turn one type of rock into another type of rock. The key processes of the rock cycle are crystallization, erosion and sedimentation, and metamorphism.

Detailed explanation-4: -The existing rock must be exposed to high heat, high pressure, or to a hot, mineral-rich fluid. Usually, all three of these circumstances are met. These conditions are most often found either deep in Earth’s crust or at plate boundaries where tectonic plates collide.

Detailed explanation-5: -Answer and Explanation: In the rock cycle, heat and pressure are metamorphic forces applied to existing rocks to transform them into metamorphic rocks. Metamorphic forces do not melt the rock as they would when forming an igneous rock. Instead, the heat and pressure are much less intense.
