Of the two main sources of energy that drive the rock cycle - Earth’s internal heat and solar radiation – which is primarily responsible for each of the three types of rocks found on and within Earth? Explain your reasoning.
The three rock types are igneous, metamorphic, and sedimentary. Igneous rocks from the cooling and crystallizing of magma, metamorphic rocks are created from heat and pressure inside the Earth, and sedimentary rocks are formed from pressure. So, Earth’s internal heat is mostly responsible for the three rock types.
Internal heat is primarily responsible for each of the three types of rocks found on and within Earth. Internal heat is responsible for molten rock (1,200 to 2,200 °F), which is called lava if it erupts from a volcano. When it cools down, it becomes igneous rock.
