Rocks: Earth Science Latest Update with Verified Solutions What does the term "rock cycle" refer to? The rock cycle describes a sequence of geological processes that transform rocks from one type to another over time, both on the Earth's surface and beneath it. How is magma different from lava? Magma refers to molten rock that solidifies into igneous rock beneath the Earth's surface, while lava is magma that reaches the surface and solidifies there. What is the process of w...
