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...

silicates - minerals that contain silicon and oxygen and usually one or more other elements, are one of the largest groups of minerals oxides - compounds that have oxygen as their anion, t ut they exclude those with oxygen complexes such as carbonate, suphate, and silicate. have O2 as their anion, Ways rocks may form - Igneous: forms from magma that has either cooled slowly under ground or cooled quickly at the surface after a volcanic eruption Sedimentary rocks: formed when weathered frag...
