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...

Igneous Rocks - ANSWER-These rocks were originally liquid, below the earth's crusts and are formed by lava and magma. Metamorphic Rocks - ANSWER-These types of rocks are formed by heat and pressure. Sedimentary Rocks - ANSWER-A river flows through a canyon and picks up a bunch of silt. That sediment and silt runs downstream and deposits where the river ends. When that material gets to the beach, it sits there. Over millions of years, _____ form. Earth's tilt on its axis. - ANSWER-Mr. ...

tidal hypothesis : Theory that the solar system started with a near collision of sun and large star. Few astronomers believe this theory. condensation hypothesis : solar system began with rotating clouds of dust and gas. Condensation happened in center to form sun, and smaller parts of clouds formed. More astronomers believe in this idea. Core : Outer core- liquid; inner core- solid. Very dense in center. Believed that core is 80% iron. Helps heat oceans. Mantle : Surrounds core. ...
