The cycle begins with magma, fluid or mushy hot rock beneath the Earth's surface, which cools and crystallizes to form igneous rocks. These rocks can return to their roots as magma by 'subduction', being dragged back down through the crust to melt again. Alternatively, burial of igneous roc...
What do all igneous rocks have in common? What is the most common intrusive rock? What do granite and basalt have in common? What do all metamorphic rocks have in common? What is the most abundant element in the Earth's crust?

What is compaction in the rock cycle? How many active volcanoes are in Chile? How many separate mountain ranges make up the Rocky Mountains? What is extrusive igneous rock? How is halite formed? Which layer of the Earth contains the crust?
Slowly this sediment rock will get covered with other rocks and end up deep in the Earth's crust. The Rock Cycle When the pressure and heat get high enough, the sedimentary rock will metamorphose into a metamorphic rock and the cycle will start over again Note: rocks don't need to ...
There are two main types of crust: dense, young oceanic crust and older, lighter continental crust. The Earth's crust is an extremely thin layer of rock that makes up the outermost solid shell of our planet. In relative terms, it's thickness is like that of the skin of an apple. It...
rock cycle the series of processes in which rock forms, changes from one type to another, is destroyed, and forms again by geological processes uplift the rising of regions of the Earth's crust to higher elevations subsidence the sinking of regions of the Earth's crust to lower elevations ...
ROCKS AND THE ROCK CYCLE The earth’s crust is composed of many kinds of rocks, each of which is made up of one or more minerals. Rocks can be classified into three basic groups: igneous, sedimentary, and metamorphic. Igneous rocks are the most common rock type found in the earth’s ...
