They are formed in nature, solids, non-living, and have a crystalline structure.

A naturally occurring solid mixture of one or more minerals, or organic matter.

Pieces of the lithosphere that move around on top of the asthenosphere.

The hypothesis created by Alfred Wegener that stated that the continents once formed a single landmass, broke up, and drifted to their present locations.

Mountains, volcanoes, and trenches with subduction zones.

*Special Properties

The continual process by which new rock forms old rock material.

* It is the thinnest layer and outer layer of the Earth.
* It is made from minerals and igneous, sedimentary, and metamorphic rocks.
* Contains less dense compounds.
* There are two types of crusts: the Continental crust and the Oceanic crust. The Oceanic

Pangaea

Mid ocean ridges and volcanoes.

Fluorite and Apatite

First,you have an Igneous rock.Next,you apply heat and pressure to form a Metamorphic rock.

* The layer between the crust and the core.
* It is the thickest layer (2,900 km).
* It contains most of the Earth's mass.
* We haven't gotten there yet but we only know about it because of underwater volcanoes.
* Is very hot and dense.
* Contains lithosp

It is the process by which new oceanic lithosphere forms as magma , rises toward the surface, and solidifies.

A fault line.

A fine grained Igneous rock has little to no crystals because it cools outside of a volcano which cools very quickly.A coarse grained Igneous rock has a lot of crystals because it cools inside of a volcano which cools very slowly.

* Liquid layer of core.
* Made from melted, liquid iron and nickel
* Can be studied by indirect means.

Near mid ocean ridges because sea floor spreading occurs at a mid ocean ridge and sea floor spreading produces new ocean floor at the mid ocean ridge.

Rocks are able to move from the top of the mantle to the bottom through the process of convection currents because rocks at the bottom of the mantle, heat up, become less dense, and rise to the top of the mantle. Then, it will cool, become more dense, and

The key features of a Sedimentary rock is it's Strata. In a clastic sedimentary rock, it's because of their grain size and fragments of rocks cemented together.In a organic Sedimentary rock it is the remains of plant and animal fossils.

* Solid, dense, and the very center of the Earth.
* Made from solid iron and nickel.
* Contains densest compounds.
* Can be studied by indirect means.
* The temperature can reach up to 9,000 degrees Fahrenheit.
* Is solid because the temperatures are so g

Near the trenches because as the new ocean floor forms, the older ocean floor gets pushed away from the mid ocean ridges towards the trenches.

The process by which the shape of a rock changes because of stress.
