3. Weathering- Individual process that causes a physical or chemical change in socks and soil. Erosion- The surface of the earth is worn away by the action of water, glaciers, winds, waves, etc. Deposition- The dropping of material which has been picked up and transported by windm, water, or ice Sediment- Matter deposited by rocks by wind and water. Gravity- The pull or all matter from the atmosphere to the center of the earth. http://www.nature.nps.gov/geology/usgsnps/misc/gweaero.ht ml

4. Rock Cycle- A model that describes the formation break down and reformation of a rock as a Sedimentary, Igneous, and Metamorphic process. Igneous- A fire produced by volcanic action or intense heat. Sedimentary- Formed by the deposit of Sediment, as certain rocks. Metamorphic- Rocks that have morphed into another rock.

5. Law of Superposition- A key in natural history, based on observations of natural geology and dependent natural science. Geologic Time Scale- Provides a system of chronologic measurement relating strategraphy to time that is used by geologists. Fossil- Preserved plants and animals from long ago.

6.  Superposition is a key in natural history and observations made by geologic scientists over the course of many generations.  This Is pretty much a record book of everything that has happened over our history. Usually is recorded in all parts of the world ( See definition in rock cycle vocabulary called: LAW OF SUPERPOSITION)

7.  Definition- Provides a system of chronologic measurement relating strategraphy to time that is used by geologists.  The geological time scale is almost like the law of superposition in the way that they both keep record of geological events. The scale is also measured in many definitions of scientists recording different events.

8.  Weathering involves both chemical and physical events. Physical weathering is when erosion physically breaks down rocks into sediment and simpler form.  Chemical weathering is when things like water and rain break apart rocks. This example can be found in rivers and streams. When you pick up a rock, you might notice it can be very lose and wet. These conditions are helpful to the rock cycle and chemical weathering.

9.  Weathering involves physical breaking rocks into fragments without changing the chemical make up of the minerals within it. Erosion is when rocks particles move into different habitats like from a lake to a stream or from a stream to the ocean. Rocks can be eroded by wind water.

10.  The main agent of erosion is running water, the surface features of the water shed come directly from the action of running water both on the surface and underground.

11.  The Colorado river is believed to have formed the grand canyon. The Colorado river forms a canal that over millions of years, has eroded and weathered the rock. This is a perfect example for chemical weathering. Here is a picture to show you more!
