Story in the RocksBy: Riley Fanning, Maria Ezzell, Robbie Himebaugh

Rock Cycle/TypesThe Rock Cycle is the formation,

breakdown, and reformation of rocks.

The 3 types of rocks include Igneous, Sedimentary, and Metamorphic.

Igneous Rocks

A rock that forms after magma/lava cools.

Metamorphic Rocks

A rock that forms under a lot of pressure and heat.

Sedimentary Rocks

A rock that forms from compacted pieces of sediment.

WeatheringWeathering is two process

(chemical and physical) that often work in concert to decompose rocks.

Chemical Weathering – involves a chemical change in at least some of the minerals within a rock.

Physical Weathering – physically breaking rocks into fragments.

ErosionErosion is simple movement to a

slope due to gravity. (Mass Wasting)

Sheet Erosion – a type of soil erosion on sloping farmland, in which rain washes the top layer of soil off.

Sheet Erosion

Geologic Time ScaleThe Geologic Time Scale is a

chart that shows the eons, eras, epochs, and pivotal events, that happened in that time period.

FossilsA Fossil is an imprint that shows

bones, shells, animals etc. on rocks.

SuperpositionThe Law of Superposition is

the bottom layer of rocks are older than the top layer of rocks.
