What is geology? Goal: Tell the types of things that might be studies in geology. AB partners: Tell three things you think might be discussed in geology.

All of these are topics in geology except…..

Types of Rock Goal: Name the three categories of rock and tell how they form. AB partners: tell what you know about igneous, sedimentary and metamorphic rock.

Igneous Rock

Sedimentary Rock

Metamorphic Rock

Types of rocks

Weathering vs Erosion

Chemical Weathering

Erosion

Weathering or erosion?

Large Scale Erosion: Landslides

Sedimentary Rock Formation Examples

travertine

Dunn River Falls Chemical Sedimentary Rock Jamaica

Yellowstone National Park

Travertine Hot Springs Turkey

Shale - sedimentary

Igneous

Igneous Lake

What IS your metabolism? Your metabolism changes _______ to _________.

 Meaning to change shape  Changes with temperature and pressure, but remains solid  Usually takes place deep in the Earth

Schist

Slate

 Regional Metamorphism – pressure builds up in rocks that is deep within the Earth  Large pieces of the Earth’s crust collide and the rock is deformed and chemically changed by heat and pressure

Road-cut

Contact Metamorphism – heated by nearby magma Increased temperature changes the composition of the rock, minerals are changed into new minerals Hornfels is a fine-grained non-foliated metamorphic rock produced by contact metamorphism igh&fr=t

Non-Foliated – mineral grains are not arranged in plains or bands Marble is a non- foliated metamorphic rock that is produced from the metamorphism of limestone. It is composed primarily of calcium carbonate. Marble is a non- foliated metamorphic rock that is produced from the metamorphism of limestone. It is composed primarily of calcium carbonate.
