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 sedimentary, igneous 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
Shale
Igneous
Igneous Lake
Igneous Rock Goals Be able to tell the relative chemical composition. (Does it have a high or low silica content.) Tell if the rock cooled quickly or slowly. Tell WHERE it formed. (Tell if it came from a violent or gentle eruption.)

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.
