3.2 Do Now Imagine dropping a sugar cube into a cup of coffee and the same sugar cube into a cup of cold lemonade. In which cup do you predict the sugar cube will dissolve first? Why? Predict what you could do to make the sugar cube dissolve faster? List the three types of rock. Explain how each rock is created. Explain the difference between the two types of igneous rocks.

Weathering Unit 3 Day 2

Objective TSW explain the differences in chemical and physical weathering and how weathering rates are affected by a variety of factors using a Venn diagram. EQ: What factors influence the rate of weathering? What locations have the fastest weathering?

HOMEWORK Complete the half sheet weathering worksheet 3.2

How Does Surface Area affect the Rate of Weathering? Demo: Mints and water Create a hypothesis: Which mint (whole or broken) do you think will dissolve the quickest?

Biological Activity Activities of organisms of plants, burrowing animals, and humans.

Frost Wedging When water freezes and expands, it enlarges cracks in rocks.

What happens when you freeze a coke can? The liquid expands, and often times the can will bust!

Appalachian Mountains Southern Appalachians shared by the citizens of West Virginia, North and South Carolina, Tennessee and Georgia Falling rain, flowing streams and rivers, freezing and thawing that produced frost heaving and ice capable of shattering huge boulders and cracking apart walls of seemingly solid rock

Chemical Weathering Frost Wedging Biological Activity

Rate of Weathering Use the textbook page 131 to explain how rock characteristics and climate affect the rate of weathering. Draw this graphic organizer in your notes! Rock characteristics Climate Rate of Weathering
