Learning Goal: We will learn the many ways which Earth's surface is built up and torn down. Benchmark Objective: SC.6.E.6.1 Describe and give examples of ways in which Earth's surface is built up and torn down by physical and chemical weathering, erosion, and deposition. DOK: Moderate

Learning Goal: We will learn the many ways which Earth's surface is built up and torn down. LEVEL 4 = I can…. Analyze the built up and tear down of the Earth’s surface. Predict the future appearance of the land over time. I can also do levels 3-2. LEVEL 3 = I can…. Compare and contrast physical weathering and chemical weathering. I can also do level 2. LEVEL 2 = I can…. Determine the cause and effect of weathering and erosion. LEVEL 1 = I can…. With some assistance/help, I can do some of level 2, otherwise, I am confused and need more time. LEVEL 0 = I am totally lost and confused. I really need help.

Weathering & Erosion What is Weathering? Weathering is a destructive force; it naturally breaks rocks down into sediment. Two basic types of weathering: 1) mechanical 2) chemical

Chemical Weathering Is the changing of a rock or a mineral’s chemical composition by natural forces. Rusting Reaction with acid Formation of clay Acid produced by plants (and animals) can cause biological weathering. For example:

What is Erosion? Erosion is the weathering of rock and the transportation of sediment. Sediments are broken-down pieces of rock from the weathering of larger rock. For example: Glacier Muddy river Clear mountain river Wind blown sand like in sand dunes

Erosion (transport) There are 5 main agents of erosion: *Running Water* Glaciers Wind Gravity Man Weathering has to happen before erosion. The rocks have to be broken into smaller sediments before they can be eroded away. Wind Erosion Glacier Mrs. Degl

Mechanical Weathering Mechanical weathering is the breaking down of rock into sediment by water, ice, or wind. Biological Weathering – Another form of mechanical weathering that break down of rocks into sediments by plants and animals. For example: Moving water Waves Freezing water Moving Ice (glaciers) Wind Plants Animals

It is the laying down of sediments (after erosion has occurred); What is Deposition? It is the laying down of sediments (after erosion has occurred); a constructive force. What happens to sediment after deposition? Burial Compaction Cementation Formation of new rock

Meandering (Curving) River/Stream Deposition happens on the inside of turns. Erosion happens on the outside of turns. Sediments are traveling the fastest in the center directly below the surface. Straight Flowing River/Stream Running Water
