  1. Access Prior Knowledge Lesson 4: What is erosion? Opening Activity Open Science textbook to page 276. Open Science workbook to page 90A to review home learning. Open Science folder to review vocabulary words and outline for the chapter. Open Science journal and answer the following questions: 1. How are mechanical and chemical weathering the same and 
 different? Review Content Cards and Q-Cards in bin, sharing with partners quizzing each other 
quietly. Log in to clickers using student ID number. Be ready to review home learning when timer goes off. Don't forget to write your 
home learning in your 
agenda page 91A.

  2. Do you agree with the statement? 1 The processes of erosion and deposition are the same. Yes No

  3. Do you agree with the statement? 2 Ocean waves cause erosion on beaches. Yes No

  4. Do you agree with the statement? 3 Wind can cause both erosion and weathering. Yes No

  5. Do you agree with the statement? 4 Wind erosion only occurs in deserts. Yes No

  6. Erosion and Depsition Erosion is the movement of materials away from 
one place and deposition is the placing of the 
materials in a new place by wind, water or gravity. Gravity is the main force in erosion like a flowing 
river cutting into the rocks to form a canyon or a 
landslide pulling rocks and dirt downhill. Fast rivers carry more sediment. First paragraph pg. 276

  7. Wave Erosion Sand on the beach is created by waves which are a 
source of erosion and deposition. The constant action of waves is a major source of 
erosion along shorelines. Harbors and inlets form when some areas erode 
more quickly than others. Deltas are a place where heavy sediments are 
deposited when a river meets an ocean. Rocks are ground to sediment under moving glaciers. Roots of trees can be exposed because the flowing 
water removed the sand that used to cover them. First paragraph pg. 278

  8. Wind and Field Erosion The wind can move dust, dirt, or sand 
from one place to another. Wind erosion can cause problems on 
farms so farmers try to prevent wind 
erosion by planting trees along the edges 
of fields to block some of the wind. Large, loose deposits of sand are called 
sand dunes. Wind Erosion First paragraph pg. 280 Field Erosion First paragraph pg. 281
