Bell Ringer 11.6.17 You have 5 minutes to work on the weathering and soil formation from worksheet from Friday. I will be collecting this on Wednesday for a grade!!! If you were not here on Friday please come up to the desk to get your sheet     

EQ: How does deposition change landforms? UNIT QUESTIONS: WHAT STORY DOES Our Land TELL? LEARNER PROFILE: Inquirer S6E5d. Ask questions to identify types of weathering, agents of erosion and transportation, and environments of deposition. EQ: How does deposition change landforms? HOMEWORK: Complete worksheet from Friday and Parts 1-3 of the Webquest.

Magic Monday The SUB on Friday stated that you were the best classes that she had ever sub for…. So today you get 10 minutes for magic Monday!! Enjoy

1- Definition 1- Foldable  Work Session Deposition – Water Deposition - Wind Deposition - Ice 1- Definition 1- Foldable 

Deposition – build up of land through the dropping off of sediments that are being carried by ice, wind, water or gravity Process of erosion stops: when the moving particles fall out of the transporting medium and settle on a surface What is Deposition?

Deposition - Wind When the wind slows down, the sediments are deposited The heaviest sediments are dropped first blown along the ground. Material is deposited when the wind changes direction or loses its strength. http://commons.wikimedia.org/wiki/File:Desert_Chihuahuan_Big_Bend.JPG

Deposition Effects Wind Sand dunes

Deposition - Water Running water enters a large, fairly still body of water and its speed decreases SPEED As the speed of the water decreases, the water's ability to carry sediment also decreases. Deposited in streams, rivers, and oceans: Running water deposits sediments where the slowing water can no longer move them. Largest particles are deposited near the shore. Increasingly smaller particles settle out farther from the shore where the water is calmer. http://commons.wikimedia.org/wiki/File:Enchanted_Rock,_stream.jpg

DEPOSITION NONLIVING CAUSES WATER -When the water slows down, the heaviest sediments are deposited first Older rivers have curves called meanders.

Examples sandbar delta beach

Beach: The zone above the water line at a shore of a body of water, marked by an accumulation of sand, stone, or gravel that has been deposited by the tide or waves. Barrier island: A sandbar disconnected from the land. They form due to longshore drift and protect shallow brackish bays or salt marshes behind them. They general form in areas of low shore gradient. Delta: As a river encounters a stagnant body of water, such as a lake or the ocean, the sediment load is deposited. The river will spread out across this delta into multiple channels, due to the meanders through this deposited sediment. Rivers with less sediment will form rounded fans (Nile), as the sea erodes its edges.

Deposition - Ice Glacial flows of ice – become slower when the ice begins melting – Deposits left by glaciers: Outwashes are deposits similar to those left by rivers. Large chunks of broken rock deposited at the base and sides of the glacier as it melts and recedes are called Moraines. When the glacial ice melts, smaller material is carried by the rivers. http://commons.wikimedia.org/wiki/File:Cavell_Glacier_with_Crevices_and_Annual_Rings.jpg
