Table of Contents Date Title Page 3-11-15 Deposition 62 Once you are finished with the Table of Contents, go to page 62 and add the title and date to the top of the page.

Deposit Deposit means… To put down in a specific place To put for safekeeping To make a payment

Deposition The laying down of rock, soil, organic matter, or other material on the surface of Earth In deposition, the larger pebbles settle to the bottom first. Then, smaller sand-sized particles sink. Finally, the smallest bits, called sand and clay, sink too.

Deposition Examples Example 1: Waves carry sand away from one shoreline and drop it to form a beach

Deposition Examples Example 2: Rivers deposit material where they flow into the ocean to form a delta Delta: a triangular area where a river divides into a larger body of water

Deposition Examples Example 3: Wind deposits silt and sand that forms a layer on top of the soil to create sand dunes

Question Explain how weathering, erosion, and deposition work together. Use the drawing to help you explain your thoughts.
