Weathering and Erosion Wind Water Ice Gravity

The breakdown do the materials of Earth’s crust into smaller pieces. Weathering The breakdown do the materials of Earth’s crust into smaller pieces. Weathering causes soil formation

Water causes weathering What evidence of weathering do you see in this picture?

Wind causes weathering Why wasn’t this mass of land weathered away? What evidence of weathering do you see in this picture?

Describe how ice causes weathering?

What evidence of erosion do you see in this picture? The process by which water, ice, wind or gravity moves fragments of rock and soil. What evidence of erosion do you see in this picture?

Erosion is Movement of Sediment! This process, known as Erosion, is gradually wearing down the surface of the earth. Erosion is the process by which weathered rock and soil (sediment) are moved  from one place to another. Erosion carves the Earth's surface creating canyons, gorges, and even beaches. What do you think has caused this rock to look this way?

The intensity of wind erosion is determined by: As the wind blows it picks up small particles of sand/sediment and blasts large rocks with the abrasive particles, cutting and shaping the rock. The intensity of wind erosion is determined by: Sum (amount) Speed Slope Surface

Wind Erosion Creates sand dunes Greatest impact in deserts Removes fertile topsoil

Water Causes Erosion runoff, rivers and, streams Creates MOST of the changes in the Earth's landscape!
