PPT-Erosion and Deposition Glaciers

Glaciers Geologists define a glacier as any large mass of ice that moves slowly over land There are two types of glaciers Continental glaciers Valley glaciers Continental Glaciers A continental glacier. Physical Weathering. Weathering. is the breakdown of rock or soil. . Physical . weathering occurs when natural forces, such as wind, running water, and moving ice, physically break up rock and soil into smaller particles. . The . surface. features of the Earth change as a result of observable physical and chemical processes . Weathering and Erosion. This is a monument . called Cleopatra’s . Needle. It was carved in Egypt around 1450B.C. The sides are carved with hieroglyphs, the writing of ancient Egypt. It stood in the dry, hot Egyptian desert for over 3000 years. During that time, the hieroglyphs remained distinct.. Earth’s Surface. Weathering, Erosion, and Deposition. from Ice, Water, and Wind. Weathering, Erosion, and Deposition. Weathering?. Erosion?. Deposition?. Wea. thering is the breaking down and . wear. J. Quigley. 4/2012. Water Shapes the Land. Water Shapes the Land. The Mississippi River is like a thousand dump trucks… every year it carries more than 300 million tons of sediment to the ocean! . This sediment is being washed away from the surface of the land and is called erosion.. Lesson 1. Water Erosion. How does Moving Water Cause Erosion?. Erosion is the process in which sediment that has been broken down through weathering is moved.. Agents of Erosion are:. Water. Wind. Glacial (ice). Scenario #1. Flood water pounds against a canyon wall and wears it down.. Weathering. Scenario #2. Rain washing soil away from a hillside. Erosion. Scenario #3. Layers of sediment forming at the bottom of the ocean. Contrast. the features left from different types of erosion.. Analyze. the impact of living and nonliving things on the processes of weathering and erosion.. Erosion and Deposition. Section 7.2. gravity: . another.. 2 . kinds:. 1) . Rill erosion. is the erosion by running water in small channels. , on the side of a slope.. 2) . Gully erosion. is when a rill channel evolves to become deep and wide.. Glacier – thick ice mass that forms over hundreds or thousands of years.. 15, 000 years ago > 30 % coverage - Today 10 % coverage. Valley Glaciers. Ice Sheets. Types of Glaciers. Valley Glaciers. Chapter 9 - Section 3, 4, 5, and 6. How Water Erodes. Most sediment washes or falls into a river as a result of mass movement and runoff. Other sediment erodes from the bottom or sides of the river. Streams carry sediment in several . What Is An . Ecoregion. ?. Ecoregion. - . a major ecosystem with distinctive geography, characteristic plants and animals, ecosystems, and receiving uniform solar radiation and moisture . Sometimes called an ecological region or bioregion. Finley’s 6. th. grade Science. Table of contents. How science works pg 1-2. Scientific Method pg 3-10. Science engineering and tech. pg 9-12. Chapter 1 review pg 13. Mineral Earth’s Jewels pg 15-20. - running water is the most effective agent of erosion. - gravity draws surface water downhill, which allows the water to erode soil and rock materials. - rivers also eventually leave their eroded materials behind, which we refer to as . The. . Erosion-Deposition. . Process. Constructive vs. Destructive. Constructive process build up features on Earth’s surface. Lave erupting from a volcano hardens and forms new land on the area where lava falls..
