PPT-The Effect of Gravity on Erosion and Deposition

Agents of Weathering and Erosion Gravity not only influences the movement of water and ice but also causes rocks and soil to move downslope Mass Movement the movement of any material such as rock soil or snow downslope. Universal gravitational constant G667 x 10 11 Nm kg 2 2 EPS 122 Lecture 14 Gravity and isostasy Theory of gravity Gravitational potential Definition The gravitational potential V due to a point mass m at a distance r from m is the work done by th Gravity Pilates Tina Gravity Danielle MIND STUDIO MONDAY TUESDAY WEDNESDAY THURSDAY FRIDAY SATURDAY SUNDAY 8:00 Spartacus Boot Camp Rick 9:30 Barre Marla/Danielle Fusion (L1-2) Naomi Hatha Bust a move!. What is Erosion?. Erosion is defined as removal of rocks and soil by wind, water, ice and gravity.. Wind, water, ice and gravity are also known as the agents of erosion.. Weathering vs. Erosion . Chapter 4.1. Pages 118-127. Key Questions. How does moving water cause erosion?. What land features are formed by water erosion and deposition?. Moving water is the major agent of the erosion that has shaped Earth’s land surface.. 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.. Water Erosion. How Does Moving Water Cause Erosion?. Erosion by water begins with a splash of rain.. Some rainfall sinks into the ground.. Some evaporates or is taken up by plants.. The rest of the water runs off over the land surface.. Chapter 4.1. Pages 118-127. Key Questions. How does moving water cause erosion?. What land features are formed by water erosion and deposition?. The GREAT . BLUE. HOLE . p. 118. Where is it located?. Weathering. Weathering is the process that breaks down rock and other substances at the Earth’s surface. . Heat, cold, water, and ice all contribute to weathering.. Repeated freezing and thawing for example can crack rock apart into smaller pieces. . 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. erosion is the process by which the products of weathering are transported. agents of erosion are gravity, wind, glaciers, water, ocean waves, currents streams, groundwater. What is erosion?. What is Soil Erosion?. 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.
