Faye Moser MS Candidate in Earth Science University of North Carolina Charlotte fviscounccedu September 2016 GSA Dr Martha Cary Eppes Univ of N Carolina Charlotte Dr Brian Collins . 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. . Weathering: . The . process that breaks down rock and other substances at Earth’s surface.. Factors that contribute to weathering include:. Heat, cold, water. , ice, oxygen, and carbon dioxide. Erosion: . 10.4. Erosion. Water, in either gas, liquid, or solid form can change the surface of the earth, it can even carve . rock. !. Erosion is the . transportation. of broken down rock fragments (sediment) by water, glaciers, gravity, and wind. It can happen slowly or . 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. . Weathering . The process by which larger rocks are broken down into smaller and smaller rocks. Destructive force. Mechanical Weathering. The breaking down of larger rocks into smaller rocks WITHOUT changing the rocks’ minerals. 4 Types. Ice & Water. Abrasion. Plants & Animals. Exfoliation. 1.

King Saud University. WEATHERING PROCESSES. Weathering is the breakdown of rocks by . mechanical disintegration . and chemical decomposition.. What is Weathering?. The scenes of the world are continuously mutating. Sun, rain, frost, and wind are breaking down even the most solid of the rocks into smaller bits before they are taken away. This process is termed as weathering. . Chapters 14, 15, 16, 17, and 18. SES3. Students will explore the actions of water, wind, ice, and gravity that create landforms and systems of landforms (landscapes). . a. . Describe how surface water and groundwater act as the major agents of physical and chemical weathering. . Lesson 3 . Please Do Now!!!!! . -Looking at this picture what do we think caused this boulder to break apart???. -Please write down your thoughts. . -If you get the correct answer Miss. Swisher will give you a dollar. .
