Unit 7 notes Weathering What is it Disintegration and Decomposition of rocks Where does it happen At or near the surface of the Earth Weathering What does this process look like Weathering. Rose . AnnAgo. IV-6 . BEEd. WHITTLING . WIND . Bryce Canyon in Utah is a weathering wonder. Weathering and erosion have whittled away the rocks there for millions of years.. Today . huge hoodoos rise from the canyon floor. Hoodoos are rock pillars with shapes on their tops. They tower nearly 610 meters (2,000 feet) above the ground.. WEATHERING. Nature of weathering and erosion. Weathering. chemical and/or physical breakdown of a rock or mineral material. weathering involves specific processes acting on materials at or near the Earth’s surface. Earth’s Changing Surface . Earth is a constantly changing body affected by . natural forces. :. On the . Inside. :. Plate Tectonics . = moving of Earth’s Plates driven by . convection currents. Earthquakes & Volcanoes. 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: . formation of landforms. weathering and erosion. The process of weathering and erosion are the main forces behind landscape types. . However, they are not the only reason for a plain, plateau, or a mountain region to form. . 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. . Erosion. The carrying weathered rock from one location to another . Mechanical Weathering. Rock is physically broken down. Smaller pieces have same composition. Chemical Weathering. Rock is chemically broken down. Weathering and Erosion. Table of Contents. Section 1 . Weathering Processes. Section 2 . Rates of Weathering. Section 3 . Soil. Section 4 . Erosion. Chapter. 14.

The process of weathering and erosion are the main forces behind landscape types. . However, they are not the only reason for a plain, plateau, or a mountain region to form. . 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. .
