The breaking down of rocks that lie exposed to the weather.. Chapter 7 –Weathering and Erosion. Objectives:. Distinguish between weathering and erosion. Identify physical variables that cause mechanical weathering. Identify chemical variables that cause chemical weathering. Weathering. The breakdown do the materials of Earth’s crust into smaller pieces.. Physical Weathering. Process by which rocks are broken down into smaller pieces by external conditions.. Types of Physical 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.. 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 . 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 . 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. Weathering. The breaking down of rock into smaller pieces that remain next to each other. . Weathering forms sediments.. There are two types of weathering.. Mechanical (Physical) . Chemical. Mechanical Weathering. Weathering. is the break-up of rock due to exposure to the atmosphere.. Weathering. involves two processes that often work together to decompose or break down rocks.. Chemical and Mechanical. Weathering!. Predict how weathering might reshape surface features (topography). Weathering and Erosion. The top part of the lithosphere—the earth’s surface—changes as rocks are broken down to smaller pieces and carried away.. Weathering. Notes. Weathering. - The surface processes that break down rock into small pieces called sediment. . Two Types of Weathering. MECHANICAL WEATHERING. – . . Physical. processes that break rock into fragments with the . 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. .
