A spherically weathered boulder forms when the corners of an angular rock are broken down more quickly than the flat surfaces, forming rounded shapes. The most noticeable effect is the discoloration of the surface that results from the breakdown of minerals.
Worksheets This is a PDF file that includes all of the worksheets that are required for this chapter. There are two different SAT practice exams for you to try, the answer key is also available.
These are the lecture notes that I used to create the PowerPoint slide shows. Erosion is the movement of the particles by ice, wind, or water.
Most of the time they are for the enter chapter; however, several chapters have more than one slide show or the slide show itself is broken into a couple different tutorials. The weathering of the sediment grains continues during erosion and transportation.
Other minerals, such as calcite, dissolve. Differential weathering results when some rocks resist weathering more than other rocks, creating uneven rates of weathering and erosion. Chemical weathering weakens the bonds in rocks and makes them more vulnerable to decomposition and erosion.
We use it on a daily basis at school. There are two kinds of weathering: I would recommend having these available while watching the PowerPoint or listening to the Screencast so you can handwrite more details in the margins, etc.
This website was designed for my current students as a teaching tool.
Took these off the website, gonna have to actually do the workbook now! Most are between 15 and 30 minutes in length. These screencasts vary in length. It is saved as a "PowerPoint Show" which means you do not have to have PowerPoint installed on your computer to view the slide show.
You can view them individually or as a slide show. Mechanical weathering is the process by which rocks are broken down into smaller pieces by external conditions, such as the freezing of water in cracks in the rock.Start studying Earth Science Topic Notes 6 (Weathering, Erosion, Deposition).

Sutliff teaches Earth Science, she enjoys nature and outdoor adventure activities, especially whitewater rafting and skiing. Regents Earth Science –Unit 9: Weathering, Erosion, and Deposition Weathering Weathering-the breakdown of rocks into soil Types of Weathering: 1.
Physical Weathering-any process that causes a rock to crack or break into pieces without changing it 2. Chemical Weathering-any process that causes rocks to breakdown by chemical.
Unit 5 Weathering, Erosion and Deposition The surface of the Earth changes daily. Rain, humans and planets all constantly change the surface of the Earth at different rates. Learn about the processes of weathering and erosion and how it influences our planet.
