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. 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.
The weathering of the sediment grains continues during erosion and transportation.
There are two different SAT practice exams for you to try, the answer key is also available. A spherically weathered boulder forms when the corners of an angular rock are broken down more quickly than the flat surfaces, forming rounded shapes.
These are the lecture notes that I used to create the PowerPoint slide shows. Screencast These are the video tutorials that were created using the PowerPoint slide shows we use in class.
For example, feldspar crystals in a volcanic tuff commonly weather to form new clay minerals. Erosion is the movement of the particles by ice, wind, or water. Differential weathering results when some rocks resist weathering more than other rocks, creating uneven rates of weathering and erosion.
This website was designed for my current students as a teaching tool. Most are between 15 and 30 minutes in length. Quartz, on the other hand, is very resistant to weathering. 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.
These screencasts vary in length. You can view them individually or as a slide show. Took these off the website, gonna have to actually do the workbook now! Weathering is the result of the interactions of air, water, and temperature on exposed rock surfaces and prepares the rock for erosion. Use the assignment sheet to help.
The most noticeable effect is the discoloration of the surface that results from the breakdown of minerals. We use it on a daily basis at school. The particles are then transported by that agent until they are deposited to form sedimentary deposits, which can be later eroded again or transformed into sedimentary rocks.
There are two kinds of weathering: The rock is chemically weathered when it reacts with rain, water, and the atmosphere to destroy chemical and mineralogical bonds and form new minerals.
Worksheets This is a PDF file that includes all of the worksheets that are required for this chapter. Chemical weathering weakens the bonds in rocks and makes them more vulnerable to decomposition and erosion.
Other minerals, such as calcite, dissolve. 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.More info: Ms.

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.
