Factors that affect the rate of weathering
www.wsfcs.k12.nc.usWeathering - the disintegration and decomposition of rock at or near the surface of the earth or simply the breaking of rocks. It affects the rocks in place and no transport is involved. This distinguishes weathering from erosion. Two Types of Weathering 1.
What is the difference between weathering and erosion?
www.doe.virginia.govChemical weathering involves chemical changes in the minerals of the rock, or on the surface of the rock, that make the rock change its shape or color. Carbon dioxide, oxygen, water, and acids may all cause chemical weathering. Mechanical weathering is the process of breaking a large rock into smaller pieces

Specifications for and Classification of Brick
www.gobrick.comWeathering Index Alternative is found in ASTM C 62, C 216 and C 1088. CSA A82 includes a freeze-thaw test as an alternative if the brick does not meet the physical property requirements. Other unit specifications include alternates as well. These are discussed in the Additional Requirements section.

Weathering, Erosion, and Mass-Wasting Processes
www.dnr.sc.govMechanical Weathering: Exfoliation Exfoliation is a mechanical weathering process whereby pressure in a rock is released along parallel alignments near the surface of the bedrock and layers or slabs of the rock along these alignments break off …
Weathering, Erosion & Deposition Flipbook
www.rcboe.orgWeathering is the wearing away or slow breaking apart of rock into smaller pieces. Plant roots, ice, wind, and water are all causes of weathering. Moving water in rivers cause rocks to rub together. Over time, these rocks get smaller and smoother. ’ Name: _____ Created By: Kristyn Copeland Plant roots growing in rocks
