Chemical weathering

I bet you don't know what weathering of rocks is. This explains weathering of rocks.

Chemical weathering occurs when rocks are weakened and broken down through chemical reactions. This process involves a chemical change, which actually alters the rock's or mineral’s chemical composition. Chemical weathering is more common in wet, humid areas than in dry ones, because moisture is an important component of many types of chemical weathering.

Weathering is the breaking down of rock into sediments (like sand, pebblies, silt, and clay) by the weather,either physically or chemically.

frost wedging - a type of disintegration in which jointed rock is forced apart by the expansion of water as it freezes in fractures.

The definition of weathering is the gradual destruction of rock under surface conditions. Think of the Grand Canyon or other rock formations.

We have been plugging away with our large landform unit. As we wait for the Foss Kits to show up I have been busy teaching weathering. As we move away from weathering onto erosion I wanted to show what we have done so far. Here is what we have done in science in the past two weeks (not including the GLAD component which I will make a separate post on later): Weathering Experiment: I took some different rocks from my yard (pebbles and decorative rocks bought at Home Depot) and placed them in…

Students explore the effect of chemical erosion on statues and monuments. They use chalk to see what happens when limestone is placed in liquids with different pH values. They also learn several engineering approaches to reduce the effects of acid rain.

Chemical weathering is a type of weathering caused by chemical reactions. Learn four examples of chemical weathering that affects rocks.
