Chemical weathering

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

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

Weathering of rocks is important in the rock cycle and natural world. This talks about the various kinds of weathering and their role in shaping landscapes.

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.

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…

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

Students explore the effect of chemical erosion on statues and monuments by experimenting with chalk (to represent limestone) placed in liquids of different pH values. They also learn what engineers are doing to reduce the effects of acid rain.

Mechanical or physical weathering are processes that turn big particles of rock into smaller particles over time.

Chemical weather changes the composition of rock, usually through carbonation, hydration, hydrolysis or oxidation. Learn how these reactions happen.

Along the eastern shore, seaside attractions are being demolished and millions of homes are at risk as rising sea levels speed erosion

Climate change will exacerbate extreme flood events but may decrease the number of moderate floods.

The oxidizing chemicals hydroxyl and hydroperoxyl may clean the skies of harmful pollutants by reacting with them

Physical weathering occurs naturally over the course of time. Explore these physical weathering examples to uncover how this happens for different reasons.

There are two processes of soil formation i.e. physical disintegration & chemical decomposition of rocks. Formation of soil takes place without change in parent rock property in case of physical disintegration, while in case of chemical decomposition, properties of parent rock does take place.
