Unit 1 soil changes Lesson 6- Chemical weathering

What is the difference between weathering and erosion?

Weathering is the physical or chemical breakdown of rock. Erosion is the removal of weathered pieces of rock to another place

What is the difference between mechanical and chemical weathering?

Mechanical weathering is the physical breakdown of rock into smaller pieces. Chemical weathering is the breakdown of rock by chemical processes.

How do water, air, and organisms cause chemical weathering?

Water, air, and chemicals released by organisms cause chemical weathering of rocks when they dissolve the minerals in a rock. They can also cause chemical weathering by reacting chemically with the minerals in the rock to form new substances.

How do mechanical and chemical weathering work together to speed up the weathering process?

Mechanical weathering breaks rocks down into smaller pieces. This gives the rock a larger surface area for chemical reactions to take place. Chemical weathering weakens rock, making it easier for it to be broken down by mechanical weathering.

erosion

the process in which wind, water, ice, or other things move pieces of rock and soil over Earth's surface (related word: erode)

dissolution

to add a solid material to a liquid in such a way that its particles completely disperse into the liquid, usually becoming invisible within the liquid (related word: dissolution)

oxidation

3. a chemical reaction in which oxygen combines with another substance; for example, when metal rusts

limestone

a kind of sedimentary rock: Some kinds of limestone are made from ancient sea shells.

chemical weathering

occurs when chemical reactions cause permanent changes to rocks and other physical features

mechanical weatherign

is the physical breakdown of rock material

cave

a large underground chamber, typically of natural origin, in a hillside, or cliff

cavern

a cave, or a chamber in a cave

sinkhole

. a cavity in the ground in limestone bedrock, caused by water erosion and proving a route for surface water to disappear underground

groundwater

water held underground in the soil or in pores and crevices in rock

weatherign

the physical or chemical breakdown of rock
