What is it composed of: igneous rock, sedimentary, basalt, granite, siderite, conglomerate, quartizite, sandstone How resistant is it to erosion?

How much force do the waves impart on it and how frequently? I'm voting to close this question because it is too broad. Don't assume we know all geological formations worldwide. Add a link en.

Hydrolysis is the name of the chemical reaction between a chemical compound and water. When this reaction takes place, water dissolves ions from the mineral and carries them away.

These elements have undergone leaching. Through hydrolysis, a mineral such as potassium feldspar is leached of potassium and changed into a clay mineral. Carbon dioxide CO 2 combines with water as raindrops fall through the atmosphere. This makes a weak acid, called carbonic acid. Carbonic acid is a very common in nature where it works to dissolve rock. Pollutants, such as sulfur and nitrogen, from fossil fuel burning, create sulfuric and nitric acid. Sulfuric and nitric acids are the two main components of acid rain, which accelerate chemical weathering figure 7.

Acid rain is discussed in the Human Actions and the Atmosphere chapter. Figure 8. When iron rich minerals oxidize, they produce the familiar red color found in rust. Oxidation is a chemical reaction that takes place when oxygen reacts with another element.

Oxygen is very strongly chemically reactive. The most familiar type of oxidation is when iron reacts with oxygen to create rust figure 8. Minerals that are rich in iron break down as the iron oxidizes and forms new compounds. Iron oxide produces the red color in soils.

Now that you know what chemical weathering is, can you think of some other ways chemical weathering might occur? Chemical weathering can also be contributed to by plants and animals. As plant roots take in soluble ions as nutrients, certain elements are exchanged. Plant roots and bacterial decay use carbon dioxide in the process of respiration. Weathering rates depend on several factors. These include the composition of the rock and the minerals it contains as well as the climate of a region.

Figure 9. Different rock types weather at different rates. Certain types of rock are very resistant to weathering. Igneous rocks, especially intrusive igneous rocks such as granite, weather slowly because it is hard for water to penetrate them. Other types of rock, such as limestone, are easily weathered because they dissolve in weak acids. Rocks that resist weathering remain at the surface and form ridges or hills.

As the surrounding less resistant rocks were worn away, the resistant center of the volcano remained behind. Different minerals also weather at different rates. Some minerals in a rock might completely dissolve in water but the more resistant minerals remain. When a less resistant mineral dissolves, more resistant mineral grains are released from the rock. Climate is determined by the temperature of a region plus the amount of precipitation it receives. Climate is weather averaged over a long period of time.

Chemical weathering increases as:. So how do different climates influence weathering? A cold, dry climate will produce the lowest rate of weathering. A warm, wet climate will produce the highest rate of weathering.

The warmer a climate is, the more types of vegetation it will have and the greater the rate of biological weathering figure Does granite corrode? How does carbonic acid help to erode granite? How long does it take to erode a beach? Does limestone erode fast? What rock is Angel Falls made out of?
