Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. A similar process, weathering, breaks down or dissolves rock, but does not involve movement.

For example, take rain on a frigid day. The water pools in cracks and crevices. Then, at night, the temperature drops and the water expands as it turns to ice, splitting the rock like a sledgehammer to a wedge. The next day, under the beating sun, the ice melts and trickles the cracked fragments away.

Mechanical weathering, also called physical weathering and disaggregation, causes rocks to crumble. Water, in either liquid or solid form, is often a key agent of mechanical weathering. For instance, liquid water can seep into cracks and crevices in rock. If temperatures drop low enough, the water will freeze.

Wind, rain and waves can all cause weathering. The wind can blow tiny grains of sand against a rock. These wear the rock away and weather it. Rain and waves lashing against a rock can also wear it away over long periods of time.

Oxidation and hydration: Oxidation produces iron oxide minerals (hematite and limonite) in well aerated soils, usually in the presence of water. Pyroxene, amphibole, magnetite, pyrite, and olivine are most susceptible to oxidation because they have high iron content.

Answer: Oxidation is the reaction of rock minerals with oxygen, thus changing the mineral composition of the rock. Carbonation is the process of rock minerals reacting with carbonic acid. Carbonic acid is formed when water combines with carbon dioxide.

Answer. Carbonation is a chemical process where the main reactant is the carbon dioxide gas which mainly produces different carbon substances such as carbonates, bicarbonates and carbonic acids. Solution is a mixture of two different substances which are able to completely or partially mix with each other.

As nouns the difference between solution and hydration is that solution is a homogeneous mixture, which may be liquid, gas or solid, formed by dissolving one or more substances while hydration is (chemistry) the incorporation of water molecules into a complex with those of another compound.

A form of weathering where the grains of a rock become loosened and fall out, to leave a pitted, uneven surface.

1 : consisting of or appearing to consist of granules : grainy. 2 : finely detailed granular reports.

While Granular disintegration process of physical or mechanical weathering due to repeated heat and cooling because of temperature change. As a result of alternative expansion and contraction of minerals in rocks causes the rock to break down into small pieces.

Example in the deserts. Granular Disintegration: When the agents of weathering, reduce rocks made up of different minerals to small pieces and fragments, it is called granular disintegration. Exfoliation: The changes in temperature may create fissures or cracks in rocks.

In the first stage the rocks experience granular disintegration due to the widening of grain boundary microcracks and loosening of the rock structure. SEM and microprobe data indicate that during this stage chemical alteration of biotite and feldspars is limited and occurs mainly on grain margins and along microcracks.

A form of weathering where the grains of a rock become slackened and fall out due to repeated heating and cooling as a result of temperature changes. This kind of weathering It takes place in cold regions and places located at high altitudes.

Disintegration involves the breakdown of rock into its constituent minerals or particles with no decay of any rock-forming minerals. Rock alteration usually involves chemical weathering in which the mineral composition of the rock is changed, reorganized, or redistributed.

Physical weathering does disintegration of rock without chemical reaction and the chemical weathering does change in chemical compounds within rock….Weathering :

• Weathering is the breaking of rocks by elements of atmosphere.
• It involves no motion.
• Temperature, frost, wind, plants and animals are its main agents.

– Internal tension results and the rock disintegrates into grains over time. It takes place in cold regions and locations situated at high altitudes. – The outer layer creates cracks and then peels off with time and parts of rocks fall under gravity.

2 Answers. Mountains and rock do decompose or weather into sediment. A basic rock cycle overview shows the possible pathways between all three rock types (igneous, metamorphic, and sedimentary) how one type can be transformed into another. After a rock is weathered into sediment, that sediment can become a rock again.

Disintegration of rocks by weathering processes produces three types of weathering products: detrital material from the rock and vegetation; solutes from the dissolution of minerals and organic matter; and new minerals from chemical reactions between solutes and minerals.
