This write-up throws irradiate upon the 5 main factors which affect the rate of weathering the rocks. The components are:- 1. Climate 2. Particle Size 3. Exposure 4. Mineral ingredient 5. Time.Factor # 1. Climate:
This is the most necessary factor influence weathering the rocks. The degree of weathering is dependent on the mean atmospheric problem prevailing in a region over a long duration of time.
There space two components that pat in weathering, viz. Temperature and Precipitation. Warm climates influence by chemistry weathering when cold climates affect by physics weathering (particularly by frost action). In either situation the weathering is much more pronounced with an ext moisture content.
You are watching: What are two factors that affect the rate of weathering
At greater temperatures chemistry reactions are likely to take place faster. Chemical reactions in most cases need water i beg your pardon is a reactant in hydration and also carbonation. Water is likewise the medium in i m sorry the reaction deserve to take place.
Biological activities are supported by hot moist climates. For circumstances burrowing humic mountain production throughout decomposition the plant matter are most likely in warm moist climates. In truth a warm moist climate gives the most ideal setting for rapid chemical weathering.
Physical weathering by frost action is most likely in cold climate where freeze and thaw occur alternately throughout the cold weather. In this case again precipitation is the key factor. In the absence of water ice cream cannot form and frost action is not possible. Thus an efficient frost activity occurs in the cold moist climate.Factor # 2. fragment Size:
Rate of chemical weathering is affected by size of rock particles. If the rock pieces room smaller, the weathering is faster. This is because if the absent pieces room smaller, the surface ar area exposed come weather activity is greater.Factor # 3. Exposure:
The extent of exposure i.e. The level to i beg your pardon the absent comes into contact with the agents of weather is crucial factor affect the weathering. In some situations, vegetation, soil, ice, etc. May cover a rock, thereby reducing the area exposed come weather action.
Such rocks so safeguarded weather slowly compared to rocks who surfaces room wholly exposed to weather. Steep of the region is also a element affecting weathering. Where the slopes space steep, loosened materials room displaced downhill one of two people by heaviness or by erosion result in consistent exposure the the fresh rock.Factor # 4. Mineral Composition:
We know, the chemical properties that a rock count on the mineral composition to a great extent. Mineral in a rock might readily react with acids, water or oxygen causing substantial weathering. For example limestone can acquire severely acted top top by even an extremely mildly acidic rainwater. Granite on the contrary mainly containing silica stays unaffected by together agents.
Physical weathering is likewise dependent top top mineral composition. Rocks which space soft room liable to be abraded much more readily than difficult rocks. The hard crystalline rocks are fairly compact through very little opening and also are really resistive come entry that water into them, and can because of this resist weathering.Factor # 5. Time:
The procedure of weathering is a time acquisition process.

The duration of time for which a rock is exposed to weather identify the degree of weathering. Very solid rocks, however strong they could be will certainly severely undergo weathering in numerous years.
