Which is faster chemical weathering or mechanical weathering?
Chemical weathering tends to weaken rock, thereby making it easier to break. Likewise, mechanical weathering creates additional surface area that is prone to chemical attack. … Additionally, if temperatures are warm, then chemical weathering can proceed even faster. Then, mechanical weathering can move more quickly also.
What type of rock weathers the fastest?
Sedimentary rocks usually weather more easily. For example, limestone dissolves in weak acids like rainwater. Different types of sedimentary rocks can weather differently.
Which conditions lead to a slower rate of weathering?
The correct answer is option ‘high temperature’ as well as ‘low moisture levels’. This is because the high temperature will cause low humidity and if there is low humidity, then there will be less weathering. this is why, high temperature will help in decreasing the rate of weathering or slower the rate of weathering.
Why is chemical weathering faster in the tropics?
High temperatures and greater rainfall increase the rate of chemical weathering. … Rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions.
Which rock weathers most quickly most slowly?
Quartz is a mineral that weathers slowly. Rocks made up of minerals such as feldspar, calcite, and iron, weather more quickly. 4.
What climate is chemical weathering most rapid?
In general, chemical weathering would occur most rapidly in a cool, dry climate.
Does marble or granite Weather faster?
In an arid, temperate climate, mechanical weathering in the form of abrasion from windblown sand might be more prevalent than in a humid, temperate climate. This would lead to more mechanical weathering of marble than of granite because of the differences in the hardness of their constituent minerals.
