Question

How does hardness affect the rate of weathering in a rock?

Answer 1

Explanation:

Hardness of rocks makes weathering difficult and not easy to come by.

Weathering is the physical disintegration and chemical decomposition of rocks to form sediment and soils.

The agents of weathering are primarily the agents of denudation which are wind, rainfall, glacier, gravity and temperature.

• Most igneous and metamorphic rocks are usually termed hard rocks.
• Sedimentary rocks typically falls into the category of soft rocks.
• Hard rocks are more compact and have their crystals woven into one another.
• It takes a longer time for them to get weathered.
• Soft rocks are often times bounded by cements.
• The cements are chemical substances that easily reacts and can cause they to be easily broken down.

Therefore, the harder a rock is, the more time it takes for it to be disintegrated.
