Answer:
Porosity is a characteristic of rocks that affects the rate of weathering.
Explanation:
The rocks of all types are weathering under the influence of natural factors/elements. The water, temperature, climate, humidity, precipitation, winds, ice, all have their say when it comes to weathering and each of them is dominant in some areas. It is not just them that affect the rate of erosion though, but also the type of rock and its characteristics.
One characteristic of the rocks that is very important for the rate of erosion is the porosity. The porosity is a characteristic that shows us how easy or hard the rocks let water or other liquids through them. If the coefficient is high, then the rate of erosion will be very high, but if the coefficient is low, then the rate of erosion will be also very low.
