Question

Which rocks will likely weather the least? rocks that are soft rocks with a porous surface rocks that are in a dry climate rocks with minerals that dissolve easily

Answer 1

The rocks are in dry climate.

The relative permanence or “toughness” of the rock prone to weathering absolutely depends partially on sort of rock it is. This is because rock type is defined by the structure and relationship of the constituent metals, and complex metals vary in how they endure up to weathering.

Several types of rock, like granite, are very repellent to weathering. Moreover, Igneous rocks serve to heat slowly because it is difficult for water to penetrate into them.

Answer 2

Answer:

Option C, Rocks that are in a dry climate

Explanation:

Option A “rocks that are soft” can be weathered easily with the application of  temperature, pressure etc. Hence option A is incorrect

Option B” rocks with a porous surface rocks” have lot many fracture points and thus they break easily when acted upon by temperature, pressure or any chemical solution. Thus option B is incorrect

Option D “rocks with minerals that dissolve easily” can easily dissolve in water during heavy rains or when there is heavy water flow condition. Thus, option D is incorrect.  

Option C “rocks that are in a dry climate” have strong composition and thus they will provide maximum resistance to weathering.
