How do rock types contribute to the rate of weathering? porous minerals weather faster. harder minerals break apart more easily. minerals that dissolve easily weather slower. permeable rocks have less chemical reactions.

The correct answer is that porous minerals weather faster.

The process of weathering alter and disintegrates the rocks and minerals closer to or at the surface of the Earth. This process shapes the Earth's surface. The three kinds of weathering comprise biological, mechanical, and chemical. Weathering dissociates apart and erodes rocks and minerals.  

The rocks are the symbols of strength and durability. The rocks are usually resilient to weathering. This confrontation relies on the mineral composition and mineral porosity. The physically soft or porous minerals are easily crushed and dissociated, while in case of harder minerals it is quite tough.
