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

Explanation:

• Soft rocks are more prone to physical weathering as they can be easily eroded.
• Porous - surfaced rocks can absorb water, which can lead to processes like freeze - thaw weathering (when water freezes and expands in the pores).
• Rocks with minerals that dissolve easily (e.g., limestone with calcium carbonate that can dissolve in acidic water) are prone to chemical weathering.
• In a dry climate, there is less water (a major agent of both physical and chemical weathering). Less water means fewer freeze - thaw cycles (physical) and less chemical reaction (as many chemical weathering processes involve water as a reactant or medium).

Answer:

rocks that are in a dry climate
