2.) By their longitude

Hope I helped! :D

Answer 2

Answer:

B) mechanical weathering

C) by their longitude

Explanation:

• Mechanical weathering refers to the process of breaking large rocks into smaller ones. There are several potential causes for this. Temperature contributes to it, as changes in temperature cause various materials to expand and contract. The roots of plants and burrowing animals can also transform rocks. Finally, this can happen due to the freeze-thaw cycle.

• Longitude would be the measure that would allow us to distinguish between these two points in the map. Longitude is measured by imaginary lines that run around the Earth vertically, and meet at the Poles. Therefore, these lines allow us to measure how East or West a point is from the prime meridian, which runs through Greenwich, England.
