It would most likely be the last one. Erosion is effectively the process of natural forces breaking down rock or soil, which allows it to move from place to place with the aid of forces like wind or water. I would say the answer would be the first one, but it only says rock, while erosion can affect more than just rocks. Hope this helps.
Answer:
The orbit of the Earth
Explanation:
It is widely speculated that orbital mechanics were responsible for the period of lushness that the Sahara desert and Northern Africa lived only 6000 years ago. Due to the changes in the Earth's orbit around the Sun, it is thought that the monsoon effect (season variations in wind patterns that produce a heavy rainy season) was more pronounced across the northern latitudes and resulted in the Sahara being much wetter than it is today.
A community of men dedicated to living a holy life of prayer and manual labor is an accurate description of a monastery. The correct option among all the options that are given in the question is the last option or option "D". I hope that this is the answer you were looking for and hope that it comes to your help.
The answer is: HIGH POROSITY.
________________________________
(although low permeability can be associated with greater water retention. Permeability can be affected by particular size. For instance, larger particular have larger poles, so fluid (water) can pass through water quickly (higher permeability and less water retention). As such, smaller particles have smaller pores, so fluid (water) can pass through water LESS quickly (lower permeability and RETAINING MORE WATER.).

However, "high porosity" is the best choice.
Map making is the right answer...
