Answer:
Temperature changes can also contribute to mechanical weathering in a process called thermal stress. Changes in temperature cause rock to expand (with heat) and contract (with cold). As this happens over and over again, the structure of the rock weakens. Over time, it crumbles.

The correct answer is - the air.
The Namib Desert is one of the driest places on the planet and that is due to the cold and dry ocean currents alongside the southwestern part of Africa which are not providing the right conditions for precipitation to occur.
Even though there's no rain, because the Namib Desert is very hot, and the ocean currents very cold, the end result is mist that appears every morning, as well as dew.
The plants living in this desert have evolved in accordance to the conditions, so instead of being dependent on their roots for getting water, they get the majority of the water through their leafs and skin, directly from the air.

Explanation:
1. The continents fit together - this can be seen when we analyze in which direction they are moving and by reversing it we can see that they would fit almost perfectly together.
2. Fossils - many fossils were found scattered in some parts of the world and that would be impossible in a scenario where the continents didn't shift the way they did, or at all.
3. Rocks - magnetic mineral formation inside of rocks indicate that the continents were in another place during the formation of the rocks
