Your friend brings you rocks with a thick layer of oxidation weathering, and no other visible signs of weathering. this is a clu
Vsevolod [243]
<span>A moist environment because physical weathering processes such as oxidation take place most quickly in the presence of water. There are three types of weathering, physical, chemical, and biological. For the physical weathering, there are two main types. Freeze-thaw cycles and exfoliation. Obviously the freeze-thaw cycles require water and the exfoliation generally happens through thermal expansion and contraction which doesn't require water. But since neither of these mechanisms were observed, that doesn't indicate if the area was wet or dry. Biological weathering is caused by plants or animals breaking down rocks via chemical (acid) or mechanical (root growth) means. Life generally indicates the presence of water, but since this form of weathering wasn't observed, we still don't have enough data. Chemical weathering is caused by rain water reacting with the rocks to form new minerals and salts. There are several types such as acidic rainwater dissolving part of the rock, and oxidation. With this in mind, let's take a look at the available options. A moist environment because there is a greater density of oxygen in the atmosphere in the presence of water. * Yes, we need a moist environment, but the density of oxygen is fairly constant world wide regardless of how moist or dry the environment is. So this is a bad choice. A moist environment because physical weathering processes such as oxidation take place most quickly in the presence of water. * Water speeds up chemical weathering of all types. So this is the correct choice. A dry environment because the increased albedo of deserts encourages physical weathering processes such as oxidation. * Yes, the increased albedo of deserts does speed up spalling, but oxidation is a CHEMICAL weathering process, not a PHYSICAL one. So this is a bad choice. A dry environment because in the absence of water oxidation is the dominant weathering process. * Water speeds up oxidation quite a bit. And since the observed oxidation is thick, there's been quite a bit of weathering. So this is a bad choice.</span>

In terms of energy resources, how do wealthier, developed nations compare
Luden [163]

Answer:

D. People who live in wealthier countries tend to consume more energy per person.

Explanation:

People in wealthy countries have access to many technologies such as phones, televisions, and house appliances like coffee makers. All of these use energy. Wealthy people also tend to have larger houses that require more electricity to light and heat/cool. People in developing countries do not have access to these technologies or large houses that consume large amounts of energy. Additionally, people in poverty are unable to afford the levels of energy that wealthy citizens can. For these reasons, wealthier countries consume more energy per person.
