How do marine scientists use models to study the ocean?

Biology
1 answer:
kaheart [24]3 years ago

A scientific model is a representation of something in the natural world. Models allow scientists, such as marine biologists, to study things that may be too large, too small, or in some way too difficult to study.

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>

The Ring of Fire is a region of tectonic activity. This means that it is an area where __________ are especially common.
Andreas93 [3]
<h2>Answer:</h2>

<u>a. Earth quakes</u> are common.

<h2>Explanation:</h2>

"Ring of Fire" is a significant region in the bowl of Pacific Ocean where numerous earthquakes and volcanic ejections happen. In an enormous 40,000 km horseshoe shape, it is related to an about nonstop arrangement of maritime channels, volcanic circular segments, and volcanic belts and plate developments. It has 452 volcanoes.

About 90% of the world's tremors and about 81% of the world's biggest seismic tremors happen along the "Ring of Fire". The Ring of Fire is an immediate aftereffect of plate tectonics: the development and impacts of lithospheric plates, particularly subduction in the northern segment.
