Answer:
d. none of the above
Explanation:
The desert is a very frequent bioclimatic landscape on the earth's surface, characterized by its very low rainfall and low presence of fauna and flora, given the low humidity levels. Although the traditional image of the sandy desert refers to warm and equatorial climates, the truth is that they also count as deserts those located on the Arctic plateau or in the tundra.
The deserts are the product of different erosion processes, such as wind (given its high presence of winds that even form sandstorms) or the impact of solar radiation. The degree of intensity of these factors will depend on many desert characteristics, such as the type of sand formed or the nature of the soil.
Desert vegetation is, in principle, scarce, given the very low humidity margins. The one that exists has adapted to resist such adverse conditions, and it is usually xerophilous vegetation, with a predominance of spiny and resistant plants, such as the cactus, as well as weeds and, at best, small shrubs height.
Contrary to what is thought, there is a well-defined but very scarce desert ecosystem, although adapted to such an adverse environment and focused on the preservation of body moisture. Perhaps this is why reptiles (such as snakes), insects (ants, beetles) and arachnids (scorpions, spiders) abound.
Revealed by erosion and protected from moisture, in the deserts there are numerous mineral resources, such as oil basins (especially in the Middle East) or heavy metals.
Desert sand, also, is usually rich in calcareous elements and salts, so salt is often found in desert areas, such as in the Uyuni region of Bolivia. This type of desert drains the humidity of the environment even more, thus feeding back its aridity.
island arcs
rift valleys
deep-sea trenches
very tall mountain ranges
Answer: very tall mountain ranges
Explanation:When there is a collision between two continental plates, they become crunched up and then the rock folds at the boundary where it becomes lifted up and this leads to the formation of mountains and mountain ranges.
When collision occurs between two continental plates, both plates cannot be subducted because of their increased bouyancy. So when this collision occurs, features like subduction zone, trench and wedge do not occur. This type of collision occurs when the sea becomes narrower until both plates collide.
After the occurence of the collision, oceanic lithosphere breaks off and then sinks down into the mantle. The subduction zone then becomes inactive.
The two continents now welds together as they are being compressed together as time goes on.
The earth crust then becomes thickened by the under- thrusting of one continent under the other continent.
An example of this collision is the Himalayas where India collided with Asia.
B.sanctions
C.tariffs
D.free trade agreements
The correct answer is - B. sanctions.
The most typical tool used when some countries have disagreements and protest against each other, is the sanction. The sanctions, most often, are of economic nature, with limiting the export and import of goods of a particular country, and try to weaken it economically, so that it agrees to certain things, or stops doing certain things. Not all countries have the power to put sanctions, and they are usually practiced by the bigger political players on the global scene, like the USA for example, that has put sanctions in recent years over North Korea, Iran, Syria, and even Russia.

The deposition of a sequence of sedimentary rocks, the event is the first to occur to produce an angular unconformity is known as weathering.
The formation of sedimentary rocks involves the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. The mechanisms that lead to the accumulation of these particles are collectively referred to as sedimentation.
In contrast to metamorphic and igneous rocks, which are generated deep beneath the Earth, sedimentary rocks are formed on or around the surface of the planet. Erosion, weathering, dissolution, precipitation, and lithification are the main geological processes that result in the formation of sedimentary rocks.
The majority of the Earth's rocky surface is composed of sedimentary rocks, although these rocks only make up a very minor portion of the planet's crust.
Therefore weathering is the first to occur to produce an angular unconformity.
