Most scientists infer that a major factor in the increased rate of melting of Earth's glaciers is an increase in carbon dioxide in Earth's atmosphere.
Glaciers begin to form when snow remains in the same area for a long time and snow accumulates to transform into ice. Melting is a process that causes the substance to change from solid to water.
There are some major causes of the melting of Earth's glaciers, carbon dioxide, and greenhouse gases emission increased temperature, burning the fossils fuel, oil and gas drilling, deforestation, ice-breaking ships, extreme flooding, etc.
Therefore the correct option is D.

Answer:
D) an increase in carbon dioxide in Earth's atmosphere.
Explanation:
The primary explanation proposed by most scientists is that a major factor in the increase rate of glacial melting and the decrease in the overall length of most glaciers is the increased levels of carbon dioxide (greenhouse gas: Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities).
B. Transandes Mountains
C. Rocky Mountains
D. Himalayan Mountains
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.
