Answer:
D. tierra caliente, tierra templada, tierra fria, tierra helada.
Explanation:
The Latin American region has its own unique names for the elevation zones based on the climate. The lowest of them is the tierra caliente, characterized with lowlands and hills covered with dense tropical forests, and hot weather. The tierra caliente is the second, located between 1,000 and 2,000 meters, being still part of the tropical climate, but being cooler and more pleasant, which is why there are lot of big cities on this elevation. The tierra fria is located further up, up to 3,000 meters, and it is colder, dominated with grasslands, and the living conditions are not the best. The top elevation zone is the tierra helada, located in the highest parts of the Andes, being dominated by barren mountain slopes, strong winds, and cold climate.
A caldera is a large depression formed when a volcano erupts and collapses. During a volcanic eruption, magma present in the magma chamber underneath the volcano is expelled, often forcefully. When the magma chamber empties, the support that the magma had provided inside the chamber disappears.
This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice. As a consequence the surrounding seawater gets saltier, because when sea ice forms, the salt is left behind. As the seawater gets saltier, its density increases, and it starts to sink.
