The figure below shows the process of subduction. What happens when the crustal plates move as shown in the figure? granting brainliest
Answers
Answer:
Upon contact with the continental plate, the oceanic plate, being denser, begins to sink into the asthenosphere. This sinking of the plate is called subduction. Once in the asthenosphere, the oceanic plate melts due to high temperatures. The melts thus formed come to the surface in the form of volcanic eruptions, forming a volcanic chain of subduction.
When two plates come in contact, a collision is created, which leads to earthquakes or sediment wrinkles, followed by their elevation and mountain formation.
Thus, the mountain ranges were formed: the American Cordillera and the Himalayan mountains.

In Iran are located the deserts:
Lut Desert is known as the is a large salt desert in the province of Kerman, Iran. It is one of the hottest places in the world, the temperature is about 70°C.Kavir Desert is also known as the Great Salt Desert located in the middle of the Iranian plateau. The climate is arid and the thermal amplitude can reach up to 70°C.Located in the Iranian province of Kerman, the Lut Desert is a sizable salt desert. With a temperature of nearly 70 °C, it is one of the hottest places on earth.
What are the two popular desert of Iran?The Great Salt Desert, also known as the Kavir Desert, is situated in the center of the Iranian plateau. The temperature can get to 70 °C, and the climate is dry.
The upshot is that the area provides some of the most stunning examples of aeolian yardang formations (massive corrugated ridges).
Due to intense surface evaporation and an almost entirely dry climate, the desert is characterized by a salt crust that covers dangerous salt marshes that resemble quicksand. Only the nearby mountain ranges contain settlements.
Therefore, There are significant stony deserts and dune areas there. The property serves as an outstanding illustration of current geological processes.

Write an essay of 300 words including the following three parts: Describe the region of Central America, South America, and the Caribbean's most pressing environmental issue. Explain why you think the issue you selected presents the biggest problem. Discuss steps that can be taken by individuals, businesses and/or governments to reduce this threat.
Answers
Answer:
Central America is a land bridge connecting the North and South American continents, with the Pacific Ocean to its west and the Caribbean Sea to its east. A central mountain chain dominates the interior from Mexico to Panama. The coastal plains of Central America have tropical and humid type A climates. In the highland interior, the climate changes with elevation. As one travels up the mountainsides, the temperature cools. Only Belize is located away from this interior mountain chain. Its rich soils and cooler climate have attracted more people to live in the mountainous regions than along the coast.
Hurricanes, tropical storms, earthquakes, and volcanic activity produce recurring environmental problems for Central America. In 1998, Hurricane Mitch swept through the region, devastating Nicaragua and El Salvador, which had already been devastated by civil wars in previous years.
The volcanic activity along the central mountain chain over time has provided rich volcanic soils in the mountain region, which has attracted people to work the land for agriculture. Central America has traditionally been a rural peripheral economic area in which most of the people have worked the land. Family size has been larger than average, and rural-to-urban shift dominates the migration patterns as the region urbanizes and industrializes. Natural disasters, poverty, large families, and a lack of economic opportunities have made life difficult in much of Central America.
High mountains ranges run the length of Central and South America. The Andes Mountains of South America are the longest mountain chain in the world, and a large section of this mountain range is in the tropics. Tropical regions usually have humid type A climates. What is significant in Latin America is that while the climate at the base of the Andes may be type A, the different zones of climate and corresponding human activity vary as one moves up the mountain in elevation. Mountains have different climates at the base than at the summit. Type H highland climates describe mountainous areas that exhibit different climate types at varying degrees of elevation.
Human activity varies with elevation, and the activities can be categorized into zones according to altitudinal zonation. Each zone has its own type of vegetation and agricultural activity suited to the climate found at that elevation. For every thousand-foot increase in elevation, temperature drops 3.5 ºF. In the tropical areas of Latin America, there are five established temperature-altitude zones. Elevation zones may vary depending on a particular location’s distance from the equator.
Amerindian groups dominated Central America before the European colonial powers arrived. The Maya are still prominent in the north and make up about half the population of Guatemala. Other Amerindian groups are encountered farther south, and many still speak their indigenous languages and hold to traditional cultural customs. People of European stock or upper-class mestizos now control political and economic power in Central America. Indigenous Amerindian groups find themselves on the lower rung of the socioeconomic ladder.
Answer:
One of the universal environmental issues that is also visible in the North America is air pollution. Climate change is caused by the greenhouse gas emissions that are linked to the production of CO2. Increased industrialization has contributed to the higher emissions that re warming the planet and causing further damage. Even Chinese pollution comes to the US over the Pacific Ocean, so we can say that this issue is on the Global level. With this comes water and soil pollution and we know that dirty water is the world’s biggest health risk. Today there is a new threat to clean water coming from EPA, where in order to get more natural oil and gas, we are endangering prestine natural resources. Soil contamination by toxic heavy metals also comes from the increased industrialization. Soil pollution will threaten food security. Solutions to air pollution are similar to those for climate change, though it’s important to make a efforts to drive less or to use electric cars like Tesla. Sustainable energy such as solar and wind power is also important, as that will decrease fossil fuel emissions.
