Why are earth’s continental plates continually in motion

Geography
1 answer:
irakobra [83]4 years ago
6 0

Mantle convection.

Explanation:

The earth's continental plates are in continual motion as a result of mantle convection.

In the mantle, convection cells are set up that moves huge masses of earth materials from colder parts to hotter regions.

The earth crust is broken down into slabs which over rides the molten and weak asthenosphere.

The asthenosphere is hot and the materials here are in a molten state. The lithosphere sits on the asthenosphere and it is cold.

  1. Cold plates sinks inside the asthenosphere as molten magma rises.
  2. This movement of materials drives the over riding plate and causes them to move.
  3. Molten rocks are buoyant causing them to rise to the surface.

In hawaii the mongoose was brought to the islands to control the snake population it thrives and now the mongoose population is
frozen [14]
The mongooses are very effective in controlling the snake populations, as is the case in Hawaii, but the problem is that they represent an invasive species. As an invasive species, they disrupt the whole ecosystem on the islands, the local fauna can not cope with them because they do not have the defense mechanisms needed, nor can reproduce as fast, and also head to head are out competed, so the local fauna is becoming endangered and in time will probably get exterminated by the invasive mongooses.

Write an essay of 300 words including the following three parts: Describe the region of Central America, South America, and the
NikAS [45]

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.

The United States spends over $20 billion a year on space exploration through NASA. Do you think that this has been worth the co
julsineya [31]

Sunday, July 20, marked 45 years since the United States put the first two astronauts safely on the moon. The cost for the Mercury, Gemini and Apollo programs was more than $25 billion at the time more like $110 billion in today’s world. The ensuing U.S. space efforts have cost an additional $196 billion for the shuttle and $50 billion for the space station. NASA’s total inflation-adjusted costs have been more than $900 billion since its creation in 1958 through 2014 (more than $16 billion per year). Looking back, have we gotten our money’s worth from the investment?
