The world’s ocean is crucial to heating the planet. While land areas and the atmosphere absorb some sunlight, the majority of the sun’s radiation is absorbed by the ocean. Particularly in the tropical waters around the equator, the ocean acts a as massive, heat-retaining solar panel. Earth’s atmosphere also plays a part in this process, helping to retain heat that would otherwise quickly radiate into space after sunset.
The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe. When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds, often vast distances. In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area. Outside of Earth’s equatorial areas, weather patterns are driven largely by ocean currents. Currents are movements of ocean water in a continuous flow, created largely by surface winds but also partly by temperature and salinity gradients, Earth’s rotation, and tides (the gravitational effects of the sun and moon). Major current systems typically flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere, in circular patterns that often trace the coastlines. Ocean currents act much like a conveyer belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface. Without currents, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth’s land would be habitable.
Answer:
It allows for easier access to other South American countries for trade.
Explanation:
Smartest man I know is me, so therefore you should trust me.
There would be a much more severe caae of global warming if there is a sudden increase in greenshouses gases.
With greenhouse gasses such as carbon dioxide, the heat of the earth cannot be penentrated throught the atmosphere and will be trapped, the sunlight also cannot be reflected. This will cause the temperature of the earth’s surface to rise greatly.
The ice of the polar will melt resulting in the increase of water level globally. The increase of water level, when all the ice melt, will flood over some places in countires, even flooding the countries in low lying areas such as Japan.
It will also cause an imbalance in the ecosystem as some of the organisms require a certain temperature to facilitate its growth. With the high temperature, some types of organisms might not be able to survive while the organisms that favors high temperature will have a growth that distrupt the ecosystem. For example, coral reef will die if the temperature exceed 29°c.
