What role does the ocean play in regulating global climate?

The ocean plays a role in regulating the global climate by regulating water balance and temperature.

Compared with land, marine ecosystems regulate the global water cycle through evaporation, water vapor transport, precipitation and other links, promoting water balance; marine ecosystems can regulate temperature, and can regulate temperature by absorbing and releasing large amounts of heat. Global atmospheric temperature. The ocean accounts for 71% of the earth's surface and is the main supplier of atmospheric heat. At the same time, the heat capacity of seawater is much greater than that of air. The heat released when the temperature of 1 cubic centimeter of seawater decreases by 1°C.

Seawater is a transparent fluid, and solar radiation can be transmitted to deeper places, allowing a fairly thick layer of water to store heat. If the global 100-meter-thick surface seawater cools by 1°C, the heat released can warm the global atmosphere by 60°C. Therefore, the large amount of thermal energy accumulated in the ocean for a long time is a huge boiler. Through the transfer of energy, it can continuously affect weather and climate changes.

The importance of the ocean to the earth

1. The ocean provides the earth with many resources

It is said that there was no oxygen in the early days of the earth's formation, because cyanobacteria produced amazing Reproductive speed occurs in the ocean and produces a steady stream of oxygen through photosynthesis. Later, cyanobacteria covered the land. When the land had enough oxygen, life on the earth began to explode, and humans were born. The ocean provides a steady stream of oxygen to the earth and plays an important role in nurturing life on earth.

2. The ocean provides the earth with abundant mineral resources

The resources currently used by humans are not entirely mined on land. In fact, the ocean contains extremely rich mineral resources. , and there are still many seabed mineral resources to be developed. The ocean also brings rich biological resources to the earth and increases biodiversity. There are many more plants and animals in the ocean than we think.
