Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate.
How do warm ocean currents affect the climate of the coastal areas?
Warm and cold ocean currents can affect the climate of coastal regions, but only when local winds blow in from the sea. Warm currents heat the air over the ocean and bring higher temperatures over land. Cold currents can lower air temperatures and can bring colder temperatures over land.
How does the ocean affect coastal climates?
The ocean influences weather patterns by distributing heat and moisture around the globe. … For example, because the ocean releases heat more slowly than land, coastal areas tend to be more temperate.
How do ocean currents affect coastal landscape systems?
(2) cold deep ocean currents carrying denser water away from the poles toward the equator. The ocean’s global circulation system plays a key role in distributing heat, regulating weather and climate, and cycling nutrients and gases around the earth.
How do ocean currents affect the climate of coastal regions explain in three points?
Ocean currents are caused by the uneven heating of the Earth surface. … Warm ocean currents increases the temperature of the near by coastal areas while cold ocean currents bring down the temperature. For example, the warm North Atlantic Drift keeps the temperature of Western Europe warm even during winters.
How can ocean currents affect the marine and coastal environment?
Currents are important in marine ecosystems because they redistribute water, heat, nutrients, and oxygen about the ocean. At the same time, currents inevitably sweep over and carry off living organisms.
How do ocean currents influence the climate and economic activities of the coastal regions?
Ocean currents influence the climate and economic activities of coastal regions in the following ways: Warm currents raise the temperature along the coast, while cold currents drop the temperature along the coast. … Winds blowing over warm currents result in a good amount of rainfall, as they get moisture-laden.
How do ocean currents influence climate in the coastal areas Class 7?
1. The ocean currents carry cold water from the polar regions to equatorial regions. 2. The winds blowing over warm currents are moisture-laden and, thus, cause rainfall in the coastal areas.
How does temperature affect ocean currents?
Water expands when it warms up – heat energy makes its molecules move around more and take up more space. … When water cools, it contracts and becomes denser. Temperature and salinity both affect the density of water, resulting in water moving up or down through the ocean layers and moving as currents around the ocean.
How do ocean currents affect the climate explain Class 11?
Winds passing over warm currents absorbs lot of moisture and cause heavy rainfall in coastal areas. On the other hand winds passing over long currents do not get any warm currents as such, they make the climate of coastal areas dry.
