Quick Answer: How Do Ocean Currents Affect Weather And Climate?

How ocean currents affect the climate of India?

Ocean currents: Cold ocean currents flowing over a region will decrease the temperature of that area whereas warm currents will increase the temperature.

Relief features: Relief features are the barriers that block currents from entering the country.

High mountains act as barriers for cold or hot winds..

How does land water relationship influence climate and weather?

The land water influences the climate and weather by distributing heat, and storing solar radiation. Explanation: The water absorbs the radiation from the sun, especially in tropical waters located in equator. The areas of land also absorbs the light from the sun, and the atmosphere supports to keep the heat.

What are the 3 major ocean currents?

How do warm currents affect climate?

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. … Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.

Do landforms affect climate?

Water and landforms affect climate. High mountains are cooler than valleys. Oceans cool nearby land in the summer. Climate also affects plants and animals.

How do the ocean currents affect climate NASA?

The oceans influence climate by absorbing solar radiation and releasing heat needed to drive the atmospheric circulation, by releasing aerosols that influence cloud cover, by emitting most of the water that falls on land as rain, by absorbing carbon dioxide from the atmosphere and storing it for years to millions of …

As the horizontal currents are moving south or northwards, they carry with them cool or warm water over an extended distance. It is the displaced water that affects the air, by warming or cooling it, thereby transferring the same effect to the land surface over which it blows. This is how ocean currents affect climate.

What are the two main factors that affect deep ocean currents?

Deep ocean currents are density-driven and differ from surface currents in scale, speed, and energy. Water density is affected by the temperature, salinity (saltiness), and depth of the water. The colder and saltier the ocean water, the denser it is.

What nutrients and gases are transported by ocean currents?

Nowhere is the link between ocean circulation and productivity more evident than around Antarctica. There, strong currents pump nitrogen and phosphate up from the deep sea to fuel vast blooms of algae and other plants. These plankton are eaten by swarms of shrimp-like crustaceans called krill.

What is the strongest ocean current?

Antarctic Circumpolar CurrentThe Antarctic Circumpolar Current is the planet’s most powerful and arguably most important. It is the only one to flow clear around the globe without getting diverted by any landmass, sending up to 150 times the flow of all the world’s rivers clockwise around the frozen continent.

What are the two main categories of ocean currents?

There are two type of Ocean Currents:Surface Currents–Surface Circulation.Deep Water Currents–Thermohaline Circulation.Primary Forces–start the water moving.The primary forces are:Secondary Forces–influence where the currents flow.Solar heating cause water to expand.More items…

What happens if ocean currents stop?

If ocean currents were to stop, climate could change quite significantly, particularly in Europe and countries in the North Atlantic. In these countries, temperatures would drop, affecting humans as well as plants and animals. In turn, economies could also be affected, particularly those that involve agriculture.

What are the 5 major ocean currents?

There are five major gyres: the North and South Pacific Subtropical Gyres, the North and South Atlantic Subtropical Gyres, and the Indian Ocean Subtropical Gyre.

What type of climate is India?

India hosts two climatic subtypes- tropical monsoon climate, tropical wet and dry climate that fall under this group. 1) The most humid is the tropical wet climate—also known as tropical monsoon climate—that covers a strip of southwestern lowlands abutting the Malabar Coast, the Western Ghats, and southern Assam.

What is the main cause of ocean currents?

Winds, water density, and tides all drive ocean currents. Coastal and sea floor features influence their location, direction, and speed. Earth’s rotation results in the Coriolis effect which also influences ocean currents.

What causes ocean temperatures to rise?

The ocean absorbs vast quantities of heat as a result of increased concentrations of greenhouse gases in the atmosphere, mainly from fossil fuel consumption. … This is causing ocean temperatures to rise.

Can global warming trigger ice age?

Although loosely based on science, the deep-freeze scenario is wildly implausible and scientists queued up to pour cold water on it. “It is safe to say that global warming will not lead to the onset of a new ice age,” two distinguished climate scientists wrote in the journal Science.

How do ocean currents affect climate quizlet?

Currents affect climate by moving cold and warm water around the globe. In general, how do currents carry water? Currents carry warm water from the tropics toward the poles and bring cold water back toward the equator. … Since cold air holds less moisture than warm air, these currents bring cool, dry weather.
