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.

Are the oceans warming?

The International Panel on Climate Change (IPCC) Fifth Assessment Report estimates that the upper ocean (surface to 750 m deep) has warmed by 0.09 to 0.13 degrees C per decade over the past 40 years.

Does the ocean absorb carbon dioxide?

The ocean absorbs carbon dioxide from the atmosphere wherever air meets water. Wind causes waves and turbulence, giving more opportunity for the water to absorb the carbon dioxide.

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.

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.

What are the 6 factors that affect climate?

LOWERN is an acronym for 6 factors that affect climate.Latitude. It depends on how close or how far it is to the equator. … Ocean currents. Certain ocean currents have different temperatures. … Wind and air masses. Heated ground causes air to rise which results in lower air pressure. … Elevation. … Relief. … Nearness to water.

What is the main cause of ocean currents?

Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. … These currents move water masses through the deep ocean—taking nutrients, oxygen, and heat with them.

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 …

How do westerlies affect climate?

Westerlies are generally strongest in the winter hemisphere and at times when the pressure is lower over the poles. … The Westerlies play an important role in carrying the warm, equatorial waters and winds to the western coasts of continents, especially in the southern hemisphere because of its vast oceanic expanse.

What are the effects of ocean currents?

Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface.

Does Latitude Affect Climate?

There is a relationship between latitude and temperature around the world, as temperatures are typically warmer approaching the Equator and cooler approaching the Poles. There are variations, though, as other factors such as elevation, ocean currents, and precipitation affect climate patterns.

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…

Which ocean currents could be altered by climate change and what are the consequences?

If global warming results in increased rainfall in the North Atlantic, and the melting of glaciers and sea ice, the influx of warm freshwater onto the sea surface could block the formation of sea ice, disrupting the sinking of cold, salty water.

What are the 5 major ocean currents?

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

How does plastic in the ocean affect climate change?

As it does, sunlight and heat cause the plastic to release powerful greenhouse gases, leading to an alarming feedback loop. As our climate changes, the planet gets hotter, the plastic breaks down into more methane and ethylene, increasing the rate of climate change, and so perpetuating the cycle.

How do air currents affect climate?

Air Currents Prevailing winds bring air from one type of climate to another. For example, warm winds that travel over water tend to collect moisture as they travel; the water vapor in the air will condense as it moves into colder climates, which is why temperate coastal areas often receive heavy rainfall.

How does climate affect ocean currents?

Warming oceans alter currents Climate change impacts ocean temperatures as well as wind patterns — taken together, these can alter oceanic currents. … The impacts of changes in ocean currents on humanity could be severe, as currents play a major role in maintaining Earth’s climate.
