Ocean currents and masses are responsible for formation of sea ices at higher latitudes. The region of temperate climates will suffer from sea ice formation which affects coastal navigation leading to loss of economic activity. Warm currents prevent formation of sea ice even though the region is close to poles.Though the presence of water mass and ocean currents both impact coastal environments- ocean currents produce more dramatic and consistent impacts that touch the lives of people and animals than the water masses would have.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 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.
What is the difference between ocean current and water masses?
An ocean current flows for great distances which play a dominant role in determining the climate of many of Earth’s regions. Water mass, a body of ocean water with a distinctive narrow range of temperature and salinity and a particular density resulting from these two parameters.
What are effects of ocean currents?
- They result in rain. Warm currents lead to evaporation, which turns into the rain for the coastal areas. …
- They can also cause deserts. …
- They can destroy marine wildlife. …
- They help with the continuity of life. …
- They save up on time and costs. …
- They can result in deaths.
How is a water mass defined?
water mass in American English
a large body of oceanic water usually identified by a well-defined relationship between temperature and salinity or chemical content: usually a mixture of two or more such bodies, each having a specified temperature and salinity.
What is ocean currents Upsc?
Ocean currents are the continuous, predictable, directional movement of seawater driven by gravity, wind (Coriolis Effect), and water density. Ocean water moves in two directions: horizontally and vertically. Horizontal movements are referred to as currents, while vertical changes are called upwellings or downwellings.

Why some cold ocean currents are responsible for hot desert formation?
Cold ocean currents have a direct effect on desert formation in west coast regions of the tropical and subtropical continents. There is fog and most of the areas are arid due to desiccating effect (loss of moisture).
How does cryosphere affect global climate Drishti IAS?
In this way, cryosphere acts as an important cooling factor in the global climate system. Snow and ice act as an insulating layer over land and ocean surfaces, holding in heat and moisture that would otherwise escape into the atmosphere. This insulation, then, also acts to cool the global climate.
How does ocean current or bodies of water affect the climate?
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.
Why are ocean currents important to coastal regions?
Relate the role of ocean surface currents to climate. Background: Warm and cold ocean currents can affect the climate of an area along the coast if the winds blow in from the ocean. Warm ocean currents heat the air above the water and carry the warm air to the land, increasing the temperature of the coastal region.
How would a decrease in strength of deep ocean currents affect ocean life?
The evidence outlined in these studies is important for us to understand since the ocean’s circulation can directly affect the Earth’s atmosphere and biosphere. Weakening ocean currents can increase ocean acidification and make it difficult for marine life to survive.

What are the different types of water masses?
Water masses are also distinguished by their vertical position so that there are surface water masses, intermediate water masses and deep water masses.
Which water mass is the deepest water mass in the world’s oceans?
The most voluminous water mass is the Pacific Deep Water that fills most of the Pacific below the intermediate waters at about 1000 m.
What happens to a water mass when you increase the salinity?
The more salt there is dissolved in the water, the greater its salinity. When comparing two samples of water with the same volume, the water sample with higher salinity will have greater mass, and it will therefore be more dense.
How does water’s movement affect marine ecosystems?
Movement of water, in the form of waves, tides and currents, plays an import role in our oceans and impacts on all marine organisms. Wave action is one of the most significant environmental conditions affecting life in the sea.
What is ocean currents short answer?
Ocean currents are the continuous, predictable, directional movement of seawater driven by gravity, wind (Coriolis Effect), and water density. Ocean water moves in two directions: horizontally and vertically. Horizontal movements are referred to as currents, while vertical changes are called upwellings or downwellings.
How do ocean currents help in bringing rain in the land masses?
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.
What is the water mass on the Earth?
The total mass of Earth’s hydrosphere is about 1.4 × 1018 tonnes, which is about 0.023% of Earth’s total mass. At any given time, about 20 × 1012 tonnes of this is in the form of water vapor in the Earth’s atmosphere (for practical purposes, 1 cubic metre of water weighs 1 tonne).
Why do water masses retain their distinctive characteristics for long periods of time?
Why do individual water masses within the ocean retain distinctive physical properties for long periods of time? Because they flow separately and do not mix.
How does the cold and denser water masses sink to the depth of ocean?
How does the cold and denser water masses sink to the depths of ocean? Explanation: The cold and denser water masses formed by surface water sink to the depths of the ocean by thermohaline circulation. It is circulation of ocean water due to density gradient.
What is Atlantic meridional overturning circulation Upsc?
The Atlantic Meridional Overturning Circulation (AMOC) is a large system of ocean currents that carry warm water from the tropics northwards into the North Atlantic. The AMOC is an important component of the Earth’s climate system and is a result of both atmospheric and thermohaline drivers.

What is the general pattern of circulation of current in the Southern Hemisphere?
The result is that surface air in the Southern Hemisphere flows in an outward, counter-clockwise fashion from areas of high pressure and in an inward, clockwise manner to an area of low pressure. The surface wind in the Northern Hemisphere flows in the opposite direction.
Why is California cold now?
The water along the coast of California is cold for a couple of reasons. First, the California Current brings cold water from Alaska southward along the coast. And second, cold water from the deep ocean comes up to the surface through a process called upwelling.
