What Happens As You Descend From The Ocean Surface To The Deeper Layers Of The Ocean??

What happens as you descend from the ocean surface to the deeper layers of the ocean? The temperature decreases. The upper layer is heated by the sun but in all oceans the temperature drops to just above freezing below 1 000 meters.

Why does ocean water temperature vary with depth?

Cold salty water is dense and sinks to the bottom of the ocean while warm water is less dense and remains on the surface. … Water gets colder with depth because cold salty ocean water sinks to the bottom of the ocean basins below the less dense warmer water near the surface.

What is the term for the sharp decrease in temperature in the ocean with depth from the surface common in tropical and subtropical oceans?

In the thermocline temperature decreases rapidly from the mixed upper layer of the ocean (called the epipelagic zone) to much colder deep water in the thermocline (mesopelagic zone).

What has caused half of the world’s mangrove forests to be destroyed?

Shrimp aquaculture and land development are the two biggest reasons why half the world’s mangrove forests have been destroyed.

What happens when the ocean temperature increases?

Increases in sea surface temperature have led to an increase in the amount of atmospheric water vapor over the oceans. This water vapor feeds weather systems that produce precipitation increasing the risk of heavy rain and snow (see the Heavy Precipitation and Tropical Cyclone Activity indicators).

What happens to the temperature as the distance from the ocean increases?

As we know that water absorbs more sun heat than the land. So when the distance from the sea or ocean increases the temperature gradually decreases as the land cools down fast.

How does the temperature of ocean water change in the thermocline quizlet?

thermocline – is the layer where water temperature decreases rapidly with the depth. Much faster than the usual temperature drop. Below the layer the water temperatures drop at its usual rate.

How does the temperature of the Atlantic ocean change with latitude?

At high latitudes ocean waters receive less sunlight – the poles receive only 40 percent of the heat that the equator does. These variations in solar energy mean that the ocean surface can vary in temperature from a warm 30°C (86°F) in the tropics to a very cold -2°C (28°F) near the poles.

How does temperature affect the density of ocean water?

The density of water can also be affected by temperature. … The warmer the water the more space it takes up and the lower its density. When comparing two samples of water with the same salinity or mass the water sample with the higher temperature will have a greater volume and it will therefore be less dense.

What happens when mangroves are destroyed?

Losses of mangroves also release large amounts of carbon dioxide into the atmosphere arising from destruction of their biomass and the release of the large carbon stocks held in their soils. This affects all of us on the planet as it contributes to global warming further accelerating global climatic change.

What will happen if the mangrove ecosystem will be destroyed?

Destroying the mangroves contributes to changes in the coastlines such as coastal erosion. The rapid destruction of the mangrove forests for economic activities leads to the increase in the sediment load in the water that leads to the increase in siltation.

What threats do the mangroves face?

“In recent years the biggest regional threats to mangroves are the ever-increasing development of the tourism industry pollution from runoff of fertilizers and pesticides and improper disposal of wastes.

What is the surface of the ocean called?

Epipelagic Zone – The surface layer of the ocean is known as the epipelagic zone and extends from the surface to 200 meters (656 feet). It is also known as the sunlight zone because this is where most of the visible light exists.

Which factors affect the movement of ocean currents?

Oceanic currents are driven by three main factors:

The rise and fall of the tides. Tides create a current in the oceans which are strongest near the shore and in bays and estuaries along the coast. …
Wind. Winds drive currents that are at or near the ocean’s surface. …
Thermohaline circulation.

What happens when water salinity increases quizlet?

What happens when water’s salinity increases? Freezing point decreases.

Does the ocean temperature change?

The temperature of the ocean especially the surface varies from place to place and from season to season. … The variation in solar energy absorbed means that the ocean surface can vary in temperature from a warm 30°C in the tropics to a very cold -2°C near the poles.

How climate change is affecting the ocean?

As greenhouse gases trap more energy from the sun the oceans are absorbing more heat resulting in an increase in sea surface temperatures and rising sea level. … Increased ocean acidity makes it more difficult for certain organisms such as corals and shellfish to build their skeletons and shells.

What affects sea surface temperature?

The primary cause of rising SST levels worldwide is climate warming due to excessive amounts of greenhouse gases being released into the atmosphere. Heat from the warming atmosphere raises the temperature of the sea surface.

How does the change in ocean temperatures impact weather and life on land?

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.

Why does water temperature change slowly?

Water temperatures change slowly much slower than air temperatures because there is so much more mass in a particular volume of water to heat than in a similar volume of air and that mass of water can hold so much more heat than can air.

How does the ocean get warmer?

The main source of ocean heat is sunlight. … The heat energy eventually re-enters the rest of the Earth system by melting ice shelves evaporating water or directly reheating the atmosphere. Thus heat energy in the ocean can warm the planet for decades after it was absorbed.

How do temperature and salinity change as you descend from the ocean surface?

At 300-1000 meters in depth the temperature rapidly decreases. > 1000 meters in depth water temperature hovers around freezing. … Salinity and temperature affect seawater density if you increase salinity you increase density and if you increase temperature you increase density.

What happens to the water that is left behind after evaporation?

In the water cycle evaporation occurs when sunlight warms the surface of the water. … When that water evaporates the salt is left behind. The fresh-water vapor then condenses into clouds many of which drift over land. Precipitation from those clouds fills lakes rivers and streams with fresh water.

What happens as depth increases in an ocean?

Pressure increases with ocean depth.

This vehicle allows scientists to observe the deep sea under tremendous ocean pressure. … The deeper you go under the sea the greater the pressure of the water pushing down on you. For every 33 feet (10.06 meters) you go down the pressure increases by one atmosphere .

How does ocean temperature affect marine life?

The ocean absorbs most of the excess heat from greenhouse gas emissions leading to rising ocean temperatures. Increasing ocean temperatures affect marine species and ecosystems. Rising temperatures cause coral bleaching and the loss of breeding grounds for marine fishes and mammals.

How does the Atlantic ocean affect the climate?

How does the ocean affect the climate? The ocean absorbs heat from the Sun and ocean currents move that warm water all around the planet. … As Earth’s climate warms the water also warms melting sea ice. This warming could make the water less cold and less likely to sink.

How do temperatures vary with latitude?

Temperature is inversely proportional to latitude. … As latitude increases the temperature falls and vice versa. Generally around the world it gets warmer towards the equator and cooler towards the poles.

What happens to density values as you descend to the bottom of the ocean?

Ocean water gets more dense as temperature goes down. So the colder the water the more dense it is. … The temperature of the ocean decreases and decreases as you go to the bottom of the ocean. So the density of ocean water increases and increases as you go to the bottom of the ocean.

How does density change with depth in the ocean?

The water molecules pack together tighter as pressure increases –the pressure increase with depth due to the weight of the water above and causes the greatest density changes in seawater with depth (greater than the density changes due to temperature and salinity changes).

What influences density in the ocean and why?

The two main factors that affect density of ocean water are the temperature of the water and the salinity of the water. The density of ocean water continuously increases with decreasing temperature until the water freezes. … Temperature has a greater effect on the density of water than salinity does.

How will destruction of mangroves affect coastal regions?

“This has potentially devastating effects on biodiversity food security and the livelihoods of some of the most marginalised coastal communities in developing countries where more than 90 per cent of the world’s mangroves are found.” … The report recommends several measures to conserve and restore mangroves.

How does the removal of mangroves affect the population of marine life in the ocean?

At the same time the limited availability of food and the smaller habitat size associated with mangrove removal will result in weaker and more exposed fish populations vulnerable to increased rates of predation¹.

What are the effects of mangroves?

Human activity upland from mangroves may also impact water quality and runoff. These land and coastal activities result in increased erosion as well as the reduction of nursery areas supporting commercial and game fisheries.
