Where would you expect the ocean water to be less dense?

Where would you expect the ocean water to be less dense?

Cold, salty water sinks to the bottom of the ocean. The great ocean conveyor moves water around the globe. Cold, salty water is dense and sinks to the bottom of the ocean while warm water is less dense and remains on the surface.

Where would you find the least dense water Brainly?

The atlantic ocean is a worm ocean and the surface has the least dense water.

What type of water is least dense?

Water is densest at 3.98°C and is least dense at 0°C (freezing point). Water density changes with temperature and salinity. When water freezes at 0°C, a rigid open lattice (like a web) of hydrogen-bonded molecules is formed. It is this open structure that makes ice less dense than liquid water.

Where would you find the coldest saltiest waters in the oceans?

Deep zone (> 1,000 m): Water in this zone is the coldest, saltiest, and densest in the oceans (80% of ocean water).

What part of the ocean is the coldest?

Arctic Ocean

Which ocean is the hottest?

The Indian Ocean has the warmest temperatures of the world’s oceans.

  • Ocean water temperature is important to understand, as it affects global climate and marine ecosystems.
  • The Indian Ocean is the warmest in the world.
  • Ocean surface temperatures have risen by about 1.6°F over the past 100 years, due to global warming.

Can the ocean run out of oxygen?

If countries continue with a business-as-usual approach to emissions, the world’s oceans are expected to lose 3-4% of their oxygen by the year 2100. This is likely to be worse in the tropical regions of the world. Much of the loss is expected in the top 1,000m of the water column, which is richest in biodiversity.

How long before we run out of trees?

Study reveals the Earth is on track to run out of trees in 300 years. A team of researchers led by experts from the Yale School of Forestry and Environmental Studies recently completed what they claim to be the most comprehensive tree census ever.

How many trees does one person use in a year?

A human breathes about 9.5 tonnes of air in a year, but oxygen only makes up about 23 percent of that air, by mass, and we only extract a little over a third of the oxygen from each breath. That works out to a total of about 740kg of oxygen per year. Which is, very roughly, seven or eight trees’ worth.
