dense water floats

O

B. Increase in temperature - Ice melts and cools water - Cool,

dense water sinks

O

C. Increase in temperature - Ice melts and freshens water -

Freshwater floats over denser salty water

O

D. Decrease in temperature - Ice melts and freshens water -

Freshwater floats over denser salty water

Answers

Answer 1

Answer:

Answer:

Option A. Dense water floats.

Explanation:

Ocean circulation act as conveyor belt which transport warm water from the tropics towards poles from where cold water sinks to the deep ocean. It is also known as the thermohaline circulation because it is driven by salinity and temperature.

However, change in climate causing these ocean's thermohaline current to slow down because influx of cold and melting fresh water from the polar region is disrupting these circulation as influx of fresh water making the water less saline and less dense and hence it become harder to sink to deep ocean.

Answer 2

Answer:

Answer:

C. Increase in temperature - Ice melts and freshens water - Freshwater floats over denser salty water

Summarize: How are matter and substances related?

Answers

All substances are matter but all matters are not substance. Matter is generally a loose term used in respect to a substance. Matter and substance are sometimes used for the same context, this is certainly not correct. Various examples have already proved that a matter will not always be a substance depending on its physical nature, but a substance is always a matter.

Which best explains why the total mass of the product(s) would be less than thetotal weight of the reactant(s) after a chemical reaction?

Answers

The law of conservation of mass applies to all chemical reaction, so this means that there was equal mass before and after the reaction. However, if the mass has decreased, then it means there has been a loss of substance. The most common cause of this is the liberation of gases from a chemical reaction mixture, the mass of which is not measured by the scale.

An empty party balloon will float to the ceiling of a room once it is filled with helium.A. What does this tell you about the density of air in the room compared to the density of helium?

B. For the balloon to float in air, what two factors might have changed about the balloon?

Answer those two questions of you know the answer.

Answers

Helium is a gas composed of itself, were air is composed of Oxygen and Nitrogen making the air more dense than the helium making it float to find other gases

Two factors to change are Air pressure (due to the balloon moving ) and the helium making the balloon rise.

What hapeens to water once it reches the earth's surface

Answers

It either sinks into the ground or will eventually ending up in aquifers. It would also probably run of into creeks and rivers. Once its in the ground, its called "ground water".
Hope this helps!:)

It either soaks into the ground, or it's eventually going to end up in the acquifers. Also it runs off into the creeks and rivers eventually reaching the ocean. Once it goes into the ground the water becomes ground water.
