Heating a liquid (or any substance for that matter) causes it to expand, decreasing its density. In cooler liquids, the particles are a little closer to each other, so the liq. is more dense. Dense substances sink to the bottom (you could think of them as being a little heavier due to their higher density)

Is Venus too cold for water to exist on its surface?
No. Venus is far too hot for water to exist on its surface.
Describe the two steps of upwelling?
Upwelling occurs when wind pushes surface ocean water away from the coastline, causing deeper, colder, nutrient-rich water to rise and replace it. This brings nutrients to the surface, fueling the growth of phytoplankton and supporting a productive marine ecosystem.
Does cold water rise or fall in deep ocean currents?
Water, when cold, would sink as would other substances as the molecules in in become less active. The unique exception is when water freezes it rises, due to the molecules lining up to form crystal structures allowing spaces and thus making it act as a floatation device. Without this extraordinary property of water, life, as we know it, would not exist.
What is the phenomenon of cold deep current moving toward the equator?
The phenomenon you are referring to is called "cold deep water upwelling." It occurs when cold, nutrient-rich water from deep ocean currents rises towards the surface as it moves towards the equator. This process plays a crucial role in maintaining oceanic ecosystems by transporting nutrients and supporting marine life.
It is to hot for liquid water to exist?
It is too cold for liquid water to exist on the surface
When upwelling takes place cold water from the deep ocean does what?
Rises to the surface.
Why is the surface of water in a pond cool even on a hot day?
The sun heats the water surface. Warm water has a lighter density than cold water so the warmer water floats on the surface of the colder water.
Why the bottom of a pond is cooler than the top during a hot summer?
The sun heats the water surface. Warm water has a lighter density than cold water so the warmer water floats on the surface of the colder water.
Why bottom of the pond is cooler than the top during a hot summer day?
The sun heats the water surface. Warm water has a lighter density than cold water so the warmer water floats on the surface of the colder water.
How can water float on water?
freeze water as ice cubes then put it on water and it floats Liquid fresh water floats on salt water Warm water floats on cold water (water's greatest density is when it is 4 degrees Celsius).
When warm and cold water mix what happens to the warm water?
the warm water floats
Does hot water rise and cold water sink?
HOT rises COLD sinks
Hypothesis for why soda can floats in cold water?
because a soda can is full of air. Air is lighter than water, and is therefore boyant and the can floats.
What is a process in which cold nutrientrich water from the deep ocean rises to the surface and replaces warm surface water?
Nothing very exciting happens because as the cold water would rise it would push the warm water down. This would cause the cold water to heat up and the warm water to cool off. This creates a cycle of cooling and warming.
When cold water is mixed with hot water the hot air rises up why?
The reason for this is convection, when the temperature rises the liquid (in this case water) expands, causing it to rise above the cold water which is denser due to the lower temperature. So the hot water rises and the cold water sinks, making a convection current.
Why do the best fishing grounds develop at the meeting places of warm and cold ocean currents?
Cold water is rich in oxygen and plankton, krill, etc. Warm water rises and brings the food carried in the cold water towards the surface, and so feeds the fish shoals.
How does convection transfer?
Think of a pot of boiling water. The burner makes the heat, the heat rises, and the cold water replaces it, then the cold water gets hotter and rises. It's a cycle
