Cold water forced to the surface by pressure is known as upwelling. Upwelling occurs when winds push surface water away from a coastline, causing deeper, colder water to rise and take its place. This process brings nutrients from the ocean floor to the surface, supporting the growth of phytoplankton and other marine life.

Why is the vapor pressure of a warm lake higher than the vapor pressure of a cold lake?
The vapor pressure of a warm lake is higher than that of a cold lake because higher temperatures increase the kinetic energy of water molecules, causing them to evaporate more easily and increase the pressure of water vapor above the lake's surface.
What happen when we boil water and expose the steam to a cold surface?
When we boil water and expose the steam (water vapor) to a cold surface, it will condense into tiny drops of water on the cold surface. If you can see the 'steam'rising above the water, it has already condensed into tiny droplets of water in the cool air.
How can the hot water be at a higher pressure than the cold mains in an unvented system?
In an unvented system, hot water can be at a higher pressure than the cold mains due to the presence of a pressure-reducing valve on the cold water supply. This valve controls the pressure of the cold water coming into the system, allowing the pressure of the hot water, which is heated and stored at a higher temperature, to be higher. Additionally, the expansion vessel in the system helps regulate pressure fluctuations by absorbing excess pressure from heating water.
Why does water go down in a cold place and hot water goes up in an airtight place?
Cold water is denser then hot water and weighs more so hot water will always stay on top of cold water no matter the pressure in the line or volume unless forced by flow hot water water will always be on top.
What happens when steam in the bathroom hits a cold surface like a miror?
When steam in the bathroom hits a cold surface like a mirror, it condenses into water droplets. This is because the cold surface causes the steam to lose heat energy, changing it back into liquid water.
Is hot water pressure and cold water pressure equal in pressure?
Pressure is the same whether hot or cold.
How does warm air mass being pushed into a region of cold air affect atmospheric pressure?
When a warm air mass is forced into a region of cold air, it becomes denser and sinks below the cold air. This creates a zone of high pressure as the cold air is heavier and exerts more pressure on the surface. The movement of air from high pressure to low pressure causes winds to form.
What is condensation?
Water which collects as droplets on a cold surface when humid air is in contact with it.
How often does it flood on mars?
There is no liquid water on the surface of Mars. The atmospheric pressure is so low and the temperatures are so cold that any water on the surface would freeze and boil at the same time.
Why is the vapor pressure of a warm lake higher than the vapor pressure of a cold lake?
The vapor pressure of a warm lake is higher than that of a cold lake because higher temperatures increase the kinetic energy of water molecules, causing them to evaporate more easily and increase the pressure of water vapor above the lake's surface.
What current brings cold water to the ocean surface?
An upwelling is a current in the ocean that brings deep, cold water to the ocean surface.
What happen when we boil water and expose the steam to a cold surface?
When we boil water and expose the steam (water vapor) to a cold surface, it will condense into tiny drops of water on the cold surface. If you can see the 'steam'rising above the water, it has already condensed into tiny droplets of water in the cool air.
Do currents of cold sinking air produce regions of higher pressure or lower pressure at the earths surface?
Currents of cold sinking air produce regions of higher pressure at the Earth's surface. As air sinks, it compresses and becomes denser, leading to an increase in pressure at the surface. This high pressure often leads to fair weather and clear skies.
What side of the water does the pressure tank go hot or cold?
Install on cold water line.
What do you call the circulation in ocean that brings deep cold water to the surface?
Ocean convection currents move the deep cold water to the surface of oceans.
How can the hot water be at a higher pressure than the cold mains in an unvented system?
In an unvented system, hot water can be at a higher pressure than the cold mains due to the presence of a pressure-reducing valve on the cold water supply.

Why did the water rush into the erlenmeyer flask when it was submerged in the cold water?
1. When the flask was placed into the cold water, the colder air molecules in the flask move slower, putting out less pressure. With the decrease in air pressure inside the flask, the now greater pressure outside pushes water into the flask until the pressure inside equals the pressure outside.
