Warm air rises at the equator and cold air sinks at the poles creating?
Warm air rises at the equator and cold air sinks at the poles. Warm air expands and cool air contracts and compresses.
When the mantle is heated the magma rises because?
When it is heated it becomes less dense (i.e. lighter). The more dense (i.e. heavier) magma sinks while the less dense magma rises to the top. It will eventually cool again causing a convection current within the mantle.
How does heat cause ocean currents?
Warm water expands and rises, cool water contracts and sinks.
Gas that is less dense than air?
Helium is a gas that is less dense than air. This is why a balloon filled with helium rises when released.
Does cool air sink while warm air rises?
yes the cool denser air sink while the warm less dense rises
How is air pressure affected when an areas of earth is heated?
It expands, rises, and becomes less dense.
Why would heating a hot air balloon make the balloon rise?
Hot air expands. When it expands, it becomes less dense and rises.
When warm air rises it expands causing it to lose the ability to hold water creating?
RAIN
When warm air rises it expands this causes it to lose the ability to hold water creating?
precipitation (rain)
When warm air rises it expands this causes it to lose ability to hold water creating?
This creates clouds and, if there is enough moisture, precipitation.
Does air pressure affect earths weather?
It expands, rises, and becomes less dense.
Warm air rises at the equator and cold air sinks at the poles creating?
Warm air rises at the equator and cold air sinks at the poles. Warm air expands and cool air contracts and compresses.
Why does magma rise when it is nearer to the core?
Water that is heated expands and rises to the surface of the tray. Similarly, the magma expands and rises to the surface of the tray. Similarly, the magma nearer the core expands and rises to top of the mantle.
What happens when air rises?
It expands and cools
Why is the balloon filled with hot air?
Air expands as it is heated, hence, hot air is less dense than cool air. Hence it rises in a surrounding environment of cooler air.
What make fluids rise and sink in a convection current?
Fluids rise and sink in a convection current due to differences in temperature and density. When a fluid is heated, it becomes less dense and rises, creating an upward flow. As it cools, it becomes more dense and sinks, creating a downward flow. This continuous cycle of heating and cooling drives the convection current.
What does air do as it rises?
rising air expands then cools and condenses
