When the sun warms the earth, the warmed earth emits infrared radiation. Some of this is captured by greenhouse gases in the atmosphere which then warms up. The more greenhouse gases there are, the warmer it gets. And that is how global warming works.

Convection currents form when warm air rises and cold air sinks What causes the warm air to rise and the cold air to sink?
a difference in density
Convection currents form when warm air rises and cold air sinks. What causes the warm air to rise and the cold air to sink?
a deference in density
What causes the warm moist air to rise?
At the equator, intense sunlight warms the air and causes evaporation of water from the ocean. As the air heats up, it expands and rises.
What happens to the warm air when it overtakes the cold air?
the warm air will rise
What effect does cool temperature have on air?
Cool air is denser than warm air, making it less likely to rise. It also cannot hold as much moisture as warm air.
what type of flight causes birds to rise in warm air?
It is caused when a bird runs into warm air and it causes it to fly. About any bird will fly when they run into warm air, except the ones that can't fly.

How do fronts cause weather to change?
When fronts meet, the cool air undercuts the warm air and causes the warm air to rise and create tornadoes, associated with rain.
What causes the warm moist air to rise?
At the equator, intense sunlight warms the air and causes evaporation of water from the ocean. As the air heats up, it expands and rises.
What happened to the air when it is warm?
Warm air will rise.
Why do we use warm air in a hot air balloons?
This is because of convection. Hot air rises and cool air falls which causes the balloon to rise.
How does water go from the earth into the air?
Water goes from the earth into the air because of the effect of the sun on the earth which causes warm air to rise.
What happens to the warm air when it overtakes the cold air?
the warm air will rise
What effect does cool temperature have on air?
Cool air is denser than warm air, making it less likely to rise. It also cannot hold as much moisture as warm air.
What is the primary energy source that causes warm moist air to rise over tropical oceans?
The heat of the sun.
What is the type of air when it rise?
It is the warm air
