A convection current is created because, for example, if you have a room with a radiator at the bottom then the radiator will heat the air closest to it at the bottom of the room. When the air is heated it expands which makes it less dense because the particles are further apart. This means that the hot air will then rise above the cool air which was above it, therefore meaning that the cold air has to sink in order to fill in the space below. This cycle then continuous: a convection current.
What else can I help you with?
Cold air moves warm air where?
Cold air sinks and warm air rises. If you are in a warm room of your house and cold air starts leaking in from somewhere, you will feel the area closest to the floor getting colder first. Cold air displaces or takes the place of the hot air forcing the hotter air to rise above. If you have buzzards where you live, watch them over a field. They will circle in a column and rise higher and higher without flapping their wings. They are riding a thermal of warm air that has been heated by the sun. As the warm air rises the birds soar with it. Good proof that hot air rises is a hot air baloon. The hotter the air inside the baloon, the higher it goes.
Explain what the difference between warm and cold air with regards to movement Why does this happen?
Warm air tends to rise due to its lower density compared to cold air, which causes it to be displaced by cooler, denser air. As warm air rises, cold air takes its place, creating a circular motion known as convection currents. This movement happens because warmer air expands and becomes less dense, leading it to ascend while colder air contracts and sinks.
Do convection currents push warm air down and cold air up?
Warm air naturally goes up/rises and cold air has to make a current where it can go until it reaches a warm current which is under the warm air.
What happens when a warm front moves into a cold front?
When a warm front moves into a cold front, the warm air gradually rises over the denser cold air. This can lead to the formation of clouds and precipitation. The warm air displaces the cold air, leading to a gradual increase in temperature and humidity.
Convection currents form when warm air rises and cold air sinks What causes the warm air to rise and the cold air to sink?
Warm air rises because it is less dense than cold air, creating an upward movement. As warm air rises, it cools down and becomes denser, then sinks back down. This cycle of warm air rising and cold air sinking creates convection currents.
When upwelling takes place cold water from the deep ocean does what?
Rises to the surface.
What can be expect when warm air rises and cold air takes its place?
clouds
Is it true that wind is caused when cold air rises and hot air takes its places?
No. The hot air rises because it is less dense and therefore lighter. The cold air takes it's place as it is heavier. This causes wind.
Does wind move from a warm place to a cool place?
Warm air rises over cold air when a warm and cold front connect.
How does air circulation take place?
When air is heated, it expands, it becomes lighter and goes up. Cold air is denser and heavy. That is why it sinks down. When hot air rises, cold air from surrounding area rushes there to fill in the gap. That is how air circulation takes place.
When was The Earth Is Not a Cold Dead Place created?
The Earth Is Not a Cold Dead Place was created on 2003-11-04.
How rising air is produced in Pakistan by monsoon?
the land gets heated up due to summer heat because of which hot air rises and mixes with the cold air ans condensation takes place and rain falls
Where does the story the cold king by Amber Jaeger take place?
The story "The Cold King" by Amber Jaeger takes place in a kingdom known as Aronia, which is a fictional realm created by the author for the narrative. The setting is characterized by snow-capped mountains, icy landscapes, and a castle where the Cold King resides.
Why will wind always be around?
Wind is always around because the sun is always around . A breeze / wind is created when the sun warms up the air. When the air is warmed up, it quickly rises up because heat rises up. As soon as it rises up, the cold air rushes in to take its place and that rush of cool air is wind.
Why does warm air rises above cold air?
Warm air rises above cold air because it is less dense than cold air. As warm air absorbs heat, its molecules gain energy and spread out, causing it to become lighter and rise. This creates convection currents, with warm air moving upward and cold air sinking to take its place.
When warm air rises cold air will what?
The cold air will sink.
Is there a water cycle when it is cold?
Yes, the water cycle still occurs when it is cold. The cycle involves processes such as evaporation, condensation, precipitation, and runoff, which continue to happen even in cold temperatures. In cold regions, water may freeze instead of evaporating, but the overall cycle still takes place.
