When air loses its heat does it become less dense and sink?
When air loses its heat it actually becomes more dense and sinks which starts a convection current
Describe the movement of air in the huge convection current between 30 north latitude and the equator?
Air rises at the equator and then flows northward. At about 30 degrees north latitude, the air sinks. When it reaches the surface, it flows south, back toward the equator. At the equator, the air rises again and the cycle starts all over.
What is the cycle of convection currents in Earth?
convection currents r a cycle of heat in the mantle. the energy is produced by the heat in the core. the heat rises it becomes cooler and has a greater density. when the desity starts to decrease, it gets hotter and goes round and round in the cycle for many years. but, when the heat is on the top and it rises, the mantle can open up and cause sea floor spreading to occur.
What happens when warm air rises?
When warm air rises it continues to rise until it starts to cool down. Once it starts to cool down it begins to sink allowing more warm air to replace it. This is called convection.
Explain how the earth can heat the air by conduction?
To understand this, you need to know how the earth gets heated. It is obvious, by the sun. As the land gets heated, air molecules in contact with the land starts vibrating as it starts gaining energy from the land.(All bodies want to equilibrium with the other body) As one of the molecule starts vibrating because of heat,it starts transferring its heat to the other molecules via conduction. This process finally heats the entire envelop of air , BY CONDUCTION.
Is barbecue conduction riadiation or convection?
I don't think so - I don't think any convection is involved. I think boiling uses all three though - heat is conducted, this radiates out and heats the water which when heated starts a convection current.
When heat loses its heat does it become less dense and sink?
When air loses its heat it actually becomes more dense and sinks which starts a convection current
Explain how density is involved in convection?
convection means transmission of heat in liquid. consider an example that when u have more tension at that time ur temperament become hot it starts flowingn in our red blood corpuscles (water) so it become hard hence dense.
How does thermal energy from a radiator reach the other side of the room?
Hot air from a radiator reaches the other side of a room by convection current. Convection current is when hot water/ air rises, hot water/ air cools, cool water/ air sinks, cool water/ air warms and then the cycle starts over.
What does the current do?
A convection current is a cycle. The way the cycle works is when the liquid is heated the particles become less dense as it rises to the top and then it becomes more dense so it comes back down again. Then the process starts again.
What is another word for tiny particle that starts with an a?
ATOM
What is an real world example of convection?
cooking and the water starts to boil.
Vegetables are being cooked in a pot on the stove Use the particle theory to explain why the lid starts to jump up and down?
Because the steam is rising to the top and putting pressure to the lid as the steam tries to escape.

THE ENGERGY is Kinetical energy
