Example: air near the ground on a hot day is heated by the hot surface. It therefore expands, so its density falls and it rises to be replaced by the coolder air above it. After a while in contact with the cooler air higher up it stops rising and merges with the atmosphere, so a cycle is set up. This cycle is called convection.

What is a great sentence for convection?
Convection is defined as the transfer of heat through a fluid,(liquid, or gas form) caused by motion of molecules. A pot of water on the stove, warms through the process of convection.
Which transfer of energy occurs mainly through the process of convection?
Energy transfer by convection is primarily restricted to fluids. One of the significant modes of heat transfer is convective heat transfer.
Which process causes the transfer of energy by air currents within the Earth's atmosphere?
convection
What type of Heat transfer is found in a hair dryer?
A hair dryer will use convection.
How does the process of convection rely on radiation?
It relys on it because convection are the air currents that have to be heated by something, so you need objects to radiate heat to heat up the air to start the current
During convection what happens?
particles move faster
What process causes the warm air to move upward over the land during the day?
convection
What are effects of connection currents in the mantle?
The flow of mantle effects convection currents in the mantle. This process happens as hot material within the mantle begins to rise. As it rises, it begins to cool and then sinks. This process repeats as a cycle of convection currents.
How convection happens?
Convection happens due to the transfer of heat by the motion of a heated fluid such as air or water.
What happens to particles during the process of convection?
During convection, particles in a fluid gain kinetic energy, become less dense, and rise. As they rise, they transfer heat through the fluid by bumping into other particles. Once they cool down or lose energy, they become denser and sink back down, creating a continuous circular motion that transfers heat.
During convection hot material then moves to the side and . This circular pattern is called a convection current?
During convection, hot material rises due to its lower density, creating a convection current. As the material moves to the side, it cools down, becomes denser, and eventually sinks, completing the circular pattern of convection. This process is driven by temperature differences within the fluid.
Why does convection happens?
convection happens because fluids become less dense and expand and riseas they are heated.
The type of energy called convection happens as a result of?
Convection currents
What happens during the process of making pickles?
yumm
How does greese get in a potato?
That happens during the cooking process.
Heat is transferred by the movement of currents within a fluid by a process called what?
convection
What occurs during the process of convection?
During convection, heat transfer happens through the movement of fluid (liquid or gas) due to temperature differences. As the fluid near a heat source gets warmed up, it becomes less dense and rises, while cooler fluid sinks to replace it. This creates a continuous circulation pattern that helps to equalize temperatures within the fluid.
