# What is convection short answer?

## What is convection short answer?

Convection is the circular motion that happens when warmer air or liquid — which has faster moving molecules, making it less dense — rises, while the cooler air or liquid drops down. Convection is a major factor in weather. That current can result in wind, clouds, or other weather.

## What is convection direction?

. Convection atmospheric motions in the vertical direction. In meteorology, convection refers primarily to atmospheric motions in the vertical direction. As the earth is heated by the sun, different surfaces absorb different amounts of energy and convection may occur where the surface heats up very rapidly.

What is convection definition and example?

Convection is the transfer of heat by circulating it through air or liquids. The cold water is pushed downward towards the hot bottom of the pot due to convection currents, and the process continues. 2. A Hot Air Balloon. Hot air balloons rise due to the propensity of warmer air to be less dense than the air around it.

What is advection and convection?

Meteorology. In meteorology and physical oceanography, advection often refers to the horizontal transport of some property of the atmosphere or ocean, such as heat, humidity or salinity, and convection generally refers to vertical transport (vertical advection).

### What is meant by convective heat transfer?

Convection (or convective heat transfer) is the transfer of heat from one place to another due to the movement of fluid. Convection is usually the dominant form of heat transfer in liquids and gases. Note that this definition of convection is only applicable in Heat transfer and thermodynamic contexts.

### What is convection Class 9?

Convection is the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids. The initial heat transfer between the object and the fluid takes place through conduction, but the bulk heat transfer happens due to the motion of the fluid.

What is convection class 7th?

Convection: The process of heat transfer from one part of a fluid to another part by the actual movement of the particles of the fluid is called convection. Liquid and gases are heated by the process of convection. For example, the heat from the sun reaches the earth through radiation mode.

What is convection in Brainly?

Brainly User. When a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along. This type of heat transfer is called convection. The fluid above a hot surface expands, becomes less dense, and rises. kaypeeoh72z and 8 more users found this answer helpful.

## What is convection Class 11?

Convection is the process of heat transfer from hot body to cold body by the bulk movement of the molecules within fluids such as gases and liquids. Convection is the process of heat transfer in fluids by the actual motion of molecules in the fluids. It happens in liquids as well as gases. It may be natural or forced.

## What is advection and conduction?

Its quite simple. Advection is the transport of energy (say heat) by movement of bulk fluid. On the other hand, if you consider the fluid layer sticking to the solid surface, it actually gains heat energy by conduction only. Now, Conduction and Advection put together gives you convection.

What is conduction in geography?

The air in interaction with the land gets heated gradually and the upper layers in touch with the lower layers also get heated. This process is called conduction. This process takes place when two bodies of uneven temperature are in contact with one another, there is a flow of energy from the warmer to the cooler body.

What is convection Class 7 Brainly?

Answer: Convection is the circular motion that happens when warmer air or liquid — which has faster moving molecules, making it less dense — rises, while the cooler air or liquid drops down. Convection is a major factor in weather. bolivianouft and 12 more users found this answer helpful. Thanks 5.

### What is meant by directional selection in biology?

Directional Selection in Evolutionary Biology. Directional selection is one type of natural selection in which the phenotype (the observable characteristics) of the species tends toward one extreme rather the mean phenotype or the opposite extreme phenotype. Directional selection is one of three widely studied types of natural selection,…

### What is convection?

What is Convection? 1 Convection is the process of heat transfer in fluids by the actual motion of matter. 2 It happens in liquids and gases. 3 It may be natural or forced. 4 It involves a bulk transfer of portions of the fluid. More

What is the difference between conduction and convection?

The initial heat transfer between the object and the fluid takes place through conduction, but the bulk heat transfer happens due to the motion of the fluid. Convection is the process of heat transfer in fluids by the actual motion of matter. It happens in liquids and gases. It may be natural or forced.

What is directional selection in Massachusetts?

They also are certified in secondary special education, biology, and physics in Massachusetts. Directional selection is a type of natural selection that happens when the extreme phenotype on one end of the spectrum is more favorable than the extreme phenotype on the other end.
