How energy transfers in the atmosphere?
Energy transfers in the atmosphere through radiation, conduction, and convection. Radiation is the primary method, where energy from the sun warms the Earth's surface. This heat is then transferred upwards through convection, as warm air rises and cool air sinks. Conduction also plays a role in transferring heat between the Earth's surface and the lower atmosphere.
What type of heat transfer causes heat to rise and cold air to fall radiation conduction or convection?
Convection is the type of heat transfer that causes hot air to rise and cold air to fall. This is because warmer air is less dense and tends to move upwards, while colder, denser air sinks. Radiation and conduction do not directly cause this vertical movement of air.
Compare Convection and conduction?
Convection and conduction are both means of heat transfer involving materials.Convection usually occurs in liquids and gases. Heated parts of these materials expand and become less dense. Pressure from the cooler, less light parts (due to gravity) pushes the lighter heated parts upwards. Near the surface , these cool, sink and circulate upwards again when heated.Conduction can occur in all substances but most efficiently in solids like metals where the particles are close together. If the particles in one part vibrate more when heated to a higher temperature, this vibration is passed along through the material. Conduction can occur in any direction but always from the hottest towards the coolest parts.
What is the similarties between conduction and convection?
If you are talking about heat transfer, these are both methods. Conduction is when something is touching a heat source, and so it starts to heat up. Convection is when heat travels upwards because it is lighter than cool air. I guess the similarity is they are both methods of heat transfer.
How is convection alike in liquids and gases?
Convection is similar in liquids and gases because both involve the movement of particles due to differences in temperature. In both cases, warmer particles rise while cooler particles sink, creating a circular flow of fluids to transfer heat.

What is the method by which heat is transferred into in a fluid liquid or gas?
Transfer of heat in nature occurs through three ways: conduction, convection and radiation. Conduction takes place in solids. Convection in liquids and gases. Radiation takes place in all three media as well as in vaccum.

Convection is similar in liquids and gases because both involve the movement of particles due to differences in temperature. In both cases, warmer particles rise while cooler particles sink, creating a circular flow of fluids to transfer heat.
What is the main process that transfers heat upwards into the chimney?
Convection.
Process of heat loss from the body?
The four mechanisms of heat loss are:Evaporation - When heat is used to convert the water in sweat to water vapour it helps cool the body downRadiation - exposed parts of the body radiate heat away from the bodyConduction - clothes and other objects in contact with the body take the heat upConvection - when air passes over exposed parts of the body it is heated and rises upwards. It is then replaced with cool air (causing convection currents)
What does convection air have to deal with density?
Hot air has less density and will therefore move upwards.
Why fire moves up in direction?
Fire moves upward due to the natural convection process. As the fire heats the surrounding air, it becomes less dense and rises, creating a flow of air upwards. This convection current carries the flames and heat upwards, which is why fire tends to move in an upward direction.
What is hot air spinning upwards?
Hot air spinning upwards is called convection. This occurs when warmer air rises and cooler air sinks, creating a circular motion that transfers heat energy from one area to another. Convection is a natural process that helps distribute heat in the atmosphere and oceans.
Can heat energy travel through space a vacuum by convection?
Actually heat cannot travel through vacuum. sun emits radiations (obviously electromagnetic radiations.) which needs no medium to travel. hence these radiations travel through space and reaches earth where it interacts with atmosphere. when these radiations fall on media like air, water land etc. the radiation is converted into heat energy. Thus it is clear that heat from sun is converted into radiations which travel through space and reaches earth where it is converted to light.
