If the earth is warmer than the air, the air in contact with earth will heat the air by conduction. This now-warmer air expands and so can rise and be replaced by cooler air, which is heated in turn. This air movement is convection, so both conduction and convection allow energy to be transferred to the air above it.
There is very little radiative heating of the air near the ground, but clouds do absorb (and reflect) heat from the earth by radiation in the infrared.

Why does burning wood have radiant energy?
Burning wood is a chemical reaction called oxidization. By the application of heat the elements in the wood are rapidly oxidized, combined with oxygen from the air. The resultant energy is heat energy, heat energy has three forms: radiant heat - where the heat travels in a straight line from one surface (the flame or the wood) to another surface, in a straight line of sight. Convection heat - where the heat is carried by a fluid, the air, from one surface to another. (The flame becomes visible when the air is heated to incandescence[visible light]), the surface can be air molecules or solid materials. conduction - molecular transfer of heat from surface to surface by contact. Such as the heat transfer through the wood(the wood heats up). Heat energy always has these three forms. *note: a flame is only superheated air or gasses that have become incandescent. Incandescence is a conversion of heat to light. Light is a radiant energy that can be transformed to heat energy when it is absorbed by a material.
Transfer of heat energy around the Earth from uneven heating of its surface is accomplished by blank air blank pattern?
Transfer of heat energy around the Earth from uneven heating of its surface is accomplished by Global air circulation patterns,
Is the greenhouse effect more pronounced for florists or earths surface?
The greenhouse effect is more pronounced for the earth's surface. Heat rising from the surface is trapped by greenhouse gases. These warm gases heat the air around them as well, also, as the earth' surface again.
How does convection occur in radiators?
Convection is defined in the related link. It requires molecular movement to carry the heat away. The exposed surface of a radiator is hot and in contact with air. The air molecules, when in contact with the surface, pick up heat energy and move away, carrying the heat with them -- hence, convection. =============================
How are conduction and convection involved in warming or cooling the atmosphere?
"After the land and water absorb solar energy, several mechanisms of energy transfer a role in heating the air. On mechanism is *conduction*.. It is the energetic molecules from the land and water collide with molecules in the air that are close to the surface. There collisions transfer energy from the earths surface to the air. The temperature of the land or water beneath it. Then *convection* occurs as the air circulates and distributes the heat. as the lowest layer of air warms it expands , becoming less dense. so as the warm air rises and cooler air descends and takes its place close to the ground" straight from Science Focus 10 textbook page 380

What causes the Sun's energy in Earth's atmosphere to produce winds?
When the act of the Earth's surface absorbing the sun's energy, it turns light into heat. The heat on the Earth's surface warms the air above it causing the air over the equator to get warmer than the surface air.
How is the earths energy tansferred between the earths surface and the atmosphere?
Heat transfer within the atmosphere occurs via all three modes of heat transfer:Conduction - as the air contacts existing heat sources. These might be surfaces that have been heated previously viaabsorptionof solar radiation or from chemical reactions Convection - as warm air mixes with cold air as air currents move the air around and as buoyancy effects cause warm air to rise and cooler air to sink. Radiation - much of the air is composed of heat absorbing molecules such as water vapor. Solar radiation is absorbed by these molecules, causing them to warm up.
How is earths air heated?
Well, the sun gives off energy (or heat). When it hits the Earth's atmosphere, it absorbs that heat or energy. the energy is then trapped in the atmosphere. This is called the "green house effect."
Transfer of heat energy around the Earth from uneven heating of its surface is accomplished by blank air blank pattern?
Transfer of heat energy around the Earth from uneven heating of its surface is accomplished by Global air circulation patterns,
Why is air colder when you go up?
2 reasons - first the earths surface absorbs a lot of the suns heat which helps to keep the air warmer near the surface. Second the higher you go the less dense the air so it has less ability to absorbe heat.
Is the greenhouse effect more pronounced for florists or earths surface?
The greenhouse effect is more pronounced for the earth's surface. Heat rising from the surface is trapped by greenhouse gases. These warm gases heat the air around them as well, also, as the earth' surface again.
