It doesn't have to. But the probability that it will is so large
that it's accepted as a law in thermodynamics.
Heat moves from the warmer object to the cooler object through a process called conduction. The vibration of particles in the warmer object transfers energy to the particles in the cooler object, causing them to heat up.
Heat moves from warmer things to cooler things through a process called conduction, where the kinetic energy of the molecules in the warmer object is transferred to the molecules in the cooler object through direct contact. The heat transfer continues until both objects reach thermal equilibrium, with the same average kinetic energy among their molecules.
This is called "heat transfer"...the answer was in the question! In a thermal gradient, energy (in the form of heat) always wants to go to areas of deficiency. Thus, there is a movement of this energy (which is called "Heat Transfer") from the warmer body to the cooler body.
Heat is thermal energy. If two objects having different temperatures are brought into contact, heat will always flow from the warmer one to the cooler one, until their temperatures are equal.
Hot air rises and cooler air moves in to replace the warmer air. This creates an updraft, and wind. This is normally caused by the suns rays warming the mantle of the earth.

No, heat will not move from the ground to the atmosphere by conduction if the air is warmer than the ground. Conduction involves heat transfer from a warmer object to a cooler object, so in this case, heat will not flow from the ground to the already warmer air.

Thermal energy moves from warmer areas to cooler areas through the process of conduction, convection, or radiation. Heat will flow from the warmer object to the cooler object until thermal equilibrium is reached.
A heat pump is able to move heat from a cooler region to a warmer region by utilizing a refrigeration cycle that uses a refrigerant to absorb heat from the cooler area and release it in the warmer area. Through the compression and expansion of the refrigerant, heat energy is effectively transferred from one location to another, even against the natural flow of heat.
A heat pump uses a refrigerant to absorb heat from a cooler space and release it in a warmer space. This is accomplished by circulating the refrigerant through a cycle of compression and expansion, which allows it to draw heat from a colder area and release it in a warmer area.
When cold transforms into heat, it is due to the transfer of thermal energy. This process occurs when heat is added to a cold object, causing the molecules within the object to move faster and increase in temperature. This transformation is known as thermal energy transfer, where heat flows from a warmer object to a cooler object until they reach thermal equilibrium.
Thermal energy that can move from one substance to another is called heat. Heat always moves from a warmer substance to a cooler one. An increase in temperature means that heat moves into a substance.
There are basically three methods of heat transfer; what causes the heat transfer differs in each of the three methods. Conduction: Atoms/molecules simply bump into one another, transferring energy. Convection: Larger amounts of liquids or gases move up if they are hotter, because they are less dense. Or they move down if they are colder, because they are more dense. Eventually the heat will be transferred by conduction as well, or the substances become mixed. Radiation: Any object emits electromagnetic radiation according to its temperature. This can be absorbed by other objects.
