convection
Convection currents transfer heat from one place to another by mass motion of a fluid such as water, air or molten rock. The heat transfer function of convection currents drives the earth's ocean currents, atmospheric weather and geology. Convection is different from conduction, which is a transfer of heat between substances in direct contact with each other.

Ocean currents as well as winds distribute heat and moisture around the earth. Winds can bring in cold fronts or warm fronts.
Ceramic is a porous material. It has many small air pockets in it which help to reduce heat conduction. The heat does not transfer easily to air so the transfer is held back by these pockets and the heat is retained in the contained liquid or material. The atomic structure of ceramic accounts for its ability to retain heat due to the configuration of bound atoms or ions. A more crystalline structure will have less heat transferred and will retain more heat.
It is because of the convection currents that occurs in the mantle. The heat in the mantle circulates (we know that hot air goes up and cold air goes down) so the plates in the Earth moves. The convection currents are caused by the very hot material at the deepest part of the mantle. The heat causes the land to rise while cooling results the land to sink.

Wind and water. Air currents (wind) carry heat poleward. This is mainly heat transfer by convection. Water currents carry heat poleward. This is heat transfer by convection and conduction.
The transfer of heat by the movement of air currents in the Earth's atmosphere is called convection. This occurs as warmer air rises and cooler air sinks, creating a continuous cycle of heat transfer.

The transfer of heat by the movement of air currents in Earth's atmosphere is an example of convection. As warmer air rises and cooler air sinks, heat is transferred through the circulation of air in the atmosphere.
Convection heat transfer creates currents and cannot occur in solids. Convection involves the transfer of heat through the movement of fluids (liquids or gases) due to differences in temperature and density. This process helps distribute heat in fluids, such as air and water.
The transfer of energy from land or water to air by direct contact is known as convection. As the surface of the land or water gets heated by the sun, it transfers this heat energy to the air molecules in contact with it. These warm air molecules rise, creating air currents and leading to the transfer of heat from the surface to the air.
Heat transfer by up and down currents refers to the movement of heat vertically in a fluid or air due to the difference in temperature. As warm air rises and cold air sinks, this process creates a natural circulation that helps distribute heat more evenly in a space. This type of heat transfer can be observed in processes like convection currents in a room or oceanic currents.
Convection is the process by which heat is transferred through the movement of air or fluid. In this case, heated air rises and cooler air sinks, creating air currents that transfer heat within a space.

ConvectionHeat energy is transferred primarily by air movements, storms, and ocean currents. Since the earth is heated unevenly, the energy is redistributed. Air movements, otherwise called wind, are one important mechanism. Storms, which contain water vapor and water, also transfer heat. When water turns to water vapor it absorbs heat and when water vapor condenses to water, heat is released. Therefore, storms are important movers of heat. Ocean currents also transfer heat as cold currents move to warmer areas and warm currents move to colder areas.air movements, storms, and ocean currents
