Radiation warming
convention and conduction
Conduction in a solid is basically the passage of heat from one particle to the other. Because the particles in solids are close together they pass heat along much more swiftly than a liquid or a gas. Water in a central heating system moves the heat along the heat that is in the water is pumped from radiator to radiator, which is neither by conduction, convection, or radiation. Liquids are usually less good at passing heat along because their particles are much more widely spaced out, and they are further apart in gases. However liquids and gases can pass heat along by convection.
All of those heat transfer methods require a medium - gas, liquid or solid. Heat is transferred from warmer molecules to adjacent cooler ones in conduction. Heat is transferred by moving gas or liquid in convection/advection. Space is essentially a vacuum. Molecules are not dense enough to transfer heat to one another, there is not a dense enough gas to convect - leaving only radiation as the heat transfer method.
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.
three types of heat transfer work together to heat the troposphere by heating the solid with (conduction) air ( convection) and radiation from the sun.

they are in a transfer of how the atmosphier is heated
convection,radiation,and conduction?
Convection currents move many weather systems on the earth. Solar radiation warms the earth. The solids heat faster and air over the shore area rises. Cooler air over the water rushes in to replace it. Convection currents also occur in the oceans Air cools as it rises and clouds form.
Radiation warming
They all move heat energy from a hot object to a cooler one.
convention and conduction
a boiling pot because the stove radiates heat to warm the pot. the pot is touching the stove which is conduction. last when the pot is heated and boiling the steam is a form of convection. conduction could also be ice melting on a hot surface>
A convection current is a natural flow or circulation of fluid due to a variation in its density due to temperature differences. As a fluid's temperature increases, its density reduces, and the fluid rises to be replaced by fluid at a lower temperature. Convection, together with conduction and radiation, is a method of heat transfer.
electrons get transferred in form of energy when photon of energy higher than binding energy falls on it electron is ejected in form of energy by conduction,convection ,radiation
