As the suns rays hit the solar panel and heats up, the air or liquid heats up and becomes less dense so it rises, this now leaves the dense cool air to heat up which is lower since cool air doesn't rise. The sun heats up the cool air or liquid (usually solar panels are used to heat up hot water tanks) and this rises also, this has now made a 'convection current', the liquid will continue this convection current until its all at the same temperature. Solids do not go through convection current because the particles are closely packed and don't move because they have a definite shape.
The primary source of energy that drives winds in the atmosphere and currents in the oceans is the sun. Solar energy heats the Earth's surface unevenly, creating temperature and pressure differences that lead to the movement of air and water. The rotation of the Earth also plays a role in shaping the patterns of winds and currents.
A simple example is solar energy. The only energy received by the earth from the sun is radiant energy. This heats the air on the earth creating convection currents, or wind. This wind is a mechanical energy.
The three forms of energy from the sun are solar radiation (light and heat), solar thermal energy (used for heating water and spaces), and solar photovoltaic energy (converted into electricity using solar panels).
Ocean waves transfer solar energy by converting wind energy into kinetic energy as they move across the ocean surface. Ocean currents, on the other hand, transport heat energy absorbed from the sun at the equator towards the poles through a system of circulating currents, helping to distribute heat around the globe and regulate climate.
Various sources of energy can be transformed to create electricity, such as coal, natural gas, nuclear, hydroelectric, wind, and solar energy. These energy sources are converted into electricity through different processes like burning, steam generation, or direct conversion of sunlight into electrical energy.

Tornadoes have nothing to do with protecting Earth from the solar wind. Convection currents in Earth's core create a magnetic field that protects against the solar wind.
Two pieces of evidence for solar convection are the presence of granules on the solar surface, which are small convection cells visible in the photosphere, and solar oscillations caused by the motion of convection currents beneath the surface, which can be measured through helioseismology.
Three processes that move energy through the geosphere, hydrosphere, biosphere, and atmosphere are photosynthesis, convection currents, and the water cycle. Photosynthesis converts solar energy into chemical energy in plants. Convection currents transfer heat energy from the Earth's interior to the surface. The water cycle involves the movement of water and energy between the atmosphere, land, and oceans.
Convection currents transfer heat from Earth's core to the mantle, causing the mantle material to flow and create movement in the lithosphere. This movement generates heat due to friction and pressure. So, convection currents help distribute heat within Earth's interior rather than produce it.
Convection is the transfer of heat energy in a fluid. ... Air in the atmosphere acts as a fluid. The sun's radiation strikes the ground, thus warming the rocks.
Granulation on the surface of the Sun is caused by convection currents carrying hot plasma from the interior to the surface. These rising currents of hot plasma create bright cells of gas at the surface, which appear as granules. The motion of these granules is evidence of the convective nature of the Sun's outer layers.

Some parts of the ocean are heated more than others.
When convection occurs in Earth's outer core, it generates electric currents due to the movement of the molten iron and nickel. These electric currents create a magnetic field around the planet, known as the Earth's magnetic field. This magnetic field plays a crucial role in protecting Earth from solar winds and cosmic rays.
The source of energy that drives convection within the Earth's atmosphere is primarily solar radiation. The sun heats the Earth's surface unevenly, causing air to warm and rise in some areas and cool and sink in others, creating convection currents. This process is responsible for distributing heat and moisture throughout the atmosphere.
