Radiation is the most important process of heat propagation, because it is through it that the heat of the sun reaches the earth. Without this process there would be no life on earth. While conduction and convection occur only in material media, radiation also occurs in a vacuum, so it is possible for the sun to heat the earth evenly.

The heat radiated by the sun heats the water of rivers, lakes, seas and oceans occurring the phenomenon of evaporation during the water cycle. At this point, the liquid state of water changes to its gaseous state as it moves from the earth's surface to the atmosphere. For this reason we can say that the sun can accelerate the water cycle.

Although the Earth's orbit around the Sun is an ellipse, not a circle, the distance from Earth to the Sun varies by only 3%, with the Earth being closest to the Sun from January 4-7 each year, depending on leap year. But it's easy to remember that the northern hemisphere of the earth is also closer to the sun in January and it's winter there, while it's summer in the southern hemisphere. So we cannot say that the earth is closer to the sun in summer, but between January 4th and 7th.

Living conditions on earth are a puzzle to astronomy. A little closer to the sun - and we'd be a greenhouse and toxic high-pressure gas plant like Venus. A little farther - and the gases would escape, the water would freeze, there would be at most microbes, as on Mars. The earth is the perfect distance to house water, oxygen, carbon and complex life forms.

Surface Waves are seismic waves that propagate to the Earth's surface and result from interference between P waves and S waves (called volumetric waves). It is to the surface waves that are due to the great destruction caused by the earthquakes. The sun does not interfere with the creation of these waves, which is a factor caused by the movement of the earth and other geological terms.
