Only one hemisphere has summer at a time, either the Northern or the Southern, while the other has winter. This is determined by which hemisphere is tilted toward the Sun: except for two days each year (the equinoxes), the Earth's tilt means that one pole or the other is angled more toward the Sun.
The tilt results in a combination of longer days than nights (more sunshine) and a lesser angle to the Sun's rays (closer to perpendicular to the surface). Less sunlight is refracted or scattered, and more energy reaches the surface than when the angle is greater.
The earth surface is warmer in the northern hemisphere when it issummer there because of the angle of the sun. For the same reason,the Earth's surface is warmer in the southern hemisphere when it isSummer there.
Cause the sun is facing there
the earth temperature become cool in warm temperature
Visible light is an insignificant portion of the solar radiation that warms the Earth. The sun's infrared radiation, also known as 'heat', is responsible for virtually all of it.
Earth's surface is free to radiate heat into space. The interior is not. The interior does transfer heat the the surface, but rather slowly. It is hot due to residual heat from Earth's formation and from the heat generated by the decay of radioactive elements.
The absorption of thermal energy from the ground heats the lower atmosphere and keeps Earth's surface much warmer than it would if there were no atmosphere. :)
Almost always warmer at the surface.
For the most part, yes. (There are exceptions, of course.)
The rays of the Sun are more focused and thus make the Summer warmer
The bigger the tilt the warmer the summer is.

The process of Photosynthesis is triggered by the sun. The sun is stronger in summer and the temperatures are warmer - the cells metabolisim is increased
