Q. earth would not have seasons if it…..

Ans. The tilt of the earth plays a very important role in our seasons. Earth is tilted on an axis of 23.5° with respect to our orbit around the sun. Thanks to these slopes we can experience winter, autumn, summer and spring. When the northern hemisphere faces the sun, solar radiation increases, signaling summer. The opposite happens in winter when sunlight is lower. The Southern Hemisphere experiences the same phenomenon, but the opposite. When it’s summer in the Northern Hemisphere, the Southern Hemisphere survives the winter. The earth’s average temperature is highest in July when it is farthest from the sun and coldest when the earth is closest to the sun. This is called aphelion. Perihelion is when Earth is closest to the Sun and the average temperature is lower.

Unless the earth has tilted or orbits the sun in an upright position, there will be slight variations in temperature and precipitation each year as the earth gets closer to the sun and farther away. In principle we will not have seasons. Earth will be warm at the equator and cold at the poles. The poles will still be the hardest hit because the sun will always be low on the horizon. Other planets are also tilted, such as Uranus at 97°, giving the planet extreme seasons. Because Venus has a low slope, seasonal variations play a minor role.

The Northern Hemisphere experiences its warmest temperatures in July, although July is when we are farthest from the sun due to the tilt of the earth. So not everything is far from the sun, but on the slopes.
