Answer:
because the earth take a revolulion around the sun and when it comes nearer to sun then summer season takes place and when the earth goes farther from the sun then winter season occurs like wise nowadays earth has-been away from the sun so winter season.
Answer:
Over the course of a year, the Earth goes on a journey around the Sun. The reason we have seasons is because, during its journey around the Sun, the Earth is tilted. The Earth’s tilt affects the amount of daylight each hemisphere gets, which in turn makes the temperature hotter or colder.
For example, if you live in the northern hemisphere – that’s north of the equator, like in Europe, USA, or India – then winter happens in December, January and February. That’s when the northern hemisphere is tilted away from the Sun, and the days are shorter.
For anywhere south of the equator, such as Australia or Latin America, it’s summer during these months. That’s because the southern hemisphere is tilted toward the Sun, and the days are longer.
Solstices and equinoxes
Every season has a middle point. In summer and winter, these midpoints are called solstices. The summer solstice is the longest day, and shortest night, of the year. The winter solstice is the shortest day of the year, and the longest night.
In spring and autumn, the midpoints are called the equinoxes. At the spring and autumn equinoxes, day and night are the same length.
For thousands and thousands of years – right back to the Stone Age – people have known how to work out when the solstices and equinoxes happen throughout the year.
