What is ovulation?
Ovulation is the process in which a mature egg is released from the ovary. After it's released, the egg moves down the fallopian tube and stays there for 12 to 24 hours, where it can be fertilized.
Sperm can live inside the female reproductive tract as long as five days after sexual intercourse under the right conditions.
Your chance of getting pregnant is highest when live sperm are present in the fallopian tubes during ovulation.

Explanation:
If the earth was tilted, there would be small changes in temperature, but there will be no seasons. The Earth's axis is now inclined at around 24 degrees. This is the main reason for the changing of the seasons. The Northern Hemisphere is in the warm season when the Earth is slanted toward the sun, and the Northern Hemisphere is in the cold season when the Earth is slanted away from the sun. The cycle repeats itself every year because the Earth rotates around the sun at a known and generally constant rate. The sun is higher in the sky during the warm season, making it warmer, and lower in the sky during the cool season, making it colder.
Hope this helps :)
