How Does Earth’s Rotation and Tilt Affect It’s Biosphere?

Compare To Mars Rotation And Tilt (If Any).

Does Mars Experience Seasonal Changes And Weather Conditions Like Earth?

Earth’s rotation causes periods of sunlight and darkness (which are day and night). Earth’s tilt makes the amount of sunlight reaching any certain spot on Earth to vary over the different times of the year. This causes the seasons and in the Northern Hemisphere when the North Pole is pointing toward the sun it is summer and the days last longer and the sun climbs higher in the sky. This makes the days longer and hotter. Winter is the opposite.

Mars has a pretty similar rotation and tilt to that of Earth. Because Mars is much further from the sun than Earth its orbit takes almost twice as long so a Mar’s year is almost twice as long as an Earth year. This makes the seasons on Mars about twice as long as those on Earth. It does not get nearly as hot on Mars during the summers but it gets much colder than on Earth during the winters.
