Question

1. what causes the change in seasons on earth?

the tilt of earth on its axis and the earth revolving around the sun
the sun revolving around earth and the moon revolving around the sun
the tilt of earth on its axis and the sun revolving around the earth
the earth revolving around the sun and the moon revolving around the earth

Explanation:

The Earth's seasons are caused by two factors: the tilt of the Earth's axis (about \(23.5^{\circ}\)) and the Earth's revolution around the Sun. As the Earth orbits the Sun, different parts of the Earth receive varying amounts of sunlight throughout the year. When a hemisphere is tilted towards the Sun, it experiences summer (more direct sunlight, longer days). When tilted away, it has winter (less direct sunlight, shorter days). The Sun does not revolve around the Earth (that was the old - geocentric model, which is incorrect). The Moon's revolution around the Earth mainly affects tides and has no direct role in causing seasons.
