Question

1. what is the greatest cause of earths seasons? earths distance from the sun at various times in its orbit earths tilt on its axis changes in temperature at various times during the year the summer and winter solstices

Explanation:

The Earth's tilt on its axis causes different parts of the Earth to receive varying amounts of sunlight throughout the year. This tilt leads to the changing seasons. The distance from the Sun has a negligible effect on seasons (Earth's orbit is nearly circular). Changes in temperature are a result of seasons, not the cause. The solstices are specific points in the year when the tilt causes extreme sunlight distribution (longest and shortest days), but the tilt itself is the fundamental cause.

Answer:

Earth's tilt on its axis
