Question

solstice
equinox
perihelion
aphelion
what causes the variation in daylight hours between summer and winter? *
earths distance from the sun
earths axial tilt
earths rotation speed
the moons phases

Explanation:

• First question:
• Solstice is related to the longest or shortest day. Equinox is when day and night are equal. Perihelion is the closest point to the Sun. Aphelion is the farthest point from the Sun.
• Second question:
• Earth's distance from the Sun has a minor effect on seasons. Earth's rotation speed affects day - night cycle. Moon's phases have no relation to summer - winter daylight variation. Earth's axial tilt causes different hemispheres to receive more or less sunlight, leading to variation in daylight hours between summer and winter.

Answer:

• First question: D. Aphelion
• Second question: B. Earth's axial tilt
