1. What is the relationship between the Earth, Moon, and Sun?

Ans. The Earth, Moon, and Sun are interconnected in a system where the Earth orbits the Sun, and the Moon orbits the Earth. This relationship affects various phenomena such as tides, eclipses, and the changing phases of the Moon.

2. How do the Earth and Moon affect tides?

Ans. Tides are caused by the gravitational pull of the Moon and the Sun on Earth’s oceans. The Moon’s gravity creates bulges in the water, leading to high tides, while areas between these bulges experience low tides.

3. What are solar and lunar eclipses?

Ans. A solar eclipse occurs when the Moon passes between the Earth and the Sun, blocking the Sun's light. A lunar eclipse happens when the Earth is positioned between the Sun and the Moon, causing the Earth's shadow to fall on the Moon.

4. How long does it take for the Moon to orbit the Earth?

Ans. The Moon takes about 27.3 days to complete one orbit around the Earth. This period is known as a sidereal month, but due to the Earth's own movement around the Sun, the phases of the Moon take about 29.5 days to cycle through.

5. Why do we see different phases of the Moon?

Ans. The different phases of the Moon are a result of the Moon's position in relation to the Earth and the Sun. As the Moon orbits the Earth, varying portions of its surface are illuminated by the Sun, creating phases such as new moon, crescent, half, gibbous, and full moon.
