6. Please understand the GRAVITY of the situation…
Mass = Gravity
Gravity is the force that holds the solar system together.
The mass (and thus gravity) of the Sun keeps all the planets orbiting around it.
The mass (and thus gravity) of the Earth keeps the Moon orbiting around it.

7. Tidal Forces – Moon and Sun
The Moon has much greater affect on the Earth’s tides because it is closer to the Earth.
When the Moon, Sun, and Earth are aligned (new and full Moon), the tides are the greatest (Spring Tide)

16. Seasons are caused by the Earth’s revolution and tilt
Seasons are caused by the Earth’s revolution and tilt. In the Northern Hemisphere, we are actually closer to the Sun in winter, but our tilt is away from the Sun, so we don’t have direct sunlight. In the summer, even though we are further from the Sun, we receive direct sunlight for the majority of the day, causing it to be warmer.
