How do the moon and sun affect earth?

Answer 1

The Earth revolves around the sun which causes the seasons. The Earth rotates on it's axis which causes day and night. The moon's gravity stabilizes the Earth's tilt on its axis at approximately 23 degrees, without the moon, the earth would wobble causing major disasters. The moon's gravity also affects our tides.

Answer 2

The sun provides light and heat for life on Earth through photosynthesis. It also creates tides through its gravitational pull. The moon affects Earth's tides through its gravitational pull, which is responsible for the rise and fall of ocean levels.

Answer 3

The light and heat from the Sun provide all of the energy that we use here on Earth; without it, the Earth would freeze solid.

The Moon's effects are less dramatic, but still significant. The Moon is the primary cause of tides, which causes ocean mixing and is a major factor in our weather. Without tides, our oceans would probably become more stratified and layered, and might become more stagnant.
