Why is gravity important to the earth?

Answer 1

== == If the sun's gravity dissapeared, then, even if we still got light and warmth, the earth would stop circling the sun and start floating away into space. It would get colder and colder, and finally the earth would float too far away and freeze.

Answer 2

The earth doesn't need either really, but to maintain its stable course it needs the sun. To maintain life it needs the sun to warm the earth and provide a source of energy to plants and animals. The moon is important to life, it has its own gravitational pull on the oceans of the earth effecting how the oceans shift causing animals to migrate or shift as well.

==========

The earth might do OK without the moon, but without the sun it would be a ball of ice with no life since the sun supplies nearly all the energy - directly or indirectly - used by living things to sustain life.

Answer 3

Gravity is important to Earth because it keeps everything on the planet grounded, including people, objects, and the atmosphere. It is responsible for maintaining the planet's atmosphere, oceans, and shape. Gravity also plays a key role in the Earth's orbit around the Sun and in the formation of celestial bodies.

Answer 4

The sun is a very dense ball of gas (hydrogen and helium); it has so much gravity due to the large amount of matter in a relatively small place.

Answer 5

Among many other things: Gravity holds the Earth together in the first place. Also, it allows the Sun to shine.
