Gravity is what allowed the Earth to hold onto the necessary gases that formed our atmosphere and oceans.
Explanation:
The correct answer is Gravity.
Gravity is what allowed the Earth to hold onto the necessary gases that then formed our atmosphere and oceans. Gravity is the force of attraction between objects with mass, and it keeps the gases from escaping into space.
For example, the force of gravity holds the Earth's atmosphere tightly around the planet, preventing it from drifting off into space. This is why we have air to breathe and an atmosphere that protects us from harmful radiation from the sun.
