Our Solar System

How do scientists believe gravity influenced the formation of the planets in our solar system?

• A large cloud of gas and dust ignited into a planet.

• Gravity pulled the planets out of the Sun.

• A large explosion created the planets.

• Large pieces of debris clumped together to form planets.

How does the Moon's gravity cause the rise and fall of Earth's ocean levels?

• The Sun's gravitational force "pulls" on both the Earth and the Moon at different times.

• Earth revolves on its axis, which causes ocean levels to rise facing the Moon.

• Since the Moon has more mass than Earth, the Moon's gravity causes tides.

• The Moon's gravitational force "pulls" on the oceans
