• Pluto

Open Ended

What is the order of the planets from the sun outward?

Multiple Choice

Imagine you are a scientist studying the formation of the solar system. What role does gravity play in this process?

• Gravity only affects the formation of stars, not the formation of planets in the solar system.

• Gravity causes the expansion of a giant molecular cloud, preventing the formation of a protostar and planets.

• Gravity caused a cloud of dust and gas to contract, forming the Sun. Gravitational attraction also caused the gas and dust orbiting the sun to clump and from objects that orbit the sun.

Explain in your own words, the definition of both rotation and revolution. Explain if there is any relationship between these two things. Using the inner planets as some examples, does your position in the solar system determine the length of either your rotation or revolutions?

Multiple Choice
