Question

directions: complete the sentences below about stellar nebula theory using the words provides. use your notes if you need to. 1. our solar system formed from a cloud of gas and dust called a ___________. 2. once these small bodies form they start to clump together forming _________. 3. _________ pulled this gas together into a central location. 4. small bodies form as a solar system forms called _________. 5. _________ planets are closest to the sun and _________ planets are farther away from the sun. 6. ___________ means early or primitive.

Explanation:

1. A solar - system forms from a nebula which is a cloud of gas and dust. The prefix "proto -" is often used to mean early or primitive. Planetesimals are small bodies that form during solar - system formation and clump together to form protoplanets. Gravity is the force that pulls gas and dust together. Rocky planets are closer to the sun and gaseous planets are farther away.
2. For the first blank, the term for the cloud of gas and dust is "nebula", but it's not in the given words, and considering the context and the prefix options, we use what makes the most sense from the list.
3. For the second blank, planetesimals clump to form protoplanets.
4. Gravity is the force that causes the gas to accumulate in a central location.
5. Planetesimals are the small bodies that form during solar - system formation.
6. Rocky planets are inner planets and gaseous planets are outer planets. The prefix "proto -" means early or primitive.

Answer:

1. Proto - nebula (assuming we use the prefix with the general concept of nebula as the closest we can get from the given words)
2. Protoplanets
3. Gravity
4. Planetesimals
5. Rocky; Gaseous
6. Proto -
