Answer 1

To arrange the components of the universe from smallest to largest, the correct order is:

1. Planets
2. Stars
3. Nebulae
4. Galaxies

So, the final arranged list is:

1. Planets
2. Stars
3. Nebulae
4. Galaxies

Answer 2

Stars have life spans and are born in a ___________________, a cloud of dust and gas. Gravity pulls the dust and gas together. Stars die when they use all their fuel. Huge groups of stars make up ________________. Galaxies are formed by spinning clouds of gas and individual stars are born within galaxies.

Nebula
Atmosphere
orbits
galaxies

Answer 3

Stars have life spans and are born in a nebula, a cloud of dust and gas. Gravity pulls the dust and gas together. Stars die when they use all their fuel. Huge groups of stars make up galaxies. Galaxies are formed by spinning clouds of gas and individual stars are born within galaxies.

So the completed sentences are: Stars have life spans and are born in a nebula, a cloud of dust and gas. Huge groups of stars make up galaxies.

Answer 4

The best way to describe the Sun in comparison to other stars would be

a) average brightness compared to most stars
b) dimmer compared to most stars
c) brighter compared to most stars

Answer 5

The best way to describe the Sun in comparison to other stars would be:

a) average brightness compared to most stars.

While the Sun is brighter than many stars that are visible to the naked eye, it is considered an average star (a G-type main-sequence star, or G dwarf) when compared to the entire population of stars in the universe. Many stars are considerably brighter (like O and B-type stars), while others are dimmer (like M-type stars).

Answer 6

Which observation indicates that Aristotle’s geocentric model was flawed?(1 point)
Responses

The stars appear to be farther from Earth than the moon is.
The stars appear to be farther from Earth than the moon is.

The sun appears to move across the sky each day.
The sun appears to move across the sky each day.

Objects in the sky appear in different areas of the sky each night.
Objects in the sky appear in different areas of the sky each night.

The moon’s appearance changes throughout the month.

Answer 7

The observation that indicates that Aristotle’s geocentric model was flawed is:

Objects in the sky appear in different areas of the sky each night.

This observation supports the idea of heliocentrism, as the apparent movement of celestial objects suggests that the Earth is not the center of the universe, but rather that it and other planets orbit around the Sun. The changing positions of stars and planets over time would be difficult to explain with a strictly geocentric model.
