Answer 1

The correct order for changing models of our solar system, starting with the oldest and ending with the most recent, is:

geocentric, heliocentric, elliptical orbits

This sequence reflects the historical development of astronomical models, beginning with the geocentric model (Earth-centered), followed by the heliocentric model (Sun-centered), and finally the understanding of elliptical orbits as described by Kepler.

Answer 2

A video shows the objects in the solar system orbiting the sun. Why do objects orbit the sun?(1 point)
Responses

The sun is releasing heat and pushing objects away.
The sun is releasing heat and pushing objects away.

The sun is so massive that it has the most gravity.
The sun is so massive that it has the most gravity.

The sun is so bright that the objects are forced away.
The sun is so bright that the objects are forced away.

The sun is moving so quickly that other objects move around it.

Answer 3

The correct response is:

The sun is so massive that it has the most gravity.

Objects in the solar system orbit the sun due to its gravitational pull, which is a result of its massive size. This gravitational force keeps the planets, moons, and other objects in their orbits around the sun.

Answer 4

What would decrease the gravitational pull between the sun and Earth?(1 point)
Responses

if Earth was closer to the sun.
if Earth was closer to the sun.

if the sun was twice its size.
if the sun was twice its size.

if Earth was twice its size.
if Earth was twice its size.

if the sun was farther away from Earth.
if the sun was farther away from Earth.

Answer 5

The correct response is:

if the sun was farther away from Earth.

The gravitational pull between two objects decreases as the distance between them increases, according to Newton's law of universal gravitation. Therefore, if the sun were farther away from Earth, the gravitational pull would decrease.

Answer 6

Suppose a person built a sandcastle of moon sand on the moon. What would that person find there a month later?(1 point)
Responses

the sandcastle would remain in place the same size that it was because the moon has no wind.
the sandcastle would remain in place the same size that it was because the moon has no wind.

The sandcastle would have grown larger because moon sand particles attract other moon sand particles.
The sandcastle would have grown larger because moon sand particles attract other moon sand particles.

The sandcastle would have grown larger by collecting more sand particles because moon sand is blown by the wind.
The sandcastle would have grown larger by collecting more sand particles because moon sand is blown by the wind.

The sandcastle would be much smaller because changing winds would have eroded much of the sand away.

Answer 7

The correct response is:

the sandcastle would remain in place the same size that it was because the moon has no wind.

On the moon, there is no atmosphere, which means there is no wind to erode or change the sandcastle. As a result, it would likely remain in place and keep its size.

Answer 8

How do outer planets differ from inner planets?(1 point)
Responses

They have very large solid surfaces.
They have very large solid surfaces.

They consist of a mixture of gases and liquid.
They consist of a mixture of gases and liquid.

They are smaller than the inner planets.
They are smaller than the inner planets.

They are not different from the inner planets.
They are not different from the inner planets.

Answer 9

The correct response is:

They consist of a mixture of gases and liquid.

Outer planets (Jupiter, Saturn, Uranus, and Neptune) are known as gas giants or ice giants, and they primarily consist of gases and liquids, whereas inner planets (Mercury, Venus, Earth, and Mars) are terrestrial and have solid surfaces.

Answer 10

Use the scenario to answer to question.

A student creates a diagram comparing the sizes of objects in the solar system.

Which two objects are often similar in size?

(1 point)
Responses

comets and planets
comets and planets

asteroids and comets
asteroids and comets

planets and meteors
planets and meteors

moons and meteors

Answer 11

The correct response is:

moons and meteors.

Moons and meteors (which can refer to meteoroids before they enter the atmosphere) often have similar sizes, as many moons are relatively small compared to planets, and meteors can also vary in size but are often small objects.
