Suppose a person built a sandcastle of moon sand on the moon. What would that person find there a month later?

The sandcastle would remain the same size because the moon has no wind.

What problem do scientists run into when trying to make an accurate model of the solar system

It's difficult to show the size of the planets and distance in one model

Why is the pressure so high deep inside the outer planets?

They have very large gas masses.

Which of the following is not a reason for Venus being such a hot inhospitable planet?

Venus is about the size of Earth

Why do students and scientists construct scale models of natural phenomena?

to better observe patterns and relationships

If the moon were to double in size, how would the gravitation force between the moon and earth change?

The gravitational force between earth and moon would increase

How does distance affects gravity?

Gravity increases with decreasing distance.

Which of the following statements about the Milky Way and Andromeda galaxies is true?

They both exert a strong gravitational pull on each other.

Why do objects orbit the sun?

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

Questions 13

Answers

1
Which planet is most similar in size to Earth?
Mars
Jupiter
Neptune
Venus
2
Suppose a person built a sandcastle of moon sand on the moon. What would that person find there a month later?
The Moon's wind would have made the castle bigger by depositing more sand
The castles gravity would have attracted more sand
The sandcastle would remain the same size because the moon has no wind.
The moon's wind would have blown the castle away
3
What problem do scientists run into when trying to make an accurate model of the solar system
It is impossible to show the correct scale of the size of the planets
There are no problems, I have seen plenty of models of the solar system
It's difficult to show the size of the planets and distance in one model
It is impossible to show the correct scale of the distances between planets
4
Which of the following planets is largest?
Earth
Mercury
Neptune
Mars
5
Why is the pressure so high deep inside the outer planets?
They are very far from the sun.
They have very large gas masses.
They have very large solid masses.
They have rings.
6
Which of the following is used by scientists to organize Earth’s history?
mass extinctions
layers of rock
geologic time scale
fossil record
7
Which of the following is not a reason for Venus being such a hot inhospitable planet?
Venus is about the size of Earth
Venus is closer to the sun than the earth
There is a very strong greenhouse effect
Venus has an atmosphere that is mostly CO2 and methane
8
Which two types of celestial objects are often similar in size?
comets and planets
moons and meteors
asteroids and comets
planets and meteors
9
Why do students and scientists construct scale models of natural phenomena?
to correct mistakes in nature
to better observe patterns and relationships
to collect data from natural events
to define new units of measurement
10
If the moon were to double in size, how would the gravitation force between the moon and earth change?
The gravitational force would be too small to hold the big moon in orbit
The gravitational force between earth and moon would increase
The gravitational force between earth and moon would decrease
The earth would begin orbiting around the giant moon
11
How does distance affects gravity?
Gravity is zero at any point in the solar system.
Gravity remains the same regardless of distance.
Gravity increases with decreasing distance.
Gravity increases with increasing distance.
12
Which of the following statements about the Milky Way and Andromeda galaxies is true?
The Milky Way is a spiral galaxy, and the Andromeda galaxy is not.
The Milky Way galaxy is larger than the Andromeda galaxy.
They are both moving away from each other.
They both exert a strong gravitational pull on each other.
13
Why do objects orbit the sun?
The sun is so bright that objects are forced away.
The sun is so massive that it has the most gravity.
The sun is releasing heat and pushing objects away.
The sun is moving so quickly that other objects move around it.
