In terms of gravity, as distance increases...

• the gravitational pull on an object increases

• the gravitational pull on an object decreases

• the friction on an object increases

• the friction on an object decreases

Which 2 variables determine gravitational pull?

• gravitational pull does not change; therefore, there are no variations that determine it

• distance between the objects

  and

  ages of the objects

• distance between the objects

  and

  masses of the objects

• ages of the objects

  and

  masses of the objects

In terms of gravity, the larger the mass---

• the larger the gravitational pull of an object

• the smaller the gravitational pull of an object

• the larger the distance from the Sun

• the shorter the distance from the Sun

Earth can support life because it has water, an atmosphere, and weather.

Which of the following also contributes to supporting life on Earth?

Why does Earth's distance from the Sun make it the perfect place for life to exist?

• it impacts temperature.

  Earth isn't

  too close or

  too far away (too hot or cold)

  from the Sun

• the distance from the Sun impacts gravity.

  Earth isn't

  too close or

  too far (too little

  or too much gravity)

  from the Sun

• the distance from the Sun impacts the atmosphere.

  Earth isn't

  too close or too far (none or too much atmosphere)

  from the Sun

• the distance from the Sun impacts the presence of water.

  Earth isn't

  too close or too far (none or too much water)

  from the Sun

In our Solar System, there are 8 celestial objects that are classified as planets.

Planets must have exact conditions to support life as we know it.

Which of the following explains why some planets wouldn't be suitable for human life?

• Some planets

  have no water

  or anything that could be made into water.

• Some planets

  are too close or

  too far away

  from the Sun.

• Some planets

  do not have an atmosphere.

• All of the above.

Earth's atmosphere is composed of the following gases.

To support human life, a planet's atmospheric composition needs to be made of predominantly---

• carbon

  and

  argon

• nitrogen

  and

  oxygen

• carbon

  and

  oxygen

• nitrogen

  and

  argon

Which of the following characteristics of Earth allow life to exist here?

1. 1. presence of water

2. 2. proximity to the Sun

3. 3. composition of the atmosphere

4. 4. presence of the Moon

• 1 and 2 only

• 1 and 3 only

• 1, 2, and 3 only

• 1, 2, 3, and 4
