1. How does Earth’s rotation cause day and night? (1 point)

As Earth rotates toward the east, the sun appears to rise in the west and set in the east. < this one

As Earth rotates toward the east, the sun appears to rise in the east and set in the west.

Earth rotates in a clockwise direction, which makes the sun appear in the sky during the day.

Earth’s rotation does not cause day and night; its revolution does.

2. Roughly how many times does Earth rotate during each complete revolution? (1 point)
24

28

60

360 < this one

3. Saturn’s day is roughly 10 hours. It takes about 30 years for Saturn to return to the same
point in space. How do Saturn’s periods of rotation and revolution compare to Earth’s?
(1 point)
Earth’s period of rotation and revolution are both shorter.

Earth’s period of rotation and revolution are both longer.

Earth's period of rotation is longer; Earth's period of revolution is shorter. <this one

Earth's period of rotation is shorter; Earth's period of revolution is longer.

4. Why does the sun appear to move westward across the sky during the day? (1 point)
because Earth rotates to the east <this one

because Earth rotates to the west

because the sun moves in a westerly direction

because of the way you are looking into the sky

5. Which of the following statements best describes the biosphere? (1 point)
It is a mixture of gases that contain dust particles.

It contains Earth’s metal core.

It contains all of Earth’s water.

It is the part of Earth that contains living organisms. < this one

6. What is the importance of water on Earth? (1 point)
It keeps the top layer of the geosphere cool.

It allows life to exist. <this one

It provides ice at the poles.

It creates Earth’s blue color from space.

7. Which of the following is an example of a constructive force? (1 point)
buildings collapse in an earthquake

river erosion within the Grand Canyon's rock walls

weathering of a mountain due to rain

a volcano eruption <this one

8. How does gravity affect the moon? (1 point)
It pulls the moon toward Earth.

It pushes the moon away from Earth.

It allows the moon to move in a straight line.

It keeps the moon from colliding with the sun. <this one

8/8 100% correct answers for 8th grade

oui oui! Anon is right! je ne se quoi! (idk if thats how you spell it...)

So is One B?

Ok calm down

Anon is right... I took the quiz and I got 8/8 100% so thanks!

Thank you so much.

yes, 1. B

Anon is right

To get the answer to the question "How does Earth's rotation cause day and night?", you need to understand the relationship between Earth's rotation and the position of the sun in the sky. As Earth rotates towards the east, the sun appears to rise in the east and set in the west, which creates the cycle of day and night.

For the question "Roughly how many times does Earth rotate during each complete revolution?", you need to know the relationship between Earth's rotation and its revolution around the sun. Earth takes approximately 24 hours to complete one rotation, which means it rotates about 360 degrees during each revolution.

To answer the question "How do Saturn's periods of rotation and revolution compare to Earth's?", you need to compare the lengths of Saturn's day (10 hours) and the time it takes for Saturn to complete one revolution around the sun (about 30 years) with Earth's periods. In this case, Earth's period of rotation is longer than Saturn's, while Earth's period of revolution is shorter.

To answer the question "Why does the sun appear to move westward across the sky during the day?", you need to understand the relationship between Earth's rotation and the apparent motion of the sun. The sun appears to move westward across the sky during the day because of Earth's eastward rotation.

For the question "Which of the following statements best describes the biosphere?", you need to choose the option that describes the biosphere, which is the part of Earth that contains living organisms.

To answer the question "What is the importance of water on Earth?", you need to understand the significance of water. The correct answer is that water allows life to exist on Earth.

For the question "Which of the following is an example of a constructive force?", you need to identify the option that describes an activity that builds or creates something. In this case, a volcano eruption is an example of a constructive force.

To answer the question "How does gravity affect the moon?", you need to understand the role of gravity in the relationship between the moon and Earth. Gravity pulls the moon towards Earth and keeps it from colliding with the sun.

1. wrong wrong wrong !!!!

2. Right, like 365

3. Right

4. Right, so go back and do 1.

5. Right

6. Right

7. Right, creates Hawaii :)

8. Ah come on, force toward center of earth is balanced by moon mass times centripetal acceleration resulting in circular orbit around earth
