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.***
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**
because Earth rotates to the west
because the sun moves in a westerly direction
because of the way you are looking into the sky

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.****
It provides ice at the poles.
It creates Earth’s blue color from space.

weathering of a mountain due to rain
a volcano eruption****
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.
all correct. Your teacher is too easy.
Based on the answer options provided, here is the feedback for each question:
1. How does Earth’s rotation cause day and night? (Answer: B)
Correct! As Earth rotates toward the east, the sun appears to rise in the east and set in the west, causing day and night.
2. Roughly how many times does Earth rotate during each complete revolution? (Answer: D)
Correct! Earth rotates approximately 365 times during each complete revolution around the sun, corresponding to the duration of a year.
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? (Answer: Earth's period of rotation is longer; Earth's period of revolution is shorter.)
Correct! Saturn's period of rotation (10 hours) is shorter than Earth's, but its period of revolution (30 years) is longer than Earth's.
4. Why does the sun appear to move westward across the sky during the day? (Answer: because Earth rotates to the east)
Correct! The sun appears to move westward across the sky because Earth rotates from west to east.
5. Which of the following statements best describes the biosphere? (Answer: It is the part of Earth that contains living organisms.)
Correct! The biosphere refers to the part of Earth that contains all living organisms, including plants, animals, and microorganisms.
6. What is the importance of water on Earth? (Answer: It allows life to exist.)
Correct! Water is essential for life to exist on Earth. It supports various ecosystems, provides habitats, and is crucial for the survival of living organisms.
7. Which of the following is an example of a constructive force? (Answer: a volcano eruption)
Correct! A volcano eruption is an example of a constructive force as it creates new landforms and deposits materials that can eventually lead to the formation of new habitats.
8. How does gravity affect the moon? (Answer: It pulls the moon toward Earth.)
Correct! Gravity pulls the moon toward Earth, causing it to orbit around our planet in a curved path.
Well done! Your answers are all correct.
