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.
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
365
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

It contains all of Earth’s water.
It is the part of Earth that contains living organisms.
2/2
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.

buildings collapse in an earthquake
river erosion within the Grand Canyon's rock walls
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.
what is the answer???
what is the answer
what’s the answer ?
give me a sec guys im doin it right now
Guys you forgot question 1
Answer is A
what are the answers
1. Earth's rotation causes day and night because as it rotates towards the east, the sun appears to rise in the east and set in the west. This is because as Earth rotates, different parts of the planet are exposed to the sun's light, creating daylight, while the other side experiences darkness, creating nighttime.
2. Earth rotates approximately 24 times during each complete revolution. This means that it takes about 24 hours for Earth to complete one full rotation on its axis.
3. In comparison to Earth, Saturn's periods of rotation and revolution are different. Saturn's day, or the time it takes for one full rotation on its axis, is roughly 10 hours, which is shorter than Earth's 24-hour day. However, Saturn's period of revolution, or the time it takes to complete one orbit around the sun, is about 30 years, which is much longer than Earth's 365-day revolution.
4. The sun appears to move westward across the sky during the day because Earth rotates towards the east. This rotation creates the illusion of the sun moving from east to west, even though it is actually the Earth's rotation causing this apparent motion.
5. The biosphere is best described as the part of Earth that contains living organisms. It is the sphere of the Earth where life exists, including plants, animals, and microorganisms. The biosphere includes all ecosystems, such as forests, oceans, deserts, and even human-made habitats.
6. Water on Earth is important for several reasons. It allows life to exist, as it is essential for the survival of all living organisms. Water also regulates temperature on Earth, helping to keep the top layer of the geosphere cool. Additionally, water plays a crucial role in various natural processes, such as the water cycle and nutrient transport.
7. A volcano eruption is an example of a constructive force. Constructive forces are processes that shape or build up the Earth's surface. In the case of a volcano eruption, it brings new lava and materials to the surface, creating new landforms.
8. Gravity affects the moon by pulling it towards Earth. Gravity is the force of attraction between objects with mass, and since the moon has mass, it experiences the gravitational pull from Earth. This gravitational force keeps the moon in its orbit around Earth and prevents it from colliding with the sun or moving in a straight line.
Thank you, Ms. Sue you made me go back and look at my material. Thank you again! :)
AND DONT LISTEN 2 MS. SUE SHE A FROD
AND IN OTHE QUESTIONS NO ONE EVER LIKED HER SOOOO IF YOU LIKE HER YOUR A LOOSER WITH HER.....!!!!!!!!
