revolution of Earth around the Sun
Earth’s elliptical orbit in space
moon’s orbit around Earth
The movement causes day and night on Earth is the rotation of Earth.
The rotation is the spinning around of an object about its own axis passing through the center.
When the Earth rotates about its own axis, the rotation completes in 24 hours. This causes the day to night and night to day. When the part of Earth is in front of Sun, there is day. But, when the same part of Earth goes away from the Sun, the sunset occurs and then eventually night occurs.
Thus, the movement causes day and night on Earth is the rotation of Earth.

The movement that causes day and night on Earth is the rotation of the earth on its axis, which is in option a as the earth rotates from west to east, completing one full rotation in approximately 24 hours.
As the Earth rotates, the side facing the sun experiences daylight, while the opposite side facing away from the sun experiences nighttime. This rotation creates the cycle of day and night that we observe on Earth. The other movements mentioned, such as the revolution of Earth around the Sun, Earth's elliptical orbit in space, and the moon's orbit around Earth, are not directly responsible for causing day and night.

B.) the universe may continue to expand
C.) stars could burn out , causing the universe to become dark and cold
D.) gravity could pull galaxies back together causing a reverse of the Big Bang
Answer:
B.) the universe may continue to expand
Explanation:
The steady state theory which states that the universe was, is and will be the same, has been discredited by two physicists who found the leftover energy from the big bang.
If you are listening to FM radio, you might have heard some static noise while changing stations, that noise is from the leftover energy from the big bang. This energy is called the dark energy.
The dark energy tries to rip everything apart while gravity tries to hold everything together.
It was observed that the dark energy is stronger than gravity.
The distance between the galaxies is increasing. This proves that the dark energy successfully defeated the gravity and expanted two massive objects in the universe.
Because of this dark energy the universe will continue to expand.
Note: Dark energy is also increasing the distance between protons in atomic nucleus in every atom in our body too. Chilly right?
the answer is B! it would continue to expand.....just took the test XD
a. Jupiter is farther from the sun so the force of gravity on it is weaker.
b. A great deal of Jupiter’s volume is in the gas phase.
c. Most of Jupiter's mass is found in its rings and moons.
d. Jupiter’s internal heat serves as an outward force which counters gravity.
Answer:
A great deal of Jupiter’s volume is in the gas phase.
explaination???:
as we all know gas is less dense than solid, it would scatter more and u would see it bigger.
B.) occurs when an acid is dissolved in water
C.) occurs when a base is dissolved in water
d.) is a reaction between an acid and a base
A.
It remains constant.
B.
It decreases.
C.
It increases, then decreases.
D.
It increases.
