Which sentence about galaxies provides evidence of universe expansion that supports the Big Bang Theory?(1 point) Responses Galaxies are moving at different speeds and in different directions. Galaxies are moving at different speeds and in different directions. Galaxies are in constant motion. Galaxies are in constant motion. Galaxies are moving more slowly than they have in the past. Galaxies are moving more slowly than they have in the past. Galaxies are moving away from each other.

Galaxies are moving away from each other.

The sentence that provides evidence of universe expansion that supports the Big Bang Theory is: "Galaxies are moving away from each other." This sentence indicates that the distance between galaxies is increasing over time, suggesting that the universe is expanding. The observation that galaxies are moving away from each other was one of the key pieces of evidence that led to the development of the Big Bang Theory. This evidence is based on the redshift observed in the light from distant galaxies, which indicates that they are moving away from us and from each other.

Which provides evidence of universe expansion that supports the Big Bang Theory? Select the three correct answers.(2 points) Responses The temperature of the universe is increasing. The temperature of the universe is increasing. Galaxies are moving away from each other. Galaxies are moving away from each other. An enormous amount of weak cosmic background radiation has been detected in the universe. An enormous amount of weak cosmic background radiation has been detected in the universe. The temperature of the universe is decreasing. The temperature of the universe is decreasing. The temperature of Cosmic Microwave Background radiation varies widely from one part of the universe to another. The temperature of Cosmic Microwave Background radiation varies widely from one part of the universe to another. The universe is undergoing a cycle of contraction and expansion.

The three correct answers are:

- Galaxies are moving away from each other.
- An enormous amount of weak cosmic background radiation has been detected in the universe.
- The temperature of the Cosmic Microwave Background radiation varies widely from one part of the universe to another.

The sentence that provides evidence of universe expansion that supports the Big Bang Theory is "Galaxies are moving away from each other."

Which is evidence of universe expansion that supports the Big Bang Theory?(1 point) Responses The temperature of the universe is the same as it was at the time of the Big Bang. The temperature of the universe is the same as it was at the time of the Big Bang. The temperature of the universe has cooled and warmed repeatedly over time. The temperature of the universe has cooled and warmed repeatedly over time. The temperature of the universe has warmed over time. The temperature of the universe has warmed over time. The temperature of the universe has cooled over time.

The sentence that provides evidence of universe expansion that supports the Big Bang Theory is: "The temperature of the universe has cooled over time." According to the Big Bang Theory, the universe started from an extremely hot and dense state and has been expanding and cooling ever since. This cooling of the universe is one of the key pieces of evidence supporting the theory.
