IS 1: Earth, Moon, and Universe Formation

What is the most widely accepted theory about the origin of the Moon?

• The Moon was captured by Earth's gravity

• The Moon was formed from a giant impact between Earth and a Mars-sized body

• The Moon was formed simultaneously with Earth

• The Moon was created from a supernova explosion

What does the Big Bang theory explain?

• The explosion of a massive star

Why is the detection of red light proof of the expanding universe?

• Red light is longer and more stretched than other light waves.

• Red light is shorter and more condensed than other light waves.

• Red light has more energy compared to other light waves.

• Red light is comprised of more waves than of other types.

What happens when the mass of gravity is greater than that of the energy of expansion of a universe?

• The universe will continue to expand.

• The universe will slow down expanding and will halt to a stop.

• The universe will start to contract (The Big Crunch).

• The universe will release immense amounts of energy (The Big Bang).

Which of the following best describes the early formation of the earth?

• particles accumulated and gravity attracted more gaseous matter forming planetesimals

• earth was formed elsewhere and was captured by the sun's gravity

• two planets the size of venus collided forming a single planetary body

Which of the following DOES NOT describe the early earth?
