12.

How did the solar system form?

a)

Gravity caused gas and dust to contract. The majority collected in the center of the solar system creating the Sun, while smaller leftovers became the planets, moons, and other objects.

b)

The Sun’s gravity captured passing objects that grew into the planets, moons, and other objects

c)

A giant star slowly began to shed its outer layers which turned into the planets, moons, and other objects. The core was left behind to become our Sun.

Two giant stars collided and blew apart. The largest star’s core remained to become our Sun, while the rest of the material formed into the planets, moons, and other objects.

The maria are deposits of minerals that were once dissolved in the ocean water covering the Moon’s surface.

c)

The maria are the original rocks and minerals that existed on the Moon’s surface before all the impacts and craters occurred

d)

The maria are pyroclastic materials ejected from the Moon’s many volcanoes

16.

What is the most widely accepted model for the origin of the Moon?

a)

A planet like object smashed into the molten Earth. Parts of the Earth and the remaining bits of the small planet reformed into the Moon.

The Moon was thrown toward the center of the solar system by the outer planets. It was then captured by Earth’s gravity on the way by.

It formed as a small planet between Earth and Mars. Mars collided with it and knocked it into Earth’s orbit where it was captured by Earth’s gravity.

Both the Earth and Moon formed at the same time as a dual planet system. The Earth’s gravity pulled off the Moon’s atmosphere and water leaving it barren and dead.
