All of the following statements describe sedimentary rocks EXCEPT-

• It is created by extreme heat and pressure

• They are rocks made of smaller rock pieces

• they are created through deposition, compaction and cementation

• They are created by sediment being stuck together

Why does Jupiter have more moons than the other planets?

• Jupiter has the most gravitational pull out of all the planets due to it's mass being so large.

• Jupiter's moons were created from the dust and debris of a nearby comet that passed by.

• Jupiter's moons are made up of different materials than the other planets, giving them more stability.

• Jupiter has a greater magnetic field than the other planets, which attracts more moons to its orbit.

What would happen to the Earth if the Sun no longer had enough gravity to keep it in its orbit?

• The Earth would move in a straight line because there is no gravitational pull holding it in place.

• The Earth would be pulled into a black hole

• The Earth would be destroyed by asteroids

• The Earth would be pushed away from the Sun and into deep space
