In space, objects are weightless and float freely through the air. On Earth, objects have weight and are held to the ground. Which of the following is responsible for this difference between Earth and space?

• Earth's magnetism attracts objects to the ground, and space's magnetism repels objects from each other.

• Earth's gravity acts on all objects this way, and space does not have gravity.

• Earth's electricity acts on all objects this way, and space does not have electricity.

• Earth's temperature causes all objects to become heavier on Earth than they would be in space.

Cabinets are a good place to keep food. To keep the cabinets closed so bugs cannot get in, some cabinets have magnets inside of their doors. The magnets on a cabinet door keep bugs out because the magnets —

• pull toward each other to make loud crashing noises that scare the bugs

• pull toward each other to keep the door closed so bugs cannot get in the cabinet.

• push away from each other to make a force that stops the bugs from moving.

• push away from each other to push bugs out as they try to get into the cabinet.
