Your volume is ...

• How much matter you have.

• How heavy you are.

• How many atoms or molecules you have in your body.

• How much space you take up.

Answer explanation

How much space something occupies is its volume, and it's not the same as its mass.

If the Earth had the same volume (size) but more mass, gravity would be....

• Stronger

• Weaker

• The same

• No way to tell

Answer explanation

Gravity exists because the Earth has mass. All objects with mass attract each other with gravity.

If the Earth had the same mass but more volume, gravity would be....

• Stronger

• Weaker

• The same

• No way to tell

If you were go travel to the moon, your weight would....

• Get bigger, because the moon has less mass than the earth

• Get smaller, because the moon has less mass than the earth

• Stay the same, because your weight doesn't depend on gravity

• Stay the same, because there's no air on the moon

Answer explanation

Remember, it's mass that causes gravity. The moon has less mass than the Earth, so its gravity is weaker, and it pulls you with less force.

Therefore, you would weigh less on the moon.

If you were to travel to the top of the tallest mountain, your weight would....

• get smaller, because there's less air pressure

• get bigger, because there's less air pressure

• get smaller, because you're farther from the Earth's center

• get bigger, because you're farther from the Earth's center

Answer explanation

The farther you are from the Earth's center, the weaker gravity is, so it will pull you with less force.

Therefore, you will weigh less.

If you were to travel to the top of the tallest mountain, your mass would....

• stay the same, because your mass does not depend on gravity

• stay the same, because you're still on earth

• get smaller, because you're farther from the Earth's center

• get bigger, because you're farther from the Earth's center

Answer explanation

Your mass is a property of you! It doesn't depend on graviy.
