What way is using a compass better than using stars to find directions?
A compass can work at all times. You can't see stars during the day. Even at night, there needs to be at least fairly clear skies to enable you to see stars and work out your direction. A compass can be easier to use. You need a knowledge of the stars, which you don't need with a compass. A compass should work anywhere. The night sky looks different on different parts of the planet which can be confusing.

Why is north not straight up?
North is used as a direction, like left or right. not up or down. In truth, the north pole is not really "above" us. this is simply because "up" a direction that is used to describe the direction away from the earth and into the sky no matter where you are on any planet. Up is relative, but north, south, east, and west are the same everywhere. To sum it up, Anywhere north of you isn't in the sky because it's not up, but the clouds are up because they are in the sky. If they were any direction on the compass, the would completely surround us every day.
