What is the source of almost all the energy in our solar system?
a. plant life

Which is the more reliable method for a sailor to determine north: using the star Polaris or reading a map? Why?
Using the star Polaris is more reliable because its position stays fixed above the North Pole. With a map, you would need to find landmarks to know which direction is north.

a. asteroids
b. comets
c. gas giants
c. gas giants
Planets that are close to the sun ________________.
a. move through the asteroid belt
b. orbit faster than the outer planets
c. orbit slower than the outer planets
d. move closer and closer to the sun
Besides the fact that space probes can travel to places that may be dangerous for people, what are some other advantages of sending a space probe instead of a crewed mission to gather data?
Space probes can operate over long distances and time. A crewed mission is limited because it needs food, water, and an oxygen supply.
