.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

Kuiper belt
Observations of distant type Ia supernovae indicate that the expansion of the universe is speeding up with time - not slowing down! So there must be a force causing this.
