LQ 14

Which of these worlds is the most active geologically?

Venus

One of the best proofs that our theory of how the solar system formed is correct is that astronomers now observe

disks around other stars which show evidence of gaps where planets may be forming

The Murchison meteorite that was found in Australia in 1969 is important to scientists because it contained

organic materials, such as amino acids

One way to find a new meteorite is to:

search the area beneath or close to the point where a bright fireball was seen to burn out

The reason that Olympus Mons, the tallest mountain on Mars, is taller than Mount Everest (the tallest mountain on Earth) is that (choose all that apply):

the gravity on Mars is less, so a larger mass can support itself against its own weight; there are no continental plates that move sideways on Mars, while there are such sliding motions on Earth

The ages of stony meteorites have been measured to be roughly equal to:

the oldest ages we have measured for any bodies in the solar system
