Question 1

Accepted Answer

A) True 
 B)False  True

Question 2

Why might a moon's orbit be used to evaluate if it was a primary moon,formed at the same time as the planet or a feature (asteroid or comet)that was captured by the planet's gravity?

Accepted Answer

Because all of the planets rotate in approximately a common plane,the ecliptic,moons that also revolve around their planet are also likely to have formed at the same time as the planet,from the solar nebular,whereas objects with strongly elliptical orbits or orbits far off the plane of the ecliptic are likely to be capture objects

Question 14

Venus has dense clouds and thick atmosphere,yet there is no evidence for water on the surface.Why?

Accepted Answer

A) It is hard to know because the clouds obscure the surface and only a few probes have survived landing. 
B) Water could not survive as liquid water on the surface because it is too hot. 
C) The water has all been taken up in minerals on the surface due to weather long ago because of high chemical weathering rates. 
D) The water is bound up as sulfuric acids and other acids in the atmosphere. 
A) It is hard to know because the clouds obscure the surface and only a few probes have survived landing.

Jupiter's moon Io is thought to be the volcanically active world in our solar system.What is the inferred source of heat?

Accepted Answer

A) Very high abundances of radioactive elements have been detected on the planet. 
B) Io has a strong magnetic field as does Jupiter,so as Io moves through Jupiter's magnetic field,large electrical currents are generated,which heat the planet.
