Question 1

What is the status of the greenhouse effect on Mars at the present time?

Accepted Answer

A)  It no longer exists at all. 
B)  It is very weak and raises the planet's temperature only a few degrees above the temperature it would have with no atmosphere at all. 
C)  It is weak but becoming stronger as Martian volcanoes continue to dump large amounts of CO2 into the atmosphere. 
D)  It is very strong and has caused the temperature to be at least 100 degrees above the temperature it would have been with no atmosphere at all.

Accepted Answer

A)  Only as atmospheric water vapor,never condensing as liquid water or solid ice 
B)  As a liquid,flowing continuously along the numerous flood valleys and meandering stream beds 
C)  As permafrost,polar icecaps,and atmospheric vapor 
D)  As a liquid in lakes and rivers

B)  Europa. 
C)  Ganymede. 
D)  Enceladus. 
A)  Mercury. 
B)  Europa. 
C)  Ganymede.

Question 4

The huge volcano Olympus Mons on Mars and those that make up the Hawaiian Islands on Earth appear to be very similar,but they differ in one important respect.What is this difference?

Accepted Answer

A)  Olympus Mons is very close to the Martian north pole,where tidal stress from the Sun is small,whereas the Hawaiian Islands are close to the equator,where tidal stresses from the Moon and Sun have formed the fault along which they lie. 
B)  Olympus Mons is formed almost solely of sulfur,whereas the Hawaiian Islands are formed of rock from the solidification of lava. 
C)  Olympus Mons is a very steep-sided volcano,whereas the volcanoes of Hawaii are rather flat,with gentle slopes right up to their calderas. 
D)  In the Hawaiian Islands,plate tectonic motion has moved the Pacific Ocean floor over a hot spot,forming a line of volcanoes.No such motion occurred for Olympus Mons over an equivalent hot spot on Mars.

Question 5

Which of the following objects in the solar system has the smoothest surface relative to its radius?

Accepted Answer

A)  Io,the volcanic moon of Jupiter,whose surface is continuously coated with volcanic material 
B)  Earth,with its oceans and molten interior that both allow readjustment of the surface 
C)  Mercury,in view of the intense solar radiation that has melted and smoothed the surface 
D)  Europa,a moon of Jupiter coated with water ice

Question 6

A shield volcano is a

Accepted Answer

A)  volcanic dome on the side of a larger volcano that shields the surrounding plains from inundation by lava from the main vent. 
B)  very broad volcano with gently sloping sides,similar in shape to an ancient Greek shield. 
C)  tall volcano with steep sides,similar in shape to the central ornament of an ancient Roman shield. 
D)  vast lava flood-plain originating from a ground-level fissure,similar in size and topography to the Canadian Shield rock formation.
