Frage 1
Frage
In comparison to the planets in the solar system Mercury is:
Frage 2
Frage
Mercury is roughly the size of the Moon, though, slightly larger.
Frage 3
Frage
Mercury has not yet been explored by any space probes.
Frage 4
Frage
Describe Mercury's interior.
Antworten
-
Mercury has a large, semi-molten, iron-nickel core, a silicate mantle, and a thin, rocky crust.
-
Mercury has a small, solid iron-nickel core, a larger liquid outer core, a silicate mantle, and a rocky crust.
-
Mercury has a large, solid, iron-nickel core, a rocky mantle, and a rocky crust.
-
Mercury has a small, semi-molten, iron-nickel core, a large silicate mantle, and a thin rocky crust.
Frage 5
Frage
What is unique about Mercury's rotation?
Antworten
-
Mercury rotates backwards on its axis (clockwise) whereas all the other planets rotate counterclockwise.
-
Mercury "wobbles" as it rotates on its axis.
-
Mercury's axis is at a 90 degree angle, so it rotates on its side.
-
Mercury's rotation is experiencing tidal lock, which causing the same side of Mercury to face the Sun at all times.
Frage 6
Frage
1 year (the amount of time it takes Mercury to orbit the sun) on Mercury is shorter than 1 day (the time it takes to rotate once on Mercury's axis) on Mercury.
Frage 7
Frage
Mercury has no magnetic field.
Frage 8
Frage
What is unique about Mercury's orbit?
Antworten
-
It is the most elliptical orbit of any planet in our solar system.
-
It is the most circular orbit of any planet in our solar system.
-
It is perpendicular in comparison to other planets' orbits.
-
Mercury orbits backwards around the Sun, so it moves in a clockwise path.
Frage 9
Frage
Why does Mercury experience extreme temperature changes?
Antworten
-
Because it has no atmosphere to retain heat.
-
Because of Mercury's closeness to the Sun.
-
Because of Mercury's slow rotation causing long days and nights.
-
All of the above
Frage 10
Frage
Why does Mercury lack an atmosphere?
Antworten
-
Mercury lacks an atmosphere due to its small gravitational force.
-
Mercury lacks an atmosphere because the Sun burns off all gas before it can create an atmosphere.
-
Mercury lacks an atmosphere because it does not have a magnetic field to protect its atmosphere from the Sun.
-
Mercury lacks an atmosphere because it never developed one.
Frage 11
Frage
What evidence suggest that Mercury may have a partially molten, or molten interior?
Antworten
-
The presence of a magnetic field.
-
The odd "wobbling" of Mercury's rotation on its axis.
-
The high surface temperature indicates that there must be a partially-molten interior.
-
A and B are both correct.
-
A, B, and C are all correct.
-
A and C are correct.
Frage 12
Frage
While Mercury currently has a slow rotation, it probably rotated much faster in the past.
