Why are the lunar mountains smooth and rounded rather than having sharp, pointed peaks?
A. Because a sheet of ice once covered the moon’s surface billions of years ago.
B. Because they rose up from beneath the Moon’s surface due to an increase in pressure from its hot core billions of years ago
C. Because micro meteorites impacts have caused their gradual erosion
D. Because the moon once had sulfuric acid clouds long ago
2. Supposed that you are weighing 54kg, what is your weight provided that you are in the surface of the moon? You are in the surface of the earth? Hint: gearth = 9.81m/s2
and gmoon = 1/6 of gearth
Kindly include figure, analysis and findings.
That the moon has no magnetic field implies that
a.
the moon is spinning too slowly to produce a magnetic field.
b.
the interior of the moon is too hot to produce a magnetic field.
c.
the crust of the moon is so thick that the magnetic field can not get out of the interior.
d.
the moon’s core contains little if any molten iron.
e.
the moon is moving further from Earth.
