Due to tidal forces, a moon orbiting a planet will eventually
a
always keep the same side toward the planet
b
collide with the planet
c
break up into a number of fragments
d
develop a warmer climate as time goes on
Jupiter's moon Io is very volcanically active, which means it has plate tectonics.
a.
true
b.
false
When tidal bulges are NOT in a direct Earth-moon line but slightly ahead of the moon,
a.
Earth’s gravity weakens.
b.
their gravitational field pulls the moon forward in its orbit, causing it to recede from Earth.
c.
their gravitational field pulls the moon back in its orbit, causing the moon to fall toward Earth.
d.
Earth’s gravity strengthens, causing the moon to orbit faster.
e.
the tidal bulges have no effect on the moon.
1. The tides are present on earth because...
A) the sun causes the earth to orbit
B) the moon has a negligible gravitational effect on the earth except for in the oceans
C) there is a different force of gravity acting on either side of the earth resulting from the moon
D) tectonic plates shift as the earth rotates causing the water levels to vary.
