The diagram below shows different layers of sedimentary rocks.

picture showing seven layers of rocks of different colors labeled a, b, c, d, e, f, and g from top to bottom; a and b are parallel horizontal layers at the top of the diagram and c, d, e, f, and g are slanted layers with c closest to the surface and g at the bottom.

based on the diagram, which of these inferences is most likely correct?

a. layer a is older than layer b.
b. layer c is older than layer e.
c. layer f is younger than layer d.
d. layer b is younger than layer g.

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
