One way that scientists figure out what was occuring in ancient times is by looking at the types of sedimentary rock that has formed. If an area has sedimentary rocks formed entirely from fine clay particles, that shows that: 1 The rock formed in a place like the middle of a lake bed where water that had been moving faster became very slow.

2 The rock formed in an area with fast moving water that carried away all of the larger particles.

3 The rock must have formed during a volcanic eruption.

4 the rock was found at the bottom off a cliff that dropped a lots of different sized particles

the correct choice is a .

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
