d. nested spheres
eventually philosophers decided that the lowest point in the cosmos was the center of the cosmos and that everything was attracted to that point. but, denser objects push lighter ones out of the way. what phenomenon did this not explain?
a. the earth is a sphere.
b. the earth and the things on it are layered.
c. there are volcanoes some places on earth but not in others.
d. the oceans sit on the earth without falling over the edge.

1.  c. eccentric epicycles

2. d. The oceans sit on the Earth without falling over the edge.

Explanation:

1.

In Ptolemaic model is used to study the apparent motion of planets in direct way ,  by assuming that each and every planet moves on a small sphere or circle , known as the epicycle . And each planet is moved by a system of two spheres one is epicylce and other is different , the center of different circle is called eccentrics . Nested spheres are also present in the Ptolemy's model.

2.

The oceans sit on the Earth without falling over the edge is the correct answer. If all the heavy density objects are pushing lighter objects away then the Earth itself would have thrown away the oceans out of its reach.
