You are given a passage. You need to construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) its answer is the whole paragraph. Avoid creating questions that can be answered correctly without actually understanding the paragraph.

The Earth is round because it is a large body, and gravity tends to make large bodies round because that is the gravitational efficient configuration for the matter to be in.

There are a few reasons you can encounter non-round bodies in space:

1) the object is small (for example asteroids), so it's gravity has less say proportionally on the shape

2) It has experienced a catastrophic collision with a large body

3) It is under very strong rotational or tidal forces

4) It is expelling matter/energy in the form of cosmic jets, nova ejecta, etc.
why is the earth round?
