For about how many years do astronomers believe the solar system has existed

For about 4.6 billion years.

In which layer of the sun is a huge supply of energy produced

in the core

Why can scientists not accurately predict where an earthquake will occur

They cannot determine which point along a fault has the most pressure.

On the Richter scale an earthquake measuring 2 is ten times stronger than one measuring 3

No, it is the other way round - higher numbers indicate a stronger earthquake. The factor 10 is correct, though.
