I believe that the answer is C
Answer: Earthquake refers to the sudden shaking of the earth due to the release of energy by the seismic ways in the earth's interior. An earthquake of magnitude 2 is exactly ten times bigger, as well as about 31-33 times stronger than that of magnitude 1 .
Richter scale is used to measure magnitude of an earthquake, that means how much energy has been released due to the release of seismic waves.

It absorbs solar ultraviolet radiation, which heats the stratosphere. It also absorbs infrared radiation emitted by the Earth's surface, effectively trapping heat in the troposphere. Therefore, the climate impact of changes in ozone concentrations varies with the altitude at which these ozone changes occur.

Answer: about half the mass and a million times higher density.
The closest answer is B
Explanation:
A white dwarf is what remains of a star after it uses up its nuclear fuel. Before a white dwarf is formed, it discards the external layer and retains its hot center. This center can be as hot as a hundred thousand Kelvin which then takes tens of millions of years to cool down. White dwarfs are very dense, an Earth-sized white dwarf has a density of a billion kg/
. In comparison to the sun, it is about half the mass and a million times denser.
