Yes or No

Old-earth scientists believe that the early earth had no free oxygen in its atmosphere.

Yes or No

The atmosphere is not clearly mentioned in the Genesis Creation account.

Yes or No

If an atmosphere with 21% oxygen is good for us, then an atmosphere with 100% oxygen would be much better.

Yes or No

The percentages of gases in the homosphere remain relatively constant.

Yes or No

Except for the homosphere, which is mixed by weather activity, the gases in the rest of the atmosphere separate out into layers that are ordered by the number of atoms in their molecules.

Yes or No

Since warm air rises,  the troposphere is the coolest layer of the atmosphere.

Yes or No

The troposphere is the only atmospheric layer to have winds.

Yes or No

The colors of the auroras depend on which composition layer of the atmosphere the auroras form in.

Yes or No

Ammonia is a compound that contains nitrogen.

Yes or No

Lightening is a natural source of fixed nitrogen.

Yes or No

The ozone layer protects life on Earth from dangerous radio waves from the sun.

Yes or No

Atmospheric scientists have determined that halting the global reproduction of CFCs 20 years ago has definitely begun shrinking the ozone hole over Antarctica.

Yes or No

Auroras occur when charged particles escape from the ionosphere into the magnetosphere.

Yes or No

The discovery of radiation belts surrounding the earth in 1958 was completely unexpected.

Yes or No

Most of the Sun's energy makes it to the earth's surface.

Yes or No

Infrared rays are a form of thermal radiation.

Yes or No

A thermal convection current in the atmosphere is a kind of density current.

Yes or No

Exposure to any kind of ultraviolet light in any amount is dangerous and should be avoided.

Which of the following gases was not present in the earth's earliest atmosphere according to naturalistic scientists?

-helium

-hydrogen
