Thermosphere
What is the outermost layer of the atmosphere that contains electrically charged particles that are called ions and reflects radio waves?
Thermosphere
What is the color that absorbs all light?
Black
What contributes to the increasing amount of carbon dioxide in the air?
Burning fossil fuels

What is the term for the energy from the Earth that is released back into space?
Outward flow
What is the layer that extends to 30 miles up, there is very little wind and it is very cold - - Planes fly in this layer?
Stratosphere
What is the following:
Volume of a given amount of gas held at a constant temperature varies inversely with the applied pressure when the temperature and mass are constant.
Boyle’s law
What is the term for when light energy strikes objects some surfaces absorb it and heat up and some reflect it?
Reflectivity
