which statements best describe earths atmosphere?
□ it is one of the four elements from which all other substances are made.
□ it extends from earths surface to outer space
□ it contains gases and particles that surround earth.

Explanation:

• The four classical elements (earth, water, air, fire) are an ancient concept. Earth's atmosphere is not one of these in the modern scientific sense.
• The atmosphere does extend from Earth's surface outward (though not infinitely to "outer space" in a strict boundary - it gradually thins).
• By definition, the atmosphere is a layer of gases and particles surrounding Earth.

Answer:

• B. It extends from Earth's surface to outer space
• C. It contains gases and particles that surround Earth.
