The most abundant elemental gas in the atmosphere is...

• Nitrogen

• Oxygen

• Argon

• Carbon Dioxide

Answer explanation

* N has no odor, is tasteless, and colorless.

* Nitrogen gas (N2) makes up 78.1% of the Earth's atmosphere

* Atmosphere contains an estimated 4,000 trillion tons of N2

* Nitrogen is not a metal.

* Nitrogen gas is inert (doesn't react)

* Nitrogen is in all living things!

The second most abundant elemental gas in the atmosphere. (21%)

• Nitrogen

• Oxygen

• Argon

• Carbon Dioxide

Answer explanation

* Animals and plants require oxygen for respiration.

* Oxygen (O2) gas is colorless, odorless, and tasteless.

* Liquid and solid oxygen is pale blue.

* Without oxygen a fire cannot burn.

* Steels and other metals react slowly with Oxygen to form iron oxide or RUST!

Nitrogen and Oxygen make up 99% of Earth's atmosphere. What element makes up most of the other 1%?

• Nitrogen

• Oxygen

• Carbon

• Argon

Answer explanation

* Argon is a colorless, odorless gas at room temperature. When ionized, argon emits a distinctive violet glow.

* Argon is produced industrially by cryogenically distilling air.

* Argon only accounts for 0.94% by volume of the gasses in the atmosphere. Yet, it is the third most plentiful gas in air.

* Argon is used in fire-suppression systems. The argon displaces the oxygen in a room and combustion stops.

Which of the following make up the rest of the Earth's atmosphere after Nitrogen, Oxygen, and Argon?

• Carbon Dioxide

• Water Vapor

• Traces gases of other compounds and elements.

• Particles like dust.

What is a system?

• Parts that work together as a whole.

• A part of a machine.

• A beginning.

• The way something works.
