Atmosphere Overview

What are the five layers of the atmosphere in order from closest to farthest from Earth?

What gases make up the majority of Earth's atmosphere?

• Nitrogen and Oxygen

• Carbon dioxide and Oxygen

• Nitrogen and Hydrogen

• Oxygen and Argon

Explain the greenhouse effect and its impact on global warming.

• The greenhouse effect is a myth.

• Human activities have intensified this effect, causing global warming.

• The greenhouse effect is a natural process where certain gases in the Earth's atmosphere trap heat from the sun, leading to warming of the planet.

• The greenhouse effect is caused by excessive use of air conditioning

What is the ozone layer and why is it important?

• The ozone layer allows the sun rays to reach towards the planet Earth.

• The ozone layer is a type of cloud that blocks sunlight from reaching the Earth.

• The ozone layer is a layer of ice in the atmosphere that helps cool the Earth.

• The ozone layer is important because it absorbs the majority of the sun's harmful ultraviolet radiation, protecting life on Earth.

How does air pollution affect human health and the environment?

• Air pollution affects human health by causing respiratory diseases and cardiovascular issues.

• Air pollution harms the environment through global warming, acid rain, and ecosystem damage.

• Air pollution only affects plants, not humans

• Air pollution actually improves human health and the environment

Describe the concept of climate change and its causes.

What is the nitrogen cycle and why is it important for living organisms?

• The nitrogen cycle is a process that involves the circulation of oxygen in the atmosphere.

• Living organisms do not rely on the nitrogen cycle for survival.

• The nitrogen cycle is important for living organisms because it recycles nitrogen in a usable form throughout ecosystems.

• Nitrogen is only important for plants and not other living organisms.

The carbon cycle involves processes such as

• photosynthesis, respiration, decomposition, and combustion

• photosynthesis, digestion, decomposition, and combustion

• photosynthesis, respiration, combination of CO2, and combustion

• photosynthesis, respiration, carbon fixation, exposure to atmosphere

Nitrification process is done with the help of __________ bacteria

Incomplete combustion leads to the formation of __________ in the air.
