Atmosphere, Air Pressure, Pollution Ch 12

Front

What is the main cause of air pollution?

Back

Burning fossil fuels is the primary cause of air pollution, releasing harmful substances into the atmosphere.

Front

What are VOCs?

Back

VOCs, or Volatile Organic Compounds, are hydrocarbons that vaporize easily, found in products like gasoline, solvents, and paints.

Front

In which layer of the atmosphere does all weather take place?

Back

All weather occurs in the troposphere, the lowest layer of the atmosphere.

Front

Which layer of the atmosphere is the coldest and does not absorb radiation from the sun?

Back

The mesosphere is the coldest layer of the atmosphere and does not absorb solar radiation.

Front

What are zero emissions vehicles?

Back

Zero emissions vehicles are vehicles that produce no emissions from tailpipes or gasoline.

Front

What is air pressure?

Back

Air pressure is the force exerted by the weight of air above a given point, measured in units like pascals or millibars.

Front

How does altitude affect air pressure?

Back

As altitude increases, air pressure decreases because there is less air above a given point.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.

Front

What are the primary greenhouse gases?

Back

The primary greenhouse gases include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

Front

What is the role of the ozone layer?

Back

The ozone layer protects life on Earth by absorbing the majority of the sun's harmful ultraviolet (UV) radiation.
