Understanding Atmospheric Science Concepts

Why does Earth's atmosphere make life possible?

• It provides sunlight for energy.

• It shields Earth from harmful solar radiation and provides gases needed for life.

• It creates wind for weather patterns.

• It is where clouds are formed.

What causes air to exert pressure?

• The rotation of the Earth.

• The force of gravity on ocean currents.

• The movement of the Earth’s crust.

• The weight of air molecules above a surface.

Which two measurements are needed to calculate density?

• Weight and height

• Temperature and volume

• Volume and mass

• Mass and weight

Why do people get out of breath more easily at high altitudes?

• The air pressure is higher at higher altitudes.

• The air is warmer, causing difficulty breathing.

• The air is thinner, with fewer oxygen molecules.

• There is more carbon dioxide in the air.

What does the ozone layer protect Earth from?

• Greenhouse gases

• Acid rain

• Ultraviolet (UV) radiation

• Extreme temperatures

What is the largest source of air pollution?

• Volcanic eruptions

• Burning of fossil fuels by humans

• Natural forest fires

• Dust from deserts
