Air pollution, ozone layer, weather

What is air pollution?

• The emission of pleasant scents into the air that can improve the environment and human health.

• The presence of harmless substances in the air that have no effect on the environment or human health.

• The process of purifying the air to remove all pollutants and contaminants.

• The presence of harmful substances in the air that can negatively affect the environment and human health.

What are the main sources of air pollution?

• Industrial emissions, vehicle exhaust, burning of fossil fuels, and agricultural activities

• Dust particles, pollen, and volcanic eruptions

• Household cleaning products, cooking fumes, and indoor smoking

• Rainfall, wind, and natural vegetation

What is the ozone layer?

• The ozone layer is a layer of the Earth's atmosphere that contains a high concentration of oxygen molecules.

• The ozone layer is a layer of the Earth's atmosphere that protects us from harmful ultraviolet radiation.

• The ozone layer is a region of the Earth's stratosphere that contains a high concentration of carbon dioxide molecules.

• The ozone layer is a region of the Earth's stratosphere that contains a high concentration of ozone molecules.

What causes the depletion of the ozone layer?

• Deforestation

• Air pollution

• Greenhouse gases

• Ozone-depleting substances (ODS)

What are the effects of air pollution?

• Air pollution has various effects on human health and the environment.

• Air pollution has positive effects on human health and the environment.

• Air pollution only affects the environment, not human health.

• Air pollution has no effects on human health and the environment.

What factors influence weather patterns?

• Moon phases, ocean currents, and solar radiation

• Geographical location, time of day, and cloud cover

• Population density, vegetation, and altitude

• Temperature, air pressure, humidity, wind speed and direction, and atmospheric conditions

Define Weather ?

• It is what the air is like outside at a certain time or place. Example, sunny; rainy; windy.

• It is what happens when a caterpillar becomes a butterfly.

Define Climate?

• Weather averaged over a long period of time

• Weather averaged over a short period of time

Why is the ozone layer vital to life on Earth?

• Planes fly in the ozone layer

• It is made up of oxygen (O₂)

• It shields the Earth from ultraviolet (UV) rays from the sun

• It causes clouds to be created

Possible human solutions for limiting global warming and climate change are...

• being more energy-efficient

• using renewable sources of energy

• removing carbon from fossil fuel emissions

• all of the above
