Climate Change
What is one major cause of climate change?
Greenhouse effect, fossil fuels, waste decomposition, deforestation, and agriculture.
What is the ozone hole?
A big gap in the ozone layer of the Earth's atmosphere. This hole is slowly growing and reduces the layer's capacity to block harmful sunlight and protect the globe.
What gas causes Ocean Acidification?
CO2 or carbon dioxide
Water, air, soil, sound, thermal, light, radioactive, plastic, electronic waste.
What does biodiversity mean?
What is an effect of climate change on weather patterns?
What man-made chemical caused the ozone hole?
CFCs, or chlorofluorocarbons.
What happens to the pH level when CO2 increases in oceans?
pH decreases
What is the cause of nearly all types of pollution?
Human activity.
Name the one major cause of species extinction.
Habitat destruction.
Why is carbon dioxide considered a greenhouse gas?
Because it traps escaping heat from the Earth.
How does the ozone layer protect life on Earth?
It prevents harmful UV rays from reaching life on Earth. They help prevent skin cancer and eye cataracts in humans. It protects ecosystems and marine life too!
How does acidification affect marine life?
It harms animals with calcium carbonate shells, as these start to dissolve. It can also bleach coral!
Name some natural causes of air pollution.
Volcanic eruptions, dust, natural wildfires.
Why is biodiversity important for ecosystem health?
The more diverse an ecosystem, the more capable it is of staying healthy, functioning properly, and supporting life!
Name all greenhouse gases.
Carbon dioxide, water vapor, methane, nitrous oxide.
What was the agreement to ban CFCs?
The Montreal Protocol
Explain a link between climate change and ocean acidification?
Climate change is caused by a rise in greenhouse gases, like CO2. Ocean acidification is caused by an increase in CO2!
Name two types of invisible pollution.
Sound, light, radioactive, thermal.
Explain how loss of biodiversity can affect humans.
It reduces resources like food, medicine, and materials. It can also harm tourism, agriculture, and health.
How does agriculture and farmers contribute to climate change/global running?
Farmers use tractors and vehicles that produce smoke and carbon dioxide. The pesticides farmers use contain nitrous oxide, and when used in excess it goes into the atmosphere.
Name one difference between Ozone Depletion and Climate Change?
Climate change is a change in temperature (rising) of the Earth, while Ozone depletion is a loss of a layer in the Earth's atmosphere.
How does carbonic acid form?
Water + CO2
Explain how pollution can harm the environment.
It harms natural habitats and makes them dirty! These unclean environments makes it hard for animals to live their and can make them sick or injured.
What is an endangered species?
A species that is close to going extinct and in few numbers.
