Climate Change Test

What is the main cause of current climate change?

• Natural volcanic activity

• Changes in Earth’s orbit

• Greenhouse gas emissions

• Solar flares

The greenhouse effect is an artificial process caused entirely by human activities, where gases like oxygen and nitrogen trap sunlight, rapidly heating the planet and leading to global climate stability.

• True

• False

What role does the greenhouse effect play in climate change?

• It prevents all heat from reaching Earth

• It cools the Earth's surface

• It traps heat

• It reflects sunlight back into space

Which gas is not a major contributor to the enhanced greenhouse effect?

• Methane

• Oxygen

• Carbon dioxide

• Nitrous oxide

Why are wildfires becoming more frequent and intense?

• Less rainfall during winter

• Decreased vegetation

• Colder temperatures

• Stronger winds and prolonged dry seasons

How does ocean acidification harm marine ecosystems?

• It makes water have a strong smell

• It reduces oxygen levels in the ocean

• It weakens organisms' shells

• It increases sea salinity

What is one consequence of rising sea levels due to climate change?

• More freshwater availability

• More frequent tsunamis

• Increased coastal flooding

How does climate change affect mental health?

Which communities are most vulnerable to climate-related disasters?

• People living in urban areas

• Low-income communities

• Coastal tourism businesses

• Wealthy landowners

How can wetlands help reduce the impact of floods?

• They store carbon emissions

• They absorb excess water

• They serve as breeding grounds for mosquitoes

• They act as recreational parks
