1. What term describes the long-term patterns of weather in a particular area?

   Meteorology Atmosphere Climate Weather

   ✓ Climate

   Climate refers to the average weather conditions over a long period, typically 30 years or more, in a specific region.

2. Which of the following is a major greenhouse gas that traps heat in the Earth's atmosphere?

   Oxygen Nitrogen Carbon Dioxide Hydrogen

   ✓ Carbon Dioxide

   Carbon Dioxide (CO2) is a primary greenhouse gas. When released into the atmosphere, it absorbs and re-emits infrared radiation, contributing to warming.

3. What is the process called when ice turns directly into water vapor without melting first?

   Condensation Evaporation Sublimation Precipitation

   ✓ Sublimation

   Sublimation is the transition of a substance directly from the solid to the gas state, bypassing the liquid phase. This can happen with ice and snow in cold, dry conditions.

4. What does the term 'global warming' specifically refer to?

   A sudden increase in ocean tides The gradual increase in Earth's average temperature A decrease in the Earth's magnetic field More frequent earthquakes

   ✓ The gradual increase in Earth's average temperature

   Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.

5. Which word describes the variety of life in the world or in a particular habitat or ecosystem?

   Ecosystem Habitat Biodiversity Biome

   ✓ Biodiversity

   Biodiversity refers to the variety of all life forms on Earth, including the diversity within species, between species, and of ecosystems. It is crucial for a healthy planet.

6. What term is used to describe the melting of ice sheets and glaciers, contributing to rising sea levels?

   Desertification Deforestation Glacial retreat Ocean acidification

   ✓ Glacial retreat

   Glacial retreat is the shrinking of glaciers and ice sheets. As they melt, the water flows into the oceans, causing sea levels to rise.

7. What is the term for a long period of abnormally low rainfall, leading to a shortage of water?

   Flood Drought Tornado Hurricane

   ✓ Drought

   A drought is a prolonged period where a region experiences a shortage of water, often due to insufficient rainfall.

8. Which of the following is a renewable energy source that is often used to generate electricity without producing greenhouse gas emissions?

   Coal Natural Gas Solar Power Oil

   ✓ Solar Power

   Solar power harnesses energy from the sun and is a renewable resource that does not produce greenhouse gases during electricity generation.

9. What does the term 'carbon footprint' measure?

   The amount of plastic waste a person produces The total amount of greenhouse gases generated by our actions The distance traveled by a car The number of trees in a forest

   ✓ The total amount of greenhouse gases generated by our actions

   A carbon footprint is the total amount of greenhouse gases, including carbon dioxide and methane, that are generated by our actions, such as burning fossil fuels and deforestation.

10. What is 'ocean acidification' primarily caused by?

    Increased plastic pollution in the oceans The absorption of excess carbon dioxide from the atmosphere by seawater Overfishing of marine life Rising ocean temperatures

    ✓ The absorption of excess carbon dioxide from the atmosphere by seawater

    Ocean acidification occurs when the ocean absorbs excess carbon dioxide (CO2) from the atmosphere. This CO2 reacts with seawater to form carbonic acid, which lowers the ocean's pH.
