Environmental Studies Quiz

Carbon dioxide is a greenhouse gas that contributes significantly to global warming by trapping heat in the Earth's atmosphere.

Sunlight is the primary source of energy for photosynthesis, which forms the basis of most ecosystems.

Coal is a fossil fuel formed from decayed plants and animals over millions of years and is considered non-renewable because its formation takes much longer than its consumption rate.

Plankton are microscopic organisms found in bodies of water; they are not components of soil, which typically consists of minerals, organic matter, water, and air.

Condensation is the process by which water vapor in the atmosphere cools and forms liquid droplets, such as clouds or dew.

Solar power is derived from sunlight and is considered a renewable energy source because it is naturally replenished.

Transpiration is the process by which water is absorbed by plant roots, moves through the plants, and then evaporates into the atmosphere through pores in leaves.

Global warming refers to the long-term increase in Earth's average surface temperature due to human activities such as burning fossil fuels and deforestation.

Agricultural runoff, which includes pesticides, fertilizers, and animal waste, is the largest source of water pollution globally, affecting rivers, lakes, and oceans.

Habitat destruction, such as deforestation, urbanization, and pollution, leads to the loss of habitats for various species, resulting in a decline in biodiversity.

Nitrogen is not a greenhouse gas; it constitutes about 78% of the Earth's atmosphere and does not significantly contribute to the greenhouse effect.

Chlorofluorocarbons (CFCs) are synthetic compounds used in refrigeration, air conditioning, and aerosol propellants, which are responsible for ozone depletion in the Earth's atmosphere.

Burning fossil fuels releases carbon dioxide into the atmosphere, which is absorbed by the oceans, leading to ocean acidification.
