Natural Resources and Their Impact

The video discusses natural resources, distinguishing between renewable and non-renewable types. Renewable resources like sunlight, wind, and water are replenished naturally, while non-renewable resources such as fossil fuels are finite. The extraction and use of fossil fuels have significant environmental impacts, including habitat loss, pollution, and climate change. The burning of fossil fuels releases harmful emissions, contributing to global warming and altering ecosystems.

What is a natural resource?

• A part of the earth that people use

• A type of non-renewable energy

• A man-made object used by people

• A type of renewable energy

Which of the following is NOT a renewable resource?

• Coal

• Water

• Sunlight

• Wind

What does it mean for a resource to be renewable?

• It is always available in unlimited quantities

• It is a type of fossil fuel

• It can be replaced or replenished by nature

• It cannot be used by future generations

How are fossil fuels like coal, oil, and gas formed?

• By the accumulation of minerals in water

• From organic matter subjected to heat and pressure over millions of years

• By the erosion of rocks

• Through the rapid cooling of magma

What is a major impact of coal mining on the environment?

• Increased water levels

• Habitat loss

• Reduction in air pollution

• Formation of new ecosystems

What is one way that natural gas and petroleum extraction can harm the environment?

• By causing earthquakes

• By polluting land and water with chemicals

• By increasing the earth's magnetic field

• By reducing the amount of sunlight

What is a consequence of burning fossil fuels?

• Air pollution

• Decreased greenhouse gas emissions

• Increased biodiversity

• Lower global temperatures

What do greenhouse gases do in the atmosphere?

• Reduce the amount of oxygen

• Absorb water vapor

• Trap solar radiation and increase the earth's temperature

• Reflect solar radiation back into space

What is one effect of human-induced climate change?

• Increased formation of fossil fuels

• Changes to many of earth's habitats

• Stabilization of polar ice caps

• Decreased ocean water levels

What evidence have scientists found regarding the burning of fossil fuels?

• It has no effect on the environment

• It causes the earth to warm at a much faster rate

• It causes the earth to cool down

• It has no impact on the earth's temperature
