All non-renewable resources theoretically can be exhausted or depleted.
True
False
True
False
True. Non-renewable resources, such as fossil fuels like oil, coal, and natural gas, are finite resources with a limited supply in the earth's crust. As they are used and extracted, they can become depleted, leading to increased costs and environmental impacts. Renewable resources, such as solar or wind energy, are not finite and can continuously be replenished, making them more sustainable.
Recycling aluminum cans will help to reduce the amount of waste in a landfill.
True
False
True
False
True. Recycling aluminum cans helps to reduce the amount of waste going to landfills. Rather than being thrown away, the aluminum from the cans can be melted down and used to create new products, reducing the need for virgin materials and decreasing the amount of waste going to landfills. Recycling also conserves energy since producing aluminum from recycled materials requires less energy than producing it from virgin materials.
Todd's teacher told him that the gas used to power cars is a natural resource and would run out in the future, and he could help to conserve this natural resource by ________________.
a
using a gas-powered car
b
using an electric-powered car
a
using a gas-powered car
b
using an electric-powered car
b. Using an electric-powered car. Gasoline, which is used to power most cars, is a non-renewable resource that is expected to become depleted in the future. Using an electric-powered car is one way to reduce dependence on gasoline and help conserve this natural resource. Electric cars run on batteries that can be charged with renewable energy sources such as solar or wind power, making them more sustainable and environmentally friendly than gas-powered cars.
The best question to ask in order to immediately determine whether or not an energy resource is renewable is how long until it runs out.
True
False
True
False
False. Asking how long until an energy resource runs out is more relevant to determining whether a resource is non-renewable rather than renewable. The best question to ask in order to immediately determine whether or not an energy resource is renewable is: Does this resource replenish itself naturally and quickly enough to be considered sustainable, or is it a finite and depletable resource? Renewable resources can be replenished naturally and sustainably over time, while non-renewable resources are finite and eventually depleted.
Rare earth metals are rarely found in large quantities on Earth. Instead, they are spread very thinly throughout Earth's crust, making them very difficult to get. Once the resources such as oil are all used, they are gone forever.
True
False
True
False
False. While it is true that rare earth metals are not found in large quantities on Earth and can be difficult to extract, it is not true that once a resource like oil is used, it is gone forever. Non-renewable resources like oil are finite and have a limited supply, but they can still be conserved and recycled. Additionally, as technology advances, other potential sources of energy and resources may become economically viable to extract and use. However, it is still important to transition towards more sustainable energy and resource use in order to reduce our dependence on non-renewable resources and minimize environmental impacts.

True
False
True
False
True. Conservation is the best way to reduce the need for additional energy consumption. By conserving energy, we can reduce the amount of energy needed to power our daily activities, such as lighting, heating and cooling, and transportation. This can help to reduce our dependence on fossil fuels, decrease greenhouse gas emissions, and conserve our natural resources. Conservation can take many forms, such as using energy-efficient appliances, turning off lights when leaving a room, reducing unnecessary travel, and insulating homes properly.
As time passes, will global oil reserves continue to increase or decrease as we use them?
a
Decrease
b
Increase
a
Decrease
b
Increase
a. Decrease. As we use global oil reserves, they will gradually decrease over time. This is because oil is a non-renewable resource that takes millions of years to form, and the rate of extraction and consumption is typically faster than the rate of formation. As oil reserves become depleted, it becomes more difficult and expensive to find and extract new reserves, leading to an eventual decline in production. This underscores the importance of transitioning to renewable energy sources and reducing our dependence on fossil fuels.
