What is a natural resource?

Any material or energy source found in nature that humans use to survive or improve their lives (e.g., water, air, minerals, sunlight).

100

What is transformation?

The process of changing energy from one form to another. For example, a toaster transforms electrical energy into thermal energy.

100

What is conservation?

The wise use and protection of natural resources to prevent them from being wasted or depleted. This includes recycling, reducing consumption, and reusing materials.

200

What is a renewable resource?

A resource that can be replaced at the same rate at which it is consumed. Examples include solar energy, wind, and water.

200

What is the law of conservation of energy?

A fundamental law of science stating that energy cannot be created or destroyed; it can only be transformed from one form to another or transferred from one object to another.

200

What is stewardship?

The responsible planning and management of resources. It is the idea that humans have a duty to care for the environment for the benefit of future generations.

300

What is a nonrenewable Resource?

A resource that forms at a rate much slower than the rate at which it is consumed. Once used up, it takes millions of years to replace (e.g., coal, oil, natural gas).

300

What is mechanical energy?

The sum of an object's kinetic energy (energy of motion) and potential energy (stored energy). It is the energy associated with the motion and position of everyday objects.

400

What are fossil fuels?

A nonrenewable energy resource formed from the buried remains of plants and animals that lived millions of years ago.

500

What is green energy?

Energy generated from natural resources that are renewable and have a lower impact on the environment compared to fossil fuels (e.g., geothermal, wind, or solar power).
