Examples of this form of energy include the light we receive from the sun and the microwaves we use to pop popcorn.

Since energy can neither be this nor this, it is constantly moving or changing form.

The Sun is primarily made of these two gas molecules.

Weather refers to the moment-to-moment atmospheric conditions, while this refers to the long-term averages that change slowly.

Like many energy resources, wind power involves spinning one of these machines to generate electricity.

Objects in motion have high amounts of this type of energy.

Heat refers to energy being transferred from one substance to another, while this measures the speed at which particles move when they gain heat energy.

Intense pressure in the Sun's core causes this process, combining light elements into heavier ones and releasing lots of energy.

This category of gases allow visible light to shine through but trap heat radiating back up from the Earth's surface.

This renewable energy resource uses heat from within the Earth to produce electricity.

This stored energy is released when an object moves, like a roller coaster at the top of a hill ready to roll down.

The Sun shares its energy with us through this form of heat transfer.

Atmospheric ozone absorbs a lot of this energy wavelength, protecting our skin from damage.

This solid fuel is produced from ancient plants and is mined to produce more electricity than any other fuel source in the US.

These types of dams harness the kinetic energy of rivers to produce power.

A frozen turkey left out to thaw is gaining this form of energy as its molecules start to move faster.

This form of heat transfer occurs when two objects of different temperature make direct contact.

The heat we feel from the Sun is transmitted by this wavelength of radiation.

Gasoline is a refined version of this liquid fossil fuel.

This radioactive element is mined to be the primary fuel source for Nuclear Power Plants.

Chemical energy is stored in these between the atoms of molecules.

Energy moves through our atmosphere by hot air rising and cold air falling, which is known as this process.

The Sun was formed when one of these giant clouds of gas collapsed due to its own gravity.

This fossil fuel burns cleaner than the other two, but leaks can still be very dangerous.

This fuel source is considered "carbon neutral" because growing the materials to make it absorbs carbon dioxide.
