These are the remains of ancient plants and animals that we burn for energy, like coal, oil, and gas.

What are fossil fuels

100

It takes this many millions of years for carbon to finish one full "slow" trip

Hint: Its in the millions

What is 100 to 200 million years?

100

Plants inhale" this specific gas from the air to make their own food

What is Carbon Dioxide (CO2)?

100

This is the main way carbon moves from a plant into an animal’s body.

What is eating (or the food chain)?

100

This is the element that the whole cycle is named after

what is carbon

200

This type of rock, often made from crushed seashells, stores carbon for millions of years.

What is Limestone

200

This is the largest "sink" or storage spot for carbon on the entire planet.

What is the ocean (or rocks)?

200

During this process, plants use sunlight to turn carbon into sugar.

What is photosynthesis?

200

 A forest fire is a fast way to move carbon from trees back into this part of the Earth.

What is the atmosphere (or the air)?

200

Because carbon traps heat in the atmosphere, it is known as this type of gas

greenhouse

300

Over millions of years, heat and this "heavy" force turn dead organisms into oil and coal.

What is pressure

300

This happens when rain and wind slowly break down rocks, carrying carbon into the sea.

What is weathering (or erosion)?

300

This is what we call it when humans or animals breathe out carbon dioxide.

What is respiration?

300

This "D" word describes how carbon gas from the air moves into the surface of the ocean water.

What is diffusion?

300

This is the chemical symbol for Carbon

What is C?

400

This is the name for the massive "storehouses" where carbon stays trapped for a long time.

What are Carbon reservoirs

400

When tectonic plates move, they push carbon deep into the Earth in this process.

What is subduction

400

These organisms, like mushrooms and bacteria, break down dead things and release carbon back into the soil.

What are decomposers?

400

If a tree lives for 100 years and then rots, its carbon journey is part of this cycle.

What is the Fast Cycle?

400

humans are adding extra carbon to the air by burning this

what is fossil fuels

500

Carbon can be released from deep underground during this explosive geological event.

What is a volcanic eruption

500

This frozen ground in the Arctic acts like a giant "freezer" for carbon until it melts.

What is permafrost?

500

 These tiny, plant-like organisms in the ocean do most of the world's "fast" carbon recycling.

What is phytoplankton?

500

Besides CO2, cows and landfills release this other carbon-based gas into the air.

What is methane?

500

This is the part of the Earth where all living things (and their carbon) exist.

What is the biosphere
