How do winds distribute thermal energy around the Earth?
When warm air rises from the surface as it gets cooler and more dense causing winds. Winds distributes heat energy from the sun that is closest to the equator which heats up the atmosphere unevenly as it spreads heat around the Earth.

What happens in the carbon cycle?
The carbon cycle starts when carbon is created or produced by human activities which then the carbon goes up in the air and in the atmosphere. After that the plants absorb the carbon while on the process of photosynthesis and then the carbon goes into the plant roots and get stored in the ground. After millions of years the carbon will turn to coal, oil and natural gas and then is used by humans.
