Cycles of the Earth System

 Our planet is constantly changing. Natural cycles balance and regulate Earth and its atmosphere. Human activities can cause changes to these natural cycles.

Life on Earth is well adapted to our planet’s cycles. In our solar system, Earth is the only planet with air to breathe, liquid water to drink, and temperatures that are just right for life as we know it. Because our existence depends on our planet and its climate, we need to understand how what we do affects the Earth.

Scientists try to figure out how our planet works by studying Earth’s cycles. Changes to Earth’s cycles can cause changes in the climates of our planet.
