Cycles of Matter

We present new evidence of a 6-year cycle in the climate system. A 6-year cycle is evidenced in the global water cycle with satellite gravimetry.

Earth's surface systems involve many cycles, such as carbon, nitrogen, and oxygen, which support life. Cycles that exchange materials among living and nonliving ... The Rock Cycle · The Water Cycle · The Nutrient Cycle

Rain and surface runoff are major ways in which minerals, including carbon, nitrogen, phosphorus, and sulfur, are cycled from land to water. The environmental ...

Exhibit Global cycles of life-giving elements Elements that sustain life stay in the Earth's reservoirs for different lengths of time.

The theory argues that there are many feedbacks that evolved though time that regulate the abiotic processes, maintaining our planet's livability.

Milankovitch cycles describe the collective effects of changes in the Earth's movements on its climate over thousands of years.

Carbon flows between the atmosphere, land, and ocean in a cycle that encompasses nearly all life and sets the thermostat for Earth's climate ...

The water cycle is the endless process that connects all of that water. It joins Earth's oceans, land, and atmosphere.

The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes.

The water cycle, also known as the hydrologic cycle, describes where water is stored on Earth and how it moves. Water is stored in the atmosphere, ...
