Cycles of matter

If there weren't any Cycles of Matter, or processes of transporting and transforming matter within a system, key elements such as carbon, nitrogen, hydrogen, and oxygen wouldn't be able to change forms but be stuck in one form forever.
Matter Cycle- matter is constantly cycled between living and nonliving parts of the environment. Processes like photosynthesis and nitrogen fixation allow the carbon and nitrogen cycles to regenerate needed substances by recycling earth's atoms.
Rock Cycle- an idealized cycle of processes undergone by rocks in the earth's crust, involving igneous intrusion, uplift, erosion, transportation, deposition as sedimentary rock, metamorphism, remelting, and further igneous intrusion. Nitrogen Cycle- the series of processes by which nitrogen and its compounds are inter-converted in the environment and in living organisms, including nitrogen fixation and decomposition. Nitrogen also travels through the water cycle through reservoirs such as surface water, oceans, and groundwater. Carbon Cycle- is a very important element, as it is a building block of all organic matter, including parts of the human body, such as proteins, fats, DNA and RNA. Carbon can mainly be found in air as carbon dioxide, but as a part of the carbon cycle it may also be dissolved in water or stored in sediments. Water Cycle- The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation. The water falling on land collects in rivers and lakes, soil, and porous layers of rock, and much of it flows back into the oceans, where it will once more evaporate. The cycling of water in and out of the atmosphere is a significant aspect of the weather patterns on Earth. Nitrogen Fixation- a process in which nitrogen (N2) in the atmosphere is converted into ammonium (NH4). Atmospheric nitrogen or molecular nitrogen (N2) is relatively inert, it does not easily react with other chemicals to form new compounds. |

Cycles of Matter
All elements of the periodic chart can be found on earth in many different forms. The elements may differ in physical form and be either solid, liquid or gaseous, or they may differ in their overall form as a result of chemical reactions they have undergone. Elements such as nitrogen can be found on many different locations. Nitrogen is present in water as well as in air and soil and the supplies are always restored. This is because nitrogen, just like many elements, moves across the earth in a matter cycle; the nitrogen cycle. The most important cycles of matter will be described here; those of water, nitrogen, phosphorus, sulfur and carbon.
Cycles of matter describes the process of Earth's elements breaking down over time. Cycles in Earth's many systems include the water cycle, nitrogen cycle, rock cycle, carbon cycle, and the matter cycle. Each different cycle has various steps in transforming into different stages in the cycle. The cycle of matter on earth has changed in the course of the evolution on Earth, and in the recent period, it has been most harmful on the earth’s surface. Only a small part of the matter of the lithosphere,
atmosphere, hydrosphere, and biosphere is involved in intensive exchange. The cycle on earth consists of many varied transformations
and migrations of matter, the basic features of which are recurrent. Individual processes are a succession of changes in matter changing
with temporary states. As soon as a substance emerges from a particular system, it keeps changing until it returns in part to its original state. It never completely returns to its original state, because of the loss of matter in each changing state.

The Greenhouse Effect occurs because gases like carbon dioxide and methane, trap the heat from the sun which warms the atmosphere. The atmosphere warms up because increasing carbon dioxide and methane, means that the concentration of gases already in the atmosphere change. This then increases the amount of heat from the sun that is taken in. The Greenhouse Effect can lead to the ice caps melting, changes in climate, increasing diseases such as cancer, and disrupting ecosystems. Without the Greenhouse gases though, the Earth would be about -20 degrees Celsius or -4 degrees Fahrenheit.
