Carbon is a very complex molecule and a has a unique formula that allows carbon to form tetravalance and have many carbon bonds. Carbon has so many different uses and has many isotopes. It is mostly concentrated in living matter but also is found in the earth. Carbon is cycled through the enviroment by the processes of burning, respiration, and decay. Carbon has recently been taking the blame for the greenhouse effect and for global warming. Carbon dioxide is a green house gas and is one of the gases that increase the temperature of the planet. The burning of fossil fuels is also accountable though. Burning fossil fuels releases excess carbon into the enviroment. The carbon cycle is one of the main ones of all the systems, besides the oxygen cycle. Carbon has recently been taking the blame for the greenhouse effect and for global warming.

The carbon cycle is one of the main ones of all the systems, besides the oxygen cycle. The nitrogen cycle is very important also. It is an important nutrient cycle and produces amino acids, proteins, and nucleic acids. Nitrogen comes mostly from the atmosphere but in cycled through plants. The oxygen cycle is the cycle of oxygen through the air, living things, and the earths crust. All the cycles interact to make this world a livable place. The cycles are really complex and all are intertwined.

Water is an essential element that affects all living things. All plants and animals need water to survive. Luckily it is something that cycles and is a renewable resource. There are many different aspects of the water cycle including evaporation, transpiration, condensation, precipitation, infiltration, surface runoff, groundwater, and absorption. They all work together to get the water cycle working. Evaporation is 80% of the water for precipitation. It is the process where water is transferred from its liquid to its vapor form. Evaporation is dependent on some abiotic factors. It is affected by wind speed, humidity, and temperature. Transpiration is sort of similar to evaporation it is the loss of water from plants. Condensation is the reverse of evaporation and is the change of mass from the gaseous state in the liquid phase. Precipitation is any product of atmospheric vapor that falls to the Earth in the forms of rain, snow, hail, or sleet. Infiltration is when water on the ground surface enters the soil. It is responsible for groundwater and water sheds, it is a very helpful process. Surface runoff is water that flows over the earths surface. Ground water is water located beneath the earths surface. Absorption is the absorbing of water particles. In a water shed the water flows all around, it can be a stream or the ocean. It is a thing that holds water. There are many types of rivers and streams. flooding helps some places and too much can become very harmful. Erosion is a process that breaks downs solids and water is the corrosive thing that plays a big part in breaking them down. Deposition is when land is moved from one side of the river to another.

I read multiwavelength astromy. It taught me about heat & wavelengths. I only got 1 out of 3 on the test right tho... The try me activity was a bar graph measuring different types of energy.
