The earth has a limited amount of water.That water keeps going around and around and around in what we call the "Water cycle".It is the only way that Earth can be continually supplied with fresh water.The sun is the most important part of renewing our water supply.It can be solid (ice)‚a liquid (water)‚ or gas (water vapor). Water on earth is always changing. How do these changes happen? It is made up of a few main parts:evaporation (and transpiration)‚condensation and precipitation. Evaporation

The economic cycle is a fundamental economic understanding of the phases that an economy may experience during certain climates. This can be understood by the basic economic cycle diagram‚ which shows the different periods combined with a line representing trend growth. Governments ideally wish for uniform growth‚ close to or on the trend line‚ this is where the economy is continually expanding and growing at a rate which the government perceives to be sustainable. For example‚ the UK aim for 2.5%

A nutrient cycle (or ecological recycling) is the movement and exchange of organic and inorganic matter back into the production of living matter. The process is regulated by food web pathways that decompose matter into mineral nutrients. Nutrient cycles occur within ecosystems. Ecosystems are interconnected systems where matter and energy flows and is exchanged as organisms feed‚ digest‚ and migrate about. Minerals and nutrients accumulate in varied densities and uneven configurations across the

The stage cycle Stage one is the beginning of the sleep cycle‚ and is a relatively light stage of sleep. Stage one can be considered a transition period between wakefulness and sleep. In Stage one‚ the brain produces high amplitude theta waves‚ which are very slow brain waves. This period of sleep lasts only a brief time (around 5-10 minutes). If you awaken someone during this stage‚ they might report that they weren’t really asleep. Stage two is the second stage of sleep and lasts for approximately

The Calvin Cycle By: MJ Pineda The Calvin Cycle is basically a part of photosynthesis where plants take in carbon dioxide and uses ATP and NADPH to make sugars from the CO2 and water for the plant to use or for animals to eat. It does not require light‚ and is interestingly called the "dark cycle" 1. The first step of this cycle consists of A carbon atom from carbon dioxide molecule will enter the cycle and joins with a five carbon molecule that is present. 2. The six carbon molecule that
