Earth is the only planet in our solar system that provides a suitable environment for life as we know it. Sustaining these conditions requires a constant recycling of materials between the living and nonliving components of eco-systems.
Select one of material cycles we studied (water, nitrogen, carbon, sulphur and phosphorus) and identify elements of your lifestyle that impact the cycle.
a. What are the most considerable impacts you make?
b. How might it change your life if you were to reduce your impacts? What would you need to give up?
c. How difficult is to balance personal choices with environmental considerations?
Your answer should be between 700–900 words long and should include introduction and conclusion sections.
Water is a necessity for the existence of human beings. Approximately 71 % of the earth is water and it exists in many different forms. From water vapor in the atmosphere, to rivers and lakes on the earth’s surface to glaciers and icecaps to aquifers in the ground. Water is constantly moving from one place to the other and from one state to the other and this process is known as the water cycle. As water evaporates, vapors rise and condense into clouds. The clouds move over the land, and precipitation falls in the form of rain, ice or snow. The water fills streams and rivers, and eventually flows back into the oceans where evaporation starts the process anew. Water 's state (solid, liquid or gas) is determined mostly by temperature. Although water continuously changes states from solid to liquid to gas, the amount of water on Earth remains constant. There is as much water now as there was hundreds of millions of years ago (Project, 1995).

...s emission from cars, etc. has an effect on the overall increase of the Earth’s temperature and the water cycle. Sulfur and CO2 mixes with water vapor in the atmosphere, therefore when it falls as rain the chemicals in the water also falls as acid rain. This sometimes kills trees, which means there will be less trees to slow down surface run off so it can sink into the ground and become underground water. Also, raising the Earth’s temperature may mean that there is an increase of evaporation, melting of ice or other processes of the water cycle that adversely affect the climate on Earth. If we stop littering and choose to put our trash away properly we could reduce the effects of water pollution which affect the water cycle. If we quit smoking and excessive and unnecessary driving, we will be able to reduce the negative impacts of global warming on the water cycle.
In addition to lowering greenhouse gas levels and using cleaner energy sources, there are things we can do as people to stop climate change. We could reduce our use of electricity at our homes by turning off the lights when we leave the room, turning down/up the heating/ac when it is unnecessary, and using less water. Also, we could install solar panels in our homes and donate money to environmental protection agencies. Hopefully, the people of our world will soon realize climate change is a pressing issue that must be solved as soon as
The following Essay must be a minimum of 5 paragraphs of 10-12 sentences each (a sentence is 10 words or more) .
In response to the question set, I will go into detail of the study, consisting of the background, main hypotheses, as well the aims, procedure and results gathered from the study; explaining the four research methods chosen to investigate, furthering into the three methods actually tested.
Water has three stages—liquid, gas and solid. Water on Earth can be liquid as rain, streams, or oceans. It can be a solid like hail, ice or snow. It can be a gas like vapor, steam or clouds. As described by the Department of Atmospheric Sciences (2010), the hydrologic cycle is the process of water changing from liquid to gas to solid. The energy of the sun drives the changes to water. When water is heated up, it evaporates, turning into a gas to form steam or vapor. The water vapor rises with warm air that when meets cooler air, condenses to form clouds. These clouds and water vapor can be transported around the world. Precipitation is when water falls to Earth, in warmer temperatures as liquid and in temperatures, as a solid. On Earth, precipitation can evaporate again or infiltrate the Earth to become groundwater. As ground water it can collect in oceans, rivers or on snowy mountaintops and glaciers. It can also be released back into the atmosphere via transpiration, when water evaporates off soil, trees. When water evaporates, the cycle starts again.
There are numerous stages that take place simultaneously in the hydrologic cycle and this includes evaporation. This is when the water alters from a liquid state into a gas. The damp air from the water rises into the atmosphere and when it cools, the vapor condenses and shapes into clouds. But those billows are not the only form the vapors make; it can also materialize as dew, fog and mist, which blanket the Earth, characteristically on a rainy or humid day. Evaporation takes place when water changes from a liquid state into a gaseous state, and ascents out of the pores of the earth and into the atmosphere as a vapor (“How”). While evaporation is taking place, condensation is also occurring. When the temperature in the air plunges, the clouds become heavy and as a result they relieve themselves of the extra weight, which is called precipitation. This produces rain, hail, snow and sleet, conditioned upon the temperate. As the precipitation falls, it enters the surface of the ground and percolates into the soil, which is called infiltration. The more porous the land is, the more the infiltration can take place. However, the ground cannot hold all of that water and floods. The excess rainfall, which is also called runoff that has not been absorbed makes its way into bodies of water, such as small ponds, rivers, lakes and parts of the ocean (“Summary”).

IV. After a brief background discussion, I will talk about recycling how to’s for those of you who proclaimed good intentions but no know-how. Then I will discuss the benefits of recycling and the negative impact of not recycling has wreaked on our planet.
The hydrologic cycle, also known as the water cycle, describes how all the water in the hydrosphere continually moves between oceans, lakes, rivers, land and atmosphere. During the course of the water cycle, water changes state from liquid to gas and back to liquid. The energy that drives the hydrologic cycle comes from the sun. The steps in the water cycle are evaporation, condensation, precipitation and runoff. Transpiration is an additional element in the water
Recycling. What does this word mean to you? Do you recycle? Do you support or oppose the act of it? What is written in the following paragraphs may or may not help you make this one special planet in our solar system we call Earth; the only planet scientists know supports life. Recycling benefits many aspects of life. Recycling benefits the aesthetics of our daily environment, it makes our family and friends safer from sickness, it boosts our economy, and it allows us to make more use of the limited natural nonrenewable resources we have on our earth. Recycling will benefit life by reducing our environmental impact, preventing injury, boosting the economy, and extending the use we can make can make out of our resources.
In conclusion, global climate change is a very long discussion with many ways to improve the environment, but a long journey to finding a solution. Although we can 't do away with our main sources like power plants, cars, and factories we must continue to find solutions to making our environment safer and suitable to live in. Hopefully in the near future we will have a better understanding of how to address our global climate changes, but for now, we can focus our ideas on preventative ways to not harm ourselves and our

Water covers about seventy one percent of Earth’s surface. Earth is the only planet to have stable bodies of liquid water on its surface which is crucial for all known life forms. Water is a substance which acts as a solvent in which organic compounds can mix, and it is the substance which is thought to be necessary to facilitate the formation of life. There are many forms of water which include ice, liquid, and gas. Because water can exist as a gas, it can be stored in the atmosphere and be delivered as precipitate. Water also helps regulate the climat...
