WATER CYCLE

WHAT IS WATER CYCLE?The continuous process by which water is distributed throughout the Earth and its atmosphere. Energy from the sun causes water to evaporate from oceans and other bodies of water and from soil surfaces. Plants and animals also add water vapor to the air by transpiration. As it rises into the atmosphere, the water vapor condenses to form clouds. Rain and other forms of precipitation return water to the Earth, where it flows into bodies of water and into the ground, beginning the cycle over again. Also called hydrologic cycle.

EVAPORATION: THE WATER CYCLE

Evaporation is the process by which water changes from a liquid to a gas or vapor.

CONDENSATION: THE WATER CYCLE

Condensation is the process by which water vapor in the air is changed into liquid water.

:

PRECIPITATION: THE WATER CYCLE

Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail.

:

COLLECTION: THE WATER CYCLEWhen water falls back to earth as precipitation, it may fall back in the oceans, lakes or rivers or it may end up on land. 

WHERE IS IT HAPPENING?The water cycle describes the existence and movement of water on, in, and above the earth. We experience primary components of the water cycle everyday we are just unaware of it.

For example, when you get out of a swimming pool on a hot day and realized a few minute later that you are no longer wet; you are experiencing evaporation first hand.

Or when you see water bead up on the side of a cold drink on a hot day your seeing condensation in action.

And when your walking in the rain on a cloudy day you are experiencing precipitation.

Collection- on the other hand is a little more rare in our society since we have set up our cities in such a way that redirects water to collect in other places such as rivers lakes and at the beach.

HOW DOES THE WATER CYCLE AFFECT LIFE ON EARTH?

Water cycle keeps the planet alive by:

Keeping all plants alive,

All plants keep animals alive by sustaining them with food, and also by giving them oxygen to breathe.

The water cycle also dictates things like wind, temperature, storms, topography (erosion)

SOME PROBLEM WITH THE WATER CYCLE?

Climate change creates extreme weather patterns, like drought

• Many places are already having drought, such as California

• Drought and changes in growing seasons will have a major effect on how and where water is relocated around the world

Humans are altering the water system by:

Damming, ground water extraction, irrigation, urbanization, deforestation

WHAT ARE SOME SOLUTIONS?

• California Governor created a statewide Mandatory water reduction

Goal: To reduce water usage by 25% statewide.

HOW ARE WE CONSERVING?

- Lawns: reduce watering the lawn

- Significant cuts in water use on:

Campus’, Golf courses, Parks, Car washes , etc.

- Companies making it easier for new homes to use portable water

for irrigation (American Tank Company)

-Rebates for water- efficient appliances (Energy Star)

WATER FACTS• Water scarcity affects every continent and affects 4 out of every 10 people

(World Health Organization)

• Demand in the U.S. has tripled in the past 30 years while the population has grown only 50% (Goldman Sachs)

• 20% of clean water is lost due to leaks in our pipe systems (EPA)

• Moving and treating water uses 19% of California’s electricity and 30% of its natural gas (California Energy Commission)

• Water related diseases are the leading cause of child death, killing 4,500 children per day (UNICEF)

• Over 80% of US waterways are contaminated by medications (US Geological Survey)

TOTAL WATER WITHDRAWALS IN 2005

Despite the good intentions behind individual citizens conserving their water allotment; less than 1% of our totally water expenditures. The biggest consumers of our fresh water as seen in these figures are by far Thermoelectric, Irrigation, and the Public Supply

TOTAL WATER USE, BY CATEGORY OF USE, 2005

Grain-fed beef production takes 100,000 liters of water for every kilogram of food. Raising broiler chickens takes 3,500 liters of water to make a kilogram of meat. In comparison, soybean production uses 2,000 liters for kilogram of food produced; rice, 1,912; wheat, 900; and potatoes, 500 liters. 

TOTAL WATER WITHDRAWALS, BY STATE, 2005

CONSERVATION TIPS1. Washing Laundry and Dishwashers as full loads

2. Flushing medication into the toilet not only contaminates our water supply but it also uses three times as much water to flush and sanitize the water were pills are present because the are so dense in mass and in chemical composition

3. Plant tree’s and other plants that are local to the area and require less water or could survive by the local minimum rainfall.

4. Take care of our Forest; when forest are cut down, less moisture goes into the atmosphere and average rainfall declines. This process leads to drought and also strips the soil of it’s nutrients and sends it down stream.

5. Avoid eating food that require large amounts of water to grow such as almonds, dairy, and beef.

6. Research ways to make Thermoelectric plants less dependent on our fresh water resources. This is particularly important because the biggest bulk of our freshwater goes to Thermoelectric plants (40%)

SUMMARY

The water cycle describes the movement of water throughout Earth's surface, atmosphere, and underground. Water is constantly moving from one place to another through the processes of evaporation, condensation, precipitation, and collection. Water in the water cycle can exist as a solid, liquid, or gas. The water cycle is very important to life on Earth
