WATER CYCLE Hydrologic cycle or H2O cycle

WATER CYCLE:

The water cycle, also known as the hydrologic cycle or H2O cycle. Water can change states among liquid, vapor, and ice at various places in the water cycle. WATER CYCLE

Different Processes :

Different Processes Precipitation Condensed water vapor that falls to Earth's surface. Most precipitation occurs as rain, but also includes snow, hail, fog drip, graupel and sleet. About 505 000 km3 (121 000 cubic miles) of water falls as precipitation each year, 398,000 km3 (95,000 cubic miles) of it over the oceans.

Different Processes :

Different Processes Canopy Interception Precipitation that is intercepted by plant foliage and eventually evaporates back into the atmosphere instead of falling.

Different Processes :

Different Processes Snowmelt The runoff produced by melting snow.

Different Processes:

Different Processes Runoff The variety of ways by which water moves across the land. This includes both surface runoff and channel runoff. As it flows, the water may seep into the ground, evaporate into the air, become stored in lakes or reservoirs, or be extracted for agricultural or other human uses.

Different Processes :

Different Processes Infiltration Infiltration is the process by which water on the ground surface enters the soil. Once infiltrated, the water becomes soil moisture or groundwater.

Different Processes :

Different Processes Subsurface Flow The flow of water underground, in the vadose zone and aquifers. Groundwater can return to the surface (for example, as a spring or is pumped) or eventually seep into the oceans. The water returns to the land surface at a lower altitude than in those infiltrated under the force of gravity-induced pressure or gravity. Groundwater tends to move slowly, and is replenished slowly, so they can remain in aquifers for thousands of years.

Different Processes :

Different Processes Evaporation The transformation of water from liquid to gas phases as it moves from the ground or bodies of water into the overlying atmosphere. The source of energy for evaporation is primarily solar radiation. Evaporation often implicitly includes transpiration from plants, though together they are specifically referred to as evapotranspiration .

Different Processes :

Different Processes Sublimation The state change directly from solid water (snow or ice) to water vapor.

Different Processes :

Different Processes Advection The movement of water — in solid, liquid, or vapor states — through the atmosphere. Without advection, water that evaporated over the oceans could not precipitate over land.

Different Processes :

Different Processes Condensation The transformation of water vapor to liquid water droplets in the air, creating clouds and fog.

Different Processes :

Different Processes Transpiration The release of water vapor from plants and soil into the air. Water vapor is a gas that cannot be seen.

EARTH DAY:

EARTH DAY Save the Earth

EARTH DAY:

Earth Day is the largest, most widely celebrated international environmental event. Earth Day helps celebrate Earth’s unique place in the universe. It is the only planet in our solar system teeming with incredible biodiversity and protecting this biodiversity is what Earth Day is all about. People all over the world celebrate and efforts to protect plants and animals and to clean up the world we live in. EARTH DAY

Slide 3:

Earth Day was founded by United States Senator Gaylord Nelson as an environmental teach-in first held on April 22, 1970. While this first Earth Day was focused on the United States, an organization launched by Denis Hayes, who was the original national coordinator in 1970, took it international in 1990 and organized events in 141 nations. Earth Day is now coordinated globally by the Earth Day Network, and is celebrated in more than 175 countries every year. EARTH DAY

Slide 4:

Why We Celebrate Earth Day? Earth Day reminds us we all share the same planet. Sharing Earth means taking responsibility for what we use and how we use it. It is a day to think of the environmental challenges we face and how to solve them. The Protection of Earth is every person’s and every country’s responsibility.

Rethink, Reduce, Reuse, Recycle:

Rethink, Reduce, Reuse, Recycle Understanding how long something takes to decompose in a garbage dump or landfill can help motivate all of us to reuse and recycle everything we can.

Problems The Environment Faces:

Problems The Environment Faces Air ,water and soil pollution Energy depletion Overflowing landfills Rain forest destruction Vanishing species

What we can do to save our earth?:

What we can do to save our earth? The Running Faucet - Do you leave the water running while you brush your teeth for 2 minutes.. ??? Then nearly ten gallons of water just slid down the drain, turn off the tap until it's time to rinse. Use the same principle when washing dishes and your cars. Avoid using plastic bags as they are non-biodegradable and hurt the environment. Plant lots of lots of trees. Conserve Energy and Switch to Renewable Energy Use Less Water and Keep It Clean Turn Off The Lights. Unplug Appliances When not in use. Separate Your Garbage.

Famous Quotes on Earth Day:

Famous Quotes on Earth Day "Never doubt that a small group of thoughtfully committed citizens can change the world. Indeed, it's the only thing that ever has." -Margaret Mead "There is enough for all. The earth is a generous mother; she will provide in plentiful abundance food for all her children if they will but cultivate her soil in justice and in peace." -Bourke Coekran "What is the use of a house if you haven't got a tolerable planet to put it on?" Henry David Thoreau "The materials of wealth are in the earth, in the seas, and in their natural and unaided productions." -Daniel Webster "... do something. Pay your rent for the privilege of living on this beautiful, blue-green, living Earth." -Dave Foreman "We do not inherit the earth from our ancestors, we borrow it from our children." Native American Proverb

Human BODY

Slide 2:

Two little eyes to look around Two little ears to hear each sound In the middle of my face is my little nose To breathe the air and smell the rose Two little feet that hop and run, One little mouth that talks of fun. two strong arms go up and down, one strong neck that turn around. To taste my food I have a tongue To breathe in and out I have my lungs. My brain tells why 2 +3 make 5 And my heart works hard to keep me alive .

Our body is simply amazing. Each organ in our body has a special function to perform. We can not see all our body parts . Those parts we can see called external organs :

Our body is simply amazing. Each organ in our body has a special function to perform. We can not see all our body parts . Those parts we can see called external organs External organs like shoulder arm wrist ankle hair forehead ear knees

Internal organs -these are the organs which we can not see . Our body is made up of many internal organs. Each part has a job to do.:

Internal organs -these are the organs which we can not see . Our body is made up of many internal organs. Each part has a job to do. Some of the important Internal organs are:- Brain – help us to think. It tells other parts of the body what to do. Lungs – help us to breathe. They supply oxygen to the body. Stomach – stores the food and helps in digestion, Heart – pumps blood to the whole body.

Slide 5:

Some more Internal organs and tissues Nerves – helps us to feel and react. if you touch something hot , you pull back immediately. Bones – give shape to our body, protect soft organs in the body and help us to move easily. Muscles – help us to move and do work. Blood – comes out when there is a cut or injury. Blood transports oxygen and food to all parts of the body. it supports and protects the organs.

Did you know :

Did you know The left lung is smaller than the right lung to make room for the heart. If you could spread the lungs out flat side by side , it would cover an area as big as a tennis court! Some bony facts 1. our body has 206 bones. 2. some parts in our body that do not have bones includes the lower part of the ear (ear lobes) the tongue. the eyelids.

Human Sense Organs – The Five Senses :

Human Sense Organs – The Five Senses Skin – we feel with our skin. we can feel hot and cold, smooth and rough , soft and hard , wet and dry things. The skin on our fingers, hands , legs or other parts of our body help us to feel. Eyes – we can see with our eyes . we can see near and far, shapes and colours , light and dark. our eyelids open and shut. the eyelashes help to keep dust out of our eyes. Ears – we hear with our ears. We can hear loud and soft sounds, pleasant sounds. if a sound is too loud , it can hurt our ears. Nose – we smell with our nose. we can smell aromas , fumes and things which do not smell good. we also breathe with our nose. Tongue – we taste with our tongue. we can taste sweet, salty, sour and bitter things. our tongue also helps us to talk and make sounds.
