Transcript of Water System

By: Cindy Chen The water cycle is a cycle in which water moves from the seas and rivers and reaches the sky, then reaches earth back again in the form of percipitation. Evaporation Evaporation is the process in which sun heats up the liquid/water in the ocean and lakes then converting it into a form of vapor or steam. Condensation Condensation is the process by which water changes its state from a vapor or gas to a liquid, forming little water droplets, which then form a cloud. Percipitation Infiltration Infiltration is the process by which water on the ground surface enters the soil. Percipitation is any form if water that falls to the earth's surface. Different types of percipitation include hail, snow, sleet or rain. Percipitation is important bacause it maintains the atmophoric balance. Surface Runoff Overland flow of excess water. Water Cycle Vocabulary Osmosis- process where molecules of water pass through a membrane from a less concentrated solution into a more concentrated one to equalize the concentrations on each side of the membrane.
Desalination- to make salt out of water.
Carbon Nanotubes- tiny tubes about 10,000 times tinner than a human hair -- consist of rolled up sheets of carbon hexagons. Discovered in 1991 by researchers at NEC, thay have the potential for use as minuscule wires or in ultrasmall electronic devices.
Biomimetics- the study and development of synthetic systems that mimic the formation, function, or structure of biologically produced substances and materials and biological mechanisms and processes.
Coagulation- to change from a fluid into a thickened mass; curdle; congeal: Let the pudding stand two hours until to coagulates.
Disinfect- to cleanse so as to destroy or prevent the growth of disease-carrying microorganisms: disfect a wound.
Turbidity- having sediment or foreign particles stirred op or suspended; muddy. Water Distribution Humans must have freshwater to live. But about 97% of the Earth's water if too salty to use. The remaining 2.8% is freshwater, but most of it is in icecaps, glaciers, and ground water and is not easily accessible. Accessible freshwater, therefore, comes from lakes, rivers, and the armosphere. The water cycle balances atmosphere water with liquid water over Earth. The water, however, is distributed unevenly about the world. Earth's Total Freshwater Supply Icecaps & glaciers 2.38%
Ground water 0.397%
Surface water 0.022%
Air & soil 0.001%
Total Freshwater 2.8% Most of the Earth's water is in the ocean which is too salty to use. Rain and snow from the atmosphere that transports the water from the oceans back in-land. It also transforms salt water into fresh water. We have a huge source of fresh water available to us and we get precipitation from the water evaporating off of the lakes. This makes our area also ideal for agriculture. We must be cautions to not consume water that is polluted or contained water is a limited resource that we must conserve to ensure we don't run out. Surface currents in the ocean carry heat from one place to another. Warm currents begin near the equator, where the Sun's heat is most intense. As these warm currents circulate, they affect the climate and sea life of the regions to which they move.
Warm ocean currents affect climate by transferring their heat to the atmosphere. Water has a very high heat capity, which means that it takes a relatively long time to heat up or cool down. Large bodies of water act as heat reservoirs in the winter. remaining warmer than the land nearby. The difference in temperature between the water and land affects the weather systems near the shoreline. These systems produce breezes that alter the processes of evaporation and condensation near the shoreline. Water & Climate Water System
