Transcript of Study Notes For Science

IMPORTANT SCIENCE NOTES Evaporation Transpiration Condensation Precipitation Surface Runoff/Infliteration Is the process of which the sun heats up the water
into the form of vapor or steam (Evaporation) Is the process when Water forms as a cloud (Condensation) Is any form of water that falls to the earths surface (Precipitation) Is the process by which water on the ground surface enters the soil (infilteration) Overland flow of exess water (Surface Runoff) The most Frest Water on earth is in ice caps or glaciers and this is not commonly used because it's unaccessable. As the climate warms more glaciers are melting causing extreme flooding in some areas Most of Earths water is in the oceans which is to salty to use the little bit of water in the atmosphere is important because it is the the transportation to move water from place to place. It is the rain and snow that transports water from the ocean back in-land. It also transforms salt water into fresh water. We have a benefit to living here by the great lakes because there is lots of fresh water available to us and we get percipitation from the water evaportating. We must be cautious to not comsume water that is polluted or contaminated. Water is a limited source, we must conserve it. A Watershed~ is an area of land where all the water eventually drains into one main water body, such as a stream, river, wetland, lake, or ocean Weather changes daily and with seasons
Weather changes over years and centuries CHANGING CLIMATES: WATER AND CLIMATE Ocean surface currents cary heat from place to place
Warm currents start near the equator
Warm currents affect the climate and sea life where it circulates HOT AND COLD CURRENTS Water has a high heat capacity meaning it take time to heat or cool
Warm currents flow from the equator, cold currents flow from Anartic
Warm currents affect nearby shoreline weather
Cold currents draw heat from the air THE EFFECTS OF ICE ON WATER SYSTEMS changes in the size of glaciers and ice sheets influence local and global water systems when temperature and percipitations amounts change signifficantly over time, glaciers and ice sheet are affected, increasing or decreasing in size the global climate has undergone natural periods of cooling and warming since Earth formed when earths glaciers and ice sheets begin to disappear, these times are called interglacial periods- in recent decades, glaciers in many parts of the world have been receeding at a steady rate CISOGAGWS Cierra Is SO Going About Global Water Systems = Change In Size Of Glaciers Affect Global Water Systems GWAG George Wants A Goat = Global Weather Affects Galciers:) DGCIP- Dad Got Cups In Pantry = Dissapearing Glaciers Called Interglacial Periods GAG = Glaciers Are Going THE END Evaporation through a plant The Process to Clean Water First the the intake where you find your water source and bring it to you Second is where you add chemicals to the water like Lime and Alum Third comes the processes of Coagulant and Sedimentation Coagulate is to change a liquid into a thickened mass Sediment is the matter that settles to the bottom of a liquid Here the water is starting to Coagulate Here the water is in the process of Sedimentation Next is the filteration and in this coming picture you can see what it looks like Charcoal a thin layer of cotton swab thats ripped apart sand Gravel cloth in the coming picture you'll see water in a storage tank, that's the next step, storing the water is when the sun heats up the water into the form of vapour of steam evaporation through a plant is when the vapour or steam collects as one, for example a cloud as you get farther away from a lake ~the temperature goes up:) ~the number of frost free days per year goes down:( ~the annual precipitation goes up:( as you get closer to a lake ~the temperature goes down:( ~the number of frost free days goes up:) ~the annual precipitation goes down:)
