Transcript of The 3 Cycles

The Water Cycle The water cycle is a repeating cycle
of water circulating from water, to the
atmosphere, and to land. The Water Cycle has 4 Main Parts
~ Precipitation
~ Evaporation
~Collection The Sun It's usually the main vocal point
of the water cycle, because it offers
energy that heats the earth's water
surface. Which leads to precipitation,
evaporation, and condensation. It's always changing states between liquid, vapor(gas), and ice (solid). Precipitation Precipitation is the main source in the water cycle to deliver water to earth. It starts with clouds having water vapor and cloud droplets in them. Then tiny water droplets starts to form and condense. Then the drops begin to grow with more water vapor and collide.After all these step and enough collisions the precipitation begins to fall.Precipitation is rain, hail, snow, sleet , and freezing rain. Condensation Condensation is the process which water vapor in the air is changed into liquid water. it's really important to the water cycle because it's responsible for the formation of clouds. Then the clouds can produce precipitation, which is the primary route for water to return to the Earth's surface within the water cycle. http://ga.water.usgs.gov/edu/watercycle.html Other Parts of the Water Cycle The Other Parts of the Water Cycle

Period 8 The Carbon Cycle & The Nitrogen Cycle The Nitrogen Cycle parts are:
~ Animal life/Ammonia
~ Bacteria
~Plants/Algae THE NITROGEN CYCLE THE WATER CYCLE The Carbon Cycle parts are:
~Fossil Fuels
~Humans/Deforestation THE CARBON CYCLE Evaporation is the process by which water changes from a liquid to a gas or vapor.It's the primary route that water moves from the liquid stage and back into the water cycle.Oeans, seas, lakes, and rivers provide nearly 90% of the moisture in the atmosphere evaporation, and plant transpiration is the remaining 10% being contributing. The process of evaporation starts with the sun giving off heat, which make the water turn into the water vapor then evaporation goes into condensation . Evaporation Collection Collection is when precipitation has fallen back into oceans, rivers, land, and lakes. If the precipitation falls on lands it soaks into the ground or become "groundwater" that plants and animals drink from. Groundwater/Infiltration Groundwater is precipitation that has fallen into the ground. Some of it flows along the land surface to streams or lakes, some soaked up by plants, some evaporates and returns to the atmosphere. And some seeps underground, into pores between sand, clay and rock formations called aquifers. Which are used to get clean water by pumps or wells. Fresh Water Storage One part of the water cycle that is very important to all life on Earth is the freshwater existing on the land surface. It can be found in streams of all sizes, all rivers, small creeks, ponds, lakes, reservoirs and canals and man-made lakes and streams. On this diagram, it shows that only 3% of
earth's water is fresh water and most are from
glaciers and groundwater. It also shows that
0.3% is surface water and those are Rivers (2%),
Swamps (11%), and Lakes (87%). Plants/Transpiration The full name of this is called evapotranspiration.
It's a combination of evaporation and transpiration and a invisible process that plants do to release water vapor into the atmosphere. Run Off Run off is just when precipitation has fallen on the ground and starts flowing downhill to the nearest collection of water. The Nitrogen Cycle describes how Nitrogen moves between plants, animals, bacteria, the atmosphere , land and water. Animal Life/Ammonia Animal life is very crucial to this cycle because they produce waste, which is called ammonia. The effect ammonia has for
the nitrogen cycle is that it gives plants nutrients and minerals. Bacteria Bacteria are tiny little organisms that are all around us and is very important to the nitrogen cycle. It's very important because it changes nitrogen into different states which are nitrites and nitrates. Nitrites/Nitrates The process of turning ammonia into nitrites and nitrates is called
nitrification. First the bacteria consumes the ammonia to turn it into a nitrites. If there is a lot of nitrites it could kill animal life. Then the nitrites gets consumed by bacteria to turn into nitrates. Nitrates are very harmful too but the plants and algae use it as a energy supply and if there is more nitrates there will be more algae and plants. Plants/Algae Plants and algae are also very crucial to this cycle because they consume the harmful nitrates. Then they use the nitrates as food to gain energy. Carbon is very important to us and this cycle shows how plants use the carbon, how we use it, and the different form of carbon. Photosynthesis Photosynthesis is a process of the plant's chlorophyll to trap the sun's energy to make food, taking in water, and letting carbon dioxide enter through small holes of the leaf, then letting out oxygen to let us breathe . Respiration Respiration is process of breathing. Humans and animals take in the oxygen plants give off, and then give off carbon dioxide for plants. Diffusion Diffusion in the carbon cycle is a gas exchange between the ocean surface and atmosphere. It's when the carbon gets pushed up by currents, so that carbon can go back into the atmosphere or some carbon are used by algae and other plants. Consumption Consumption is animal life giving off carbon in the ocean or land. Then the carbon turns into carbon dioxide and plants will use it. Sedimentation When animals die they sink and take their carbon with them to form sediments, which are constantly being formed into rocks or land.Then the carbonates can redissolve in the depth of the ocean releasing carbon dioxide back to the air or water. Decomposition When organisms dies, decomposers break down dead material. But makes the nutrients available for living plants to take in, while releasing carbon dioxide from the dead organisms. Fossil Fuels Dead organisms and waste contain carbon in them, then the carbon can sink into the ground creating fossils fuels. But this process can take many year to develop. Some example of fossils fuel are gas, coal, and oil. Burning these fossil fuels can also release carbon dioxide into the atmosphere but increase the global temperature. Fires When fires start in the wild it burns down a lot of trees. Which can harm the process of the plants taking in the carbon dioxide. To make it worse fires would let off massive amount of carbon dioxide into the atmosphere. Humans/Deforestation Humans and deforestation has been included into the carbon cycle because humans have been burning carbon and releasing carbon dioxide back into the atmosphere and taking down important plant life that takes in the carbon dioxide and produces oxygen. 3 Starting Questions 1.)
