E
Describe the Greenhouse Effect
E from the sun in the form of visible and UV light arrives at the earth and enters the atmosphere. That radiation is absorbed by the surface of earth and other objects. The E is re-emitted by the earth's surface as infrared light which cannot pass through the atmosphere like UV can. It get trapped and absorbed by the greenhouse gases in the atmosphere. Later the greenhouse gases get released and some go into space and some return to earth and warms the planet.
Benefits of runoff
Helps water travel to different locations, picks of sediment and nutrients and disperses it
What are the effects of too much GHG
Increase temp, stronger storms, hurricanes, tornadoes, and higher sea levels b/c polar caps melt which leads organisms losing of habitat and people moving further inland
When precipitation hits the ground, what two options does it have
Infiltration or runoff
Convection
Involves the movements of fluid or air
What role do GHG play for our planet
Need it to warm the planet. It becomes a problem if there is too much or too little
Describe the carbon cycle
Normal processes like breathing and geological activities release CO2. Trees/plants take in CO2 during photosynthesis. Oceans absorb some. Animals eat plants and die. Decompose-rs destroy any remains and return it to the soil. Over millions of years, those materials in the soil will become rock and compressed into fossil fuels like coal and oil.
Infiltration
Occurs when surface water enters the soil
Transpiration
Plants losing water through its leaves
What are the characteristics of soil what effect infiltration rate
Porosity- amt of water absorbed and permeability- how fast can water be absorbed
How does runoff cause erosion
Sediment travels and acts as sandpaper and causes erosion to the land
What are the con of runoff
Takes away nutrients from plants/animals that need it in the case of deforestation. Can pick up chemicals and pollutants and put them into other bodies of water
What is the carbon cycle
The carbon cycle describes how carbon molecules move between the living and nonliving world.
Hydrosphere
The layer of the earth where water is present
What problem happens in the ocean when there is too much CO2 in the atmosphere
Too much carbonic acids production which increases the acidity of the ocean causing the death of many marine life
Conduction
Transfer of E through physical contact of a warmer object to a cooler object
Groundwater
Water could absorb into the ground or into plants
What are the unofficical other part of the water cycle
What happens after water has fallen. Runoff, groundwater, and transpiration
What is deposition and how does runoff play a hand in it
When nutrients are carried from one place to another. In runoff, the water is the one transports that nutrients
Ocean acidification
When the ocean becomes acidic
Runoff
When water flows along the surface into lakes, rovers, and streams
Three phases of water cycle
evaporation, condensation, precipitation
