26
Define anthropogenic:
Human-made
27
What does coal release when burned?
Mercury
28
Coal forms in layers known as___?
Coal seams
29
Combustion of all fossil fuels always release ____ and ____.
Carbon dioxide, water
30
Name four carbon sources:
Deforestation, respiration, decaying organic matter, volcano eruptions
31
What is a sink?
Takes out of the atmosphere
32
What is a source?
Put into atmosphere
33
Name four sinks:
Oceans, Animals eating plants with carbon, photosynthesis, becoming fossil fuels,
34
Phytoplankton takes in CO2 and releases____.
Oxygen
35
A greenhouse gas absorbs radiation and re-emits it as____.
Infrared
36
What is infrared?
Heat
37
The above reaction traps energy that potentially warms the earth. This is known as the ___ effect.
Greenhouse
38
`Essential question
Does the greenhouse affect without humans.
39
True/False: as CO2 levels in the atmosphere increase the temperature increases.
True
40
Can carbon be destroyed?
No, only sequester it
41
If there was no CO2 in the world we would_____.
Freeze
42
Do CO2 level fluctuate naturally?
Yes
43
What bacteria turns nitrogen to ammonium?
Nitrogen fixing
44
What bacteria turns ammonia to nitrates?
Nitrifying
45
What bacteria turns nitrates to ammonium?
Denitrifying
46
What is the biochemical cycle?
Natural recycling of earth's elements
47
What is transpiration?
When plants absorb water and release it into the atmosphere as water vapor. Transpiration-plants
48
What is precipitation?
Refers to rain or snow that falls to the earth's surface. | Precipitation-rain or snowfall
49
What is infiltration?
The movement of surface water into rock or soil through cracks and pore spaces. Infiltration-water into rock or soil
50
What is condensation?
The change of physical state of water from its gaseous phase to its liquid phase. This is how clouds form. Condensation- gas to liquid
51
What is evaporation?
When water returns to the atmosphere from the soil, lakes and streams by turning into its gaseous form. Evaporation-water vapor and clouds
52
What is a runoff?
When the land cannot absorbs all the rain. The excess water then flows over the surface into lakes and streams. Runoff-extra water ends up in lakes, streams, and oceans.
53
What are the types of precipitation?
Rain, freezing rain, sleet, snow, hail
54
Precipitation starts as ____ before it goes through warm air.
Snow
55
What are the types of clouds? Describe them
Cirrus-feathery/thin Stratus-Layered Cumulus-Fluffy
56
What is a nimbus cloud?
Rain cloud
57
What is an aquifer?
An underground layer of water-bearing permeable rock or unconsolidated materials (gravel, sand, or silt) from which groundwater can be extracted using a water well.
58
An artesian well does not need a pump why?
Because the water has no where to go but up because of surrounding pressure.
59
What is distillation?
The technique of using heat to separate compounds.
60
What two minerals is carbon found?
Diamond and Graphite
61
What is a hydrocarbon?
A compound consisting entirely of hydrogen and carbon.
62
Where are the majority of hydrocarbons found on earth?
In crude oil
63
What are the two main ocean carbon sinks?
The water and Phytoplankton
64
What is phytoplankton?
Phytoplankton are tiny oceanic organisms that undergo photosynthesis. They are the "grass of the sea".
65
Trapped energy that can potentially warm the earth is called _____.
The greenhouse effect
66
Why does atmospheric CO2 trap heat?
CO2 absorbs in the same range of the spectrum that Earth emits in.
67
Can the concentration of anthropogenic atmospheric CO2 effect climate?
Yes, if carbon dioxide increases enough, the earth's temperature could increase.
68
Is the greenhouse effect a natural process?
Yes-it occurs with or without the presence of mankind.
69
What is the nitrogen cycle?
Refers to the constant motion of Nitrogen in various forms among the hydrosphere, the atmosphere, the geosphere and the biosphere.
70
What percentage of the earth's atmosphere is nitrogen gas?
78%
71
Water cycle summary: Sources
Evaporation-water vapor and clouds Transpiration-plants Condensation- gas to liquid
72
Water cycle summary: Sinks
Precipitation-rain or snowfall Infiltration-water into rock or soil Condensation-gas to liquid Runoff-extra water ends up in lakes, streams, and oceans.
