25
Matter
Anything that has mass and takes up space
26
Energy
the ability to do work
27
Open system
system in which both energy and matter are exchanged with the surroundings
28
closed system
system in which energy, but not matter is exchanged with the surroundings
29
atmosphere
mixture of gases that surround the planet, moon, or other celestial body
30
hydrosphere
portion of the earth that is water
31
geosphere
solid, mostly rocky part of the Earth; extends from core to crust
32
Biosphere
the part of Earth where life exists; including all of the living organisms
33
1rst Law of Thermodynamics
Energy is transferred between systems but never created or destroyed (think of a budget)
34
2nd Law of Thermodynamics
As energy transfers from system to system it becomes less organized with time (constantly becomes less useful/efficient)
35
Nitrogen Cycle
Moves through all the spheres; important for cells to build proteins and other cells; "fixed"-> needs to change for reactions
36
Carbon Cycle
building block of life; moves through all spheres; short-term movement and long-term storage
37
Phosphorus Cycle
building blocks of lipids and proteins; moves through all spheres EXCEPT atmosphere; concerning when it comes to environmental issues (Algae)
38
Water Cycle
necessary for life; cycles through atmosphere to the surface and back
39
Ecology
study of the complex relationships between living things and their nonliving, or abiotic, environment (connects life and earth science; studies organisms in their ecosystems)
40
ecosytem
community of organisms and their abiotic enviroment
41
carrying capacity
largest population that an environment can support at any given time
42
food chain
sequence of consumption of organisms through an ecosystem
43
food web
diagram that shows the feeding relationships among organisms in an ecosystem (multiple food chains)
44
parallels
any circle that runs E and W around Earth and that is parallel to the equator (this is a line of latitude)
45
Latitude
the angular distance N or S from the equator; expressed in degrees (think of a ladder); measured 0-90 degrees
46
Meridian
any semicircle that runs N and S around Earth from the geographic NP to the geographic SP (a line of longitude)
47
longitude
the angular distance E or W from the PM expressed in degrees (think long); all locations are labeled 0-180 degrees
48
Great Circle
any circle that divides the globe into halves or marks the circumference
49
Geomagnetic Poles
are on earth's surface where the magnetic fields run
50
magnetic declination
the angle between the direction of the geographic pole and the direction in which the compass needle points
51
Cartography
science of making maps
52
Remote Sensing
processes of gathering and analyzing information about an object without physically being in touch with the object
53
Cylindrical Projection
an image produced by projecting onto the surface of a cylinder
54
Azimuthal projections
an image produced by projecting onto a flat surface
55
conic projection
an image produced by projecting onto a conic surface
56
isogram
line on a map that represents a constant or equal value of a given quantity (all points along an isogram share the same value)
57
topography
the size and shape of the land surface features of a region, including its relief
58
contour line
line that connects points of equal elevation on a map
59
geologic map
designed to show the distribution of geologic features; shows the types of rocks found in a given area; overlayed on top of a base map that identifies the area
60
soil map
map that classifies, records, and describes the types of soil in an area
61
Accuracy
how close a measurement is to the truce value
