Name the 3 basic units of measurement and what they measure - answer1. Meter:
length
2. Liter: volume
3. Gram: mass
10 - answerThe metric system increases and decreases by units of...
Significant numbers are... - answerall non zero numbers, zeros between numbers, and
zeros to the right of the number.
ex 0.01230 sig numbers are: 1230
___ variable goes on the x axis
___ variable goes on the y axis - answerindependent variable goes on the x axis
dependent variable goes on the y axis
Independent variable - answerthe variable being manipulated by the experiment
Dependent variable - answerthe variable that may change because of the independent
variable
Mean - answeraverage
add up all numbers and divide
Median - answerthe "middle" value in the list of numbers in numerical order
Mode - answerNumber that appears most often
Range - answerDifference between highest and lowest number
Igneous Rock - answerformed when hot magma cools beneath the ground
or
lava cools above the ground
forms crystal like/ glassy rocks
, ex: granite and pumus
Sedimentary Rock - answerChanged by pressure
does not involve heat
Usually near water/ involves water
sometimes contain fossils
forms from previously weathered and erroted material which may have been igneous,
sedimentary, rock metamorphic rock.
ex: dolemite, limestone
Metamorphic Rock - answerHas been changed by great heat and pressure
altered, partially remelted
ex: slate, marble
Petrology - answerthe study of rock
Geology - answerthe study of earth and it's rocks
Plate tectonic theory - answerLithosphere is made up of major and minor plates
Sit on viscous (thick fluid) part and move with it
There types of plate boundaires - answer1. Transform boundaries: they slide past each
other causing friction/ earthquakes
2. Divergent boundaries: two plates that pull away from each other/ creates new crust
3. Convergent boundaries: plates push into each other/ one goes under called
subduction
Lines of longitude and latitude track - answertime and location
Troposphere - answerWeather occurs in the
Latitude - answerWhat indicates climate
3 states of water - answersolid (ice), liquid, or gas (vapor).
The atmosphere is composed of - answer78% nitrogen
21 % oxygen
List earths atmosphere layers in order from lowest to highest. - answerTroposphere
Stratosphere
Mesosphere
Thermosphere
Exosphere
