kilo
lines of latitude
lines that measure north and south of the equator.
Key or Legend
lists and explains all the symbols on a map.
longitude
measures distances east and west of the prime meridian.
one-thousandth times the base unit (or base unit divided by 1000)

when we measure distances in every day life, we use distances such as...
0.025 liters
25 milliliters equals how many liters
same, easy
This system is in place so that scientists all over the world use the _____ units to measure things, and because the SI is _____ to use.
equator
breaks the Earth up into the Northern and Southern hemispheres.
0.5 km
500 meters equals how many kilometers
Map
A flat model of all or part of Earth's surface
Globe
A spherical representation of Earth's entire surface as seen from space.
longitude
The Prime Meridian is a line of...
Greenwich, England
The Prime Meridian passes through here.
metric system
The SI system is very similar to this
unit
a scale can be written as (1:200,000)
graphic scale
a scale written like a number line
International System of Units (SI)
a system scientists use to measure and describe objects
equator
all lines of longitude meet here.
decimal place
because you are always multiplying or dividing by multiples of 10, you can simply move the ______________ to the right or to the left for each zero in order to convert from one measurement to another
one-hundredth times the base unit (or base unit divided by 100)
centi
one-tenth times the base unit (or base unit divided by 10)
deci
10 times the base unit
deka
Hemisphere
half of Earth's surface.
100 times the base unit
hecto
1.350kg
how many kg does 1350 grams equal
meter (m)
how the length is measured in the SI system
Kilogram (kg)
how the mass is measured in the SI system
Kelvin (K)
how the temperature is measured in the SI system
second (s)
how the time is measured in the SI system
liter (L)
how the volume is measured in the SI system
scale
relates the distances on a map to the distances on Earth's actual surface.
models
representations or descriptions designed to show an object system or concept
equator
the imaginary line that circles Earth halfway between the North and South Poles.
90 degrees North
the latitude of the North Pole.
25,000
the scale on a map say 1:25,000. What would the unit measure on the actual Earth? (This doesn't say miles or feet - it says units. That way you can measure in whatever units you want to. So if the map scale shows 1cm the answer would be in cms.)
equator
the starting line for measuring lines of latitude.
geology
the study of how rocks from
astronomy
the study of space and how the planets orbit the sun
oceanography
the study of the earths oceans and how organisms survive in the deep ocean
meterology
the study of the weather and the atmosphere and what gasses are found in different layers of the atmosphere
degrees
units scientists use to measure distances around a circle.
