100
the difference between each contour line on a topographic map
What is contour interval
100
angular distance north or south of the equator
What is latitude
100
Most acturate map of the Earth
What is globe
100
thought to be the source of Earth's magnetic field
What is liquid outer core
100
approximate age of the Earth

200
every 5th contour that is usually labelled and bolder on a map
What is index contour
200
angular distance east or west of the prime meridian
What is longitude
200
this occurs as you move away from areas that are touching a globe when constructing a map projection
What is distortion
200
Thinnest layer of Earth's interior
What is crust
200
name given to early planet-like objects that eventually formed our current planets
What are planetessimals
300
contour lines form Vs that point this direction when they cross a stream
What is upstream
300
0 Degrees latitude
What is equator
300
Most accurate projection for middle latitude locations. Made by placing a cone shaped paper over a globe to make this projection
What is Conic
300
these have allowed scientists to "see" Earth's interior layers
What is seismic / earthquake waves
300
thought to be the maximum interior temperature of Earth
What is 13,000 F
400
all elevations on a topographic map are referenced from this
What is mean sealevel
400
Maximum number of degrees you can travel in longitude from the Prime Meridian
What is 180
400
Projection where latitude and longitude lines are stretched to be perpendicular to each other. Maximum distortion at the poles
What is Cylindrical or Mercator
400
The crust and upper mantle combined form this layer
What is lithosphere
400
name of the process that formed our solar system
What is nebular hypothesis
500
a place on a topographic map that has its exact elevation printed and also has a real brass plate anchored in the ground in the real world
What is benchmark
500
Every 15 degrees of longitude is also this
What is a time zone
500
Projection used to construct topographic maps
What is azimuthal
500
name of the silly putty layer that Earth's outer most layers rest upon
