Longitude & Latitude
They connect points of this
What is equal value?
Water always naturally flows in this direction
What is downhill?
Lines of latitude never do this.
What is touch?
Where do longitude lines meet?
at the poles?
This is an isoline that connects points of equal temperature
What is an isotherm?
Contour lines make a V when they cross a stream. Water in a stream will flow out of or into the V
What is out of the V?
The B'ville map you looked at is called this type of map
What is a topographic map?
Latitude lines are drawn horizontally or vertically?
What is horizontal (flat) and parallel?
This is an isoline that connects points of equal air pressure
What is an isobar?
What compass direction is the top of a map?
What is North?
A degree of latitude or longitude has this many minutes
What is 60?
Time zones are this many degrees of longitude wide.
What is 15 degrees?
Circles on a topo map show this landform

True or False - the interval between all isolines on a map is the same
What is true?
A stream has a source at an elevation of 1,500 meters. It ends at a lake that has an elevation of 1000 meters. If the lake is 100 kilometers away from the source, what is the average gradient of the stream?
1) 15 m/km 3) 5 m/km
2) 3.5 m/km 4) 10 m/km
What is 3?
The formula for gradient
What is Δ field value÷ distance ?
They cannot do this.
What is touch or cross?
Putting scrap paper on a mop, marking contour lines and their elevations, plotting points and connecting them with a line creates this?
A profile
A side-view of a natural feature created by graphing its elevations at certain points.
What is a topographic profile?
