When you cross the International Date Line heading east (toward America), the clock moves back 24 hours, or one entire day. When you go west (toward Asia), the calendar moves ahead one day.
What is a Topographic Map?
Maps that use isolines to represent constant elevations. If you took a topographic map out into the field and walked exactly along the path of an isoline on your map, you would always stay at the same elevation.
What is a Contour Interval?
On a topographic map, tells the difference in elevation between adjacent contour lines.
What is an Electromagnetic Spectrum?
All of the frequencies or wavelengths of electromagnetic radiation
What is a Contour Line?
A line on a topographic map that connects points of equal elevation
What is Frequency?
How many wave peaks pass a certain point per given time
