True North
it is the actual North Pole
Where are the geographic poles?
at either end of the Earth axis and used as a reference point when describe direction and location on Earth.
Why are lines of latitude and lines of longitude are alike?
They have to deal with the same subject. They are both lines. Both help you find a destination on the Earth.
Why are lines of latitude and lines of longitude are different?
They go different ways around the Earth. Longitude measures east and west. Latitude measures north and south.
What do you use the magnetic compass to find?
directions on Earth because a compass always points north than you know where east, west, and south are.
The difference between true north and magnetic north are
they do not line up
True North
-The direction to the geographic North Pole. Is lined up with the axis.
Magnetic North
Is not lined up with the axis. Is lined up with the magnetic field.
Why do the lines of latitude and longitude help you find locations on the Earth's surface?
when you line them up it shows how many degrees it is in the world. They pin point all the locations on the Earth because the Earth is divided in to a grid.
Why do you need to know an area's magnetic declination
because this will help you to find true north.
What is most often used to map the United States
conic projection
Five things found on a map
1. title
2. Compass rose
3. scale
4. legend
5. date
How can a GPS can help you find your location on Earth?
by typing your location and it atomically goes there.
When is radar useful?
when mapping areas that tend to be covered in clouds because you can still see
The type of map projection I would use to map a landmass that has more area from east to west than from north to south would be?
conic projection because a map projection is made by moving the surface features on the globe to cone.
7. A map of North America would be small or large scale.
large
A map of a city would be large or small scale.
small

What is an index contour?
a heavier contour line that shows a change in elevation.
What do Topographic maps represent?
the Earth's surface by using the same symbols and colors to represent the Earth's surface. The key shows what each surface on the map is. Like the lines represent roads, dotted lines represent trails and green represents woods.
How does the relief of an area determines the contour interval used on a map?
showing the difference in elevation between highest and lowest points. The relief shows large contour intervals or small contour intervals depending on the area.
The rules of a contour lines are
show how tall or low land is.
The highest point on a hill is not represented by a contour line because
the highest point of the hill is a closed circle. Contour lines don't cross and represents one elevation.
True North
-it is the actual North Pole.
Magnetic North
not the true north pole.
Equator
imaginary line that the Earth tilts. 0 degrees latitude
Prime Meridian
0 degrees longitude
the difference in elevation between one contour of and the next.
Contour Interval
Index Contour
on a map, darker, heavier contour line that usually every fifth line and that indicates a change in elevation.
The distance in degrees east or west of the prime meridian.
Longitude
Widely spaced contour lines indicates
gentle slope
The most common map projections are based on three geometric shapes.
Cylindar, Cone, Square
cylindrical projection is
distorted near the poles.
What is Scale
Is the relationship between the distance on a map and the actual distance on Earth.
Is the height of an object above sea level.
elevation
Four methods that modern map makers use to make accurate maps:
1. Remote sensing - the process of gathering and analyzing information.
2. Satellites - give detailed images of the Earth's surface.
3. GPS - can hel find where you are on Earth.
4. GIS - computerized system that allows a user to enter different types of
Why is a map legend important?
Because it's a list of symbols used in the map and their explanations.
Greenland appear so large in relation to other landmasses on a map using a cylindrical projection because
it distorts areas near the North and South Poles.
The function of contour lines on a topographical map are used to
show elevation.
GPS can find your location on Earth because
it's a system of orbiting satellites that send radio signals to receivers on Earth.
A GIS is a geographic information system that shows you
different types of information in an area.
different different different ahh
hi
different? hi? fart? poo? IILL? no? yes? pee? done?
yay!
