Charts and Maps Flashcards
Charts and Maps (and previous lessons)
two dimensional representation of the Earth’s 3D surface
Maps and Charts
show the land feature of the Earth
Maps
display the ocean and their features
Charts
Maps and charts are made by
projecting the features of the
earth’s surface together with
reference lines onto a surface
to produce a ___________
chart projection
The earth is essentially a sphere, and a circle drawn around the
center of the earth perpendicular to its axis of rotation is the
equator
True or False:
0 degrees latitude - Equator
True
True or False
0 degrees longitude - equator
False
North Pole is __ degrees north of Equator
90
South Pole is __ degrees South of the equator
90
show how deep the water is
Bathymetric charts
show what the seafloor actually looks like in terms of shape and structure.
Physiographic charts
True or False:
Line of longitude forms a progressively smaller circle
False
it must be line of latitude
set the boundaries of what is called the tropics
Tropics of Cancer (23.5 degrees N)
Tropics of Capricorn (23.5 degrees S)
Reference lines (latitude) that marks the boundaries of the polar regions
Arctic Circle and Antarctic Circle
Latitude lines are sometimes referred to as
Parallels
lines that run in an east-west direction
Latitude
measures distance North or South from the equator
Latitude
True or False:
Latitude lines are parallel to one another and can never meet
True
Latitude Lines cross the ______ at right angles
Prime meridian
lie in planes that cross the earth’s axis at right angles
latitude
longest latitude line
Equator
get shorter towards the pole, with only the equator, the longest, a great circle
latitude
lines of longitude are also known as
meridians
are at right angles to the latitude lines, extending from the North Pole to the South Pole.
