The Earth is a sphere.
Looking at a sphere, the Earth, from the side, i.e. - the equator, eliminating each 'pole' position, which would appear as 'points', as opposed to 'lines', lines drawn at one degree intervals from top (North) to bottom (South), would number 178; given that there are 180 degrees from North to South.
Contour lines are a series of light brown lines drawn at intervals of 50 feet to designate their respective heights above sea level. They help to show the elevation and shape of the land on a topographic map.
Contour lines connect points of equal height, and show grades of hills, the closer together the lines the steeper the grade. The map legend should tell you the difference in elevation between lines, this could be in feet or meters
The lines that circle the Earth parallel to the equator are called latitude lines. They are measured in degrees north or south of the equator and help determine location and climate patterns on Earth.
Earth's parallels are called lines of latitude. They are imaginary lines that run parallel to the equator and are used to measure the distance north or south of the equator in degrees.
Straight lines on paper can be drawn by using the edge of a ruler (or straight-edge) and a pencil.
A square by definition has lines of symmetry. Therefore a square cannot be drawn without any lines of symmetry.
Yes. You can draw infinitely many straight lines from each point.
The straight line connecting the poles is the earth's rotational axis. The lines along the earth's surface from pole to pole are meridians or lines of longitude.
They are drawn on the earth as imaginary lines that run from east to west.
3 lines and one plane
line segments
1 straight line. An infinite number of curved lines.
If you're talking about straight lines (not curves) the answer is one.
i think just one line, as its defenition of straight line
Grid lines
In line mode the ruler is drawn as great circles (shortest possible path), which should be as a "crow flies". The ruler in Google Earth allows measurement of distances for a straight line or paths. Note for large distances (e.g. > 2000 miles) lines are drawn different than the lat-lon grid lines in Google Earth.
