Lines of longitude run vertically from the north pole to the south pole. The Prime Meridian (zero longitude) runs through the Greenwich Observatory, London, England. Lines that run parallel to the Equator (zero latitude) are lines of latitude.

What do you call the lines that make up the grid on your maps?

Those are called latitude and longitude lines. Latitude lines run east-west, measuring north and south of the Equator. Longitude lines run north-south, measuring east and west of the Prime Meridian. Together, they help determine specific locations on a map.


Is the equator 0 degrees longitude?

Because that's its definition. When the scale of latitude was invented, zero could have been placed anywhere. For example, the south pole might have been defined as the zero, and latitudes on earth would range from zero up to 180° at the north pole. But instead, it was decided to put zero in the middle, and call the south latitudes negative and the north ones positive.


Is there a natural baseline in latitude?

Longitude goes up and down so really is not affected by the equator (except that all lines of longitude run perpendicular to the equator), all lines of longitude are aligned from the north and south poles. But the equator does serve as a sort of "baseline" or zero for the lines of latitude, which run east to west. When measuring using latitude, the equator is "zero", as you go further north, you measure with increasing numbers. The same is done when measuring south, so to tell one from the other, the words north and south or the letters "n" and "s". for example, 5'n, 15's, 50'n.


What do you call the imaginary line that divides the north and south halves of earth?

The equator divides the earth between the Northern Hemisphere and the Southern Hemisphere


What circles the earth to show latitude?

The equator circles the Earth horizontally at 0 degrees latitude to divide the Earth into northern and southern hemispheres. Similarly, lines of latitude (parallels) run parallel to the equator and show the distance in degrees north or south of the equator.

What do you call the lines on a map or globe that meet at the north and south poles?

Meridians - or lines of longitude.


Distance north or south on a map can be measured by which of these?

Latitude measures North or South of the Equator in degrees. 0° is the Equator, and 90° N (or +90°) is the North Pole, and 90° S (or -90°) is the South Pole. Each degree of latitude is about 69 miles (or 60 Nautical Miles). Longitude lines (which run north and south, but measure east/west) get closer together as you approach either pole.

What splits the sky in two from north to south?

There is an imaginary plane through the Earth that splits the world into "north" and "south". The circle around the Earth where that plane meets the Earth's surface is called the "equator". In astronomy, we extend that plane into space; this is the "celestial equator". With geography on the Earth, we measure this in latitude north or south of the equator. In astronomy, we call it "declination", but it's the same idea.

What do you call the line that divides the globe into 2 spheres?

If you are talking about the line that separates the north hemisphere and the south hemisphere, it is the equator.


What are parallels?

Parallel chords are A sequence of chords consisting of intervals that do not change as the chord moves. For example the chord of C (C,E,G) would be parallel to a following chord ofF (F,A,C)
