Parallels and meridians are the lines that make up the Earth's grid system for navigation and mapping. Parallels are lines of latitude that run horizontally, while meridians are lines of longitude that run vertically. They intersect each other at right angles, or 90-degree angles, creating a coordinate system that helps in pinpointing locations on the globe. This grid system is essential for navigation, geography, and various scientific applications.
What else can I help you with?
Why aren't all parallels equal in length like meridians are?
There's a simple answer: The earth is a sphere and the parallels are, well, parallel to each other. So obviously the ones closer to the poles are shorter than the ones closest to the Ecuator. As for the meridians all meet at one point ehich are the poles, so they are all the same length.
Do all parralles and marideans meet at angles other than 90 degrees?
Meridians and circles of latitude (parallels) will meet at an angle of 90 degrees at the equator only. All other crossings will not be 90 degrees as they converge to the two poles. To correct the previous answer: All meridians crossing parallels are not at 90 degrees due to the curvature of the spherical triangle's three sides. However, they will all cross at 90 degrees as viewed each from a specific point in space which would be perpendicular to the earth's N-S axis and directly over (in line) with the meridian.
If you have a triangle with one angle 110 degree's and the other two angles equal 120 degree's What are the other 2 angles?
A triangle has only three angles and they sum to 180 degrees.
If home plate has four 90 dagree angles what is the measure of the other two angles?
If it has four 90 degree angles, than it's a square, and therfore only has four angles.
When the sum of two angles 90 the angles are classified as?
When the sum of two angles is 90 degrees, the angles are classified as complementary angles. This means that each angle, when added to the other, results in a right angle. For example, a 30-degree angle and a 60-degree angle are complementary because their sum is 90 degrees.
Are all parallels and meridians meet at angles other than 90 degrees?
yes
A basic geography questions - Do all of the parallels and the meridians cross each other at right angles on both the globe and Mercator?
On a globe, parallels and meridians do not intersect at right angles; only the equator and the prime meridian intersect perpendicular to each other. On a Mercator projection map, the meridians appear as straight lines converging at the poles, while the parallels are equally spaced horizontally, giving the illusion that they intersect at right angles, when in reality that is not the case.
Do all of the parallels and meridians cross each other at right angles on both the globe and the Mercator?
On a globe, parallels and meridians meet at right angles only at the equator and the poles. On a Mercator projection map, all meridians intersect the equator at right angles, while parallels intersect meridians at right angles throughout the map.
On what map projection do both meridians and parallels appear as straight lines intersecting each other at right angles?
Cylindrical
What are the major differences between parallels and meridians?
Parallels are lines of latitude that run east-west around the globe, while meridians are lines of longitude that run north-south. Parallels are always equidistant from each other, while meridians converge at the poles. Parallels help locate positions north or south of the equator, while meridians help locate positions east or west of the Prime Meridian.
What is the difference between parallels and meridians?
Parallels, as the name inplies, run parallel to each other in an east-west orientation. Meridians run through both poles, and so cannot be parallel.

Differences between parallels and meridians?
-- Parallels are associated with latitudes. Meridians are associated with longitudes. -- Parallels are parallel, and no tweo parallels intersect. All meridians intersect all other meridians, at two places. -- Every point on a parallel has the same latitude. Every point on a meridian has the same longitude. -- Every parallel in the same hemisphere has a different length. Every meridian on Earth has the same length. -- Every parallel is a full circle. Every meridian is a semi-circle. -- Every parallel crosses all longitudes. Every meridian crosses all latitudes. -- The distance between two parallels is the same at every longitude. The distance between two meridians depends on the latitude where it's measured. -- To cross all parallels, you only have to travel 12,000 miles. To cross all meridians, you have to travel 24,000 miles.
What is the difference degrees and meridians?
Meridians are lines on a sphere (or other geometric solid) all of which go through the poles. Degrees are a unit of measurement of angles and temperature and concentration, and some other things. As a unit for measuring angles, meridians are measured in degrees. There are 360 degrees in a complete circle.
What are meridians and parrells?
lines of latitude are parallels and lines of longitude are meridians. latitude lines are circles around the earth running east west (like equator) longitude lines run north - south and they meet at two spots, the north pole and the south pole. Meridians also determine the time at a location on the earth.
What type of projection is a mercator world map and what sets it apart from other projections?
The Mercator projection has straight meridians and parallels that intersect at right angles. Scale is true at the equator or at two standard parallels equidistant from the equator. The projection is often used for marine navigation because all straight lines on the map are lines of constant azimuth.
