Since the earth is on an axis its impossible to go in a straight line because the earth is round. So the lines get smaller because of the axis and the tilt and some of it has to do with the earth being round (like most planets...=)
Yes, the circles formed by the lines of latitude get smaller as they get closer to the North and South Poles. This is because the lines of latitude are parallel to each other, so as they approach the poles, they shrink in size until they reach a point at the poles themselves.
Because the parallels of latitude are imaginary lines drawn on the Earth's surface, and, you may have noticed, cross sections of the Earth itself decrease in diameter as the cutting plane moves toward the poles.
Meridians converge at the poles and intersect the equator at 90 degrees. They are all great circle lines called lines of longitude. The equator is a line of latitude and the only line of latitude that is a great circle line. As you move away from the equator the lines of latitude describe smaller and smaller circles round the planet as you approach the poles.
As lines of latitude get closer to the poles, they get shorter in length and converge towards a point at the poles. This is because the Earth is a sphere, and the lines of latitude represent circles around the Earth. The lines of latitude are farthest apart at the equator and gradually come together towards the poles.
Lines of latitude, or parallels, are circles that run parallel to the equator. As you move towards the poles, these circles decrease in size because they represent the curvature of the Earth. The Earth is a sphere, and thus the circumference of each latitude line diminishes as you approach the poles, resulting in smaller and smaller circles. This geometric property is a consequence of the Earth's round shape.
Lines of latitude are parallel circles that run east-west around the Earth, with the equator being the widest at 0 degrees latitude. As you move toward the poles, these circles get smaller because the Earth's surface curves inward. This results in a decrease in the circumference of each latitude line, making them progressively smaller as they approach the poles. This geometric relationship is a consequence of the Earth's spherical shape.
Lines of latitude are horizontal and run parallel to the poles
Lines of latitude decrease in number as one moves toward the poles because they represent the angular distance north or south of the equator, which is at 0 degrees latitude. As you approach the poles, these lines converge, leading to a reduction in the number of lines within a given distance. This convergence reflects the Earth's spherical shape, where the distance between each line of latitude narrows as you move away from the equator toward the poles. Thus, while the lines are evenly spaced at the equator, they become closer together as they reach the poles.
longitude
No, this statement is false. Meridians are lines of longitude that converge at the poles, meaning they touch at the poles. Lines of latitude, however, like the equator, never intersect and are always parallel to each other.
Latitude lines
No they do not
