They are used to measure distances north and south of the equator. The lines circling the globe in a north-south direction are called lines of longitude or meridians. Lines of longitude , called meridians, run in a north-south direction from pole to pole. What direction do longitude lines run? What is the 0 degree line of longitude called? What direction do lines of longitude go vertically or horizontally?
How do you remember vertical and horizontal? The terms vertical and horizontal often describe directions: a vertical line goes up and down, and a horizontal line goes across. You can remember which direction is vertical by the letter, "v," which points down. How do you know if longitude is east or west? If the number is negative, it represents south of the Equator. The line of longitude is read as 2. The coordinate for the line of longitude represents east of the Prime Meridian because it is positive.
Also, temperatures decrease as you move away from the equator. This is because the suns rays are dispersed over a larger area of land as you move away from the equator.
The length of the parallel increases as we move away from the poles towards the Equator because the Earth is spherical in shape and the circumference of the earth increases as we move towards the Equator.
This results in decrease in biodiversity towards the poles. You have an excellent question about biodiversity. Locations away from the equator will have cold winters that will slow growth for microorganisms, plants and animals. If you live on the equator you will experience the quickest rates of sunrise and sunset in the world, taking a matter of minutes. These places also have a constant twelve hours of day and night throughout the year, while north or south of the equator day length increasingly varies with the seasons.
Another argues that more solar energy is received around the equator, allowing for greater species richness. A third points out that equatorial tropics are the largest biome, so it makes sense that there would be more species. So the concept that the hottest place on earth is around the equator and the coolest is on the poles is wrong. Table of Contents.
