The parallel line of latitude that circumscribes the polar tundra zone is the Arctic Circle in the Northern Hemisphere and the Antarctic Circle in the Southern Hemisphere. These circles mark the approximate southern and northern boundaries of the tundra biome where the cold climate and limited vegetation characteristic of tundra regions are found.
It affects the climate because the climate zone is determined by the line of latitude.
A line of latitude that runs through Antarctica is 66.5 degrees. The Antarctic Circle is the South region that includes the South Pole and the Antarctic Circle.
The Arctic Circle
a latitude line is a line going from east to west. Just like the equator. the equator is a latitude line measuring at ) degrees latitude.
No, the international date line is a line of longitude, not latitude.
The equator is another name for the 0 line of latitude.
The African continent covers all latitudes between 37.34° North and 34.80° South. Any 'line' you draw, at any latitude within that range, traverses part of Africa.
the line 0 degrees latitude is called the
The arctic is the region of the world that has at least one 24 hour period per year that the sun does not rise and at least one 24 hour period per year where the sun does not go down. This is known as the arctic circle. As such, the arctic tundra is tundra located within the arctic region. Alpine is that area of the planet that is above the tree line. The tree line is determined by how cold a region gets. I believe that in order for trees to grow, the temperature must not dip below a certain temperature. Hence you will notice the tree line (or Alpine) level differs depending upon the variant temperatures in a particular region. In short, the colder the area, the lower the tree line. In the final analysis, the difference between the two types of tundra is a matter of location. Simplified, basically the alpine tundra is in the mountains and the arctic tundra is like the snowy icy place that we see on TV and think about mostly.
Tundra is located in the far north, above the tree line.
The main line of latitude is the Equator (zero latitude).
