Answer: The watersheds of creeks and rivers are separated from each other by land forms of higher elevation called ridge lines or mountain divides.
Explanation: drainage divide. Definition English: Water divide a k a Drainage divide, Because water runs downhill, topography defines the boundary of a watershed ridges or high points in a landscape form the line between one watershed and another.
Hope this helps :3
Answer:
Iceland was not considered as a wasteland by the Vikings that settled in, but the name was given on purpose so that they avoid competition for it.
Explanation:
The Vikings were the first people to reach Iceland. They traveled from their homeland in Scandinavia into the unknown ocean water and eventually managed to reach a large island. Once they got to the island, they made it their base, but also sent expeditions further west, reaching Greenland, and even the North American mainland.
Being aware that there are other groups of Vikings waiting to set sail westward, the first group decided to trick them in order to get better land for themselves. This was done by naming the two large islands they discovered. The green and much more suitable for a living have been named Iceland, while the one covered with ice and much harsher was named Greenland. This made the later groups of Vikings think that Greenland is the better option and they got tricked. Iceland was not a wasteland by any means. It had a lot of timber, freshwater, and an abundance of fish and marine mammals as a food source.
Constructive plate boundaries
1) Convection currents in the mantle move the plates
2) 2 plates of oceanic crust diverge/pull apart e.g. North American and Eurasian plates.
3)
The rising magma forces the ends of the plate to push up and buckle.
This creates tensional cracks on the underside of the plates.
4) Magma is squeezed into the gap between the two plates and is cooled by the ocean to form new, solidified rock/basalt.
5) Rising magma forces its way through the tensional cracks and forms sub-marine shield volcanoes on the ocean floor.
6)
With repeated eruptions over millions of years they can grow until
they break the surface of the ocean and become volcanic islands e.g.
Iceland.
They come from ice sheets, ice caps, glaciers, icebergs, bogs, ponds, lakes, rivers, and streams.
The equator and prime meridian meet closet to the continent of Africa.
