The Arctic lowlands were formed by sheets of ice moving across the land, called glaciation. As the glaciers moved across the lowlands, they dug up sediment and gave the surface a rolling, corrugated look.Know More
The Arctic lowlands were formed by the movement of glaciers across the surface 7,500 years ago, according to The Canadian Encyclopedia. The lowlands in the Arctic Archipelago were formed not only by glaciation, but by faulting in the rock, which also accounts for the channels between the islands. Although the glaciers have long disappeared from the Arctic lowlands, the land still remains frozen for most of the year, making farming impossible. However, the lowlands are formed of sedimentary rock, which is rich in coal, oil, natural gas and limestone.
The Arctic lowlands include the Arctic Archipelago and are located in northern Canada, lying roughly between the northern Innuitian region and the southern Canadian Shield. The Arctic Lowlands along with the Arctic Coastal Plains make up a fourth of Canada. The fresh water in the Arctic lowlands are covered with ice 10 months of the year, only free of ice in July and August. Despite the severe cold, polar bears, muskox and arctic fox thrive in the lowlands.Learn more about Landforms
Streams form when downhill running water creates a channel capable of carrying water. Most streams begin as temporary rivulets that only have water after a rainfall.Full Answer >
Cliffs form through tectonic activity, water movement, weathering, erosion and glacier activity. Earthquakes and landslides also form cliffs. Cliffs tend to form on coasts, in mountainous areas, along rivers or as the walls of canyons.Full Answer >
The Center for Earth and Environmental Science describes that floodplains are formed as rivers erode their own banks. Floodplains are the flat lands that lie adjacent to a river; they encompass the area that floods when the river's water level rises. As the river flows, it washes material downstream. When a flood occurs, this material is resuspended in the water and added to the floodplain.Full Answer >
A strait is either formed by tectonic shifts or land that has subsided or been eroded. If a strait is created by people rather than geological forces, it is generally referred to as a canal.Full Answer >
