Question

Tundra vegetation is not found in ___________.
A) Asia
B) Europe
C) South America
D) North America

Answer 1

Hint: Dwarf shrubs, sedges and grasses, mosses, and lichens makeup tundra vegetation. Some tundra regions have scattered trees. The tree line or timberline is the ecotone (or ecological boundary region) that separates the tundra from the forest. The nitrogen and phosphorus content of tundra soil is high.

Complete answer:
The northern hemisphere of the Earth is home to almost all tundras. North America, Europe, and Asia are the three continents that make up the Arctic tundra, which is often referred to as a single entity. The Scandinavian and Russian tundras, on the other hand, are often referred to as tundra areas. The tundra in North America includes land in Alaska, Canada, and Greenland; the Scandinavian tundra in Norway and Sweden; and the Russian tundra in Russia.

Now let us look at the given options
A) Asia: This option is incorrect because a timberless region of tundra vegetation covers the subarctic north of Asia.
B) Europe: This option is incorrect because Arctic tundra can be found in North America, Europe, and Asia's far north.
C) South America: This is the correct option. The northern hemisphere of the Earth is home to almost all tundras. North America, Europe, and Asia. They are not present in South America.
D) North America: This option is incorrect because Tundra is located in the Arctic regions just under the ice caps, stretching across North America, Europe, and Asia's Siber.

Thus the correct answer is option ‘C’.

Note: The tundra is a treeless polar desert located mainly in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, as well as sub-Antarctic islands, at high latitudes in the polar regions. Winters in the area are long and dry, with months of complete darkness and bitterly cold temperatures.
