What is a tundra characterized by?

  1. a. High levels of precipitation

  2. b. Year-round warm temperatures

  3. c. Absence of wind

  4. d. Frozen soil and low precipitation

The correct answer is: d. Frozen soil and low precipitation

A tundra is a type of ecosystem found in colder regions, such as the Arctic and parts of high mountain areas. It is characterized by extreme cold temperatures and a lack of trees due to the frozen soil. The tundra is also known for its low levels of precipitation, as moisture in the air often freezes before it has a chance to fall as rain or snow. This rules out options A and B, which both mention high levels of precipitation and warmth, respectively. Option C is incorrect because the tundra is often subjected to strong winds due to its open, treeless landscape. Therefore, the correct answer is D.
