Abundant water resources
D
Correct answer
Explanation
Arid lands are characterized by a lack of water resources.
Which of the following is a characteristic of tundra vegetation that contributes to its resilience?
-
Deep root systems
-
Short growing season
-
High species diversity
-
Large leaves
B
Correct answer
Explanation

Salt marshes are often dominated by which type of vegetation?
-
Coniferous Trees
-
Deciduous Trees
-
Shrubs
-
Salt-Tolerant Grasses
D
Correct answer
Explanation

What is the vegetation of the Deccan Plateau?
-
Tropical rainforest
-
Tropical deciduous forest
-
Temperate rainforest
-
Temperate deciduous forest
B
Correct answer
Explanation

Which type of forest is most effective at removing pollutants from the air?
-
Coniferous forests
-
Deciduous forests
-
Tropical rainforests
-
Temperate forests
A
Correct answer
Explanation
Coniferous forests are most effective at removing pollutants from the air because they have a high density of leaves and needles, which provide a large surface area for pollutants to be trapped.
