upsc-p1-geography-biogeography-soils MCQ - Practice Questions with Answers

Solve 2 upsc-p1-geography-biogeography-soils questions for RAS/RPSC preparation.

Practice questions

Q1Consider the following statements about world biomes: 1. Tropical rainforest combines rapid nutrient cycling with strongly leached soils. 2. Tropical savanna has distinct wet and dry seasons. 3. Tundra is characterised by permafrost and tall coniferous trees. Which of the statements given above are correct?

A 1 only

B 2 and 3 only

C 1 and 2 only

D 1, 2 and 3

Explanation

Statements 1 and 2 are correct. Rainforest nutrients cycle rapidly even though its soils can be heavily leached, while savanna has marked wet-dry seasonality. Tundra has permafrost, mosses and lichens but no tall trees, making Statement 3 incorrect.

Q2Consider the following statements about natural vegetation: 1. Mangroves occur on tidal, saline and muddy coasts and deltas. 2. Every grassland in India is a degraded forest. 3. Montane vegetation can change sharply with altitude. Which of the statements given above are correct?

A 1 and 3 only

B 1 and 2 only

C 2 and 3 only

D 1, 2 and 3

Explanation

Statements 1 and 3 are correct. Mangroves are salt-tolerant forests of tidal muddy coasts, and montane belts change with altitude. India also has natural grasslands, so treating every grassland as degraded forest is an ecological error.
