Q. With reference to global Temperate Grasslands, consider the following statements:
1.They generally experience hot summers and exceptionally cold winters, with temperature drops hitting 0°F in peak winter seasons.
2.The annual precipitation ranges between 25 cm and 75 cm, falling significantly in the form of dew and snow.
3.The dominant natural vegetation includes sagebrush, perennial grasses, buffalo grass, and wild indigos.
Which of the statements given above are correct?
Answer: D
Notes:
Explanation:
- Statement 1 is correct: Unlike tropical equivalents, temperate grasslands experience sharp continental temperature extremes, where winters drop to 0°F or lower and summers routinely push past 90°F.
- Statement 2 is correct: They have lower overall moisture inputs than tropical savannas, receiving a limited 25 cm to 75 cm of precipitation annually. Because of the freezing winter regimes, a large portion of this moisture arrives via seasonal snow and morning dew.
- Statement 3 is correct: Due to the dry, cold periods, trees are rare. The biome is ruled by cold-tolerant, deep-rooted vegetation like perennial grasses, buffalo grass, clovers, wild indigos, and woody shrubs like sagebrush.
