Exploring the Diversity and Characteristics of Grasslands

Grasslands are diverse ecosystems characterized by their grass cover and specific rainfall patterns, receiving 25-75 cm of rain annually. This amount prevents desert formation but is insufficient for forests, leading to cycles of drought and fire. North American grasslands experience extreme seasonal temperature changes, while African savannahs are hot with minimal rain. Soil quality varies, with North American grasslands having fertile soils, unlike the less fertile African soils, affecting the biodiversity in these regions.

What is the range of annual rainfall typically received by grassland biomes?

• 10 to 20 centimeters

• Over 100 centimeters

• 25 to 75 centimeters

• 80 to 100 centimeters

Which factor prevents forests from forming in grassland areas?

• Excessive rainfall

• High humidity

• Constant snowfall

• Cycles of drought and fire

How do North American grasslands differ from African savannahs in terms of seasonal temperature?

• Both have similar temperature patterns.

• North American grasslands have drastic seasonal changes, while African savannahs are consistently hot.

• African savannahs experience heavy snowfall, unlike North American grasslands.

• North American grasslands are always warm, while African savannahs are cold.

What is a notable characteristic of African savannahs during the summer?

• Scorching heat with little rain

• Cool temperatures

• Mild and wet conditions

• Heavy rainfall

How does soil quality affect grassland biomes?

• It has no impact on plant and animal life.

• It only affects the temperature of the biome.

• It determines the types of plants and animals that can survive.

• It causes grasslands to turn into deserts.
