Answer Details

(a) Four differences between Tropical Grassland and Temperate Grassland:

(Also acceptable: savanna supports big game/wildlife, steppe is a major zone for wheat and cattle/sheep ranching.)

(b) Climate of the Tropical Grassland (Savanna):

• High temperatures throughout the year, averaging about \(24^{\circ}\text{C}\), with the hottest period just before the rains.
• Distinct wet and dry seasons: the wet season comes with the overhead sun, the dry season when the sun is overhead in the opposite hemisphere.
• Moderate rainfall, about \(500\text{ to }1000\text{ mm}\) a year, brought by convectional storms in the wet season.
• A relatively small annual temperature range but a marked contrast between the rainy and dry periods; skies are cloudy in the wet season and clear and dusty (harmattan) in the dry season.
