Final answer:
Major grassland regions are found in the central or eastern parts of continents due to factors such as rainfall patterns and geographic features that influence climate, like mountain ranges.
Step-by-step explanation:
Most of the world's major grassland areas tend to be located in the interior regions or toward the eastern side of continents, typically in areas where there is enough rainfall to support grasses but not enough for forests.
Grasslands generally avoid coastal areas where forests are more likely due to higher moisture levels, and they are less common in western regions of continents where dryer conditions prevail due to rain shadows or continental climates.
In North America, the Great Plains span the central part of the continent. In South America, the Pampas are located in the central-eastern part, in countries like Argentina and Uruguay.
Africa's Savannas are found mainly in the eastern and southern parts, while the Eurasian Steppe stretches across the central and eastern parts of the continent.
Australia has grasslands in the eastern and northern parts. The positioning of these grasslands is influenced by a combination of factors including rainfall patterns, climate, and the geographic features that influence them such as mountain ranges creating rain shadows and continental positioning affecting moisture availability.
