The primary distinction between a prairie and a savanna is the climate. Savannas, or tropical grasslands, cover almost half of the African continent and prefer warm or hot climates. Prairies, or temperate grasslands, prefer temperatures that vary from summer to winter. Prairies need less rainfall than savannas.Continue Reading
Prairies and savannas are both grasslands. A grassland is a region that is dominated by plant and grass vegetation rather than forests. Grasslands proliferated after the end of the last ice age as warmer and drier climates prevailed worldwide. Savannas are distinct in their precipitation needs. For a grassland to be a savanna, the rainfall must be concentrated into six to eight months of the year. Thus, regions in which savannas are found have both a dry and a rainy season with pretty stable temperatures year round.
Wildlife on savannas include giraffes, buffalo, mice, zebras and snakes. Prairies are characterized has having hot summers and cold winters. Rainfall falls steadily year round, with the majority falling in the early summer and late fall. The amount of rainfall determines the type and level of vegetation in a prairie. Wildlife typical to prairies includes lions, wild horses, gazelles, wolves and prairie dogs.Learn more about Landforms
Four abiotic factors in the prairie ecosystem include the climate, the topography, the soil and natural disturbances. Abiotic factors are the nonliving things or conditions that affect an ecosystem as well as the organisms that live in the ecosystem.Full Answer >
Some interesting facts about the savanna biome are that these landforms exist all over the world, they have typically two seasons and the soil may not be suitable for farming. Although there are savannas in South America and Australia, the African savanna is the one that is most famous.Full Answer >
The composition of sand is dependent on the geographical area where the sand is located. Most sands are composed of small land sediment particles, minerals, rocks and organic matter that has been eroded and ground down over many years. For this reason, sand composition varies greatly.Full Answer >
A barrier island is a long, thin stretch of sand deposited parallel to the mainland. One side of a barrier island faces the ocean, while the other side faces an estuary, bay or lagoon that separates the island from the mainland. Barrier islands are popular tourist attractions and contain fragile ecosystems with distinct habitats and wildlife. Due to their location, barrier islands serve as protection from storms for the mainland.Full Answer >
