Chapter 5: Problem 8

Describe how differences in climate cause Earth to be partitioned into major biomes.

Short Answer

Expert verified

Differences in climate like temperature, precipitation, sunlight, and wind play an essential part in partitioning the Earth into major biomes. These factors determine the type of biome as they decide the plant and animal life that can sustain in that particular environment. For instance, biomes range from deserts in hot dry climates to tundras in cold climates, tropical rainforests in hot and wet climates, and even aquatic biomes based on water factors.

Step by step solution

Clarify the Concept of Biomes

Biomes are large regions of the Earth, identified by the distinct climatic conditions and the communities of plants and animals living within them. There are several major types of biomes, including deserts, forests, grasslands, tundra, and aquatic environments.

Discuss Different Climate Factors

Climate plays a significant role in determining the type of biome that can exist in a particular place. Factors such as temperature, precipitation (rain, snow), sunlight, and wind influence the types of species that can survive and the characteristics of the ecosystems within the biomes. For example, a biome with hot and wet climate can support tropical rainforests, while an extremely cold climate would host a tundra biome.

Explain How Climate Differences Partition Earth into Biomes

Temperature and precipitation are essential climate factors that determine the types of plants that can grow in an area, which in turn, defines the type of biome. warmer and wetter climates near the equator support lush, diverse populations of plants and are considered tropical rainforests. Moving further from the equator, temperatures decrease and conditions become suitable for deciduous and coniferous forests. In places where temperatures are cold and precipitation is scarce, like the arctic regions, tundra biomes exist. Dry and hot climates, such as those experienced in parts of Africa and Australia, support desert biomes.

Highlight the Role of Aquatic Biomes

Not all biomes are terrestrial; aquatic biomes, including freshwater and marine biomes, also cover a large portion of the Earth. The type and distribution of life in aquatic biomes is determined by factors such as sunlight, temperature, depth, and salt concentration. For example, aquatic life varies significantly between freshwater bodies like lakes and ponds, brackish water in estuaries, and in the different zones of the ocean.
