1. Temperature:
* Latitude: As you move away from the equator, temperatures generally decrease. This influences the type of vegetation that can thrive.
* Altitude: Higher altitudes mean colder temperatures, similar to the effect of latitude.
2. Precipitation:
* Rainfall: Amount of precipitation directly affects the availability of water for plants and animals.
* Seasonality: The timing of rainfall is crucial for the growth and survival of organisms.
3. Sunlight:
* Daylight hours: The length of day and night varies with latitude, influencing plant growth and animal activity patterns.
* Intensity: Sunlight intensity is highest at the equator and decreases towards the poles.
Other influencing factors:
* Topography: Mountains and valleys create microclimates with different temperatures and precipitation.
* Soil: The composition and fertility of the soil can influence the types of plants and animals that can survive in a particular area.
* Ocean currents: Warm and cold ocean currents can influence the temperature and rainfall patterns of nearby landmasses.
Examples:
* Tropical Rainforests: Located near the equator, these biomes receive high rainfall and constant warm temperatures.
* Tundra: Found in high latitudes and altitudes, tundras experience low temperatures and short growing seasons.
* Desert: Deserts are characterized by low precipitation and high temperatures, often found in areas with high evaporation rates.
It's important to note that biomes are not fixed entities and can transition gradually into one another, creating ecotones, areas of overlap between biomes. Furthermore, human activities can also influence the distribution and characteristics of biomes through deforestation, pollution, and climate change.
