1.2 Flashcards
Biome
An area that shares a combination of average yearly temperature and precipitation
Factors influencing climate
topographic features (terrains), altitude, distance from water bodies
Significance of nutrient availability
Differences in nutrients affects what plants grow and how many
How do biomes shift
As the earth’s temperature fluctuates, biomes can move to geographic areas with similar climates.
Tundra features
coldest biome on earth, cold winters, little rain, relies on snow for moisture, trees cannot grow but rather mosses and low-growing plants, home to permafrost and arctic animals
Boreal forrest / Taiga
coniferous forest biome found in high lattitudes of Northern hemisphere, long cold winters, cool summers, second-coldest
Temperate Rainforest
moderate temperatures, high precipitation, most species diversity, unique conditions with proximity to oceans, low soil nutrients due to rainfall
Woodland / Shrubland
Southern Cali, Austrailia, South America, 12-month growing season, hot dry summers, rainy winters, droughts & wildfires.
Tropical Rainforest
near equator, little seasonal temperature variation, hot and humid, high precipitation, low soil nutrients, highest biodiversity
Savanna
dry hot seasons, few green trees or plants, rich soil composition, large plants not found due to dry climate, high biodiversity.
Subtropical Desert
very hot and very dry, almost no nutrients, very little biodiversity, cacti & succulents, low precipitation
