Biomes: Chapter 21, Section 4
Terms in this set (24)
A group of ecosystems with similar climates and similar organisms.
A pattern of weather within a certain area over a long period of time.
Temperature, Precipitation, Latitude, Altitude (Elevation)
The Four (4) Factors of Climate
The coldest and youngest biome. Has permafrost (frozen soil). Found at the polar regions of Earth, and Northern Alaska. Very Long winters and short mild summers. Typically characterized by having Low Temperatures and Low Precipitation, and animals like hares, caribou, polar bears and wolves.
Frozen soil layers found in the Tundra & Taiga biomes.
The largest biome, with primarily cold winters and mild summers, and many evergreen (coniferous) trees. Found in much of Canada, NW United States, and much of northern Asia (Siberia). Also known as the Boreal Forest or Coniferous forest.
Temperate Deciduous Forest
The only biome with Four (4) seasons. Contains many trees that lose their leaves. Also has fertile soil.
a broad-leaf tree that seasonally loses its leaves. It is found in the temperate forest biomes.
Grasslands / Savannas
A mostly flat and fertile biome with a lot of vegetation and many large herbivores. Found along the middle lines of latitude. Is in the Midwest United States.
The driest biome. Has poor soil due to low precipitation and low decomposition. Typically characterized by having Cacti and Mesquite plantlife, and animals such as lizards, scorpions and snakes.
Tropical Rain Forest
The wettest terrestrial biome with the most biodiversity. Gets a lot of precipitation. Has a thin layer of fertile soil. It is typically characterized by having very tall plants that create canopies with a low growing understory below.
Variety (different kinds) of life.
A covering of tall trees in the tropical rain forest, causing little sunlight to reach the ground below.
The low growing plants that grow below the canopy of tall trees within a tropical rain forest.
Consists of the Earth's Lakes, Rivers, Streams, Ponds, etc. Has many fish species, insects, and mammals. (ex: trout, bass, catfish, beaver, otter, mosquitoes)
Consists of the Earth's Oceans & Seas. Split into four zones: Estuary, Intertidal, Neritic, and Open Ocean.
The coastal areas where freshwater rivers meet the salt water oceans. Often deposits sediment to create brackish land/water zones. (Ex. Deltas, Marshlands, Barrier Islands) Contains many water birds.
The area of the marine biome where the waves break at the shore during high & low tides.
The area of the marine biome that contains the most life (biodiversity). Shallow waters allow sunlight to sustain life for plants and reefs (Coral Reefs). Has many large schools of fish.
The deep waters of the marine biome. Little sunlight can penetrate in deep water. Contains a lot strange sea life.
The main cause of the elimination of a population within a habitat.
Harmful substances that can damage or destroy habitats (Ex: Nuclear Waste, Oil Spill, Plastics in landfills, Pesticides, Fertilizers)
A catastrophic natural event that can damage or destroy a habitat (ex: Volcano, Asteroid, Floods, Drought)
The removal of trees that could result in habitat damage or destruction.
