Biomes and climate zones flashcards

What is a biome?

A large ecological area with distinct plant and animal groups adapted to its environment.

Desert characteristics

Low rainfall, extreme temperatures, sparse vegetation, often sandy or rocky.

True or false: Biomes are only found in tropical regions.

False, because biomes exist across all climate zones.

Difference between tundra and taiga

Tundra has permafrost and low vegetation; taiga is a coniferous forest with more trees.

Fill the blank: The ______ is the largest biome on Earth.

ocean.

Temperate forest features

Four seasons, varied precipitation, deciduous trees like oaks and maples.

Which biome has the highest biodiversity?

Tropical rainforest, due to its warm climate and abundant rainfall.

Savanna climate

Warm temperatures, seasonal rainfall, and grasses with scattered trees.

What defines a climate zone?

Region with specific temperature and precipitation patterns over time.

True or false: Grasslands are wetter than deserts.

True, because grasslands receive more rainfall than deserts.

Major factors affecting climate

Latitude, altitude, ocean currents, and wind patterns.

Polar biome characteristics

Extremely cold temperatures, ice-covered regions, and minimal vegetation.

Characteristics of chaparral

Hot, dry summers, mild, wet winters, and drought-resistant plants.

What is permafrost?

A permanently frozen layer of soil found in polar regions.

Rainforest layers

Emergent, canopy, understory, and forest floor, each hosting different organisms.

Difference between climate and weather

Climate is long-term patterns; weather is short-term atmospheric conditions.

What is a microclimate?

A small area with a different climate than the surrounding region.

Marine biome features

Saltwater ecosystems, diverse species, includes oceans, coral reefs, and estuaries.

Temperate grassland climate

Hot summers, cold winters, moderate rainfall, dominated by grasses.

Biodiversity importance

Supports ecosystem productivity, stability, and resilience.
