Ecological Variation and Earth's Biomes

These flashcards cover key concepts related to ecological variation and biomes, as derived from the lecture notes.

Ecological Variation

Differences in climate, soil, vegetation, and animals across different biomes.

Biomes

Large areas characterized by specific climates, plants, and animals.

Coriolis Effect

The deflection of air currents caused by the Earth's rotation.

Solar Radiation

The energy emitted by the sun, which is unevenly distributed across the Earth's surface.

Precipitation

Any form of water that falls from clouds, including rain, snow, sleet, and hail.

Soil Profile

A vertical section of soil that showcases different soil horizons.

Soil Horizons

Layers of soil that differ in composition, texture, and color; includes O, A, E, B, and C horizons.

Desert Biome

A biome characterized by low rainfall, typically occurring at 30° N and S latitude.

Jet Streams

High-altitude winds that flow from west to east, influencing climate and weather patterns.

Rain Shadow Effect

The dry area on the leeward side of a mountain range where moist air loses its moisture.

Nutrient Recycling

The process by which nutrients are reused and returned to the ecosystem, particularly in tropical rainforests.

Tropical Rainforest

A biome found near the equator characterized by high rainfall and biodiversity.

Topography

The arrangement of the natural and artificial physical features of an area, which affects climate.

Soil Composition

The mixture of organic and inorganic materials that make up soil, affecting its properties.

Atmospheric Circulation

The large-scale movement of air masses that distributes heat and moisture around the globe.

Terrestrial Biomes

Land-based biomes defined by their climates, soils, and the life forms they support.
