Year 9 Geography Fieldwork and Biomes Flashcards

Vocabulary flashcards covering biocultural values of Australian flora, environmental indicators from fieldwork (pH and soil moisture), and key features of biomes.

Biocultural Values

The biological and cultural significance that specific flora, fauna, or environments hold for a human community or First Nations people.

Banksia

A native plant whose sweet nectar-covered flower spikes were sucked for taste, soaked in water by the Noongar people to treat coughs and sore throats, fermented into 'bool', and harvested for edible insect larvae.

Acacia Longifolia (Sydney Golden Wattle)

A native Australian plant used as a source of starch for meals like damper before wheat was introduced, planted to slow soil erosion, and used to make yellow and green dyes.

Gum Trees (Eucalyptus)

Native trees whose leaves and oils were used for traditional medicine to treat colds and cuts, bark for shelters and water containers, and wood for tools, firewood, and weapons like shields, spears, and boomerangs.

Bottlebrush (Callistemon)

A plant valued by First Nations people for its sweet red flower nectar used to make drinks, and whose crushed leaves provided medicinal oils for healing skin infections.

Lomandra Longifolia (Australian Basket Grass)

A native plant with strong leaves woven into baskets, rope, and fishing traps, edible leaf bases chewed for energy, and seeds processed into flour.

Ground Level Image

A photograph taken from eye level on the ground that provides detailed information about specific physical features like plants, soil, and vegetation.

Oblique Aerial Image

An image captured from above at an angle using a drone or aircraft, useful for showing large geographical areas and landscape patterns.

pH Scale

A scale ranging from 0 to 14 measuring hydrogen potential, where values below 7 are acidic, 7 is neutral, and values above 7 are alkaline or basic.

Recommended Safe Water pH

The natural safe range for drinking water, which is between 6.5 and 8.5 pH (or between 5.5 and 7.5 pH for irrigation water).

Healthy Soil pH Range

A soil pH level between 6 and 7 (slightly acidic), which allows plants to absorb nutrients most effectively.

Soil Moisture

The volume of water stored in soil, determined by rainfall, slope drainage, soil texture, and organic matter, which directly affects plant root respiration and nutrient uptake.

Desert Biome

A biome characterized by receiving less than 25 centimeters of annual rainfall, extreme temperature shifts between hot days and freezing nights, and dry, sandy or rocky soil.

Tundra Biome

A treeless biome characterized by permafrost, freezing high winds, severe water scarcity, and extreme light variation between total winter darkness and 24-hour summer sun.

Permafrost

A layer of subsoil beneath the surface in tundra environments that remains completely frozen all year round.

Temperate Forest Biome

A biome featuring four distinct seasons, warm humid summers, winter snow, and canopy trees like oaks and maples that shed colorful leaves in autumn.
