Which feature is most characteristic of the tundra biome?
High tree diversity
Warm temperatures year-round
Permafrost layer in the soil
Heavy rainfall
Tundra is defined by a layer of permanently frozen soil called permafrost. It experiences low temperatures and minimal precipitation, preventing tree growth. The permafrost layer controls drainage and root penetration, shaping the unique tundra landscape. Britannica.
Which type of vegetation dominates the tundra?
Dense deciduous forests
Grasses and wildflowers
Mosses and lichens
Cacti and succulents
In the tundra, low temperatures and short growing seasons limit plant diversity. Mosses and lichens are well adapted to cold, can photosynthesize at low temperatures, and survive in thin soils. These organisms form the foundation of tundra ecosystems by providing nutrients and stabilizing soil. National Geographic.
The tundra biome is primarily found at which latitudes?
Near the equator
High northern and southern latitudes
Mid-latitudes
Tropical regions
Tundra occurs near the poles, above the Arctic Circle in the north and in Antarctica’s fringe. These high-latitude regions experience extreme cold, limited precipitation, and permafrost. Vegetation is sparse due to harsh conditions and short summers. Britannica.
During which season does the Arctic tundra experience continuous daylight?
Summer
Winter
Spring
Autumn
The Arctic experiences polar day, or the "midnight sun," in summer months when the sun remains above the horizon for 24 hours. This continuous daylight supports a brief, intense growth period for tundra plants. In contrast, winter brings polar night with continuous darkness. National Geographic.
The Arctic tundra differs from alpine tundra in that the Arctic tundra is located:
At high elevations worldwide
In high-latitude regions
Only on mountain tops
In tropical highlands
Alpine tundra occurs at high altitudes above the tree line on mountains, regardless of latitude. Arctic tundra is found in high-latitude areas near the poles and is defined by permafrost. Both biomes have similar vegetation but differ by their geographic settings. National Geographic.
Which of the following animals is NOT native to the tundra?
Musk ox
Kangaroo
Polar bear
Arctic fox
Kangaroos are native to Australia’s grassland and forest biomes, not cold, high-latitude tundra. Polar bears, Arctic foxes, and musk oxen have specialized adaptations like thick fur and fat layers for Arctic conditions. These mammals are integral to tundra ecosystems. Britannica.
What adaptation helps many tundra plants conserve heat and resist wind damage?
Growing as tall trees
Developing thick bark
Adopting low-growing, cushion-like forms
Producing large leaves
Tundra plants often grow in low, cushion-like mats close to the ground, which reduces exposure to cold winds and conserves heat. This growth form also traps moisture and can increase soil temperatures near the plant base. Such adaptations are crucial for survival in harsh tundra climates. Britannica.
What soil order is most commonly associated with the tundra biome?
Ultisols
Mollisols
Gelisols
Vertisols
Gelisols are soils that contain permafrost within two meters of the surface. They are typical in tundra regions where permanently frozen ground influences water movement and soil development. The frozen layer restricts drainage and root growth. USDA NRCS.
In the tundra biome, the “active layer” refers to the soil that:
Remains frozen year-round
Thaws seasonally above the permafrost
Is too rocky for plants
Is permanently waterlogged
The active layer is the topsoil that thaws during the short summer months, allowing plant roots to grow and microbes to become active. Beneath it lies the permafrost, which remains frozen year-round. The thickness of the active layer fluctuates with temperature and precipitation. USGS.
Which greenhouse gas is released in significant amounts when tundra permafrost thaws?
Oxygen
Nitrogen
Methane
Hydrogen
Thawing permafrost releases stored organic matter, which decomposes and emits methane and carbon dioxide. Methane is particularly potent, having a stronger near-term warming effect than CO?. This feedback loop accelerates climate change in polar regions. NOAA.
The average annual precipitation in most tundra regions typically falls within which range?
200–600 mm
1000–1500 mm
1500–2000 mm
50–100 mm
Tundra climates are classified as cold deserts or semi-deserts, with low precipitation similar to that of drylands. Most tundra zones receive between 200 and 600 millimeters of moisture annually, mainly as snow. Limited precipitation and low evaporation rates shape the ecosystem. Britannica.
What seasonal coat adaptation does the Arctic fox employ for survival?
Growing spines
Expanding ears
Changing fur color
Shedding all fur
Arctic foxes develop thick white fur in winter for camouflage against snow and to trap heat, then molt to a brown or gray coat in summer to blend with rocky tundra soil. This seasonal change aids hunting and predator avoidance. Fur density also varies, providing insulation in extreme cold. National Geographic.
In tundra landscapes, what is a “palsa”?
A type of glacier
A peat mound with an ice core
A seasonal river channel
A wind-sculpted dune
Palsas are low, often circular mounds comprised of peat and ice that form when frozen groundwater pushes soil upward. They are common in discontinuous permafrost zones and indicate local variations in soil and moisture. Palsas can collapse when ice cores melt. ScienceDirect.
Which large herbivore migrates seasonally across tundra landscapes?
Moose
Caribou
Bison
Beaver
Caribou (known as reindeer in Eurasia) undertake extensive migrations from wintering grounds to summer calving areas, sometimes traveling thousands of kilometers. These movements are driven by forage availability and predator avoidance. Caribou herds are critical to both ecosystem dynamics and indigenous cultures. Britannica.
What term describes the irregular surface collapse in permafrost regions due to thawing ice-rich ground?
Thermokarst
Cryoperturbation
Solifluction
Eutrophication
Thermokarst refers to landforms that develop when ice-rich permafrost thaws, causing the ground to subside and form depressions or sinkholes. These features create ponds and uneven terrain in thawing regions. Thermokarst processes contribute to carbon release and alter hydrology. National Geographic.
Which type of lake is commonly formed by ground subsidence in tundra regions?
Oxbow lake
Thermokarst lake
Rift lake
Cirque lake
Thermokarst lakes develop when thawing permafrost creates depressions that fill with meltwater. They are characteristic of tundra environments and can expand as permafrost continues to thaw. These lakes influence local ecosystems and release greenhouse gases. USGS.
Approximately how much organic carbon is estimated to be stored in permafrost soils worldwide?
500 gigatons
1600 gigatons
50 gigatons
2500 gigatons
Permafrost soils contain roughly 1600 gigatons of organic carbon, nearly twice the amount in the atmosphere. When thawed, microbes decompose this material, releasing carbon dioxide and methane. This vast carbon pool makes permafrost a critical factor in global climate feedbacks. Nature.
Which biome borders the tundra to the south in northern regions?
Temperate rainforest
Boreal forest (taiga)
Savannah
Tropical rainforest
South of the tundra in the Northern Hemisphere lies the boreal forest or taiga biome, dominated by coniferous trees like spruce and fir. The transition zone, called the tree line, marks where harsh tundra conditions prevent tree growth. This gradient is driven by temperature and soil changes. Britannica.
Caribou migrations in the tundra can span approximately how many kilometers per year?
200 km
1000 km
5000 km
10000 km
Some caribou herds journey around 5,000 kilometers annually between wintering grounds and calving areas. Such long-distance migrations are among the longest for land mammals and reflect adaptations to seasonal forage patterns. Tracking these movements helps in conservation planning. National Geographic.
Which type of microbe thrives in cold tundra soils and contributes to nutrient cycling?
Thermophilic bacteria
Halophilic archaea
Psychrophilic bacteria
Mesophilic fungi
Psychrophilic (cold-loving) bacteria can grow at temperatures near freezing and play key roles in decomposing organic matter in tundra soils. They release nutrients that support the limited plant communities. Their activity accelerates during the thaw season in the active layer. NIH.
What does the term “cryoturbation” describe in permafrost soils?
Soil mixing due to freeze-thaw cycles
Expansion of ice lenses
Formation of glacial valleys
Acidification of tundra soils
Cryoturbation is the disturbance and mixing of soil layers caused by repeated freeze-thaw cycles in cold environments. This process can bring buried organic material to the surface and affects soil structure and nutrient distribution. Cryoturbation shapes the distinctive patterned ground seen in tundra areas. Britannica.
What are cushion plants in the tundra?
Plants forming low, dense mats to reduce heat loss
Tall grasses that cushion soil erosion
Aquatic plants in tundra ponds
Epiphytic mosses on trees
Cushion plants grow in compact, domed shapes that minimize wind exposure and retain heat and moisture. This growth form enables survival in cold, windy tundra environments with thin soils. Cushion species like Silene acaulis are common in alpine and arctic tundra zones. Britannica.
Which stable isotope ratio is commonly analyzed in tundra permafrost studies to reconstruct past vegetation and climate?
Oxygen-18 to Oxygen-16
Carbon-13 to Carbon-12
Nitrogen-15 to Nitrogen-14
Hydrogen-2 to Hydrogen-1
The ratio of carbon-13 to carbon-12 (?13C) in organic matter provides insights into past plant communities and photosynthetic pathways. In permafrost cores, ?13C values help reconstruct changes in vegetation and climatic conditions over millennia. This isotope analysis is a key tool in paleoclimate research. ScienceDirect.
In Siberian tundra studies, what does the term “yedoma” refer to?
A seasonal thaw event
Ancient, ice-rich loess deposits
A type of tundra lichen
Coastal permafrost erosion
Yedoma are Pleistocene-age silty sediments rich in organic carbon and ice, common in Siberia and Alaska. They formed under cold, dry glacial conditions and, when thawed, can release large amounts of greenhouse gases. Yedoma deposits store vast carbon reserves. Nature Geoscience.
How does the recent expansion of shrub species in tundra regions primarily affect permafrost?
Increases snow insulation, leading to deeper thaw
Reflects more solar radiation, cooling the ground
Pumps heat to the surface, causing freeze
Prevents soil moisture retention
Taller shrubs trap more snow, which insulates the soil and raises winter ground temperatures, promoting deeper seasonal thaw of the active layer. This process can accelerate permafrost degradation and alter ecosystem dynamics. Shrub expansion is a key climate feedback in tundra regions. Nature Climate Change.
