Water and Carbon Cycles Worksheet

Which of the following is considered an input in the water cycle of a drainage basin?

• Precipitation

• Burning

• Production of glucose

• Absorption

What is the main process responsible for the production of glucose in the carbon cycle within woodlands?

• Photosynthesis

• Evapotranspiration

• Infiltration

• Sublimation

Which of the following best describes a positive feedback loop in the context of the water and carbon cycles?

• A cycle of events that amplifies change and moves a system away from equilibrium

• A process that neutralizes change and moves a system towards equilibrium

• The transfer of water from the surface into the soil

• The storage of water in lakes and rivers

What is the main effect of increased atmospheric CO₂ on the carbon cycle?

• Promotes plant growth and higher rates of photosynthesis

• Reduces infiltration and interception

• Increases evaporation from oceans

• Causes more melting of ice

Which of the following is NOT a major store in the water cycle?

• Lithosphere

• Hydrosphere

• Troposphere

• Cryosphere

What is the process called when water moves from the surface into the soil?

• Infiltration

• Evapotranspiration

• Sublimation

• Condensation

Which of the following best describes the term "dynamic equilibrium" in the context of the water and carbon cycles?

• A state where there has been no significant human/natural impacts so the system has had time to adjust to change

• The process of water soaking into rocks

• The transfer of energy through latent heat

• The production of glucose through photosynthesis

What is the main function of stemflow in the drainage basin?

• Precipitation drips down stems of plants to surface

• Water runs off large surface areas

• Water soaks into the soil

• Water evaporates from plant leaves

Which human activity is most likely to reduce interception and infiltration in the hillslope cycle?

• Deforestation

• Urbanisation

• Farming

• Seasonal storms

What is the effect of impermeable rocks on water transfer in a drainage basin?

• Rapid overland flow

• Slow transfer by groundwater flow

• Increased interception

• Increased evaporation
