QUIZZES // The water cycle quiz 2
Q1. The soil water budget…
…is the volume of discharge that reaches the mouth of the river
…describes changes in the soil moisture throughout the year
…describes how much water the soil can hold before becoming saturated
...is the volume of water the soil needs to keep the vegetation healthy
Q2. A water deficit occurs in the UK…
…in late summer, when there is greater evapotranspiration than precipitation
…in early spring, when there is greater precipitation than evapotranspiration
…in winter when there is much greater precipitation than evapotranspiration
…throughout the year, when the river channel is recharged by precipitation
Q3. When deforestation has occurred on a hillslope, which of the following consequences is NOT correct?
There will be increased overland flow and greater throughflow within the drainage basin, with increased soil erosion
The evapotranspiration rate will drop because there is less volume and density of vegetation
Increased interception means a greater volume of water reaching the river
Increased discharge, a flashy hydrograph and local flooding
Q4. Which of the following is an example of a porous and permeable rock type?
Clay
Sandstone
Unweathered granite
Basalt
Q5. Which of the following is an example of a porous but impermeable rock type?
Clay
Sandstone
Unweathered granite
Basalt
Q6. Which of the following is an example of a non-porous and impermeable rock type?
Clay
Sandstone
Unweathered granite
Basalt
Q7. Which of the following is NOT a true statement about interception?
There will be greater throughfall as opposed to interception once the leaves and other vegetation get wetter
Interception will remain the same throughout the year in deciduous forests
Increased wind velocity will decrease interception as water droplets become dislodged
The majority of precipitation that is intercepted will either be absorbed by the plant, or evaporated back into the atmosphere
Q8. Using figure 1 and your own knowledge, which of the following is an incorrect statement referring to the comparison between the hydrology of a tropical region and a polar region?
In the polar region there is little interception due to the low volume of vegetation, whereas in the tropical region there is a very high rate of interception throughout the year
The rate of evaporation in the polar region will vary somewhat throughout the year, whereas in the tropical region there will be much less variation in the rate of evaporation
There is a very high rate of photosynthesis in both the tropical and the polar regions
In the tropical region there is a high rate of evapotranspiration compared with the polar region, where this is very low
Q9. Which of the following terms is described in this definition: on a flood hydrograph, the recording of a decrease in the river's discharge after a storm event has passed
Bankful discharge
Peak discharge
Lag time
Falling limb
Q10. Which of the following terms is described in this definition: on a flood hydrograph, the time between the peak precipitation and the peak discharge
Bankful discharge
Peak discharge
Lag time
Falling limb
Q11. Which of the following terms is described in this definition: the maximum discharge the channel can hold. Once this is exceeded, flooding will occur.
Bankful discharge
Peak discharge
Lag time
Falling limb
Q12. Which of the following terms is described in this definition: on a flood hydrograph, when river discharge is at its greatest volume following a storm event
Bankful discharge
Peak discharge
Lag time
Falling limb
Q13. A flashy hydrograph has:
A high peak discharge, long lag time, gentle rising and falling limbs
A steady but no peak discharge, long lag time, steep rising and falling limbs
A low peak discharge, short lag time, steep rising and falling limbs
A high peak discharge, short lag time, steep rising and falling limbs
Q14. What is baseflow?
The discharge rate of the river near the mouth, before it flows into the sea
The rate at which the river discharges after a dry period at the lowest level of the year
The normal day-to-day discharge of the river from groundwater and throughflow seeping into the river channel
When river discharge is at its greatest volume following a storm event
Q15. A simple river regime means that:
There is one major period of peak river discharge throughout the year
The government has afforded some basic protections to the river ecosystem
There is only one source to the river, i.e. there are no tributaries
There are several periods of discharge extremes every year
