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 to 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, a long lag time, gentle rising and falling limbs

A steady but no peak discharge, a long lag time, steep rising and falling limbs

A low peak discharge, a short lag time, steep rising and falling limbs

A high peak discharge, a 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 relating to seasonal variations in precipitation

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
