Where is the source of the River Wye?

• Cross Fell in the Pennines

• Plynlimon in the Cambrian Mountains

• Penshurt in the Grampians

• Teign Head in Dartmoor

Where is the mouth of the River Wye?

• Thames estuary

• Humber estuary

• Firth of Forth

• Severn estuary

What direction is the River Wye flowing from Hereford to the mouth of the river?

• north

• east

• south

• west

Which of the following relates to rainfall, in Plynlimon, the source of the River Wye?

• November has the most rain, with an average of 247mm

• December has the most rain, with an average of 327mm

• January has the most rain, with an average of 157mm

• February has the most rain, with an average of 167mm

Which of the following relates to temperature, in Plynlimon, the source of the River Wye?

• May is the hottest month, with an average temperature of 20.9ᵒC

• June is the hottest month, with an average temperature of 5ᵒC

• July is the hottest month, with an average temperature of 14.1ᵒC

• August is the hottest month, with an average temperature of 10.3ᵒC

How does human activity affect geomorphic processes in the River Wye? (Select 2)

• a weir on the River Monnow, a tributary of the River Wye, was removed which led to increased rates of erosion

• the high rainfall has led to increased rates of abrasion

• the cold temperatures in January can lead to freeze-thaw weathering

• in the upper course of the River Wye trees have been planted which have reduced mass movement

How has geology influenced geomorphic processes in the River Wye?

• at Plynlimon the impermeable, hard rock ie shales and gritstone have increased the rate of surface runoff. Hydraulic action has vertically eroded these v -shaped valleys.

• at Plynlimon the soft rock has led to slumping (mass movement)

• at Plynlimon the lateral erosion has led to wide meanders

How has geology influenced geomorphic processes in the River Wye?

• in the lower course of the River Wye the mudstone to the south of Hereford has eroded vertically to create steep v-shaped valleys

• in the lower course of the River Wye the mudstone to the south of Hereford has eroded through lateral erosion to create wide meanders

• in the lower course of the River Wye the mudstone to the south of Hereford creates waterfalls

• in the lower course of the River Wye the mudstone to the south of Hereford has caused the river to flow quickly

How has climate influenced geomorphic processes in the River Wye? (Select 2)

• January has the most rain, with an average of 157mm. This increases rates of erosion through hydraulic action and abrasion

• the lack of rainfall in August can increase the rate of erosion through attrition

• February is the coldest month. When the temperatures are below 0ᵒC freeze-thaw weathering increases erosion through abrasion

• the hot temperatures in July can lead to more relief rainfall

Name the river landform you can see in the photo of the River Wye

• v-shaped valley

• u-shaped valley

• meander

• ox-bow lake
