River Tees - Source to Mouth

What is a notable characteristic of the UK's physical landscape?

• It is predominantly flat and uniform.

• It changes very quickly in appearance from one place to the next.

• It consists mainly of vast, unchanging deserts.

• It has a consistent tropical climate across all regions.

Where does the River Tees originate?

• The Scottish Highlands

• The Welsh Valleys

• The Moorlands of Cumbria

• The White Cliffs of Dover

Which of the following accurately describes the Moorlands environment where the River Tees originates?

• It is a dry, arid region with sparse vegetation.

• It is characterized by high altitude, low temperatures, and bogs that soak up water.

• It is a fertile plain with abundant sunshine and moderate rainfall.

• It features dramatic rocky mountainsides with tumbling rivers.

What are the three main types of sediment carried by a river?

• Clay, silt, and sand

• Solute load, suspended load, and bedload

• Organic matter, minerals, and pollutants

• Gravel, pebbles, and boulders

What is characteristic of the river's bedload and erosive energy in its upper course, close to the source?

• The bedload consists of sharp, angular rocks, and erosive energy is low.

• The bedload is smooth and rounded, and erosive energy is high.

• The bedload is primarily fine sediment, and erosive energy is moderate.

• The bedload is large and angular, and erosive energy is minimal.

What physical characteristic do the pieces of bedload in the river's upper course acquire due to the ongoing erosion?

• They become larger and more angular.

• They develop sharp edges and irregular shapes.

• They become smooth and rounded.

• They break down into fine sand and silt.

Which combination of factors contributes to the most powerful erosion in the upper sections of a river, leading to the formation of steep V-shaped valleys?

• Low gradient, low water volume, and fine bedload.

• High gradient, high water volume, and significant bedload.

• Moderate gradient, low water volume, and minimal bedload.

• Flat terrain, high water volume, and coarse bedload.

What geological process explains how a waterfall, like High Force, forms and retreats upstream, eventually creating a gorge?

• The river erodes the hard rock layer on top, causing it to collapse.

• The river erodes the softer rock layer beneath the hard rock, creating an overhang that eventually collapses.

• Tectonic plate movement causes the riverbed to uplift, forming a waterfall.

• Sediment deposition builds up the riverbed, leading to a sudden drop.

How are oxbow lakes formed in a river's lower section?

• Through continuous erosion on the inside bend of a meander.

• By deposition of sediment on the outside bend, blocking the flow.

• When a river meander becomes so pronounced that its neck is cut through, creating a new, straighter channel.

• As a result of human intervention to straighten the river course.
