Distinctive Landscapes C.S.

Question 1

List the Dorset coast’s landforms created by geomorphic processes.

Answer 1

• Durdle Door is an arch in a limestone headland.
• The Foreland lies between Swanage and Studland bay.
• Old Harry (stack) and Old Harry’s wife (stump) - off the end of The Foreland - are made from chalk.

Question 2

How do climate and geology influence geomorphic processes on the Dorset coast?

Answer 2

• Climate change provides destructive waves.
• Increasing sea levels mean more erosion.
• Freeze-thaw weathering depends on temperatures.
• Discordant coastline means differential erosion.

Question 3

How has the south Dorset coast been managed?

Answer 3

• Rock armour was placed at cliff bases in 1980.
• Sea wall and groynes placed in late 18th century, again in 1930s and 1960s.
• From Nov 2005 to June 2006, 90,000m3 of sand replenished the beach at a cost of £2.2 million.

Question 4

List the River Clyde’s landforms created by geomorphic processes.

Answer 4

• The Falls of Clyde are 4 waterfalls near Lanark.
• Crawford has 300-500m high interlocking spurs.
• There are meanders between Motherwell and Glasgow, with an oxbow lake forming near Uddingston.
• Glasgow is built on ground ~5m above sea level.

Question 5

How do climate and geology influence geomorphic processes along the River Clyde?

Answer 5

• Hotter temperatures can speed up formation of meander scars.
• Climate can increase flood events.
• Glasgow is built on metamorphic and igneous rock.
• Larger rocks are deposited closer to the channel during flooding.

Question 6

How has the River Clyde been managed?

Answer 6

• During floods, water is redirected to underground storage that can hold 2.59 billion litres.
• This reduces discharge reaching Glasgow by 50%.
• Flood warnings and SUDs (Sustainable Urban Drainage Systems) protect ~12,000 people across 4 areas.
