• 0.8m/yr

• 1.0m/yr

• 10m/yr

What is the tidal range of the N Yorks coastline like?

• Micro-tidal

• Meso-tidal

• Macro-tidal

What is the direction the dominant waves come from on the N Yorks coastline?

• South West

• North

• East

• South

How large is the fetch into the N Yorks coastline?

• 500km

• 1000km

• 1500km

• 2000km

Why are cliffs steep in the northern section of the N Yorks coastline?

• Horziontally bedded

• High amounts of weathering

• Weaker lithology

Where is the major shore platform on the N Yorks coastline?

• Robin Hood's Bay

• Flamborough Head

• Saltburn

• Filey Bay

Where is wave energy focussed on the N Yorks coastline?

• Spurn Head

• The headlands

• The bays

• Saltburn

Why are spits and drift-aligned features rare in the northern section of the N Yorks coastline?

• There is a lack of sediment

• High wave energy transports sediment quickly

• Low wave energy reduces erosion
