Enquiry question: How are coastal processes shaping the shingle ridge at Porlock Bay?

Select the correct hypotheses:

• We expect sediment size to be smaller in the east than the west

• We expect sediment size to be smaller in the west than the east

• We expect sediment size to be rounder in the west than the east

• We expect sediment size to be rounder in the east than the west

Enquiry question: How are coastal processes shaping the shingle ridge at Porlock Bay?

Select the correct hypothesis:

• We expect the beach to be wider and higher in the east

• We expect the beach to be wider and higher in the west

• We expect there to be no difference in the width and height of the beach at either end of Porlock Bay

Hypothesis - beach profile

If we expect sediment size to be smaller in the east due to attrition, we would therefore expect the beach gradient to...

• be less steep in the east

• be steeper in the east

• be very similar at either end of the bay
