Y11 COASTAL FIELDWORK 1

Give two advantages of random sampling.

• It avoids bias

• It allows a wide range of data to be analysed

• It reduces a large sample size

• comparisons can be easily made

Which equipment would you use to measure beach gradient?

• ranging pole, orange, measuring tape, stop watch

• ranging pole, clinometer, measuring tape

• quadrant, 1 metre ruler, stop watch

• clipboard, pencil, measuring tape

You would use a BLANK to measure the angle of a beach.

• compass

• measuring tape

• calipers

• clinometer

You would use a BLANK to measure the height of a beach.

• orange

• clinometer

• ranging pole

• measuring tape

You would use a BLANK to measure the width of a beach.

• measuring tape

• ranging pole

• stop watch

• clinometer

What is a disadvantage of collecting data when measuring the gradient of a beach? (GIVE TWO MOST APPROPRIATE ANSWERS)

• An inaccurate angle recorded can give a wrong profile of a beach

• The beach might be steep

• It is difficult to read the angle on a clinometer

• There may be a long width, meaning there is a lot to measure

What piece of equipment is being referred to "The reference point is difficult to line up, resulting in an inaccurate readking taken from the clinometer."

• measuring tape

• Callipers

• 1 metre rule stick

• ranging pole

Would you expect the gradient of a beach to steeper at the nearshore (near the sea) or backshore (near the cliff)

• nearshore

• backshore

• both

You are measuring the process of longshore drift on a stretch of coastline. What would you notice about the materials as you move along the beach.

• pebbles become rounded and smaller

• pebbles become more angular

• there are less pebbles

• i like sand castles

You are measuring the process of longshore drift on a stretch of coastline. What would you notice about beach

• the beach becomes steeper

• the beach disappears

• the beach becomes wider (depth!)

• which ways the beach man??
