Wave type: ... waves are low in height, have a long wavelength and a low frequency, breaking 6-8 per minute. They have strong swash and weak backwash and therefore deposisit sediment

Card 7
Front
Wave type: ... waves have a greater height, short wavelengths and high frequency, breaking 12-14 times per minute. These waves have a stronger backwash than swash and therfore remove sediment from the beach by the process of erosion

Card 8
Front
Breaking waves: ... waves are steep waves breaking onto gently sloping beachers, water spills gently forward as the wave breaks
Back
Card 9
Front
Breaking Waves: ... waves are moderately steep waves breaking onto steep beaches, water plunges vertically downwards as the crest curls over
Back
Card 10
Front
Breaking Waves: ... waves are low-angle waves breaking onto steep beaches, the wave slides forward and may not actually break

... are the rise and fall of the sea surfacewhich are influenced by gravitational pull of the sun and moon
Back
Card 12
Front
Tides: A ... is when the sun, moon and earth are alligned. The pull is at its strongest so there is a high tidal range with high,high tides and low,low tides. These tides occur twice a month when there is a full moon
Back
Card 13
Front
Tides: A ... occurs when the sun and moon are at right angles to the earth. A smaller tidal range is created because the sun cancels out the pull of the moon

... describes physical and chemical composition of rocks
Back
Card 15
Front
Structure: These coastlines occur when the rock structure is parallel to the coast and coves are created because the waves erode the same type of rock along the coastline
