2. Backwash
Backwash is the movement of water after the waves swash on the coast

3. beach
Beach is the landform along the coast ,often the beach has rock, sand, gravel, shingle, or pebbles.

4. Cave ,arch ,stack ,stump
The waves erode the headland, the cracks grow larger and form a cave.
The cave still eroded and form an arch.
After many years the arch will collapse and transforms into a stack.
In the end the stack will erode to a stump

6. Constructive waves
They are created in calm weather and are less powerful than destructive waves . They break on the shore and deposit material, building up beaches .They have a swash that is stronger than the backwash

7. Deposition
Deposition is the geological process in which sediments, soil and rocks are added to a landform or land mass. It is deposited, building up layers of sediment.

8. Destructive waves
They occur when wave energy is high and the wave has travelled over a long fetch . They tend to erode the coast . They have a stronger backwash than swash.

9. Erosion Erosion is the act in which earth is worn away.
Hydraulic action: is erosion that occurs when the motion of water against a rock surface (cracks) helps to break it up.
Abrasion: Bits of rock and sand in waves grind down cliff surfaces like sandpaper.
Solution: Acids in sea water dissolve some types of rock such as chalk or limestone.
Attrition: Waves smash rocks and pebbles on the shore into each other, and they break and become into smaller bits.

11. Head lands/bays
Headlands and bays are often found on the same coastline. A bay is surrounded by the headland. A headland is surrounded by water in thee sides.

12. Fetch The Fetch is the length of water over which the wind has blown.

13. Longshore drift
Longshore drift consists of the transportation of sand and shingle along a coast which dependent on prevailing wind direction, swash and backwash

14. Shingle Shingles are pebbles or small to medium size cobbles.

15. Salt marsh
A salt marsh,, is a coastal ecosystem in the upper coastal intertidal zone between land and open salt water or brackish water that is regularly flooded by the tides. It is dominated by dense stands of salt-tolerant plants such as herbs, grasses, or low shrubs. Also in the salt marsh they are living different species like birds (flamingo) and snakes.

17. Sand spit
A sand spit is a beach landform found off coasts. It develops in places where headlands erode by the process of longshore drift.

18. Swash
The swash is layer of water that washes up on the beach after an incoming wave has broken.

19. Tidal range
The tidal range is the difference between the high tide and the low tide.

21. Tide (high tide, low tide)
Tides are the rise and fall of sea levels as the moon travels around the earth.
High tide is the highest level of the sea in that day.
Low tide is the lowest level of the sea in that day.

22. Wave cut notch
This is like a small cave, created by the erosion of the waves.

23. Wave cut platform
A wave-cut platform is a flat area often found at the base of a sea cliff or bay, or sea that was created the erosion of waves.
