Waves and Shores

I transport material along a beach. What am I.

• Longshore Drift
• Longshape Drift
• Longnose Drift
• Longway drift

I am the forward motion of waves

• Backwash
• Swash

Waves are created by wind 

• True 
• False 

Abnormal rise in seawater level as the result of storms. Usually measured as the height of water above the normal predicted tide.

• storm surge

• swash

• backwash

• breakwater

Why are sea walls built along our coast?

• so our ships have a safe passage along our coastline

• to provide a safe swimming area for people visiting the coastline

• to reduce erosion

• to reduce deposition

What is hard stabilization?

• Something that is difficult to achieve

• Something that works with nature by using natural materials

• Something that involves building structures

What is Erosion?

• When waves lose energy and leave sediments / sand along a coast.
• The wearing away of land, removal of beach rocks/sand by water or wind.
• An area of land that smells different to other places.
• An area that has a lot of wind.
  

What are destructive waves?

• Waves that are tall and frequent, crashing into shoreline, digging out chunks.
• Long and low waves, beginning far out in the sea, with a smooth gentle landing.
• The circular movement caused by wind and gravity fighting.
• When people wave their hand to aggresively destroy things.

I am the type of erosion where sediment scrapes against the headland. What am I?

• Attrition
• Hydraulic action
• Solution
• Abrasion

I happen when the waves don't have enough energy to carry sediment

• Deposition
• Erosion
• Swash
• Backwash
