the nile delta

Question 1

what evidence is there that this is a low energy coastline

Answer 1

• large amount of deposited sediment
• no erosional features like cliffs or wave cut platforms
• large depositional features like sand dunes

Question 2

how is a delta formed

Answer 2

• rivers entering the sea are carrying large sediment load
• a broad continental shelf margin exist at the river mouth
  overload of sediment splits into 2 channels

Question 3

how was the Damietta spit formed

Answer 3

longshore drift, along a drift aligned coastline. as waves loose energy and sediment repeatedly gets dropped

Question 4

how Burullus lagoon formed

Answer 4

water gets trapped by an onshore bar and the water that is trapped is brackish

Question 5

how did the Gammas sand dunes form

Answer 5

formed by aeolian process, with the north west movement of sediment, being pulled of onshore bars and other sources of sediment, before being caught by a object in the sand thus leading to the eventual formation of a dune

Question 6

how did the Rosetta onshore bar form

Answer 6

movement form east ward, causing sediment to push across forming the bar (drift aligned coastline)

Question 7

Sabkhas

Answer 7

formed by extreme heat leading to a salty area of water forming, due to the water drying up (hugely negative impacts on the wildlife)

Question 8

how was the Crescentic bar at Alexandria formed

Answer 8

formed due to the lack of LSD (swash aligned) and rip currents, which is pulling sediment back from the coastline., and depositing it in the form of this offshore bar

Question 9

How big is jacks nob

Answer 9

7 maybe 8
