Explanation / Answer

1. The statement is false because barnacles and mussels have a symbiotic relationship within them.After attaching themselves to the back of a mussel, barnacles benefit from the relationship in a number of ways. Not only is there an increased surface area on which to settle, which keeps down competition, but sitting near the mussel's siphons - the intake and outflow pipes through which it draws water to filter out microscopic morsels of food - the barnacles also benefit from the delivery of food carried along on the micro-currents.

2. Biogenous sediments are mainly comprises of siliceous and calcareous ooze

Cosmogenous sediments are carried to earth on meteorite or asteroid, so meteorite fragments are cosmogenic.

Sea walls are hard stabilization structures built near the beach parallel to shore to protect the coast from the force of waves.

Lithogenous sediments includes sediments derived from the land.for ex, sea stock.

Wave erosion (refraction and diffraction) forms Tombolo.

Turbidity current deposits-Graded beds reflect transport by density or turbidity currents.

Wave reflection - wedge at NewPort is formed by wave reflection

Deposition by long shore transport- Longshore transport has an effect on the size grains. For example, quartz and feldspar sand grains.

3.A coral reef is made of thin layers ofcalcium carbonate. Coral polyps form a living mat over a calcium carbonate skeleton. So the statement is true.
