Notes:
On the basis of size of particles, the terrigenous deposits may be categorised into three classes—
mud, sand and gravel.
Mud refers to the finest particles which comprise the minute particles of rock forming minerals, principally quartz. Murray has classified the mud deposits into blue, green and red types, based on the colour of constituents.
Sand refers to the coarser particles, while gravel has even bigger particles.
29. Which among the following statements is not correct about the formation of corals?
