Answer 2

A.  Inland drainage is that drainage in which rivers do not reach an ocean or sea but empty their waters in a lake or an inland sea.

Main Characteristics of Inland Drainage:

i. In inland drainage streams join lakes or inland seas.

ii. They are fed by rainy water.

iii. During rains they experience flash floods.

iv. During dry season they get dried up.

v. Less than 10 per cent of the inland drainage is formed by the inland drainage of Rajasthan desert, Aksai chin of Jammu and Kashmir.

B. A small enclosure or field of grassland, especially for horses. (Australia, New Zealand) A field of grassland of any size, especially for keeping sheep or cattle. An area where horses are paraded and mounted before a race and unsaddled after a race..

C. A sheep station is a large property in Australia or New Zealand, whose main activity is the raising of sheep for their wool and/or meat. In Australia, sheep stations are usually in the south-east or south-west of the country. In New Zealand the Merinos are usually in the high country of the South Island. 

D. Coral polyps are tiny, soft-bodied organisms related to sea anemones and jellyfish. At their base is a hard, protective limestone skeleton called a calicle, which forms the structure of coral reefs. Reefs begin when a polyp attaches itself to a rock on the sea floor, then divides, or buds, into thousands of clones.
