Q:

Statement I :

Incised meanders are formed in the mature stage of a river.

Statement II :

Incised meanders are characterized by rejuvenation and upliftment of land.

A) Both the statements are individually true and Statement II is the correct explanation of Statement I	B) Both the statements are individually true but Statement II is not the correct explanation of Statement I
C) Statement I is true but Statement II is false	D) Statement I is false but Statement II is true

Answer & Explanation Answer: D) Statement I is false but Statement II is true

Explanation:

Rejuvenation occurs when the river’s base level falls (i.e. when sea level falls). This can be a consequence of either a fall in the amount of sea water or the land rising. Incised meanders are meanders which are particularly well developed and occur when a river’s base level has fallen giving the river a large amount of vertical erosion power, allowing it to down cut. Hence, 2nd statement is correct.

There are two types of incised meanders, entrenched meanders and ingrown meanders.As they are products of rejuvenation, they are not formed in mature stage of a river

Q:

Which one of the following may be the true characteristic of cyclones?

A) Temperate cyclones move from west to east with westerlies whereas tropical cyclones follow trade winds	B) The front side of cyclone is known as the 'eye of cyclone'.
C) Cyclones possess a centre of high pressure surrounded by closed isobars	D) Hurricanes are well known tropical cyclones which develop over mid latitudes.

Answer & Explanation Answer: A) Temperate cyclones move from west to east with westerlies whereas tropical cyclones follow trade winds

Explanation:

Temperate Cyclones are cyclones of mid-latitudes and hence are primarily under influence of permanent winds of mid-latitudes i.e. westerlies. Their movement is therefore eastwards of their origin with average velocity of 32km per hour in summers and 48km per hour in winters.

Movement of Tropical CyclonesNormally, they move from east to west under the influence of trade winds because trade winds are permanent winds of tropical latitudes. The general direction is therefore westwards from their origin. They advance with varying velocities. Weak cyclones move at the speed of about 32km per hour while hurricanes attain the velocity of 180km per hour or more.
