Meandering is defined as bending of longitudinal course of rivers. Choose the correct statement(s) regarding this.
(1) Convex side of valley wall is called slip-off slope a site of deposition.
(2) All streams meander in all types of terrains.
(3) Degree of deviation of observed path from expected path is known as sinuosity index.
(4) Incised meanders unlike simple meanders are always dug out in bed rocks.

Regarding depositional land forms by river, choose the correct statement(s).
(1) Alluvial fanes and all alluvial cones are formed at foothills.
(2) Both differ from each other only in terms of gradient.
(3) Ridge of low height built by deposition of sediments by spill of stream on its either bank is called natural leave.
(4) Whether small or large, almost every river forms delta.

Which of the following processes are a method to transport river load?
(1) Traction
(2) Suspension
(3) Solution
(4) Siltation

Plants growing in areas of high temperature are called ______.

Fluvial erosion is one of the most important exogenetic processes. On what factors does it depend?
(1) Channel gradient  (2) Volume of water
(3) Velocity of flow   (4) Water discharge   (5) Sediment load

Terraces are step like flat surfaces on either side of the present lowest valley floors. Choose the correct statements regarding this.
(1) Structural terraces differ from river terraces in terms of dominant role played by lithology.
(2) River terraces are generally formed due to dissection of fluvial sediments of flood plains.
(3) Paired terraces are formed due to rapid rate of vertical erosion.
(4) Unpaired terraces are formed due to concomitant vertical erosion and lateral movement of channel.

Sea waves are generated due to friction of water surface caused by blowing wind. Choose the correct statement regarding sea waves.
(1) Undulations of sea water at the place of their origin are called swells.
(2) Height of winds generated depends on wind speed, duration of wind in one direction, length of water surface over which the wind blows.
(3) Wavelength is expressed in terms of unit of meters.
(4) Wave velocity is directly related to wavelength.

Which of the following is/are not erosional land forms?
(1) Cliff
(2) Caves
(3) Wave-cut platform
