the picture below shows a floodplain alongside a river channel. a floodplain is a flat landform created by deposition on the bottom of a wide river valley.

over time, a river gradually shifts its position back and forth across a valley bottom. as it shifts, it drops sediment to gradually build up a flat floodplain.

as the landform's name implies, another process plays a role in floodplain formation. which of the following describes this process?

a) acid rain weathers large rocks until they form a broad, flat plain.

b) glaciers move through a river valley every winter and flatten out the landforms.

c) a river may flood its valley and form a permanent inland sea.

d) a river floods over its channel banks and deposits sediment on the wide valley bottom.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.

it was given as a lesson and guide for prayer.
