Which conditions I think you have place an incorrect image?
Answer:
A. The upward pressure gradient force is balanced by gravity.
Explanation:
A. is correct because the pressure difference is actually generated by gravity. As in the following formula for the pressure at different points:
where are the pressure at 2 points, ρ is the density of the fluid, g is the gravitational constant, and h is the height difference.
B is incorrect because friction in air is too small to make an effect.
C is incorrect because the Coriolis force is horizontal, not vertical.
D is incorrect because a difference of 500 hPa = 50000 Pa, this is half of the atmospheric pressure.
E is incorrect because temperature cannot generate force.
It would be B, the weather patterns outside.
Answer:
Meandering
Explanation:
A meander is known as the continuous flow of regular curves which are sinuous, loops, turns, bends or winding in the channel of river
Production of a meander by a river or stream as it erodes the sediments comprising on an exterior, a concave bank and deposits it and other sediment on the downstream on an interior, convex bank which is like a point bar.
Rivers or streams with a one channel and sinuosities of 1.6 or more are defined as meandering rivers or streams.
