Why rivers form meanders?

Question

(0) The chunks of tea leaves sink in tea.

(a) If a cup of tea is placed in the center of rotating
catousel, where will the chunks of tea leaves congregate?

(b) If tea is stirred inside non-rotating teacup,
where will the chunks of tea leaves congregate?
(this one can be easily verified if you care to
make a trip to cafeteria).

Answer 1

rivers "form meanders" due to several factors........ the lay of the land, gravity, obstacles. Water will seek the easiest path from high to low.
chunks of tea leaves in a cup on a carousel will go to the edges because of centrifugal force. A stirred cup's leaves will go to the bottom center.

Answer 2

B Deposition of sand on the two the interior and the exterior of bends in the river forces the channel to grow to be extra sinuous over the years. Meanders type because of the extra advantageous quantity of water carried through the river in lowland aspects which leads to lateral (sideways) erosion being extra dominant than vertical erosion, inflicting the channel to shrink into its banks forming meanders.

Answer 3

Then meander over the the cafeteria.

For a it would be the edges of the cup as the force of the spinning cause it to do that.
