Why do we see yellow soil/lands near the mouth of the river?

• The soil accumulated (gathered) in those places.

• The soil is transported by flowing water.

• Rocks from the top of the mountain become smaller because of erosion by flowing water.

• The smaller rocks are transported by the flowing water.

• The smaller clay particles can fill some of the spaces between the sand particles.

• Bigger particles fill the bottom layer.

• Smaller particles fill the top layer.

• None of the above.
