Moving water, like that of a river, carries sediment as it moves along its bed. the faster the water flows, the more sediment that is carried and the larger the sediment particles. as the river slows down, the heavier particles of the load will settle out. how can you explain the particle movement based on newton's laws of motion?

Well newton's law is esstenaily how gravity works. so the force in this case water moves, the more the object (sediment) will go farther. And when the force is lessened the object will eventually come to a dead stop. 

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
