Welcome To Niagara Falls!

In This Earthcache You Will Learn Alot About The Rapids Above And Below The Falls.

Wikipedia States "Rapids are sections of a river where the river bed has a relatively steep gradient, causing an increase in water velocity and turbulence."

Rapids are hydrological features between a run (a smoothly flowing part of a stream) and a cascade. Rapids are created by the river becoming shallower with some rocks being exposed above the flow surface. Rapids occur in spots where the bed material is very resistent to the erosive power of the stream in comparison with the bed downstream of the rapids. Young Streams Flowing across solid rock are usuallly rapids for most of their length. Rapids cause water aeraration of the stream or river resulting in better water quality.

There Are Many Different Types Of Rapids/Streams:

Reach:

A reach is a length of a stream or river, usually suggesting a level, uninterrupted stretch

Riffle:

Riffles are shallow with fast, turbulent water running over rocks. Runs are deep with fast water and little or no turbulence.

Whitewater Rapids

Whitewater is formed in a rapid, when a River's gradient increases enough to generate so much turbulence that air is entrained into the water body, that is, it forms a bubbly or aerated and unstable current; the frothy water appears white.

1. Go to the posted coords and look at the top of the falls. what type of rapids are these?

2. Look At The Bottom, What Type Of Rapids Are These?

3. Look Around, How Does The Depth of The Water Affect The Rapids?

(Optional) Post A Photo Of Yourself At The Falls!
