THIS IS AN EXAMPLE OF?

WATERFALLSHOW ARE WATERFALLS FORMED?A RIVER FLOWS OVER AN AREA OF HARD ROCK THAT ERODES SLOWLY, THEN OVER A SOFT ROCK THAT ERODES MORE QUICKLY.

WHAT IS THIS AN EXAMPLE OF?

THIS IS AN EXAMPLE OF?

MEANDERWHAT CAUSES A MEANDER?WATER FOLLOWS THE COURSE OF LEAST RESISTANCE. IT WILL FLOW FIRST WHERE ROCK/SEDIMENT IS EASIER TO ERODE.

WHAT IS THIS AND WHY DID IT FORM?

OXBOW LAKEUSUALLY FORM DURING FLOODS WHEN WATER FINDS AN EASIER WAY DOWNSTREAM AND CUTS OFF THE OLD MEANDER.

WHAT IS THIS AN EXAMPLE OF?

ALLUVIAL FANSSTREAMS FLOW OUT OF A STEEP NARROW MOUNTAIN VALLEY AND SUDDENLY SPILL INTO AN OPEN, FLAT AREA OR WATER SOURCE

WHAT AND WHERE?

DELTAEXPLAIN HOW A DELTA IS FORMED.SEDIMENT THAT IS DEPOSITED BY A RIVER THAT FLOWS INTO A LAKE OR OCEAN BUILDS UP INTO A LAND FORM.
