How do rivers change the land?

Answer 1

Rain, hail, or possibly snow can hit the banks of the river hard enough that it can chip away the river banks. Over many years of this, the river banks will become lower in altitude, causing the river to be wider and most likely shallower.

Answer 2

Water is a powerful landscaper. Water can weather and erode rock over many years to create new structures or wear them down. One example of water's ability to drastically change the land, is the Grand Canyon. The Colorado River over thousands of years had weathered and eroded the rock as the land was pushed upward from below. The river "cut" through the rock, and created the Grand Canyon.

Torrential rains can cause flooding. Heavy flooding can be destrucive and can uproot trees, carry and toss rocks, and destroy habitats. Rain could turn a calm stream into a raging river that can pick up debris from the river bed, bashing them into the surrounding area.

Water can freeze in between rocks and when it expands, this process of expanding in the rocks over years can change mountainous regions. It can over time reduce their size(from the rocks that fall or slide off).

Glaciers can turnlow-lying hills into deep valleys as they move along slowly over the years. Glaciers oftern "pick up" rocks as they move along, and this is from their "cutting' through the ladnscape.

Earthquakes under the ocean or sudden displacements can cause tsunamis. Tsunamis are powerful waves that can destroy a beach and the land behind it. These massive waves can overcome and submerge small islands or even barrier islands.

These are just a few of the common ways in which water can change the landscape.

Answer 3

Water can cause a rivers bank to change but it takes time. As time goes on, the water is slowly reforming the way the land is sitting, with which way the water flows.

Answer 4

Well, A river erodes its bed because of erosion of course!. Its all go to do with Hydraulic actions, abrasion, attrition and soluting working in underlying rivers to erode river beds.

Answer 5

well running water can change land by taking sand and changing the shape of the land

Answer 6

the banks get wider because the water keeps moving.

Answer 7

Water can change the land with erosion, which is when water slowly wears down the ground it flows over by picking up some of the dirt and soil and depositing it somewhere else.
