Build Up or Break Down?
Contructive an Destructive processes
By: Cheyenne Irby
Build Up
Constructive Processes (Build Ups) are when something happens to the Earth that helps it instead of herting it. Its like, when a volcano erupts, after the lava dries upit makes new hills. Also when rocks break off and fall into the ocean, they break down into little peices and form sand, then the sand washes onto a beach, it all adds up.
The People Help
Us humans have had a hand in it too, its not all natural. One way we have helped is, losening soil by rivers, that way the river can pick up sediment and bring it to a new location.
Volcano Erupting
The hardened lava will make new hills.
Rocks Bits Breaking off
The rock bits will get smaller, become sand, then add to a diffrent beach.
Sand Dunes in Desert
The wind picked up the sand and made it into the dune.
Break Down
Destructive Processes (Break Down) are when something happens to the Earth that breaks that part of it. Like a Landslide, when it happens that part of the mountain breaks of, thus destroying it. Thats just the beginning...
The People Hurt
We have not only helped help the Earth, but we have also helped hurt it. One way we have helped hurt it is, building roads, when the cars are driving they make alot of noise, and that could cause a Landslide.
Landslide
Part of the mountain breaks off and that destroys part of it.
Earthquake
Some of the Plates (the things that make up land) rub against each other an it causes that area of land to shake and crack.
Erosion
Wind picks up sediment (tiny peices of rock) and carries it to diffrent places and leaves this.
