                              Constructive Forces

 

Constructive forces are forces that build up the earth like the forces make mountains by uplift.

 

                           

 

When a volcano erupts it may burn things,but when the lava dries it turns into igneous rocks. That is building up the earth.

The faults can move in different directions and that can cause landforms and that builds up the earth. Also glaciers because they make morains.

 

                                Destructive Forces

 

Destructive forces are forces that weather things like rocks. Weathering is destructive because it breakes rocks but very really

 

slowly. Ice, water, and wind are all sorts of weathering but it is very slow. Earthquakes are constructive and destructive and very fast. Because earthquakes are the tectonic plates moveing past eachother really quickly and that causes faults and folds. The faults is breaking. Fault lines are cracks on the earth's surface. Tectonic plates can move in three ways. They can move away from eachother, away from each other, or different dirrections.
