A Constructive Force or Process is one that builds up the **//__surface features__//** of the Earth. //__**Surface features**__// are landforms and bodies of water that cover the Earth's surface.
 * //__Constructive Forces __// **

//__**Surface features include**__ //: mountains, valleys, canyons, gorges, beaches, sand dunes, barrier islands, flood-plains, volcanoes, oceans, lakes, and rivers. Watch the following Study Jams Landforms to learn more about landforms and how they were formed.

//**How Can a Surface Feature be Changed by a Constructive Force? **//
 * The movement of the Earth’s crust through __//**Plate Tectonics**//__ [[image:mccurry1stqtrscience/Erosion_deposition.jpg width="565" height="478" align="right" caption="Notice the deposited soil in this picture."]]
 * Natural forces such as wind, water, ice, through the process of __//**deposition**//__. Deposition usually follows the process of **__//erosion//__**.

__//**Deposition**//__ is the process of dumping sediment, dirt, rocks, or particles in a new place from where it came from.

__**Examples of deposition include: **__
