Constructive and Destructive processes, landforms, weathering, erosion, deposition - EARTH SCIENCE
Earth's surface is always changing. Some changes take thousands of years. Other changes happen within minutes. These surface changes are caused by constructive and destructive processes. Constructive processes build up the Earth's surface. Destructive processes tear down the Earth's surface. Sometimes humans use technology to alter or interfere with changes in the surface of the Earth.
Over time, the Earth's rocks get broken down into smaller pieces. This is called _________________

A river drops sediment at it's mouth, forming a delta
Through the seasons, the wooden bench cracks and splits
As the glacier moves slowly across the land, it picks up bits of rock that grind on the Earth's surface.
A dune is formed when the wind slows and drops sand in a pile
A glacier melts and leaves behind cliffs and valleys
