Earth Science Review

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.

Match the words on the left with the correct description on the right

Draggable item		Corresponding Item
tornado		overflow of water on land that is usually dry
seismograph		storm with powerful wind and heavy rain
hurricane		fast spinning wind shaped like a cone
earthquake		to burst forth
delta		strong shaking of the ground
levee		hole created when rock and gasses burst through the earth's surface
erupt		machine used to study earthquakes
dam		landform created from deposition at the mouth of a river
flood		man-made structure built across a river to prevent flooding
volcano		man-made structure that runs along the sides of a river to help prevent flooding

Use the lyrics from the Weathering, Erosion, and Deposition Rap to help you identify the action in the examples below.

1

A river drops sediment at it's mouth, forming a delta

1

Through the seasons, the wooden bench cracks and splits

1

As the glacier moves slowly across the land, it picks up bits of rock that grind on the Earth's surface.

1

A dune is formed when the wind slows and drops sand in a pile
