1. Shaping and reshaping

2.  Landforms are the natural features of the Earth’s surface.  They are the landscapes around us.  They are shaped by volcanoes, earthquakes, uplifts, weathering, and erosion.  These landforms have names.

3.  A valley is a hollow or surface depression of the earth bounded by hills or mountains, a natural trough in the earth's surface, that slopes down to a stream, lake or the ocean, formed by water and/or ice erosion.

4.  A plateau is a large highland area of fairly level land separated from surrounding land by steep slopes.

5.  Bowl shaped area of land that either does or used to hold water.

6.  Mountains are created by tremendous forces in the earth with a steep top usually shaped up to a peak or ridge.  Mountains occur more often in oceans than on land.  Mountains are formed by volcanism, erosion, and disturbances or uplift in the earth's crust.

7.  Plains are broad, nearly level stretches of land that have no great changes in elevation. Plains are generally lower than the land around them; they may be found along a coast or inland.  Coastal plains generally rise from sea level until they meet higher landforms such as mountains or plateaus.  Inland plains may be found at high altitudes.

8.  Hills are elevations of the earth's surface that have distinct summits, but are lower in elevation than mountains.  Hills may be formed by a buildup of rock debris or sand deposited by glaciers and wind.  Hills may be created by faults.

9.  Ice sheets and glaciers form the largest component of persistent ice on this planet.  Over 75% of the world's fresh water is presently locked up in these frozen reservoirs.

10.  A steep walled valley created by a river or a stream.

11.  Large body of water surrounded by land.

12.  Man made storage area for fresh water.

13.  Large natural stream that flows into a larger body of water.

14.  Part of river that empties into another body of water.

15.  Deposit of sediment where a stream enters a large body of water.

16.  A water ecosystem such as mud flats, swamps, and marshes.

17.  a broad inlet of the sea where the land curves inward.

18.  a very large expanse of sea, in particular, each of the main areas into which the sea is divided geographically.

19.  a pebbly or sandy shore, especially by the ocean between high- and low-water marks

20.  a piece of land surrounded completely by water.

21.  the expanse of salt water that covers most of the earth's surface and surrounds its landmasses.

22.  a narrow passage of water connecting two seas or two large areas of water.

23.  a deep inlet of the sea almost surrounded by land, with a narrow mouth.
