An estuary is a land form where a river mouth runs into the ocean or sea.
A land form is a physical feature of the earth, such as a butte. Factors used to categorize a land form range from its elevation to the rocks or soil that make it up, to its relation to larger surrounding geographical features. Designing a land form project provides you a better understanding of how the area's smaller features shape its overall topography.
Instructions
1. Research different land forms from books on geology, geography or topography until you find one that interests you. Perform further research on the land form you select and write a single-paragraph definition. Include its external appearance, mineral composition, how it is formed and in what geographical regions in typically occurs.
2. Draw a cross-section illustration of a generic example of your land form, which will show the viewer what it looks like both on the inside and the outside. Label the features of the land form that distinguish it from others, such as the vertical or nearly vertical, rocky slope of a cliff. Also label the different kinds of earth that form it, such as limestone or topsoil.
3. Draw two pictures illustrating how your land form developed. For example, to show how a butte is formed, your first picture will show water or wind starting to erode the soft rock around capstone rock, such as sandstone. In the second picture, erosion will have washed away all the soft rock, leaving only the capstone, which now forms the butte. As with the previous diagram, label the important features, as well as the period required for the land form to emerge.
4. Print out pictures of three well known examples of your land form. Type out a title card for each, including its name, location and three other facts -- such as elevation, size or shape -- of your land form. Also include at least one cultural or historical fact about how the people who live around the land form interact with it, or in some cases try to avoid it, such as volcanoes or swamps.
5. Draw or print out a map of the world. Label the regions where your land form is found. Create a title card for this map naming and describing the geographical region. If your land form was a fjord, you would describe the geography of glacial regions, where huge, slow moving masses of snow and ice called glaciers carve out the different features of the earth as they move across it over hundreds of thousands, if not millions, of years.
6. Assemble all your materials and carefully glue or tape them to a three-sided display board. Complete the project by writing the name of your land form at the top in large letters.
