4. Definitions:
Landform: Physical shapes of the land. Examples: hillsides, cliffs, marshes, etc. Wetland: Are areas characterized by a high proportion of water and watery land Marsh: a wetland area dominated by grasses, while a swamp is designated by trees.

Use this handout to complete the procedure on page C-5, using the pictures provided on page C-6.

9. What were observations and what were inferences??
Example:
Observation
Inference
Wetlands have been filled in and have less water
This has been bad for wildlife in the area

10. Analysis Questions Landform examples include: Valleys Canyons Plateaus
Mountains
Buttes
Mesas
Arches
Etc.

11. A. Marsh: Hillside: Cliff No longer any water Ground became solid
No more birds
Grasses and tree species replaced
Hillside:
Trees were replaced by roads and houses
Earth surface has fewer peaks and valleys
Cliff
House is built on top of cliff
Cliff seems to have crumpled near the house
Coastline seems to be less straight and barriers were added

12. A. Weather: amount of rainfall, because heavy rain could wash away the hills or the cliff and could flood the wetlands
Animals: animals could be endangered if construction destroys the habitat
Plants: plants could become scarce or endangered. Plants also prevent erosion by absorbing water and stabilizing earth with their roots
Housing Prices: Prices may go down if there is more housing available, or if the construction makes the area less attractive
Shape of the land: some landforms are not safe/difficult to build on
