1. Landforms Bodies of water WHY?? Earth’s Features!
Objective: Be able to identify and describe the earth’s features and the processes
that form and shape them.
Possible reasons:
It is required by the state of Texas.
By understanding your environment and having
knowledge about what affects it and how it affects you,
you become a more informed citizen, and in our country
we all have a responsibility or at least an opportunity
to vote on issues and have the freedom to start businesses
in which this knowledge could well be beneficial.
3. On a more personal and current note, this will be on a test! 
WHY??
Bodies of water

2. What do you already know? What do you need to know?
Get your pen and paper ready. The next few slides are
an effort to evaluate knowledge you may already have
and also to introduce things you don’t already know.
You will be given a definition or description of a landform
or body of water. Practice note-taking by bulleting the
important information from the slide, and if you know the
feature being described, label it!
The definition will be followed by a picture of the actual
feature– some of you will figure out the feature from this
slide. Try to add a quick sketch to your notes.

3. A natural elevation of the earth's surface having considerable mass, generally steep sides, and a height greater than that of a hill.

4. Mountain Put a bunch of them together and you have a mountain……. range
*considerable mass?
Mountain
*steep sides?
*higher than a hill?
Put a bunch of them together and you have
a mountain…….

5. A narrow channel joining two larger bodies of water.

projecting into
a body of water.

11. A usually triangular mass of sediment, especially silt and sand, deposited at the mouth of a river.
*They are usually crossed by numerous streams and channels and have exposed as well as submerged areas.

12. delta Related terms- Estuary-
1. The wide lower course of a river where it flows into the sea. Estuaries experience tidal flows and their water is a changing mixture of fresh and salt.
2. An arm of the sea that extends inland to meet the mouth of a river.
Mouth of a river-
Place where a river flows
into a larger body of water.

13. World History moment…. A Greek letter sits at the mouth of many rivers
World History moment…. A Greek letter sits at the mouth of many rivers. Notice the
resemblance between the island formed by sediment at the mouth of a river such as
the Nile and the triangular shape of their letter delta. The Greeks gave the name delta
to such an island. English borrowed this sense from the Greek, although the word delta
appeared first in English as the name of the letter, in a work written possibly around 1200.
The sense “alluvial deposit” is not recorded until 1555 when delta is used in reference to the
Nile delta.

15. Valley

16. A large area of a sea or ocean partially enclosed by land, especially a long landlocked portion of sea opening through a strait.

17. Gulf

18. A group of many islands in a large body of water.

19. archipelago island another island and another one okay, one more!
and finally

20. A ring-like coral island and reef that nearly or entirely encloses a lagoon.

21. atoll
lagoon

22. A long, narrow, deep inlet of the sea between steep slopes.

23. fjord

24. A steep slope or long cliff that separates two relatively level areas of differing elevations.

25. Also described as a steep cliff or slope.
escarpment

26. A large or high waterfall.

27. Cataract Also a cataract…

28. A stream that flows into a larger stream or other body of water.

29. Larger river
Smaller river
Tributary

30. A large piece of land
surrounded by water
on three sides.

31. Peninsula

32. A huge mass of ice slowly flowing over a land mass.

33. Glacier

34. A flat area resulting from repeated deposits of alluvial material by running water.

35. Alluvial plain
Note: alluvial soil - a fine-grained fertile soil deposited by water flowing over flood plains or in river beds.

36. An artificial waterway or artificially improved river used for travel, shipping, or irrigation.

37. It’s a man made feature across what
kind of landform?????
Panama Canal

38. 1. A hill that rises abruptly from the surrounding area and has sloping sides and a flat top.
2. A broad, flat-topped elevation with one or more cliff like sides, common in the southwest United States.

45. bay

46. A body of (usually fresh) water surrounded by land.

47. Lake

48. A ravine formed by a river in an area with little rainfall.
P.S. A ravine is a deep narrow steep-sided valley (especially one formed by running water).

49. Canyon

50. The next question is, how are landforms
formed and shaped?

51. External Forces *weathering - chemical - physical *erosion
Internal Forces
*plate tectonics
-collide
-move laterally
-pull apart
Read Chapter 4
Section One
pp.63-69

52. To finish out our objective, your next job
is to apply knowledge of internal
and external forces to their effect on the
Earth’s features.
For each landform we have just defined,
identify and explain the internal and/or
external process that formed it or
continues to shapes it.
Then, identify a real world example for each landform AND body of water.
I think maybe the kids could possibly brainstorm at this point, I didn’t include everything on the list, but I can add them if you think I missed something essential.

53. You can create a chart……
Let’s practice: How is a canyon formed?
Name a real world example of a canyon.
A canyon is formed by weathering and
erosion. Water breaks down the rock and carries it
away.
The Grand Canyon in the western U.S. is a “grand”
example.
You can create a chart……

54. What forms/shapes landforms?
TECTONIC PROCESSES
WEATHERING/EROSION
Canyon ex. Grand Canyon created by
weathering and erosion from the Colorado River.
