1. Landforms Prepared By: J Boy D. Tormentar

2. Identify common Landforms, how they form, definitions, and examples. C HAPTER I INTRODUCTION

3. Direction: Complete the following by writing the appropriate words or amounts in the answer blanks. Motivation: “Guess What?”

4. Theoretical Framework “SELF-DETERMINATION THEORY” Deci and Ryan, 1985-2008, and Przybylski et al., 2013’s

5. Activity Group Activity: Paint me a picture! Direction: The entire class will be divided into four groups; each group will have to choose from the pictures we already have and draw/paint it using the provided art materials. One or two representative each group will explain why your group chose that picture to be drawn. It can be any collaborative story or experience that you can share with the class.

6. Analysis 1. Are you happy with the activity? 2. What do you think this activity is for? 3. Does Landforms and knowledge about these important? Why.  

7. Abstract  

8. Definition: A deep, narrow passage bounded by steep cliffs on both sides. Canyons are like valleys but with much steeper walls. Formation: Canyons form due to erosion by running water. The running water may be seasonal and only flow for a few months of the year, or flow year-round.

9. Definition: An naturally formed, underground chamber, below the earth’s surface or on the side of a hill or cliff. Formation: Many caves are formed by erosion. Caves can form when slowly seeping groundwater dissolves buried rock leaving behind hollowed-out caverns. For example, the rock limestone dissolves when in contact with mildly acidic groundwater. Erosion can also form caves when waves carve sea caves into cliffsides.

10. Definition: A steep rock face where the lands’ surface abruptly drops off. Formation: Cliffs form due to erosion from forces such as running water, ocean waves, groundwater seepage, or ice.

11. Definition: A rounded, naturally elevated area of land. Formation: Hills form in many ways. Some hills form as formerly larger mountains erode. Some hills form when sediments are deposited and then colonized with plants, such as the hills left behind in areas once covered by glaciers. Some hills form due to plate tectonic activity.

12. Definition: A body of land surrounded by water. Islands are smaller than continents and can be found in many types of water bodies such as oceans, lakes, and rivers. Formation: Islands may be formed by volcanic activity or by the deposition of sediments like sand. Plate tectonics also play a role – where ocean plates converge, uplift and volcanic activity occurs – increasing the elevation of the ocean floor until it breaches the water’s surface, forming islands.

13. Definition: A narrow strip of land with water on two sides, connecting two bodies of land. Formation: Isthmuses form when the water level exposes an elevated ridge of land above the water’s surface. Some isthmuses, such as the Isthmus of Panama, form where tectonic plates converge. Others, like the Madison Isthmus, are a result of the lakes and glacial drumlins (ridges of loose rock and coarse sediment deposited by glaciers) left behind in a post-glacial landscape.

14. Definition: A naturally elevated, flat-topped area of land with steep sides. It is larger than a butte, but smaller than a plateau. Formation: Mesas form as running water erodes away the rocks and sediments surrounding an area, leaving it elevated above the surrounding landscape. A “capstone” made of a harder rock than the surrounding area may prevent the mesa itself from eroding away as quickly.

15. Definition: A steep, naturally elevated area of land. It typically has high relief and may have exposed bedrock. Formation: Mountain ranges form when two tectonic plates collide together. This may occur on coasts or in the middle of continents. Mountains experience lots of precipitation, which causes them to slowly erode away.

16. Definition: A body of land that sticks out into a body of water. It is mostly surrounded by water and connected to a larger landmass on one side. Formation: Peninsulas form when the water level exposes an elevated ridge of land above the water’s surface.

17. Definition: A hill of loose sand commonly found near oceans and in deserts. Formation: Sand dunes form when lots of loose sediments are deposited in an area and rearranged into asymmetrical mounds by the wind.

18. Definition: A low area of land between two hills or mountains. Valleys often have streams flowing through them. Formation: Valleys are formed by erosion. Running water or glaciers can carve out valleys over long time periods. Flowing water tends to cut “V” shaped valleys, while glaciers carve out “U” shaped valleys.

19. Definition: A mountain or hill with a crater through which lava is projected. Formation: Volcanos typically form due to plate tectonic activity, which can allow the molten rock to breach the earth’s surface. The buildup of solidified lava forms a cone with a crater in it.

20. Application 1. What did you learned about the lesson? 2. Do you think it’s important for us to differentiate one Landform from the other? In what sense and why?  

21. IV. Evaluation Essay Writing: In all the Landforms we have discussed, what’s the most useful and plays a great role for you? Why? (10 pts.)

22. V. Agreement Direction: Do research and on a sheet of pad paper, list not less than 10 Waterforms and its definitions. (10 pts.)
