Landforms re Grade 7 Geography

2. • It’s time to ‘brain storm’ everything you know
about “landforms” (the type and description). With
your partner list anything that comes to mind.
Remember there are no wrong ideas. Be
prepared to share you great ideas with the class.

5. Now let’s take a look!

6. Did you storm “Glacier”
https://www.youtube.com/watch?v=fleXP9ljZ-o
a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds
its ablation (melting and sublimation) over many years, often centuries. Glaciers slowly deform and flow due to stresses induced
by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate
to create landforms such as cirques and moraines. Glaciers form only on land and are distinct from the much thinner sea ice and lake
ice that form on the surface of bodies of water.

7. How about “Lowlands”?

8. from The American Heritage® Dictionary of the English Language, 4th Edition
n. An area of land that is low in relation to the surrounding country.
adj. Relating to or characteristic of low, usually level land.

9. How about “mountains’?

11. “Plains”
In geography, a plain is a flat area. Plains occur as lowlands and at the bottoms of valleys but also on plateaus or uplands at high elevations. In a
valley, a plain is enclosed on two sides but in other cases a plain may be delineated by a complete or partial ring of hills, by mountains or cliffs.
Where a geological region contains more than one plain, they may be connected by a pass (sometime termed a gap). Plains may have been
formed from flowing lava, deposited by water, ice, wind, or formed by erosion by these agents from hills and mountains.
Plains in many areas are important for agriculture because where the soils were deposited as sediments they may be deep and fertile, and the
flatness facilitates mechanization of crop production; or because they support grasslands which provide good grazing for livestock.

12. NOT “PLANES” !

13. “Shields” of course.

14. OOPS! “Shields” LOL
A shield is generally a large area of exposed Precambrian crystalline igneous
and high-grade metamorphic rocks that form tectonically stable areas.[1] In all
cases, the age of these rocks is greater than 570 million years and sometimes
dates back 2 to 3.5 billion years.[2] They have been little affected by tectonic
events following the end of the Precambrian, and are relatively flat regions
where mountain building, faulting, and other tectonic processes are greatly
diminished compared with the activity that occurs at the margins of the shields
and the boundaries between tectonic plates.

15. https://en.wikipedia.org/wiki/Valley
A valley is a low area between hills, often with a river running through it. The Valley of Marvels in
Babille, Ethiopia. In geology, a valley or dale is a depression that is longer than it is wide. The terms
U-shaped and V-shaped are descriptive terms of geography to characterize the form of valleys.
