Elements of relief
- 2. a)Mountains chains: very high elevations - Mountains ranges (high and sharp) -cordilleras- - Massifs: Old mountains ranges (round) -macizos- a)Plateaus: high flat areas - Mesas or p叩ramos. - Peneplain -penillanura- c) Plains: low flat areas. - Alluvial plains (rivers) - Coastal plains (sea) d) Basins: low areas below sea level. e) Valleys: - Glaciar Valleys U-Shape - River valleys V-Shape - Cannons
- 3. Young mountains chains: high and sharp (current tectonic plates contact) Sharp and high +3500 metres. The Alps, Switzerland
- 4. Old mountains chains (round, eroded) Old tectonic contact. Old round Mountains chains 900 metres Ourense Galicia
- 5. Plateau: High flat areas from eroded mountains (more than 500 metres). Wide high plain slope Harder layers
- 6. P叩ramo or mesa (isolated plateau, or reliefs with flat peak) Flat peak More paramos Colorado USA
- 7. Very flat land, usually less than 300 metres high.
- 8. Hilly plain, with river valleys, and not completly flat (llanura con colinas) 350 metres Over sea valleys Old mountain chains Hills C叩ceres
- 10. Very low areas, sometimes below sea level, usually in wide river valleys. Ebro Basin, Arag坦n
- 11. U-shape valley
- 12. Narrow valleys in the mountain chains, formed by rivers.
- 13. 1. Coastal plain (beginning of the continental shelf) 2. Cliffs (sharp end of coastline) 3. Capes (narrow portion of land entering in sea) 3. Gulfs (big) and bays (small). (water entering in land) 4. Peninsulas (land entering in water) 5. Archipelagues (group of islands) 6. Atoll (atol坦n) 7. Straits. (lands narrowly divided by water)
- 14. Padre Island Texas, USA This plains are caused by proximity to Continental shelf. Very low areas Flat land
- 15. Gulf of M辿xico USA M辿xico Peninsula Florida Peninsula Yucat叩n Bahamas Archipelague Texas & Louisiana Coastal plain
- 16. Cliffs: sharp ending of the continental land. Mohen, Ireland Layers of Sedimentary rocks
- 17. Narrow portions of land entering into the sea.
- 18. Portion of water surrounded partialy by the coastal line. Bay or Harbour.
- 19. Gulf of M辿xico USA M辿xico Peninsula Florida Peninsula Yucat叩n Bahamas Archipelague Texas plain Portion of water surrounded partialy by the continent, (much bigger than a bay).
- 20. Piece of land almost entirely surrounded by Water. Iberian Peninsula.
- 22. Group of islands in the sea or ocean. Canarias islands
- 24. a) Continental shelf: underwater plateau 200 m. deep b) Abyssal plain: underwater plateau + 4000 m. deep. c) Continental slope: the slope between both of them. d) Trench (fosas): very deep, in the contact of tectonic plates. e) Ridges (dorsales oce叩nicas): mountain ranges in the oceans.
- 25. Continental shelf: plain behind the water of the sea, quite hollow
- 27. Continental slope: end of the continental shelf, falling To the abbysal plain. Continental slope
- 28. Trench (fosa) Abyssal plain, very deep (+4000 metres)
- 29. 4. Ocean Ridge Lava in ridges Mountain chains in the middle of the ocean, created by the Division of tectonic plates.
- 30. Deepest places in the oceans, more than 8000 metres.
