a)Mountains chains: very high elevations- Mountains ranges (high and sharp) -

cordilleras-- Massifs: Old mountains ranges (round) -

macizos-b)Plateaus: high flat areas

- Mesas or páramos. - 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”

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 (atolón)7. Straits. (lands narrowly divided by

water)

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 oceánicas): mountain ranges in the oceans.
