This document discusses various types of geographic features on Earth. It describes continental relief forms like plains, plateaus, mountains and depressions. It also explains coastal relief features such as capes, gulfs, peninsulas, estuaries, fjords and deltas. Additionally, it outlines submarine relief including mid-ocean ridges, abyssal plains, and marine trenches located on the ocean floor.

2. Continental Relief
• Relief refers to all the different forms on Earth´s
surface. The different types of continental (surface)
relief are plains, plateaus, mountains, and
depressions.

4. Peninsula
• Area of land surrounded by water on all sides but
one (the isthmus) which joins it to the mainland.

5. The Florida Peninsula
• Situated between the
Gulf of Mexico, the
Atlantic Ocean, and the
Straits of Florida

6. Mountain
• Elevation of the terrain with steep slopes and an
altitude of greater than 600 m.

7. The Himalaya Mountains
• Crosses several
countries in Asia:
– India, Nepal, Tibet,
Bhutan, Pakistan
• World’s highest
mountain system

8. Plain
• Flat or gently rolling extension of land at an altitude
of less than 200 m.

9. The Great Plains
• Located in the United
States and covers 10
American States and
part of Canada

10. Plateau
• A raised plain at an altitude of over 200 m.

11. The Tibetan Plateau
• Located in Asia
• The largest and highest
plateau in the world
• Nicknamed the “roof of
the world”

12. Depression
• Sunken area of the Earth´s crust

14. Coastal Relief
• Capes, gulfs, peninsulas, estuaries, fjords, and
deltas.

16. Cape
• Part of the coast which juts out into the sea.

17. Cape of Good Hope
• Located in Cape
Peninsula, South Africa
• 1488: Bartolomeu Dias
rounds the Cape

18. Gulf
• Entry of the sea into the coast.

19. Gulf of Mexico
• Connected to the
Atlantic Ocean
• 10th largest body of
water in the world

20. Delta
• Coastal area formed by the accumulation of
sediments of a river at its mouth.

21. Mississippi River Delta
• Mississippi River is the
4th longest and 10th
largest river in the world
• Delta enters the Gulf of
Mexico

22. Island
• Mass of land surrounded by water.

23. The Canaries!
• Located in front of the
northwest coast of
Africa

24. Estuary
• Flooded valley formed by the entry of the sea into
the final section of a river valley.

25. Gulf of St. Lawrence Estuary
• World’s largest estuary
• Rivers that flow into it:
– St. Lawrence, Miramichi,
Natashquan,
Restigouche, Margaree,
Humber
• Flows into the Atlantic
Ocean

26. Submarine Relief
• AKA underwater relief. Continental platforms,
continental shelves, and abyssal plains, across
which mid-ocean ridges and marine trenches can be
found.

28. Mid-Ocean Ridge
• Underwater mountain range

30. Abyssal Plain
• Extensive, flat sea bottom at a depth of 4,000 to
5,000 m.

32. Marine Trench
• Long, narrow underwater depression.

34. Continental Trench
• Long, narrow surface depression above water.

36. Continental Platform
• AKA continental slope. Gentle slope at the edge of
the continent with a depth of 200 m.
