Types of relief

5. TYPES OF RELIEF CONTINENTAL RELIEF -MOUNTAINS: - very high elevations of the Earth’s surface.

- MOUNTAIN RANGES: when mountains are grouped together.

- PLATEAUS: high flat areas that are formed from eroded mountains.

- PLAINS: - low flat areas.

- They are fertile for agriculture due to the sediments deposited in them.

- ALLUVIAL PLAINS: are formed by rivers - COASTAL PLAINS: are near the sea.

- BASINS: - very low areas.

- some of them are below sea level (Dead Sea)

5. TYPES OF RELIEF RELIEF ON THE OCEAN FLOOR -

CONTINENTAL SHELF (Plataforma continental): - - Is a great underwater plateau that surrounds a continent.

- It is less than 200 metres deep

-

ABYSSAL PLAINS (Llanuras abisales): -

-

TRENCHES (Fosas oceánicas): -

-

Like cracks in the Earth’s surface, but in the ocean floor.

The deepest trench, Mariana Trench, in the Pacific Ocean, 11,000 metres deep.

OCEAN RIDGES ( Dorsales oceánicas) -

-

Huge underwater plains.

More than 4,000 metres deep.

Similar to mountain ridges, but in the ocean floor.

CONTINENTAL SLOPE: -

Sloping terrain that connects continental shelf to the abyssal plains.
