Coastal Geomorphology

Options:

1. Sea shore represents the actual landward limit of sea water at a given moment while sea coast represents the land zone immediately behind the cliff.
2. Sea coast represents the actual landward limit of sea water at a given moment while sea shore represents the zone of land between high tide water and low tide water.
3. Sea shore represents the zone of land between high tide water and low tide water while sea coast represents the cliff-line or the margin of land rising above the sea water.
4. Sea coast and sea shore are synonyms and have the same meaning.

Correct Answer

Options:

1. Weathering, decomposition, and hydraulic pressure

3. Stability of the coastline
4. All of the above

Correct Answer

Options:

1. The impact of moving water on coastal rocks
2. The chemical alteration of rocks mainly carbonate rocks
3. The mechanical tear and wear of fragments due to their mutual collision
4. The alternate processes of wetting and drying of coastal rocks

Correct Answer

Options:

1. Hydraulic action
2. Corrosion or solution
3. Abrasion or corrasion
4. Attrition

Correct Answer

Options:

1. Abrasion
2. Corrosion
3. Quarrying
4. Solution

Correct Answer

Options:

1. Marine erosion at the base of the cliff is much faster than the subaerial weathering of cliff face and crest
2. The subaerial processes dominate over marine processes
3. The impact of moving water on coastal rocks
4. The alternate processes of wetting and drying of coastal rocks

Correct Answer

Options:

1. Cliffs
2. Coves
3. Deserts
4. Wave-cut platforms

Correct Answer

Options:

1. Chemical erosion

2. Only rock lithology and structure
3. Both and
4. All of the above

Correct Answer

Options:

1. A rock-cut flat surface in front of cliffs
2. A type of beach with steep cliffs

Correct Answer

Options:

1. Quarrying, plucking and solution platforms
2. Inclined plane, stepped and storm wave platforms
3. Supralittoral, mesolittoral and sublittoral zones
4. None of the above

Correct Answer

Options:

1. Because they are more resistant to wave erosion
2. Because they are more susceptible to chemical erosion
3. Because they are more resistant to solutional processes
