Q.151. Ria Coast is an example of –
(A) Deposited land features
(B) Compound shore
(C) Emerged upland shore
(D) Sub-merged upland shore
Answer: D
Explanation:
| Ria coasts | Fiord coasts |
| Ria coasts are formed due to submergence of river valleys | Fiord coasts are formed due to submergence of glaciated valleys. When the glaciers melt sea water get mixed with the melted ones to give rise to fiord coasts. |
| Ria coast the depth increases seawards, coasts are shallower than the adjoining sea | Fiord coasts the depth decreases seawards,
coast is deeper than the adjoining sea. |
| Ria coasts can be found in all latitudes. | Fiord coasts are found in the high latitudes, fiord coasts are glaciated which is possible only in high latitudes. |
| The Kingsbridge Estuary in Davon, England is an example of Ria coast. | Fiord coasts are found in plenty in Scandanavian countries such as Norway. Norway is also known as country of fiords. |

(A) Fluvial Deposition
(B) Plate Tectonic
(C) Periglacial Processes
(D) Process of Soil Formation
Answer: C
Explanation:
Active Layer
The top layer of permafrost is called active layer which is characterized by diurnal freeze (during night) and thaw (during day time) cycle during the intervening periods of summer and winter seasons. It is completely frozen during winter and is thaw during late summer.
The depth of active layer ranges from a few centimeter to 3 metres.

Q.175. The most common type of mass movements found in the humid tropics is
(A) Sheet Wash
(B) Solifluction
(C) Rock fall
(D) Soil Creep
Answer: D
Explanation:
Soil Creep – this is the slowest type of Mass Movement.
It is probably the most common type of MM in Ireland and despite it’s slowness it can have significant impacts over time
Main Processes Involved – Freeze Thaw, wetting and drying
These processes cause the soil to expand (freezing, wetting) and shrink (thawing, drying) – eventually the soil moves downhill
As little as 1mm of movement per year movement
Soil Creep is a relatively dry type of movement – the soil “rolls” rather than “flows” downhill
