1. Lateral Planation Theory of pediment formation was proposed by
(A) Lawson (B) Davis
(C) Gilbert (D) McGee
Lateral Planation Theory is discovered by Gilbert. Johnson talks about promotion of this theory. Sharp and Howard deals with its elaboration.
2. Match List 1 with list 2
List 1 (Books)
Essays in Geomorphology
An outline of geomorphology
List 2 (Authors)
Woolridge and Morgen
An outline of geomorphology is written by Woolridge and Morgen. Physical geography is written by Strahler. Essays in Geomorphology is written by Harry Dury. Geomorphology is written by Lobeck.
3. Which of the following is strongly presumptive faultline scrap?
a) superimposed drainage across a fault
b) poor correlation between rock resistance and topographic forms
c) frequent severe earthquakes
d) actual fault plane identified along the scrap
Fault line scrap is a cliff or escarpment resulting from the erosion of soft rock that has been brought against hard rock by faulting, therefore it is a poor correlation between rock resistance and topographic forms.
4. Paternoster lakes are features of:
a) lava plains
d) glacial troughs
A Paternoster lake is one of a series of glacial lakes connected by a single stream or a braided stream system
5. Match List 1 with list 2
List 1 (Theories of cavern Formation)
a. Two cycle theory
b. Water table theory
c. Static water zone theory
d. Invasion Theory
List 2 (Scholar)
Water table theory is given by Swinnerton and explains that rapidly moving water at the water table is responsible for the solution of most caves. Gardner based his “static water zone” theory of cavern development on the concept that dissection of permeable strata was responsible for initiating groundwater movement and solution of caverns. Malott gave the invasion theory of cavern development and maintained that most cavern development takes place above the water table where groundwater velocity is greatest. Davis gave the two cycle theory and said that cave initiation and most cavern enlargement occur at random depth below the water table while second cycle of cavern development may occur when the water table has been lowered by surface denudation.
6. Which one of the following processes is typical to glacial erosion?
(B) Hydraulic action
Plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of bedrock especially large joint blocks. As a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints in the bedrock.
7. Given below are two statements, one labelled as assertion (A) and the other labelled as Reason (R).
Assertion (A) : Deep chemical decay of rocks is one of the outstanding features of humid tropical regions
Reason (R): Intensity of chemical weathering depends to a large extent on abundance of water and higher air temperatures
Both A and R are true and A is correct explanation for R
Both A and R are true and A is not correct explanation for R.
A is true and R is false
A is false and R is true
Assertion is correct and reason is the correct explanation because chemical weathering is the breakdown of rocks through the reaction of one or more of their constituent minerals with water, other chemicals dissolved in water, or atmospheric gases. Chemical weathering intensifies in higher temperatures and presence of lot of water and therefore is most common in humid tropical regions.
8. Crickmay while disagreeing with Davis supplanted peneplain with the term:
d) Structural plain
Crickmay proposed the panplain or plain formed of floodplains joined by their own growth.
9. What is the correct sequence of the cloud types in a warm front away from its trailing edge?
(A) Altostratus – Nimbostratus - Cirrus - Cirrostratus
(B) Cirrostratus - Nimbostratus Altostratus Cirrus
(C) Cirrus – Nimbostratus - Altostratus - Cirrostratus
(D) Nimbostratus Alto Stratus Cirrostratus cirrus.
A warm front forms when a warm air mass is actively overriding a cold air mass. As warm air rises above cooler air, widespread cloudiness and precipitation develop along and in advance of the ground-level position of the front. Higher and less dense clouds are often dozens or hundreds of kilometers ahead of the ground-level position of the front.
10. Westerlies are examples of
(A) Macro atmospheric motions
(C) Microscale atmospheric motions
The largest planetary-scale wind patterns or macroscale winds, include the westerlies and trade winds. Smaller macroscale circulation is synoptic scale, or weather-map scale. Mesoscale winds include thunderstorms, tornadoes, and land and sea breezes, influence smaller areas and often exhibit intensive vertical flow. Smallest scale of air motion is the microscale like local, often chaotic, winds include gusts and dust devils.
