ii. Till is an example of fine sand carried by wind.
a. I only
b. ii only
c. both
d. none
View Answer / Hide AnswerANSWER: d. none
Sediments are carried away by various elements like water, wind or ice etc. Loess is an example of a wind-borne sedimentary rock and till which is an unsorted mixture of clay and boulders is an ice deposited sedimentary rock.
a. hardness
b. closely banded
c. interlocking of crystals
d. all the above
View Answer / Hide AnswerANSWER: d. all the above
Metamorphic rock as the name suggests involves change. This process takes place under the pressure of the rocks as a result of its contact with some hot igneous material.
i. The formation of metamorphic rocks due to pressure is called contact metamorphism.
ii. The formation of a metamorphic rock as a result of high temperature is called thermal metamorphism.
a. I only
b. ii only
c. both
d. none
View Answer / Hide AnswerANSWER: b. ii only
The formation of metamorphic rock due to the stress of pressure is called as dynamic metamorphism. Thermal metamorphism is also known as contact metamorphism and results in the formation of a metamorphic rock due to the high temperature in the earth's crust.
i. Granite is converted into gneiss under thermal metamorphism.
ii. Sandstone changes into quartzite under dynamic metamorphism.
a. I only
b. ii only
c. both
d. none
View Answer / Hide AnswerANSWER: d. none
Under dynamic metamorphism which is a result of excess pressure, granite is converted into gneiss. In the thermal metamorphism which is a result of high temperature, sandstone changes into quartzite.
i. Clay and shale are transformed into slate under thermal metamorphism.
ii. Clay and shale are transformed into schist at contact metamorphism.
a. I only
b. ii only
c. both
d. none
View Answer / Hide AnswerANSWER: a. I only
Clay and shale are transformed into slate under thermal metamorphism which is also known as contact metamorphism. clay and shale are transformed into schist inter dynamic metamorphism.
a. Piedmont plateaus
b. Continental plateaus
c. Lava plateaus
d. Intermontane plateaus
View Answer / Hide AnswerANSWER: b. Continental plateaus
Continental plateaus are formed as a result of an abrupt rise of a plateau from a lowland or a sea. They are the resultant of a continental uplift. Example for this is the Karnataka and Ranchi plateau in India.
a. Piedmont plateaus
b. Continental plateaus
c. Lava plateaus
d. Intermontane plateaus
View Answer / Hide AnswerANSWER: d. Intermontane plateaus
Intermontane plateaus are enclosed with the mountains either fully or partly. The best example for this type of plateaus is the Tibetan plateau which is enclosed by the mountains.
a. Piedmont plateaus
b. Continental plateaus
c. Lava plateaus
d. Intermontane plateaus
View Answer / Hide AnswerANSWER: a. Piedmont plateaus
Piedmont plateaus are situated at the foot of the mountains. Also, they are bounded by a plain or an ocean on the opposite side. The best example of such a plateau is the Malwa plateau in India.
a. fan-shaped delta
b. bird-foot data
c. arcuate delta
d. cuspate delta
View Answer / Hide AnswerANSWER: b. bird-foot data
When the river water is as dense as the sea water, it is called a lobate or fan-shaped data. delta refers to the deposition which is mostly a triangular shaped. Sundarban is the largest delta in the World.
1. arcuate delta ------------- A. Indus
2. Estuarine delta ----------- B. Narmada
3. Cuspate delta ------------- C. Ebro
4. Bird-foot delta ----------- D. Mississippi
a. 1A, 2B,3C,4D
b. 1A, 2C,3B,4D
c. 1C, 2A,3D,4C
d. 1D, 2C,3B,4A
View Answer / Hide AnswerANSWER: a. 1A, 2B, 3C, 4D
The other examples of an arcuate delta are the Nile, Ganga, Rhine, Niger, Irrawaddy, Volga, Danube, Mekong etc and river Omo is also an example of a bird-foot delta. Rivers Tapi, Amazon, Mackenzie, Vistuala, Elb etc are examples of estuarine deltas.
