Options:
To identify and interpret planation surfaces
To measure soil erosion in a region
To study the evolution of flora and fauna in a region
To study the tectonic activity in a region
Option: A
What does the concept of palimpsest topography mean?
Options:
The study of the history of vegetation in a region
A surface that bears the imprints of geomorphological processes during past geological periods
The study of the formation of mountains and valleys
The process of soil erosion in a region
Option: A
What is the main objective of the denudation chronology method?
Options:
To study the evolution of flora and fauna in a region
To measure the tectonic activity in a region
To identify and interpret planation surfaces developed in past cycles and subcycles of erosion
To study the history of human settlements in a region
Option: C
What is the denudation chronology approach?
Options:
A deductive approach to understanding geomorphic history
A speculative approach to understanding geomorphic history
A method for dating erosion surfaces
A method for understanding the original forms of erosion surfaces
Option: A
What is one weakness of the denudation chronology approach?
Options:
It relies on too much evidence
It is too speculative
It is too focused on the original forms of erosion surfaces
It relies on limited information and evidence
Option: D
What are erosion surfaces?
Options:
Elevated areas of land that have been heavily eroded
Flat or near-flat surfaces formed by cycles of erosion
Areas of land that have been heavily impacted by earthquakes
Undulating ground surfaces caused by volcanic activity
Option: B
What is the significance of erosion surfaces?
Options:
They provide clues for the reconstruction of denudation chronology
They are important for understanding volcanic activity
They are useful for dating geological formations
They are critical for understanding the impact of earthquakes
Option: A
Which of the following is not an erosion surface?
Options:
Valley side benches
River terraces
Raised beaches
Structural benches
Option: D
What is the difference between erosion surfaces and structural benches?
Options:
Erosion surfaces are formed due to the removal of weak strata by denudational processes, while structural benches are structurally controlle
Erosion surfaces cut across geological formations and structures, while structural benches are parallel to the exposed underlying strata and their dip angle.
Erosion surfaces are formed due to erosion of different rock types and different geological structures, while structural benches are formed due to removal of overlying weak strata by denudational processes.
Erosion surfaces are found at higher elevations, while structural benches are found at lower elevations.
Option: B
Why is it difficult to find erosion surfaces close to present sea-level?
Options:
Because most erosion surfaces have been largely affected by tectonic movements such as uplifting, subsidence, and upwarping.
Because sea-level is not stable and has experienced several phases of positive and negative changes due to climatic changes and tectonic movement.
Becausee most erosion surfaces have been up-lifted to higher elevations.
Because erosion surfaces closer to sea-level have not yet experienced subsidence.
Option: A
Which of the following is true about sea-level?
Options:
Sea-level has remained constant throughout the geological and geomorphic history of the earth.
Sea-level is not stable and has experienced several phases of positive and negative changes due to climatic changes and tectonic movement.
Sea-level has only experienced positive changes due to glacial and interglacial ice ages.
Sea-level has only experienced negative changes due to upliftment and subsidence of coastal land and sea floor.
Option: B
What is the basis for determining whether surfaces are structural or erosional?
Options:
Aerial photography
Ground checks and field observation
Satellite imagery
Topographic maps
