What is the steep rocky coast rising almost vertically above sea water called?
-
Sea Cliff.
|
| 3352 |
What is the term for the acquisition and transportation of rock debris or soil?
-
Erosion.
|
| 3353 |
What is the most important agent of erosion?
-
Water.
|
| 3354 |
What is the most important force of erosion?
-
Gravity.
|
| 3355 |
What is the main difference between weathering and erosion?
-
No movement is involved in weathering, while erosion involves moving particles from one place to another.
|
| 3356 |
What is the significance of weathering?
-
Breaking down rocks into smaller fragments, preparing the way for the formation of regolith and soils, erosion, and mass movements.
|
| 3357 |
What are the three major groups of weathering processes?
-
Chemical, physical or mechanical, and biological weathering.
|
| 3358 |
What is of particular importance in conditioning weathering processes?
-
Climate.
|
| 3359 |
What is Weathering defined as?
-
Mechanical disintegration and chemical decomposition of rocks through the actions of various elements of weather and climate.
|
| 3360 |
Which processes are included in Denudation?
-
Weathering, mass wasting/movements, erosion, and transportation.
|
| 3361 |
What is the general term for all exogenic geomorphic processes?
-
Denudation.
|
| 3362 |
What is a fracture of large magnitude in the crustal surface with displacement parallel to the plane of break called?
-
Fault.
|
| 3363 |
What are the lows/troughs/downfolds of folded rock strata called?
-
Synclines.
|
| 3364 |
What are the highs/crests/upfolds of folded rock strata called?
-
Anticline.
|
| 3365 |
What is the bending of the rock strata due to compression tangential forces called?
-
Folding.
|
| 3366 |
What are the two main classifications of Diastrophism?
-
Epeirogenic (vertical movement) and Orogenic (horizontal/tangential movement).
|
| 3367 |
What does Diastrophism refer to?
-
Deformation of the Earth's crust, and more especially to folding and faulting.
|
| 3368 |
What are the two main endogenic processes?
-
Volcanism and Diastrophism.
|
| 3369 |

-
From 40 million years ago and thereafter.
|
| 3370 |
What major event occurred during the movement of the Indian plate towards the Asiatic plate around 60 million years ago?
-
Outpouring of lava and formation of the Deccan Traps.
|
| 3371 |
What is the approximate speed of plate movement?
-
1 to 10 cm/year.
|
| 3372 |
What happens at a Transforming Boundary?
-
Plates pass by each other without creating or destroying the crust.
|
| 3373 |
What type of plate boundary is also known as a Conservative Boundary?
-
Transforming Boundaries.
|
| 3374 |
What forms at Continent-Continent convergence?
-
Fold mountains (e.g., Himalayas).
|
| 3375 |
What forms at Ocean-Continent convergence?
-
Fold mountains on the continental crust and trenches on the oceanic side.
