a. Western ghats are lower in height than Eastern ghats
b. The height of western ghats increases from north to south
c. The highest peak in the western ghats is Doddabetta
Which of them are true?
2. Which of the following rivers flow through rift valley

b. Western coast is narrow while Eastern coast is broad
c. Western coast consists of small number of ports than eastern coast
Which of them are true?
4. Match the following
a. Karewas 1.Summer grasslands
b. Bugyals 2. Glacier deposits
c. Kayals 3. Backwaters of kerala
d. Playas 4. Dry salt lakes
5. Identify the true statements from the following ones
a. Granite and gneiss are igneous rocks
b. Schist and Shale are metamorphic rocks
1.a,b. Anamudi is the highest peak in the Western Ghats
ReplyDelete2. narmada and tapi
3.all
4?
5.both
3 answer correction.only a and b
Delete1) a. Western Ghats are higher than eastern ghats
ReplyDeleteb. Correct
c. Abhishek got it correctly. Anamudi, not Dodabetta, is the heighest peak
2)Narmad and Tapi flow through rift valley. This is imp bit. Also read more about the rift valley and how it has formed in India
3) Western coast is submerging not emerging. So it has narrow coast and many ports are there
4)This is very imp bit;
Karewas=Glacier deposits
Bugyals = Summer grass lands used by Bhotias for their sheeps (also read abt transmuhance in this context)
kayals=Back waters of kerala
playas=dry salt lakes
5) Shale is a fine-grained, clastic sedimentary rock composed of mud that is a mix of flakes of clay minerals and tiny fragments of other minerals, especially quartz and calcite. The ratio of clay to other minerals is variable. Shale can metamorphose into slate, phyllite, schist or gneiss depending on the degree of heat and pressure
So shale=sedimentary rock
Schist and Gneiss=metamorphic rocks
Granite=igneous rock
