Open scan (p.33)

Introduction

Isostasy refus to lithospheric plate arrangement to maintain altitude of landman a wells stability of them

16 words

Main Body

Isostasy maintain height-density equilibrium in differing major landforms.

Role in shaping major landforms:

1Maintain stability by equivalent map of landforms
2Creation of mountain ranges (eg) Himalayan ore region have.
3Provide stability to landforms (eg) plateaus sit on stable prods to provide stability.
4formation of land subsidence majors (2) western ghats and subsidy coast is result of isostasy disbalance
16Challenges to isostasy and equilibrium - of are mining and exhalation of minerals

(II) formation of dam and water reservoir charging network

(III) anthropogenic activities altering

Challenges to isostasy and equilibrium:

16Mining and exhalation of minerals

(II) formation of dam and water reservoir charging network

(iii) anthropogenic activities altering the natural shape of landforms.

(i) global warming and glacial melting in antentic mayland to large scale shift in isostasy equilibrium

(v) earthquake vulnerability shifting fold and joints in earth.

Conclusion: Isostasy is the nature balance of earth to provide stability of different landforms and its understanding is necessary to data understand the geology behind formation of landforms.
