Answer Strengths Gaps Keywords

Main Body

Earth crust is mainly composed of igneous, sedimentary and metamorphic rockstructure

Types of rocks:

1[Igneous rocks]

Nature:

Undifferentiable and high density

Low void gas in crystals

Lack any fossils evidence

Origin:

Resting of hot volcano lava and solidification is on over ground

2[Metamorphic rocks] are recrystallized rock structures may have platine impregnate exfoliated over usually denoted time shorten for layers

3[Sedimentary rocks structure]

Nature: + Fossiliferous

Contain oil and natural gas

weak rock shoring

void in crystal structure

Origin: Solidification lithification of sediments dist rock under pressure and temperature. There is courteous exchange between these different rock structure erupting the cyclicity and dynamic nature

[Pressure] + [temperature] ⇒ recrystallise origin rock structure

3Sedimentary rock structure:

Nature + Fossiliferous

contain oil and natural gas

weak rock shoring

void in crystal structure

Origin - Solidification lithification of sediments dist rock under pressure and temperature.

There is courteous exchange between these different rock structure erupting the cyclicity and dynamic nature

Modern lifestyle of urbanized materialism and consumerism linked with growth of urban cities and digital era is dear demarcation of shift away from nature.

Modern lifestyle contributing environment crisis

1clearing of forest and for urban or human settlement (eg) Newt Hydrabad forest land clearance care

2water crisis (1450 cum) pump due to high wastage and direct discharge - only 60% treated with in city

3vulnerability of landfills and floods (eg) Uttarkashi cloud burst and induced damage

4rising sea level due to global warming and GHG emision

3cow emision toppled in blue industrial revolution

5immense in urbanization (2) encroachment of flood plains in China

wasting and GHG emision

2CO2 emision toppled in blue industrial revolution

5immense in urbanization (2) encroachment of flood plain in China

Modern lifestyle alone is alone not responsible

1India perceive GHG emission of 7% borne on Litthem global avg of 4.2 ore

2increased greenfield in India - 2025 ISFR report 2.8% forest cover

1changing [mitigating environmental]

offset

1missing (2) curbing capacity (3) adopting techniques (3) Miyawaki forest

studies under lifestyle and issues faced solution sided in indian roots. Both adoption and mitigation are pathways to improve SDG 13 in the spirit.
