What is the importance of stratification to civil engineering? state 5 importance of stratification

Importance of stratification to Civil engineering are as follows:
- Provide an understanding of the nature of the ground
- Ensure properly structured site investigation
- Ease for assessing the permeability of composite soil
- To be able to know physical characteristics of soil/rock underlying the site
- Assess mechanical properties (i.e. strength, compressibility, etc.) of different rock strata

Pressure and heat that's what i think( don't report if wrong)

The earth's inner core is the earth's innermost part. it is primarily a solid ball with a radius of about 1,220 km (760 miles), which is about 70% of the moon's radius.[1][2] it is composed of an iron–nickel alloy and some light elements. the temperature at the inner core's surface is approximately 5,700 k (5,430 °c), which is about the temperature at the surface of the sun.
