Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is Geotechnical engineering known for?Development of principles like effective stress and consolidation theory by Karl Terzaghi
2. What is the core disciplines?Soil mechanics and rock mechanics, integrated with geology and geophysics
3. What is the primary applications?Foundation engineering, slope stability analysis, tunnel design, offshore construction, and infrastructure development
4. How do engineers test the ground before building?Engineers use tests like the Standard Penetration Test and Cone Penetration Test right in the ground, and they also bring soil samples to a lab to measure strength, density, and how water moves through it.
5. Why is geotechnical engineering important for big buildings and bridges?Knowing how the ground will react to loads, water, and earthquakes helps engineers design foundations that keep structures stable and safe.

Soil Mechanics: The study of the mechanical behavior of soil under stress and strain, crucial for foundation design and stability analysis.
Rock Mechanics: The study of the mechanical behavior of rock masses, essential for tunnel excavation and underground construction.
Effective Stress: The stress carried by the soil skeleton, calculated as total stress minus pore water pressure, a fundamental concept in soil mechanics.
