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 the scope of application?Foundations, earthworks, infrastructure (bridges, tunnels, rail), environmental site assessments, hazard mitigation
2. What is the emerging trends?Integration of geophysics, probabilistic analysis, BIM, and sustainable investigation practices
3. Why do engineers do geotechnical investigations before building?They want to know how strong the ground is, how it might settle, and how it reacts to earthquakes, so the building stays safe.
4. How do engineers find out what’s underground?They use surface maps, remote sensing, and drilling tools like hand augers, Shelby tubes, and core barrels to collect soil and rock samples.

Stratigraphy: The study of rock layers and their sequence, crucial for understanding subsurface composition.
In situ tests: Tests performed directly on the soil or rock in its natural location to measure properties.
Geophysical methods: Techniques using physical principles (like sound waves or electricity) to study subsurface conditions without direct excavation.
