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 tectonic setting?Predominantly found in compressional regimes at convergent plate boundaries
2. What is the associated structures?Imbricate thrust stacks, duplexes, recumbent folds, klippen, and foreland basins
3. Why do rocks move like skiing on a thrust fault?Big pushes from colliding plates make the crust squeeze and slide, letting the upper rock layer glide over the lower one.
4. How do thrust faults build mountains?When many rock layers stack on top of each other, the crust gets thicker and pushes up, forming tall mountain ranges like the Himalayas.

Convergent Plate Boundary: An area where tectonic plates move towards each other, often resulting in subduction or continental collision.
Orogenesis: The process of mountain formation, especially by folding and faulting of the Earth's crust.
Décollement: A detachment surface or horizon along which large-scale rock units have moved.
Isostatic Uplift: The vertical movement of the Earth's crust due to changes in load, such as the removal of ice sheets or the addition of mountains.
