ch 5- changing the crust
DESCRIPTION
Ch 5- Changing the Crust. The rising and falling of the lithosphere into the asthenosphere due to changes in weight are called isostatic adjustments. These movements cause stress on the crustal rocks. Many times the rocks will fold without breaking; 3 ways. 1. Anticline. 2. Syncline. - PowerPoint PPT PresentationTRANSCRIPT

These movements cause stress on the crustal rocks

Many times the rocks will fold without breaking; 3 ways
1. Anticline
![Page 6: Ch 5- Changing the Crust](https://reader035.vdocuments.us/reader035/viewer/2022062520/568165b5550346895dd8b20f/html5/thumbnails/6.jpg)
2. Syncline
![Page 7: Ch 5- Changing the Crust](https://reader035.vdocuments.us/reader035/viewer/2022062520/568165b5550346895dd8b20f/html5/thumbnails/7.jpg)
3. Monocline

Other times the rock will break; if the rocks do not move it is called a fracture
If the rocks move, it is called faulting

Constant changing of the crust forms mountains and valleys

Types of mountains
1. Folded mountains
