PPT-Deforming the Earth’s Crust

Deformation Whether a material bends or breaks depends on h ow much stress is applied to the material Deformation Process by which the shape of a rock changes because of stress Objectives Describe. 1 Energy in Deforming Materials energy kinetic energies potential energies elastic strain energy inside work permanent plasticity theory all principle of work and kinetic energy principle of conservation of mechanical Isostasy.

What are anticlines?. UNIT 1. What is Geology. Geology is the study of Earth, including the materials that it is made of, the physical and chemical changes that take place on its surface and in its interior and the history of the planet and its life form. Presented by Kesler Science. What are the main characteristics of the Earth’s layers?. How can the Earth’s layers be illustrated?. Essential Questions:. Earth's Layers. Earth’s Crust.
