Folds and Faults Mountains are regions of disturbed or deformed rocks. Stresses in the Earths Crust; 2 Stress can be Compressional, Tensional, or Shear Compressional stress pushes matter (rock layers) together Tensional stress pulls matter (rock and dirt layers) apart. A fault line is the trace of a fault, or the line of intersection between the fault line and the earth's surface. The activities and discussion questions in the slideshow are meaningful.

The dominant displacement on these faults is horizontal and parallel to the strike of the fault’s surface. Also included are critical class notes (color coded red), project ideas, video links, and review games. yes, but the link between Faulting occurs when rocks fracture under the accumulation of extreme stress created by … This unit aligns with the Next Generation Science Standards and with Common Core Standards for ELA and Literacy for Science and Technical Subjects. TYPES OF FOLDS . Sedimentary rocks are more flexible than the metamorphic, and when the thrust is not intense enough to move them fold as if they were a piece of paper.A fold is a bending o… 1.

An oblique slip involves various combinations of these basic movements, as in the 1855 Wairarapa Fault rupture, which included both reverse and dextral movement. The folds arise as a result of the tectonic pressure and stress in the rocks and rather than fracture, they fold. They are differentiated into three types according to the nature of the deformation which created them: 1. dome mountains result from the upward bending of rocks into the form of a dome. Looks like you’ve clipped this slide to already. 4. When the layers of rock in the Earth's crust fold, the land’s surface is pushed up as hills or mountains.This process is called orogeny.

Sliding plates and drifting continents are responsible for some of the Earth’s major landscape features. The line it makes on the Earth's surface is the fault trace. Well . Folds are (undulations or corrugations) expression of plastic type of deformation which produce more gradual but more continuous change in rock. Fold, in geology, undulation in stratified rocks.

These types of folds can be created by the reactivation of faults or the emplacement of migrating salt structures (Fossen 2016). "reverse fault", "anticline" (1)• Quality of diagram/description (2)• Reference to appropriate scale (1)• Specific location of feature (1)• Correct name of stress involved (1) R• e.g. Since folds are permanent deformation structures with no or little loss of cohesion of the folded layer, folding refers to the essentially slow, ductile behaviour of relatively soft and/or hot rocks.
