In this assignment, we will investigate where current earthquakes are today, from a ground-sensed motion. Search for: Introduction to Tectonic Forces. Physical Geography Lab Manual by R.

Faults are subdivided according to the movement of the two blocks. Top 15 Most Expensive Gemstones In The World, Scientists discover fault system in southeastern Nepal, Chance of big San Andreas earthquake increased by Ridgecrest temblors, study suggests. Faults allow the blocks to move relative to each other. Normal Fault.

A convergent boundary is when two plates collide.

Compare the characteristics and spatial distribution of lithospheric systems (i.e., plate tectonics, earthquakes and volcanoes, weathering, mass movement, river systems, and landforms). Search for: Causes and Types of Tectonic Stress. Faults are subdivided according to the movement of the two blocks. Tensional stress occurs when a rock is subjected to forces that tend to elongate it or pull it apart; a rock that has experienced tensional stress tends to be narrower and longer than its original shape, like a piece of gum or taffy that has been pulled. If you were to stand on the fault and look along its length, this is a type of strike-slip fault where the right block moves toward you and the left block moves away. Divergent occurs when two tectonic plates move away from the other. We will then analyze how properties of volcanoes are influenced by the crust and tectonic plate boundaries nearest them.
