1 The concept of bowl Tectonics:

*

2 The Lithosphere is broken into different sections dubbed plates. The key fit with each other along crack in the lithosphere.

*

3 Canadian scientist, J. Tuzo Wilson, linked what geologists knew around sea-floor spreading, earth plates, and also continental drift in come a single scientific theory. A clinical theory is a well-tested principle that explains a wide range of observations.

*

4 theory of key Tectonics: The concept of plate tectonics claims that pieces of earth’s lithosphere space in slow, consistent motion, pushed by convection currents in the mantle. The concept of bowl tectonics explains the formation, movement, and subduction of earth plates.

*

5 Geologists think the activity of convection currents in the mantle is the major force that causes the activity of the plates. Together the plates move, they collide, pull apart, or grind past each other, creating spectacular changes in Earth’s surface ar These changes include volcanoes, hill ranges, and deep-ocean trenches.

*

6 Faults Faults space breaks in earth crust where rocks have slipped previous each other. They type along different varieties of boundaries. There are three varieties of key boundaries: divergent boundaries, convergent boundaries, and also transform boundaries. A different kind of plate motion occurs follow me each kind of boundary.

*

7 Divergent borders The place where two plates move apart (or diverge) is referred to as a divergent boundary. Many divergent limits occur follow me the mid-ocean ridges wherein sea-floor dispersing occurs.

*

8 And… Divergent boundaries also occur ~ above land. This is as soon as two of earth’s plates on slide apart. A deep valley referred to as a rift valley forms along the divergent boundary.

*

9 Convergent Boundaries: The ar where two plates come together (or converge) are called convergent boundaries. As soon as two bowl converge, the an outcome is referred to as a collision. As soon as the 2 plates converge, the density chose which bowl comes the end on top. This usually create mighty mountains.

*

10 change Boundaries: A transform border is a place where 2 plates slip previous each other, moving in the contrary directions.

Earthquakes regularly occur follow me transform boundaries, yet crust is neither produced or destroyed.
