Which plate boundary is conservative?
Geologytransform plate margintransform plate margin, occurs where plates slide past each other in opposite directions, or in the same direction but at different speeds. Friction is eventually overcome and the plates slip past in a sudden movement. Where are conservative plate boundaries? A good example of a conservative plate margin is the San Andreas Fault

Who made the first clear statement of the law of superposition when?
GeologyIn 1669 Nicolaus Steno made the first clear statement that strata (layered rocks) show sequential changes, that is, that rocks have histories. From his work in the mountains of western Italy, Steno realized that the principle of superposition in stratified (layered) rocks was the key to linking time to rocks. When did Steno proposed the

How do volcanoes create landforms?
GeologyHow can volcanoes create landforms? The viscosity of the lava that erupts from a volcano can lead to the creation of different volcanic landforms. … This thin and runny lava can disperse over large areas, and as the lava cools and solidifies, it forms the large, flat plateaus of rock. What landforms were created by
