GEOLOGY

Detailed explanation-1: -Answer: Sudden movements of the earth cause a tremble in the earth’s surface which is caused by the sudden dislocation or movement of tectonic plates within the surface of the earth. These movements are commonly known as earthquakes. Earthquakes are measured on a Richter scale.

Detailed explanation-2: -An earthquake is a sudden movement of the Earth, caused by the abrupt release of strain that has accumulated over a long time. For hundreds of millions of years, the forces of plate tectonics have shaped the Earth as the huge plates that form the Earth’s surface slowly move over, under, and past each other.

Detailed explanation-3: -Complete answer: Volcanic activity is one of the sudden movements of the earth’s crust caused by the convergence or divergence of the tectonic plates.

Detailed explanation-4: -About 80% of earthquakes occur where plates are pushed together, called convergent boundaries. Another form of convergent boundary is a collision where two continental plates meet head-on. Since neither plate is stronger than the other, they crumple and are pushed up.

Detailed explanation-5: -While most earthquakes are caused by the slipping of tectonic plates, minor earthquakes can also be caused by volcanic eruptions, collapse of rock formations on Earth’s surface, or underground explosions.
