EARTHQUAKES

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The distribution of earthquakes on Earth’s surface is evidence that Earth’s crust is divided into ____
A
dishes
B
oceans
C
plates
D
mantle
Explanation: 

Detailed explanation-1: -The upper layer of the earth’s surface, the mantle and the crust are divided into tiny pieces known as tectonic plates. The boundaries of these tectonic plates made up of several faults are where most earthquakes occur.

Detailed explanation-2: -Evidence for the theory of plate tectonics is continental drift, appearance of younger crustal layers in the ocean, earthquakes along plate boundaries called fault lines, the presence of similar fossils and rocks on separate continents, and the matching shapes of continents that once fit together as a larger continent.

Detailed explanation-3: -The Earth is broken into plates to allow recycling materials amid the crust and the mantle. Earth crust and the top part of the mantle are broken into enormous pieces known as tectonic plates. These plates are in motion, giving the planet a chance to shift several miles apart through continental drift.

Detailed explanation-4: -Earthquakes occur along fault lines, cracks in Earth’s crust where tectonic plates meet. They occur where plates are subducting, spreading, slipping, or colliding. As the plates grind together, they get stuck and pressure builds up. Finally, the pressure between the plates is so great that they break loose.

Detailed explanation-5: -In plate tectonics, Earth’s outermost layer, or lithosphere-made up of the crust and upper mantle-is broken into large rocky plates. These plates lie on top of a partially molten layer of rock called the asthenosphere.
