a.
To identify:
The mid-ocean ridge whose rate of plate motion is faster.
Introduction:
Earth is made up of four layers, namely, crust, mantle, outer core, and inner core. The crust is rocky and made up of big rocks. The mantle is made up of smaller rocks and is arranged in the form of plates. The core is the hottest region and consists of magma.
b.
To describe:
The reason behind the thickness of the mid-ocean ridge.
Introduction:
The tectonic plates, also called the lithosphere, are a mixture of the crust and the outer mantle. Such plates are moving very slowly, only a few inches a year. A fault is where the plates strike each other. When the plates shift and the boundaries collide with each other, an earthquake may occur
