The Earth’s plate responsible for causing earthquakes is a) the crust of the Earth.
Explanation: Earthquakes are caused by the movement of tectonic plates, which are sections of the Earth’s crust that float on the mantle.
Key points about the other options:
b) the mantle of the earth:
While the mantle plays a role in plate movement due to convection currents, it is not the direct cause of earthquakes.
c) the inner core of the earth:
The inner core is solid and deep within the Earth, making it not involved in plate tectonics.
d) the outer core of the earth:
The outer core is liquid and also not directly involved in plate tectonics.
