The theory of plate tectonics proposes that the earth’s lithosphere is divided into ______ major and some minor plates.

Correct option is A

Correct Answer: (A) 7

Explanation:
The theory of plate tectonics suggests that the Earth's lithosphere (the outermost layer of the Earth) is divided into seven major tectonic plates, along with some smaller, minor plates. These major plates include the Pacific Plate, North American Plate, Eurasian Plate, African Plate, Antarctic Plate, Australian Plate, and the South American Plate. The movement of these plates is responsible for many geological phenomena such as earthquakes, volcanic activity, and mountain formation.

Information Booster:

● Tectonic plates: Large, rigid pieces of Earth's lithosphere that move over the semi-fluid asthenosphere beneath them.
● Major plates: Seven key plates (e.g., Pacific, North American, Eurasian, etc.) that cover the majority of the Earth's surface.
● Minor plates: Smaller plates like the Juan de Fuca Plate and the Cocos Plate.
● Plate boundaries: Plates interact at boundaries, causing geological events such as earthquakes and volcanic eruptions.
● Convection currents: The movement of the Earth's plates is driven by convection currents in the mantle beneath them.
