This layer of the Earth is divided into tectonic plates A. Lithosphere B. Ionosphere C. Mesosphere D. Athenosphere

The correct answer is:<br /><br />A. Lithosphere<br /><br />The lithosphere is the outermost layer of the Earth and is divided into tectonic plates. These plates float on the semi-fluid asthenosphere beneath them, which allows them to move and interact with each other, leading to geological activities such as earthquakes and volcanic eruptions.
