Salinity measures the amount of dissolved minerals in seawater.
Answer:
Option (A)
Explanation:
The lithosphere represents the rigid outer shell of the Earth, exhibiting brittleness that leads to the fracture of rocks upon deformation. It comprises numerous tectonic plates categorized into two types: the oceanic and continental crusts.
These plates float atop the less dense asthenosphere due to convection currents generated within the mantle. The heat from the Earth's interior causes this current. The movement of plates across the asthenosphere is known as the theory of plate tectonics. Therefore, the correct selection is option (A).
