Option D. The mechanical layer of Earth that has the most active convection currents is Asthenosphere.
<h3>What is Asthenosphere?</h3>
The asthenosphere is the mechanically weak and ductile region of the upper mantle of Earth.
The asthenosphere, zone of Earth's mantle lying beneath the lithosphere and believed to be much hotter and more fluid than the lithosphere. It is the most active layer for convection current.
Thus, the mechanical layer of Earth that has the most active convection
currents is Asthenosphere.

The magnitude of the tangential force that acts on the pole due to the tension in rope is given as
T= weight x tan (theta) /2
When calculated energy transferred between objects use the definition of heat as
Answer:
No, because pressure is determined by force and the area over which that force acts.
Explanation:
Convergent boundaries form earthquakes, which forms mountains and islands.
