What is one of the Earth's interior concentric zones?
A) the asthenosphere
B) the crust
C) the ionosphere
D) the biosphere
Asthenosphere
A region of the Earth's mantle beneath the lithosphere that is mechanically weak and partially molten, facilitating tectonic plate movement.
Ionosphere
A layer of the Earth's atmosphere that is ionized by solar and cosmic radiation, playing an essential role in atmospheric electricity and forming the inner edge of the magnetosphere.
Biosphere
The global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, hydrosphere, and atmosphere.

Final Answer :
A
Explanation :
The asthenosphere is one of the Earth's interior concentric zones, located beneath the lithosphere (the rigid outer layer of the Earth). It is a soft, weak layer of the mantle that allows for the movement of tectonic plates. The other options, B) the crust, C) the ionosphere, and D) the biosphere, are all parts of the Earth's outermost layers, but not interior concentric zones.
