Question

The Earth's _______ is ductile overall, tending to flow very slowly and deform in a _______ manner.

Answer 1

The asthenosphere is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement and isostatic adjustments. The lithosphere-asthenosphere boundary is conventionally taken at the 1300 °C isotherm, above which the mantle behaves in a rigid fashion and below which it behaves in a ductile fashion. and flows very slowly, in a manner similar to the ice at a bottom of a glacier.

Answer 2

Answer:

The answer is "lithosphere and brittle"

Explanation:

The word lithosphere is the outermost crust of the earth, which consists of the roast of the planet and the rest of the fur. The tectonic plate, which is also known as the asthenosphere, has fractured mostly.  

The substance brittles when under tension, separates without significant plastic deformations and behaves like a ductile, a shape acting to move very slowly, like the ice at the foot of a glacier.
