The characteristics of two layers of earth’s crust are listed. layer a: hard, rigid outermost layer of earth layer b: "plastic" layer containing the mesosphere which statement is true? layer a is the crust and layer b is the mantle. layer a is the mantle and layer b is the crust. layer a is the outer core and layer b is the inner core. layer a is the inner core and layer b is the outer core.

Layer A is the crust and Layer B is the mantle.

Explanation:

The crust is the hardest and hardest layer on earth. It is an external and solid layer, consisting mainly of rocks, soils and a variety of minerals. It can be classified as terrestrial crust, or oceanic crust (when it is below the ocean).

The Mantle, in turn, is located just below the crust and has a more plastic consistency, being a less rigid layer than the crust. The mantle extends to almost half the earth's radius and its apparent "plasticity" is the result of magma.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a

c.           is the correct answer
