Please I want someone to answer these questions with short answers

1. Know the difference between bulk modulus and shear modulus. 2. Know the difference between compositional boundaries and mechanical boundaries. COMPOSITIONAL LAYERS MECHANICAL LAYERS continental crust (10-70 km lithosphere 10-200 km oest oceanic crust S-7 km) mantle mesosphere outer core core inner core 2900 m 396 km 5150km 660 om https://www.visionlearning.com/en/library/Earth-Science/6/Earth-Structure/69 3. Know where the discontinuities are located (Moho, Gutenberg, Lehmann, and Conrad

Explanation / Answer

1) Bulk modulus is defined as the ratio of   pressure change to the fractional volume of compression .

Bulk modulus = (Change in pressure/ Fractional volume of compression )

Unit of Bulk modulus is Pa.

Shear modulus is defined as the ratio of shear stress to the shear strain.

Shear modulus = Shear stress/ Shear strain

Unit of  Shear modulus is pascal (Pa)
