Explain what can cause rock layers to be offset:

This can happen when a river or stream erodes a portion of the rock layers. This can also happen when faulting occurs. Faulting causes displacement in rock units. The figure here shows the offset between the layers signified by the black line cutting across the rocks.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.

the answer is symmetrical : )
