The removal of material by erosion will cause the crust to
a. subside.
b. rise.
c. subduct.
d. fold.

The removal of material by erosion will cause the crust to RISE

b. rise.

Explanation:

The removal is a process of the crust to gets eroded by the action of the geomorphic agents and that causes the crust to rise as the action of the weathering and the mass wasting have on the rocks of the planet and that the crust gets formed and deformed by the same process each and every day. Hence, the earth's crust tends to rise and the agents of biological, chemical and physical weathering operate form the above the surface. The crust gets folded and then gets bent  by the geologic process that shapes the landscape from below.  The example of the river landscape and that of the volcanic landscape and also that of the mountainous landscape.

May consider a group  g=({0,1},+)g=({0,1},+)where  ++  will work as the xor operator like we work in boolean algebra. note here, that ‘00’ and ‘11’ are not the usual 0 and 1 that we work with everyday. the elements are  called  ‘00’ and ‘11’ and  may not mean  zero (nothing) and one (single). ‘00’ is the identity for the given binary operator +, meaning that any element operated with ‘00’ gets us that element itself.  for a set  ss  in  g′g′  having more elements than just  {0,1}{0,1}  the values for  a+b∈sa+b∈s, such that  a∈s,b∈sa∈s,b∈s, have to be first defined, only then can you determine the value of  1+11+1. the answer could possibly have been  22  if oanswer is25,000

The answer is d) rift
