A.) Why do the researchers want to look for an impact crater in the area where the glass is found? Please elaborate on your answer.

Libyan Desert Glass is the world's purest naturally created silica glass which is found only in a part of the Sahara Desert, 

which made scientists think that a meteor strike produced it.  

A meteor strike could be either an airburst or a ground impact.

Scientists had thought that the Libyan Glass would be produced by an airburst before they found a structure named zirconia within the glass.

Zirconia is said to be created with high temperature which means that the glass would be produced by a ground impact. 

That would be why scientists want to find an impact crater that could prove the ground impact. ✔​
