Two blocks of ice when pressed together join to form one block because
  1. of heat produced during pressing
  2. of cold produced during pressing
  3. melting point of ice decreases with increase of pressure
  4. melting point of ice increases with increase in pressure

Solution

When two blocks of ice are pressed against each other, then the pressure applied on the blocks of ice increases and the melting point decreases. Thus, two blocks of ice fuse together and form one block.
