PROBLEM: Question: Derek is diving into the ocean. The pressure at the surface will be light, and the pressure the shallower he goes will be 
 Option1: stronger 
 Option2: weaker 
 Explanation: Pressure: Pressure increases with depth, but increased pressure raises the melting temperature, so melting of rock is less likely to occur at higher pressures.

SOLUTION: weaker

PROBLEM: Question: Mike wants his voice to travel slowly, so he will speak in a room that is 
 Option1: colder

 Option2: less likely to become a fossil?

SOLUTION:
less likely to become a fossil?
