Q: Question: Mary melts a 1 pound chocolate bar and 1 pound of chocolate chips in two pots. Which melts first? 
 Answer: chips

A: It would be hard to get a big chunk of chocolate to dissolve in your milk or hot water. Maybe you could make hot chocolate from some smaller pieces like chocolate chips, but it is much easier to add a powder to your milk. This is because the smaller the pieces are, the more surface area they have.

Q: Question: Derek is diving into the ocean. The pressure at the surface will be light, and the pressure the deeper he goes will be 
 Answer: stronger

A: Pressure: Pressure increases with depth, but increased pressure raises the melting temperature, so melting of rock is less likely to occur at higher pressures.

Q: Question: Jim is comparing two rivers. One has a steep slope and one has a shallow slope. Will the shallow slope or the steep slope provide less water availability? 
 Answer: steep slope

A:
A gentle slope favours slower flow of surface water, reduces erosion, and increases availability of water to plants.
