The warm ocean water is usually found near the top surface of the ocean. The sun makes the surface of the ocean warm and thus heat up its water. This heat is later mixed by the winds and sea waves from top to beneath the ocean surface. The temperature of the surface is usually warmer than the water at depths as it does not receive sun light. The average ocean temperature at the surface is 17 degree Celsius while at greater depth the temperature falls down to 0 to (-3) degree Celsius
The cerebral cortex of the brain has four paired lobes.
one of these four paired lobes is the frontal lobe and it occupies 2/3rds of the entire human brain.
the frontal lobe is associated with performing tasks such as speech and language production, walking and running, classifying and identifying objects, reacting to feelings, forming memories, forming the personality of a person, and attention involving tasks.
Since after the injury, Zack has an altered personality and his reaction to the situation has changed, this points out to the fact that he is most likely suffering from frontal lobe injury.
The particle size is important because the more finely divided the solid is , the faster the reaction happen. A powdered solid will normally produce a faster reaction because it has greater surface area than the single lump
