In the ocean how does water temperature change as depth increases
tatuchka [14]
When the upper water layers warm in the summer months, they become separated from deep water by a transition zone known as a thermocline. In a thermocline, the temperature decreases rapidly with small increases in depth. This phenomenon linking temperature change with depth is called temperature stratification.

The cerebellum plays a major role in the control and coordination of all physical movements such as balance, control, etc, that has to deal with smooth and balanced activities of the muscle.  

A damage to the cerebellum would most likely lead to impaired motor coordination, staggering, inability to judge distance or when to stop.

Describe the route of a reflex impulse in the somatic system
Sholpan [36]
Take for example - you touching something sharp and instantly moving your hand away.

Sensory neurons in your fingers detect the external stimuli of the sharp object and send a nerve impulse to the spinal cord (does not reach brain) and is sent back to a motor neurone - attached to an effector that moves the muscle and moves the hand away. This is a rapid reflex action and involuntary.
