Snow and ice in the high latitudes generally do not melt even during the summer monthsâthey accumulate over time. Layers of snow fall and are covered by subsequent layers. As layers of snow accrue, their vertical thickness increases, and the snow transforms into ice as the air is squeezed out.
The brain is one of the most complex and magnificent organs in the human body. Our brain gives us awareness of ourselves and of our environment, processing a constant stream of sensory data. It controls our muscle movements, the secretions of our glands, and even our breathing and internal temperature.Every creative thought, feeling, and plan is developed by our brain.ur brain gives us awareness of ourselves and of our environment, processing a constant stream of sensory data.

The brain controls and coordinates most sensory systems, movement, behavior, and homeostatic body functions such as heart rate, blood pressure, fluid balance, and body temperature. The brain is the source of cognition, emotion, memory, and motor, and other forms of learning.arly views on the function of the brain regarded it as little more than cranial stuffing. In Ancient Egypt, from the late Middle Kingdom onwards, in preparation for mummification, the brain was regularly removed, for it was the heart that was assumed to be the seat of intelligence.
