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 how the body moves by sending out small electrical signals through the nerves to the muscles. Seizures, or convulsions, occur when abnormal signals from the brain change the way the body functions. Seizures are different from person to person.
