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.
In humans, the brain also controls our use of language, and is capable of abstract thought. The brain is the control centre of the whole body. The brain is made up of a special type of cells.They are connected with each other and with the nerves in our body.he brain stem is at the back of the brain (actually underneath it in humans). It joins the rest of the brain with the spinal cord. It has lots of different parts that control different jobs in the body: for instance, the brain stem controls breathing, heartbeat, sneezing, eye blinking, and swallowing.
The human brain is a complex organ controlling every voluntary and involuntary action we make. The brain controls basic motor skills, heart and breathing rates, emotions, behavior and decision-making. There is a part of the brain responsible for addiction. The name for this part of the brain is the limbic system. This system, also known as the âbrain reward system,â is responsible for producing feelings of pleasure.
