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.
What Does the Brain Do? The brain is the control centre for all the bodyâs functions, such as walking, talking, swallowing, breathing, taste, smell, heart rate and so on.t also controls all our thinking functions, our emotions, how we behave and all our intellectual (cognitive) activities, such as how we attend to things, how we perceive and understand our world and its physical surroundings, how we learn and remember and so on.
