The cerebellar hemispheres are separated by a worm-shaped band of cortex called the: <u>Vermis</u>.
The vertebrate brain (cerebrum) is formed by two cerebral hemispheres separated by sulci and longitudinal clefts. Therefore, we can say that the brain is divided into left and right hemispheres. Each of these hemispheres has an outer layer of gray matter called the cerebral cortex supported by an inner layer of white matter. In EU (placental) mammals, the hemispheres are connected by a very large bundle of nerve fibers, the corpus callosum.
Smaller commissures, including anterior commissures, posterior commissures, and fornices, also connect the hemispheres and are present in other vertebrates. These commissures convey information between the two hemispheres to coordinate local functions.
The cerebral hemisphere has its three known poles: the occipital, frontal, and temporal poles. The median sulcus is a prominent fissure that separates the parietal lobe from the frontal lobe and the primary motor cortex from the primary somatosensory cortex.

Im going to guess that you are asking why sea levels are rising??
The rising in sea levels is due to climate change. By burning fossil fuels such as coal or oil we produce green house gasses such as carbon dioxide which are causing the climate to become warmer. This is resulting in warmer seas and warmer winters meaning glaciers and huge amounts of snow and ice are melting. It is the melting of these that is causing a rise in sea levels.
The correct answer is "source" - this is the beginning of the river. (typically in the mountains)
Mouth of a river is the "end" of the river- it's when the river joins the ocean.
A tributary is another river that ends in the main river
and the watershed is a piece of land that separates bodies of water.
The arithmetic density of a population is always lower than the physiological density, since a land's arable portion can only be a subset of it's full size.
