In addition, damage to the central nervous system and peripheral nervous system can occur from chronic alcohol abuse. The long-term use of alcohol is capable of damaging nearly every organ and system in the body. The developing adolescent brain is particularly vulnerable to the toxic effects of alcohol.
TYPES OF CONTINENTAL MARGINS. Continental margins are not all alike, but they are not all different either. There are two basic types. Each one has different characteristics, which are a function of the processes involved in the formation of the two types of margins. The âclassicâ margin is based on the U.S. East Coast example.
The Continental Shelf. The Continental Shelf is the gently sloping undersea plain between a continent and the deep ocean. The continental shelf is an extension of the continent's landmass under the ocean. Much of the continental shelf was exposed dry land during glacial periods.During interglacial periods, like today, the shelf is submerged under relatively shallow waters.he continental shelf is an extension of the continent's landmass under the ocean.
