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.
Profile illustrating the shelf, slope and rise. The continental margin is the zone of the ocean floor that separates the thin oceanic crust from thick continental crust.Together, the continental shelf, continental slope, and continental rise are called continental margin. Continental margins constitute about 28% of the oceanic area.arthquakes and volcanic eruptions are common on the west coast of North America, but there are no active volcanoes on the east coast and large magnitude earthquakes are rare. Geologists refer to the west coast as (tectonically) active continental margin and the east coast a passive continental margin.
