Черное море со всех сторон окружено сушей, а проливы Босфор и Дарданеллы соединяют его с Средиземным морем. В Черное море впадает множество рек. Из-за малой солености снижено биоразнообразие Черного моря: обитатели морей и океанов плохо переносят соленость меньше 20‰. Поверхностная вода Черного моря - менее соленая и более легкая, близкая по температуре к воздуху; летом она прогревается, зимой - охлаждается. Это - знакомое нам Черное море: в нем мы плаваем и ныряем, ловим рыбу. Cовсем другие - глубинные воды Черного моря: от 50-100м - до самого дна, лежащего на глубине двух километров - более соленые и тяжелые, их температура всегда постоянна: 9oС. - свойства вод Черного моря
