Answer 1

Объяснение:

Байка́л — озеро тектонического происхождения в южной части Восточной Сибири, глубочайшее озеро планеты Земля, крупнейший природный резервуар пресной воды. Более половины года озеро сковано льдом, период ледостава 15 января — 1 мая, судоходство осуществляется с июня по сентябрь. С 1956 года озеро стало составной частью Иркутского водохранилища, в результате чего уровень воды поднялся на 1.5 м.

Байкал находится в центре Азии, в России, на границе Иркутской области и Республики Бурятия. Озеро протянулось с севера на юго-запад на 636 км в виде гигантского полумесяца. Ширина Байкала колеблется от 25 до 80 км.

Максимальная глубина озера — 1 637 метра была открыта в 1983 году Л. Г. Колотило, и А. И. Сулимовым во время выполнения гидрографических работ экспедицией ГУНиО МО СССР.

В Байкал впадает 336 рек и ручьёв, однако это число учитывает лишь постоянные притоки. Самые крупные из них — Селенга, Верхняя Ангара, Баргузин, Турка, Снежная, Сарма. Из озера вытекает одна река — Ангара.
