    Tsunami roots that enable them to thrive in brackish water (brackish water is salty,

    but not as salty as seawater).


    Tsunami, Japanese word meaning “harbor wave,” used as the
    scientific term for a class of abnormal sea wave that can cause catastrophic There are several species of mangrove trees found all over the

    undersea earthquake, an undersea landslide, the eruption of an undersea large fresh water source (such as a river). Some prefer areas that are
