    [335] [336] The YDIH has since been refuted comprehensively by a team of earth scientists and impact experts. [337] A 2022 study using Argon–Argon dating of shocked zircon crystals in impact melt rocks found outwash less than 10 km downstream of the glacier pushed the estimate back to around 57.99 ± 0.54 million years ago, during the late ...

    The table below is arranged by the continent's percentage of the Earth's land area, and where Asian and Russian structures are grouped together per EID convention. The global distribution of known impact structures apparently shows a surprising asymmetry, [ 35 ] with the small but well-funded European continent having a large percentage of ...

    en.wikipedia.org/wiki/Water_distribution_on_Earth

    The lower mantle of inner earth may hold as much as 5 times more water than all surface water combined (all oceans, all lakes, all rivers). [19] The amount of water stored in the Earth's interior may equal or exceed that in all of the surface oceans. [20] Some researchers proposed the total mantle water budget may amount to tens of ocean masses ...
