  2. List of impact structures on Earth - Wikipedia

    en.wikipedia.org/wiki/List_of_impact_structures...

    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, [ 37 ] with the small but well-funded European continent having a large percentage of ...

    en.wikipedia.org/wiki/File:Crater-depth-diagram.svg

    English: How crater-depth is measured, using the side-view of a typical crater. Depth "A" measures from the surface to the bottom of the crater. Depth "B" measures from the mean height of the rim to the bottom of the crater.

  4. Crater depth - Wikipedia

    en.wikipedia.org/wiki/Crater_depth

    The depth of an impact crater in a solid planet or moon may be measured from the local surface to the bottom of the crater, or from the rim of the crater to the bottom. Crater depth diagram. The diagram above shows the full (side) view of a typical crater. Depth "A" measures from the surface to the bottom of the crater.

  5. Volcanic field - Wikipedia

    en.wikipedia.org/wiki/Volcanic_field

    The north face of Mount Garibaldi rises above The Table and Garibaldi Lake in the Garibaldi Lake volcanic field. A volcanic field is an area of Earth's crust that is prone to localized volcanic activity. The type and number of volcanoes required to be called a "field" is not well-defined. [1]

  6. Complex crater - Wikipedia

    en.wikipedia.org/wiki/Complex_crater

    A central-peak crater is the most basic form of complex crater. A central-peak crater can have a tightly spaced, ring-like arrangement of peaks, thus be a peak ring crater, though the peak is often single. [3] Central-peak craters can occur in impact craters via meteorites. An Earthly example is Mistastin crater, in Canada. [1]

  7. List of possible impact structures on Earth - Wikipedia

    en.wikipedia.org/wiki/List_of_possible_impact...

    The following tables list geological features on Earth that are known impact events as well as possible, but for which there is currently no confirming scientific evidence in the peer-reviewed literature, impact events. In order for a structure to be confirmed as an impact crater, it must meet a stringent set of well-established criteria. Some ...

  8. Rootless cone - Wikipedia

    en.wikipedia.org/wiki/Rootless_cone

    The explosive gases break through the lava surface in a manner similar to a phreatic eruption, and the tephra builds up crater-like forms which can appear very similar to real volcanic craters. Well known examples are found in Iceland such as the craters in the lake Mývatn (Skútustaðagígar), the Rauðhólar in the region of the capital city ...

  9. Multi-ringed basin - Wikipedia

    en.wikipedia.org/wiki/Multi-ringed_basin

    Valhalla Basin on Jupiter's moon Callisto, taken by Voyager 1. A multi-ringed basin (also a multi-ring impact basin) is not a simple bowl-shaped crater, or a peak ring crater, but one containing multiple concentric topographic rings; [1] a multi-ringed basin could be described as a massive impact crater, surrounded by circular chains of mountains [2] resembling rings on a bull's-eye.
