  2. Celiac plexus - Wikipedia

    en.wikipedia.org/wiki/Celiac_plexus

    The celiac plexus is often popularly referred to as the solar plexus. In the context of sparring or injury, a strike to the region of the stomach around the celiac plexus is commonly called a blow "to the solar plexus". In this case it is not the celiac plexus itself being referred to, but rather the region around it.

  3. Origin of water on Earth - Wikipedia

    en.wikipedia.org/wiki/Origin_of_water_on_Earth

    The boundary of the region where ice could form in the early Solar System is known as the frost line (or snow line), and is located in the modern asteroid belt, between about 2.7 and 3.1 astronomical units (AU) from the Sun. [23] [24] It is therefore necessary that objects forming beyond the frost line–such as comets, trans-Neptunian objects ...

    en.wikipedia.org/wiki/Solar_Plexus_(disambiguation)

    The celiac plexus (or solar plexus) is a complex network of nerves located in the abdomen. Solar plexus or Solar Plexus may also refer to: The solar plexus chakra in Hinduism, see Manipura

  5. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    When comparing a polar and nonpolar molecule with similar molar masses, the polar molecule in general has a higher boiling point, because the dipole–dipole interaction between polar molecules results in stronger intermolecular attractions. One common form of polar interaction is the hydrogen bond, which is also

  6. Water on terrestrial planets of the Solar System - Wikipedia

    en.wikipedia.org/wiki/Water_on_terrestrial...

    The best constraints for accreted H 2 O are determined from non-atmospheric H 2 O, as the D/H ratio of the atmospheric component may be subject to rapid alteration by the preferential loss of H [22] unless it is in isotopic equilibrium with surface H 2 O. Earth's VSMOW D/H ratio of 1.6×10 −4 [7] and modeling of impacts suggest that the ...

  7. Properties of water - Wikipedia

    en.wikipedia.org/wiki/Properties_of_water

    Water (H 2 O) is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, which is nearly colorless apart from an inherent hint of blue. It is by far the most studied chemical compound [ 20 ] and is described as the "universal solvent " [ 21 ] and the "solvent of life". [ 22 ]

  8. Extraterrestrial liquid water - Wikipedia

    en.wikipedia.org/wiki/Extraterrestrial_liquid_water

    Absorption spectrum of liquid water Liquid water has not been detected in spectroscopic analysis of suspected seasonal Martian flows. Liquid water has a distinct absorption spectroscopy signature compared to other states of water due to the state of its hydrogen bonds. Despite the confirmation of extraterrestrial water vapor and ice, however ...

  9. Ocean world - Wikipedia

    en.wikipedia.org/wiki/Ocean_world

    Earth's surface is dominated by the ocean, which forms 75% of Earth's surface.. An ocean world, ocean planet or water world is a type of planet or natural satellite that contains a substantial amount of water in the form of oceans, as part of its hydrosphere, either beneath the surface, as subsurface oceans, or on the surface, potentially submerging all dry land.
