Extraterrestrial liquid water phases of ice are thought to underlie the liquid water layer. Models of radioactive decay suggest that MOA-2007-BLG-192Lb, a small planet orbiting a small star could be as warm as the Earth and completely covered by a very deep ocean. Models of Solar System objects indicate the presence of liquid water in their internal differentiation. Some models of the dwarf planet Ceres, largest object in the asteroid belt indicate the possibility of a wet interior layer. Water vapor detected to be emitted by the dwarf planet may be an indicator, through sublimation of surface ice. A global layer of liquid
Oil and gas law in the United States for it is paid without deducting costs of drilling, completing, or operating the well. Whether or not the operator can deduct costs of treating, transporting, or marketing the oil and gas, if not specified in the lease, has been a matter of legal dispute.

In an "unless-delay rental" lease, a lessee agrees to pay delay rentals
