The main representative cloud types for each of these forms are stratiform, cumuliform, stratocumuliform, cumulonimbiform, and cirriform. Low-level clouds do not have any altitude-related prefixes. However mid-level stratiform and stratocumuliform types are given the prefix alto-while high-level variants of these same two forms carry the prefix ...
Also sometimes called Mammatus, consisting of bubble-like protrusions on the underside caused by localized downdrafts. Arcus (including roll and shelf clouds) Low, horizontal cloud formation associated with the leading edge of thunderstorm outflow. Tuba Column hanging from the cloud base which can develop into a funnel cloud or tornado. [13]
Water is a basic necessity of life. Since two thirds of the Earth is covered by water, the Earth is also called the blue planet and the watery planet. [notes 1] The hydrosphere plays an important role in the existence of the atmosphere in its present form. Oceans are important in this regard.
Earth is the third planet from the Sun and the only astronomical object known to harbor life. This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its global ocean, covering 70.8% of Earth's crust.
Eventually, the droplets become large enough that they fall to the earth as precipitation. The collision-coalescence process does not make up a significant part of cloud formation, as water droplets have a relatively high surface tension. In addition, the occurrence of collision-coalescence is closely related to entrainment-mixing processes. [29]
Beach – Area of loose particles at the edge of the sea or other body of water; Beach cusps – Shoreline formations made up of various grades of sediment in an arc pattern; Beach ridge – Wave-swept or wave-deposited ridge running parallel to a shoreline; Bench – Long, relatively narrow land bounded by distinctly steeper slopes above and below

Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
