Pores (the spaces that exist between soil particles) provide for the passage and/or retention of gasses and moisture within the soil profile.The soil's ability to retain water is strongly related to particle size; water molecules hold more tightly to the fine particles of a clay soil than to coarser particles of a sandy soil, so clays generally retain more water.

The agricultural practice of tilling decreases the degree of soil water repellency. Tilling crop fields reduces the carbon content of the soil through mixing and mineralization, thus decreasing the likelihood of decomposition by microorganisms that can lead to the dispersal of the hydrophobic coating that triggers soil water repellency.

This creates a cloudy water column which travels under the tidal influence as the wave orbital motion is in equilibrium. The Null-point hypothesis has been quantitatively proven in Akaroa Harbour, New Zealand, The Wash , U.K., Bohai Bay and West Huang Sera, Mainland China, and in numerous other studies; Ippen and Eagleson (1955), Eagleson and ...
The famous "black sand" beaches of Hawaii, such as Punaluʻu Beach and Kehena Beach, were created virtually instantaneously by the violent interaction between hot lava and sea water. [2] Since a black sand beach is made by a lava flow in a one time event, they tend to be rather short lived since sands do not get replenished if currents or ...
Water from springs is usually clear. However, some springs may be colored by the minerals that are dissolved in the water. For instance, water heavy with iron or tannins will have an orange color. [3] In parts of the United States a stream carrying the outflow of a spring to a nearby primary stream may be called a spring branch, spring creek ...
A lava lamp is a novelty item that contains wax melted from below by a bulb. The wax rises and falls in decorative, molten blobs. The wax rises and falls in decorative, molten blobs. Sealing wax was used to close important documents in the Middle Ages .

The latter covers reactions to water, atmospheric gases and biologically produced chemicals with rocks and soils. Water is the principal agent behind both kinds, [1] though atmospheric oxygen and carbon dioxide and the activities of biological organisms are also important. [2] Biological chemical weathering is also called biological weathering. [3]
