- Sandstone (sometimes known as arenite) is a clastic sedimentary rock composed mainly of sand-sized minerals or rock grains. Most sandstone is composed of quartz and/or feldspar because these are the most common minerals in the Earth's crust. It also makes for good Windows Backgrounds.

The American Community Gardening Association (ACGA) is a bi-national nonprofit membership organization of professionals, volunteers and supporters of community greening in urban and rural communities. The Association recognizes that community gardening improves people’s quality of life by providing a catalyst for neighborhood and community development, stimulating social interaction, encouraging self-reliance, beautifying neighborhoods, producing nutritious food, reducing family food budgets, conserving resources and creating opportunities for recreation, exercise, therapy and education.

- A hydrothermal vent is a fissure in a planet's surface from which geothermally heated water issues. Hydrothermal vents are commonly found near volcanically active places, areas where tectonic plates are moving apart, ocean basins, and hotspots.
A black smoker or sea vent is a type of hydrothermal vent found on the seabed, typically in the abyssal and hadal zones. They appear as black, chimney-like structures that emit a cloud of black material. Black smokers typically emit particles with high levels of sulfur-bearing minerals, or sulfides.White smoker vents emit lighter-hued minerals, such as those containing barium, calcium and silicon. These vents also tend to have lower temperature plumes.
This is a recording of a black smoker.

Cinnabar (HgS)
Cinnabar is the chief mineral composed of the element mercury, and is a very important ore mineral. Though most Cinnabar is massive and uninteresting in habit, several localities produce phenomenal and strikingly colored red crystals that stand out with beautiful contrast on top of a white matrix. - See more about Cinnabar here!
Diamond (C)
Diamond has many unequaled qualities and is very unique among minerals. It is the hardest known substance, it is the greatest conductor of heat, it has the highest melting point of any substance (7362° F or 4090° C), and it has the highest refractive index of any natural mineral. Diamond is number 10 on the Mohs scale, and is 40 times harder than Corundum, which is number 9 on the Moh's scale. It also has the most dense atomical configuration of any mineral, and is transparent over the greatest number of wavelengths. Because of heat conduction, Diamonds are cold to the feel at or below room temperature. When heated, a Diamond will remain hot long after the heat source is removed. - See more about Diamond here!

Topographic Map w/ Running Water Streaks
4 Different Types of Maps:
1: Dot Density Map
This is as a map type that uses a dot symbol to show the presence of a feature or phenomenon. Dot maps rely on a visual scatter to show spatial pattern.
2: Proportional Symbol Map
The proportional symbol map is a widely-used form of thematic mapping. In this technique, the cartographer selects a symbol and alters its size, the area to be exact, based on the data values.
3: Choropleth Map
This map is a thematic map in which areas are shaded or patterned in proportion to the measurement of the statistical variable being displayed on the map, such as political party selection for states.
4: Isarithmic Map
Isarithmic maps are maps that represent data sets that have a "continuous distribution" and "smooth change in value."
