#74 Be Grateful for Sand

#74 Sand

Hello all fantastic followers!!

I have had an awesome day today! Sun, sun and sun all day long finished with some working in my garden and a 10km bike ride ūüôā

Great workout!

Today I wanted to talk to you about something that a lot of us tend to forget to be grateful for. It is all over the place, but it is usually never thought of!

Sand is amazing. Sand is made up of water crushing into a shoreline for thousands of years crushing bedrock ūüôā

Sand is soft and amazing! That is why I love it ūüôā

So why should I be grateful for Sand?

  • It is small.
  • It is a vital part of our¬†ecosystem.
  • You would be at a beach when you are close to sand.
  • You can make a sand castle of it!
  • You feel a great softness when you are around sand.
  • Sand has been around for millions of years.
  • It is sand on Mars.
  • Sand can be ultra hot or cold.

  • It can create beautiful images.
  • Sand is micro meters.
  • Sand is a vital part of measuring time aka hour glass.
  • Sand makes you feel like you are at a exotic place.
  • Sand can have different colors.
  • Sand is any size.
  • You can play sand football or volleyball in the sand.
  • Sand is a interesting place to end up in if you play golf.
  • Sand is warm.
  • Sand have water in it.
  • Sand is the result of millions of years of wind and water blowing onto rock.

Sand is literally the most amazing thing on planet earth and an essential part of our ecosystem.

Recently a human made space explorer Curiosity or the (Mars Space Laboratory) landed on Mars a planet in our solar system to explore the option of life.

Mars could be the turning point for making sand the most and exiting  makeup of geological matter in the solar system!

What is sand?


From Wikipedia, the free encyclopedia

Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. The composition of sand is highly variable, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz.

The second most common form of sand is calcium carbonate, for example aragonite, which has mostly been created, over the past half billion years, by various forms of life, like coral and shellfish. It is, for example, the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years, like theCaribbean.

In terms of particle size as used by geologists, sand particles range in diameter from 0.0625 mm (or ⅟16 mm) to 2 mm. An individual particle in this range size is termed a sand grain. Sand grains are between gravel (with particles ranging from 2 mm up to 64 mm) andsilt (particles smaller than 0.0625 mm down to 0.004 mm). The size specification between sand and gravel has remained constant for more than a century, but particle diameters as small as 0.02 mm were considered sand under the Albert Atterberg standard in use during the early 20th century. A 1953 engineering standard published by the American Association of State Highway and Transportation Officials set the minimum sand size at 0.074 mm. A 1938 specification of the United States Department of Agriculturewas 0.05 mm.[1] Sand feels gritty when rubbed between the fingers (silt, by comparison, feels like flour).

ISO¬†14688 grades sands as fine, medium and coarse with ranges 0.063¬†mm to 0.2¬†mm to 0.63¬†mm to 2.0¬†mm. In the United States, sand is commonly divided into five sub-categories based on size: very fine sand (‚Öü16¬†‚Äst‚Öõ¬†mm diameter), fine sand (‚Öõ¬†mm ‚Äst¬ľ¬†mm), medium sand (¬ľ¬†mm ‚Äst¬Ĺ¬†mm), coarse sand (¬Ĺ¬†mm ‚Äď 1¬†mm), and very coarse sand (1¬†mm ‚Äď 2¬†mm). These sizes are based on theKrumbein phi scale, where size in ő¶ = -log2D; D being the particle size in mm. On this scale, for sand the value of ő¶ varies from ‚ąí1 to +4, with the divisions between sub-categories at whole numbers.

The most common constituent of sand, in inland continental settings and non-tropical coastal settings, is silica (silicon dioxide, or SiO2), usually in the form of quartz, which, because of its chemical inertness and considerable hardness, is the most common mineralresistant to weathering.

The composition of sand is highly variable, depending on the local rock sources and conditions. The bright white sands found in tropical and subtropical coastal settings are eroded limestone and may contain coral and shell fragments in addition to other organic or organically derived fragmental material, suggesting sand formation depends on living organisms, too.[2] The gypsum sand dunes of theWhite Sands National Monument in New Mexico are famous for their bright, white color. Arkose is a sand or sandstone with considerablefeldspar content, derived from the weathering and erosion of a (usually nearby) granitic rock outcrop. Some sands containmagnetite, chlorite, glauconite or gypsum. Sands rich in magnetiteare dark to black in color, as are sands derived from volcanicbasalts and obsidian. Chloriteglauconite bearing sands are typically green in color, as are sands derived from basaltic (lava) with a higholivine content. Many sands, especially those found extensively inSouthern Europe, have iron impurities within the quartz crystals of the sand, giving a deep yellow color. Sand deposits in some areas contain garnets and other resistant minerals, including some smallgemstones.

If you have had interaction with sand or live close to sand embrace it for it’s fantastic power and have gratitude for it!
