It makes the ground for our strolls on beach, we use it in building our houses or roads and some artists use it to create beautiful sand sculptures. Most people do not think about sand. In this piece of writing we will try to get to know our way around sand.

The size of sand granules comprises of particles that are as small as 0.0625 mm to as large as 2 mm. A sand particle that falls into this range is termed as sand grain. These same granules become silt when their size comes in the following range: below 0.0625 mm all the way down to 0.004 mm in diameter. When the particles range from 2 mm to 64 mm they become gravel.

Have you given some thought to the composition of sand? Where does it come from? Let me tell you, sometimes sand is a deposit, mostly comprising of organic matter such as sea shells, erosion material from coral leaves, bits and pieces from the skeletons of sponges or other marine organisms. More often than not, the actual source of san is high in the mountains and is carried to far off river banks with the water that flows from the mountains.

If you have a chance of looking at sand samples that come from beach you will see that these grains are very smooth and clear due to the constant wash of waves. On the other hand, sand dunes give a rather dull and round appearance. The reason being that they are blasted away by the wind for miles and miles before settling down which is also the case with desert sand.

One of the major mineral that you might find in the sand is quartz. Quartz is quite hard and is a mixture of oxygen and silicon. Despite its hardness, quartz is light weight and is easily carried away by wind to form sand dunes.

The sand thrown out as a result of explosive volcanic eruption is volcanic ash. This type of sand is way too hot for our liking. But why is it so hot? Taking a closer look reveals that volcanic ash comprises of glassy material such as lava grains and pumice which give it blackish and rough appearance and higher temperatures.

The world of sand is very interesting. You might want to take out some time and explore it. So the next time you have sand delivery at your door step, take some of it and look at it with the microscope. I bet you will be surprised!
