What can a grain of sand tell you about the Earth?

You are to describe and discuss the eight sands you examined this week. Start with the table of data you assembled on the eight sands you looked at, and continue by making an interpretation of the environment of two of the sands, how far each traveled, and their ultimate source areas.

Maui: The Maui sand had a mixed color of yellows to blacks. This collection of sand was indeed magnetite and it had a size of 1.5mm a grain. The texture of the sand was subrounded and was sand on the Wentworth Scale. It had well sorting of it's size and was composed entirely of rocks. I believe the environment of the rock was very calm. I think the waves were strong enough to mix around the colors of the rocks, but not that strong to make the shape of the rocks sharp and jagged.

Klamath California: This selection of sand was entirely black. It was very dark. But, when you put a magnet up to the sand, it didn't lift it up, meaning it was not magentic. The size of one grain was 1.5mm and it had an angular texture. Which, I believed was caused from the rough current of the waves crashing the grains on each other making the shape jagged and sharp. Klamath California was sand on the wenworth schale and the size was moderately sorted. The composition consisted of rocks.

Hampton NH: Hampton NH had very light colored grains. Some looked clear and some were pale. It was not magnetic and a grain had the size of 1.0mm. The shape of the grains were angular due to the strong waves lifting the sand and crashing them against one another. It was sand on the Wentworth Scale and was moderately sorted in size. But, of course the composition was made up of rocks.

Salinas: The Salinas consisted of a very light color. It was angular due to the smashing of the waves lifting up the rocks and them grinding against one another. The size of one grain was .33mm, making them very tiny grains composed of rocks. The sorting of the sizes was very well and they all seemed to be the same size. The salinas were not magentic at all.

Edgartown: The Edgartown sands were light in color and subrounded from the soft waves that lifted the rocks and smashed them together smoothly. The sand was not magnetic and was composed of rocks. On the Wentworth scale it was sand. As for the size, a grain was measured to 1.00mm! The sorting all though was okay and there were large, yet tiny pieces of sand.

Virgin: The Virgin sand has really cool colors. Some were light (pale, yellow) and some were dark (Black, brown). It was not magnetic, but it was very angular due to the strong waves making the sands crash hard against each other. It had a measurement of .1mm and it was poorly sorted because some grains were very large in size and some were quite tiny. The compostion of the grains was of rock and on the Wentworth Scale it was considered sand.

Saint Martin: Saint Martin sand was very light in color. It was not magnetic and it was indeed angular from the currents of the waves. It varied in size and the sorting was poor. It was composed of rocks and was sand on the Wentworth scale.

Pine Island: The color of the sand was very clear and beautiful. It was not magenetic and it was subrounded in shape. It was well sorted and it hade a size of .1mm. It was composed of rocks and was sand in the Wentworth Scale.
