gravel sand talus detritus broken up rock?
because the nutrients in the sand differ and that's what makes the sand the color
Sand is composed of bits of rock that have been broken down to a small size.
Sand is broken up rock. It depends what sort of rock is broken up. If you break up black lava, you get black sand.
Often found in sand is broken down rock particles and dead organisms.
Erosion/gathering which generates sand.
The three types of weathered rock particles found in soil are sand, silt, and clay. Sand particles are the largest, followed by silt, and clay particles are the smallest.
MOST sand consists of broken down rock (silica dioxide). However, on islands, such as Hawaii, most sand is broken down coral (calcium carbonate). This is why most beaches in Hawaii are tan colored, and not white.
Sand is created through weathering and erosion. It is, essentially, just a whole bunch of bits of rock, shells, fossils, etc. Say there is a rock. The rock is exposed to wind, water, ice, etc. Slowly, this rock gets weathered away. By weathering I mean that it gets broken down into smaller and smaller pieces, which are carried away. Over time, that rock will be completely broken down into smaller sediments. Those sediments are, in effect, sand grains.
A tiny piece of sand is called a grain of sand.
Grains: Grains that are not crystals in rock do not have flat shiny faces. They are rounded, like grain of sand, or jagged, like a piece of broken rock. Grain Size: Grain size in rocks can mean the size of crystal grains or of fragments: Coarse Grained: most of the rock is made of grains as largeas rice, or larger.
