If the sand dune is big, there must have been strong winds and big waves in the area. If the sand dune is small, there must have been little wind and waves in that area.
No.
its the same size from your elbow to your wrist. LOL
I don't know. If you know, tell 7-Blue. I'ts complicated.
the shape and size...
The size of the orbital.
Similar: Both are formed by wind. Different: Sand dunes are formed by deposition. Snowdrifts are formed by weathering. ++ They are both formed by deposition of a granular material by the wind. Weathering is totally different - it is the breakdown of rock (or other materials) by the weather, biological agents, etc. - though sand is a product of the weathering of rock.
Typically, the smaller the grain size, the older the beach. There are some instances where this is not true though.
The size of the crystal relates to how long the crystals were forming. For example crystals that cooled slowly are larger than those cooling faster.
Its age, how it was formed, and where it was formed
How long is a piece of string - - Who can tell how much sand, as you have neglected to tell us how big this hole is. -
Sand dollars range in size, and some could only be a few ounces, while others could be towards an entire pound (a few ounces under 16 ounces).
Usually the top of the sand filter is above the water level of the pool, so all you have to do is unscrew the top and look in. However if the filter is below the pools water level you will have to cut of the water coming from and to the pool before you do. who added the sand? If you did - did you follow the manufacturer's instructions as to how much and what type of sand to use? Instructions tell you - - SPECIFICALLY - - how many pounds of # 20 silica sand to use.
Sand is a heterogeneous mixture because you can tell with the naked eye that it is different.
Your filter will tell you on the side of it how much media sand to put in it.
sand
you tell me smarty
The fossilized ripples tell us about the environmental conditions when the rock was formed
