Petrified wood is a type of fossil: it exists of fossil wood where all the organic materials have been replaced with minerals (most often a silicate, such as quartz), while retaining the original structure of the wood. The petrifaction process has occurred underground, when wood became buried under sediment. Mineral-rich water flowing through the sediment deposited minerals in the plant's cells and as the plant's lignin and cellulose decayed away, a stone cast was formed in its place.\n\nMinerals such as manganese, iron, and copper in the water/mud during the petrification process give petrified wood a variety of color ranges. Quartz crystals are colorless, but when iron is added to the process the crystals become stained with a yellow or red tint.

This is too much for asking here.  You need to go to the Library and ask a reference librarian to steer you to\n book(s) with wind patterns and ocean currents. You might find it on the Web, but a good atlas that include this information will be easier to understand and find.  \n\nPS  When you are asking a question that is scientific in nature be sure to use correct grammer.  I am not sure what location goes with another or if they are separate. Use correct grammer relating to commas for a series. Cali? Is that the abbreviation for California?  No, the abbreviation is CA now, although before the Post Office got involved it was usually Cal.  Cali is slang.

rock, and the depth will be different wherever you decide to dig. there are even deserts that don't have any sand at all, just exposed rock and "normal" earth everywhere.

Sand Dollars are most like sea urchins, or the little prickly balls that you find at the bottoms of oceans. When they are alive, they have small, tiny spines that surround the entire shell, making it feel like velvet. When you see them washed up and dead on the beach, you can't feel the velvety 'skin' and spines on their shell because of their exposure to the sun. Sand Dollars are also found at the bottoms of oceans, and in shallow salt waters they are found just beneath the surface of sandy or muddy areas. Sand Dollars aren't plants, they are marine animals. And no, they don't hold an animal inside, but they are still a treasure! :D In fact, they got their name 'sand dollar' because people used to think that they were mermaid money.\n\nHope this helps!

Deep End of the Ocean??? it sounds similar to that

I've known that for years.  I thought it was common knowledge.  \n\nI am interested in this ocean front property in Arizona.  If I buy would you throw in the Golden Gate in free?\n\nThanks

Sedimentary rocks can be divided into two major informal groups, referred to as clastics (or siliciclastics) and carbonates. Clastic rocks are formed by erosion of other rocks, igneous, metamorphic and sedimentary. These 'clasts' can be mud, silt, sand, cobbles, or boulders, and are transported by wind, water, or gravity and accumulate where they eventually are buried and pressure and temperature subject them to diagenesis, the process that makes them from unconsolidated clasts to one rock mass. Shale, sandstone, and conglomerate are examples of clastics.\n\nCarbonates can work much differently since they form primarily in the oceans. Many carbonates are made from reefs and other living organisms that grow in the ocean. As these organisms die and leave behind their carbonate skeletons, rocks are formed. Other carbonates are formed from small grains called ooids, small balls that form by precipitating out of sea water, possibly with the help of bacteria or algae. Some ocean algae even form carbonate 'mud' that eventually becomes hard rock. \n\nAnother unusual group of sedimentary rocks are called evaporites. These are rocks like gypsum and rock salt that are deposited by evaporation of water in confined basins. \n\nThe most fascinating part about sedimentary rocks is that they have a past, each one tells a story.

The Chinese in Kern County California mined crude from the surface by buckets ! being the crude was on the surface ! If you research ? do so by Los Angeles County, being that Kern was formed by taking part of Los Angeles County and part of Tulare County ! Most drugs are oil based ! If you remove the weight of oil from the location does our planet adjust to being out of balance ! Since the introduction of fossil fuel for power !" why is it that everything has advanced in technology except our burning of fossil fuel" (hint=greed),

Here is one of the best websites on the deserts of the Southwestern USA, which includes desert life, some geology, and descriptions of the deserts.\nhttp://www.desertusa.com/flow.html\n\nCalifornia has some wondrous deserts, with miles and miles of open wild spaces. The main deserts in California are the Sonoran Desert, the Mojave Desert, and portions of the Great Basin Desert. Other names exist in common usage for some portions of these deserts. \n\nThere is also a list of good books on deserts on the DesertUSA website:\nhttp://www.desertusa.com/web_cart/db/pages/chi.html\n\nTo learn more about what conditions create a desert check out the UC Berkeley website on Desert Biomes at:\nhttp://www.ucmp.berkeley.edu/glossary/gloss5/biome/deserts.html\n\nThe USGS is another great resource for information on deserts:\nhttp://pubs.usgs.gov/gip/deserts/

Sand was not invented.  It was created naturally by waves or other force erroding pieces of quartz (a rock) and making it smaller.

"Red Crag" can be found at Walton-on-the-Naze, near Essex England ... among several other areas.\n\nThe Pliocene rocks of Britain now occupy but a small area in Norfolk, Suffolk and part of Essex; but from the presence of small outlying patches in Cornwall (St Erth and St Agnes), Dorsetshire (Dewlish) and Kent (Lenham), it is evident that the Pliocene Sea covered a considerable part of southern England. Moreover, these patches show by their present altitude above the sea that the Downs of Kent must have been elevated more than 850 ft., and the west coast of Cornwall 400 ft. since Pliocene times. The Pliocene rocks rest with strong unconformity upon the older strata in Britain. In the eastern counties the shelly, sandy beds are called "Crag"; this name has come into very general use for all the members of the series, and it is frequently employed as a synonym for Pliocene. \n\nThe Red Crags are sandy, marine, shallow-water deposits, with an abundant fauna; they vary rapidly from point to point, and in general the more southern localities are richer in southern (older) forms than those farther north.

Either go to a local stone quarry...if you have one.  Or maybe try talking to a landscaper...they should have some advise on how to obtain a big rock.  Good luck!

hard to say. i found lots of things in the desert. my husband is a geologist. if you mail me a picture, i will have him look at it.\nthere is lot of crystal stuff in egyptian deserts, most are worthless unless you enjoy it as decoration in your house. does it has a greenish tone in the bottom of the crystals? i have lots of them. it depends also where you found it. if it was near a roman settlement, it could be ancient glass, but if it scratch glass now, i doubt it. i found lots of this, but not this big of a piece, that would be uncommon. tell me more about it, maybe i can help you.\n\nsend me a picture...susuegypt@hotmail.com

Yes, it sounds like you have a geode.  The word "geode" comes from a Greek word, meaning "earth shaped".  They can be oblong or shaped like invertebrate fossils. Some are hollow and lined with most beautiful and unusual layers and clusters of various mineral crystals, but others are completely filled by inward-growing crystals.\n\nCheck out this website.  It has lots of pictures of geodes and lots more information.  I hope this helps.
