What is found in the center or every hail stone?

a speck of dust for the water to condense around!

Iridium is a mineral found along the K/T boundary.  Some scientists speculate that iridium is not a native mineral to Earth and is only found here in a thin layer along the surface because of the huge meteor impact that apparently killed off the dinosaurs.

One of the greatest mineral deposits on the planet, the Sudbury, Ontario nickel region, is the result of an ancient meteor impact.  The crater so created was deep enough to tap into molten mantle rock, which partially filled the crater.  Parts of this infill are sulphide rich and form the ore deposits.\n\nThere is some controversy about how much of the nickel and other metals were contributed by the bolide and how much was terrestrial material that was mobilized and focused by the impact structure.\n\nOther ore deposits may be the results of impact structures but Sudbury is the best example.

it's the core of the earth. lava. melted rock.etc

I say every single transitional metal is found on every single continent in the world in some quantity.  The most abundant T metal?  I'd say iron.

Warm fronts (lows, low pressure) ride over the top of cold fonts (highs, high pressure).  The winds are going in different directions and can spawn tornadoes.  Also, the water vapor in the warm front air cools as it gains altitude and produces rain.  If there is a lot of turbulence, the water can freeze into droplets of ice which keep going up and down and around in the turbulence produced by the interaction of these air masses.  This produces hailstones.\n\nWarm air is light and laden with water vapor.\nCold air is dryer usually, and always heavier than warm air.\n\nSo you got some different kinds of weather there.\n\nHuge masses of warm, water laden air are found in hurricanes.  The water is in huge, towering masses of clouds.\n\nIn the northern hemisphere, warm air masses (lows) spin counterclockwise.  Cold air masses (highs) spin clockwise.\n\nWarm air comes mostly from the south, cold air from the north.  However, air masses are steered by the Jet Stream also.  Maybe your next topic.\n\nHurricanes have the lowest pressure of all (low barometer reading).

Hail cannons disrupt stop hail from forming and destroying crops. Hail cannons ignite a charge of acetylene gas in a specially designed blast chamber releasing an explosive pressure wave creating a cavitation effect which disrupts the formation process of the hail stone embryo.\n\nhttp://www.hailcannon.com

Snow grains are tiny circular bits of snow - i.e., no bigger than a grain of sand (hence the name). What you are probably referring to are snow pellets - larger hard balls of snow. You are not seeing those if you think they might be hail. There are also ice pellets - small balls of ice (frozen raindrops).\n\nWe like to classify things, but sometimes it is ambiguous. E.g., if a snowflake collides with a raindrop and freezes, it may look very much like an ice pellet but with a little white frozen spot inside. That would not be hail, because hail as mentioned requires  the formation of layers from vertical motions in the clouds. You may be seeing hail, but at this time of year I think it more likely is some sort of mixture between and ice and snow pellets.

Actually a storm came through Fort Worth in about 1995, the sky was about as green as a lilly pad.  We didn't get the severe weather where I lived, but FW got grapefruit sized hail in the park that actually killed several people.  Now that I study and work in weather I know what causes the green discoloration when the light refracts off hailstone in the air it causes a light green light, with more widespread and intense hail you get the darker green

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

I would have to say to check out this site:\n\nhttp://www.obliquity.com/skyeye/misc/meteor.html\n\nThere is a chart a little ways down the page.  I hope that helps.

whats at the center of the earth is a great mystery some scientist would say it is a ball of iron others a ball of solid uranium we just dont know for sure Haley the man that discoved haleys comet way back in the day said the earth is hollow so scientists just have unproven theorys they dont know for sure until they get there

The largest meteorite ever found is the Hoba meteorite of South Africa.  It weighed 60 tons.  The smallest meteorite would be the size of dust or even smaller (depending on whether or not you were using a magnifying glass as a visual aid)

Encke is believed to be the origin of the Taurid Meteor shower.\n\nIn terms of direct impact on Earth, it is theorized that Encke is the remains of a larger comet that split apart during the Bronze Age with the other chunk landing in the Fertile Crescent.  Evidence of this is an impact crater in Iraq.\n\nAnother theory is that the swastika symbol, which is found in variants in ancient cultures all over the world, was a representation of how Encke appeared with four 'arms' spiraling from its central nucleus.

It erupts from he center point of the ridge from underneath the crust of the Earth. The center is the oldest point, seeing as how the material flows away from the peak of the ridge. It's like Earth's pressure valve, Hawaii was formed a bit like this.
