Is peridot a crystal?

Peridots are not crystals because crystals are made out of water and salt but a peridot isn't. It would be counted as a gem. It is the August gemstone. It is also purple. People can find it by cracking large perilouscaisuj the science term or ina cave full of rocks.


If two objects meets head-on with the same mass and speed what is the collision?

AnswerProvided the objects are of identical density and structure, particles would exit on an axis perpendicular to the axis of attraction, until secondary fragment collisions alter their trajectory.If the density of the objects is significantly different, the object of lesser density would be destroyed with the object of greater density taking only superficial damage if any. Physical shape and the cleavage of the material could also play a part in this.(o well hope this is right lol dont pay me no mind tho)


What is the dress code for Jupiter high school?

Well, honey, at Jupiter High School, the dress code is pretty straightforward: cover your bits and pieces, keep the offensive slogans off your clothes, and don't try to sneak in your pajamas. Basically, just use some common sense and you'll be fine. And remember, fashion faux pas are so last season!


What are facts about topaz?

* Color is clear, yellow, orange, red, blue and green. * Luster is adamantine to vitreous. * Transparencycrystals are transparent to translucent. * Crystal System is orthorhombic; 2/m 2/m 2/m * Crystal Habits include a prismatic crystal with usually two different prisms that produce a rounded or sharp diamond-shaped cross-section. The termination is typically capped by a dome forming a roof like top. Another dome can modify the termination producing a point at the juncture of the two domes. A basal pinacoid can flatten the prisms termination or truncate the top of the domes. The pinacoid, multiple domes and occassionally orthorhombic pyramid faces can produce a complex, multifaceted and well formed termination. Topaz can be granular and massive. * Cleavage is perfect in one direction, basal. * Fracture is conchoidal. * Hardness is 8. * Specific Gravity is approximately 3.4 - 3.5+ (above average) * Streak is white. * Associated Minerals include quartz, tourmalines, micas, brookite, cassiterite and fluorite. * Other Characteristics: index of refraction is 1.61 - 1.64. Prism faces maybe striated lengthwise. * Notable Occurrences include Minas Gerias, Brazil; Pakistan; San Diego Co, California; Ural Mountains, Russia; Mexico and the Thomas Range, Utah. * Best Field Indicators are crystal habit, color, density and hardness.
