Because it's entry into the atmosphere at great speed causes enough friction to light it's fire.
The Perseid meteor shower is typically best seen after midnight when the radiant point is higher in the sky. In Las Vegas, optimal viewing time is usually between 2am and dawn when the sky is darkest. Find a location away from city lights for the best viewing experience.
Topaz (8), corundum (9), and diamond (10).
A mineral with a hardness of 9, such as corundum, would not leave a streak on a streak plate because it is harder than the plate itself, which typically has a hardness of about 6. A harder mineral cannot scratch a softer material, so it wouldn't produce a streak. Streak is determined by the powder left behind when a mineral is scraped against a harder surface, and since the mineral is too hard, it cannot do so.
Where the moon is at what time depends on what phase it's in. A first quarter moon should be setting in the west at around 9 PM. If it's a little more full than that, it could well be up in the west at 9:30 PM.
It is possible to see hundreds of shooting stars in a single night, during a meteor shower.
Corundum has a streak that is typically colorless, making it difficult to determine on a streak plate. The hardness of corundum (9 on the Mohs scale) can also affect the accuracy of the streak test, as it can scratch the streak plate instead of leaving a distinct streak.

9 killstreak
Alabamas longest streak over auburn is 9 games
Two minerals that do not leave a streak on a streak plate are quartz and fluorite. Both minerals have a hardness higher than that of the streak plate, so they will not leave a streak when rubbed against it.
Topaz (8), corundum (9), and diamond (10).
You either get a 7 kill streak for an attack helicopter, 9 kill streak for a pavelow or 11 kill streak for a chopper gunner. Or you get one from a care package.
The Boston Bruins' longest streak was 14 games from December 3, 1929 to January 9, 1930
Olivia - 2009 Olivia's Dogwash Meteor Mania 2-9 was released on: USA: 21 August 2011
its 9 but if you have hardline on you need 8
