Explanation:
My answer -
<span>There are typically two
planets that are dubbed as Earth's twin. The first one, Venus, is called
Earth's twin because of its similar size, and how it is the closest
planet to Earth. But, scientists discovered that Venus's atmosphere and
temperature were totally different from Earth's. The other planet also
called Earth's twin is Mars. Mars is believed to have a large ocean on
the past. Some even say that life may have developed on Mars for a short
period of time. Furthermore, Mars has an average temperature of -70
degrees Fahrenheit, closest to Earth than any other planet. It seems that
water and life define the Earth, and if Mars has these characteristics,
it would truly be Earth's twin.
P.S
Have an AWESOME!! day :)

Answer:
Quartzite is a metamorphic rock formed when quartz-rich sandstone or chert has been exposed to high temperatures and pressures. Such conditions fuse the quartz grains together forming a dense, hard, equigranular rock. The name quartzite implies not only a high degree of induration (hardness), but also a high quartz content. Quartzite generally comprises greater than 90% percent quartz, and some examples, containing up to 99% quartz, and are the largest and purest concentrations of silica in the Earth's crust. Although a quartz-rich sandstone can look similar to quartzite, a fresh broken surface of quartzite will show breakage across quartz grains, whereas the sandstone will break around quartz grains. Quartzite also tends to have a sugary appearance and glassy lustre. The variety of colours displayed by quartzite are a consequence of minor amounts of impurities being incorporated with the quartz during metamorphism. Although quartzite can sometimes appear superficially similar to marble, a piece of quartzite will not be able to be scratched by a metal blade, and quartzite will not fizz on contact with dilute hydrochloric acid.Explanation:
