What else can I help you with?
The remains of extraterrestrial particles that are found on earth's surface are called what?
Meteorites are material from outer space that have landed on the surface of a planet.
What are large chunks of rock found mostly in a band located between the inner planets and the outer planets?
Meteorites.
Does argon has the same number of electrons in its outer shell as magnesium metal?
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
How many numbers of electrons are on the outer ring of magnesium?
Magnesium has 2 electrons on its outer energy level.
How many electrons are in its outer energy level for Magnesium?
There are 2 outer shell electrons in Magnesium. Remember, it's in the "s" orbital, which can only accomodate 2 electrons.
Is the mantle made out of nickel and iron?
Yes, the mantle is primarily composed of silicate minerals like olivine and pyroxene, with smaller amounts of iron, magnesium, and calcium. The outer core beneath it is predominantly made of nickel and iron.
What is the mesosphere made from?
The mesosphere is composed primarily of solid and liquid rock, specifically silicate minerals, located beneath the Earth's crust and above the outer core. It consists of a mixture of magnesium silicate minerals, such as olivine and pyroxene, along with various other compounds. The temperature and pressure in this layer increase with depth, contributing to the physical state of the materials found there. The mesosphere plays a crucial role in the Earth's geology, influencing mantle convection and plate tectonics.
What are the names of the internal layers of the earth and what is the composition of each layer?
The Earth has four main internal layers: the crust, mantle, outer core, and inner core. The crust is composed primarily of silicate rocks and minerals. The mantle, beneath the crust, consists mainly of silicate minerals rich in magnesium and iron. The outer core is composed of liquid iron and nickel, while the inner core is solid and primarily made of iron and nickel.
Is gold from outer space?
Yes, gold can be found in outer space. It is thought to have been formed during stellar explosions like supernovae and collisions between neutron stars. Some asteroids and meteorites also contain gold.
Does helium has the same amount of electrons in its outer shell as magnesium?
No, helium has 2 electrons in its outer shell, while magnesium has 2 electrons in its outer shell. So, they do not have the same amount of electrons in their outer shell.
What are small fragments that have entered to earth atmosphere and fallen to surface?
Small fragments that have entered Earth's atmosphere and fallen to the surface are called meteorites. Meteorites are pieces of asteroids or comets that survive the journey through Earth's atmosphere and impact the ground. They can vary in size, composition, and shape.
What are the three types of asteroids?
A meteoroid which reaches the ground is called a meteorite. A small number of meteorites have been found which scientists believe originated on the Moon or Mars. The composition of meteorites gives us valuable information about the universe. Meteorites typically fall into one of five categories.IronsThese meteorites are made of a crystalline iron-nickel alloy that resembles the outer core of the earth. Similar in structure to some asteroids (type M), 5.7% of meteorites are irons.Stony-IronsThese meteorites are mixtures of iron-nickel alloy and non-metallic mineral matter. Scientists believe they are like the material which would be found where the Earth's core meets the mantle. 1.5% of meteorite falls are stony irons.Stony MeteoritesThere are three subclasses of stony meteorites:Chondrites: These meteorites are the most numerous, comprising 85.7% of all meteorites found. They are characterized by chondrules: small (average diameter of 1 millimeter) spheres of formerly melted minerals that have melded with other minerals to form a solid rock. Chondrites are believed to be among the oldest rocks in the solar system and are similar in composition to the mantles and crusts of earth and the other terrestrial planets.Carbonaceous Chondrites: These meteorites are very rare and contain elemental carbon, the basic building block for life on earth.Achondrites: Stony meteorites without chondrules, representing about 7.1% of meteorites. Scientists believe that some of these meteorites originate on the surface of the Moon or Mars.From http://www.odec.ca/projects/2006/jauc6s2/kinds.htm
