What are the 5 most common minerals?
The five most common mineral groups in rock are the silicates, carbonates, sulfates, halides, and oxides.
There are about 4000 known minerals in the Earth’s crust, and about 92 % of them are silicates..
What are the 7 major minerals?
The major minerals, which are used and stored in large quantities in the body, are calcium, chloride, magnesium, phosphorus, potassium, sodium, and sulfur.
What’s in the earth’s core?
Unlike the mineral-rich crust and mantle, the core is made almost entirely of metal—specifically, iron and nickel. The shorthand used for the core’s iron-nickel alloys is simply the elements’ chemical symbols—NiFe. Elements that dissolve in iron, called siderophiles, are also found in the core.
What are the 13 essential minerals?
They include calcium, phosphorus, magnesium, sodium, potassium, chloride and sulfur. You only need small amounts of trace minerals. They include iron, manganese, copper, iodine, zinc, cobalt, fluoride and selenium. Most people get the amount of minerals they need by eating a wide variety of foods.
What is the oldest land on earth?
This natural “desert pavement” in Israel’s Negev Desert has been dated to about 1.8 million years old, the olest known vast expanse of surface area on the planet.
How old is the oldest fossil on Earth?
3.5 billion yearsCyanobacteria: Fossil Record The oldest known fossils, in fact, are cyanobacteria from Archaean rocks of western Australia, dated 3.5 billion years old. This may be somewhat surprising, since the oldest rocks are only a little older: 3.8 billion years old!

What is the thickest layer of the earth?
mantleThe mantle At close to 3,000 kilometers (1,865 miles) thick, this is Earth’s thickest layer. It starts a mere 30 kilometers (18.6 miles) beneath the surface. Made mostly of iron, magnesium and silicon, it is dense, hot and semi-solid (think caramel candy).
What is the hardest mineral on Earth?
DiamondHard – cannot be scratched by a knife but can scratch glass, Mohs’ 6-9; Diamond is the hardest known mineral, Mohs’ 10.

What is the oldest crystal on Earth?
zirconA tiny 4.4-billion-year-old crystal has been confirmed as the oldest fragment of Earth’s crust. The zircon was found in sandstone in the Jack Hills region of Western Australia. Scientists dated the crystal by studying its uranium and lead atoms.
What are the 8 elements that make up 98 of the Earth’s mass?
Mantle. The mass-abundance of the eight most abundant elements in the Earth’s mantle (see main article above) is approximately: oxygen 45%, magnesium 23%, silicon 22%, iron 5.8%, calcium 2.3%, aluminum 2.2%, sodium 0.3%, potassium 0.3%.

What was the first mineral on Earth?
We concluded that the first mineral was diamond—pure carbon condensed from the expanding atmospheres of energetic stars. Approximately a dozen “ur-minerals,” including nitrides, carbides, oxides, and silicates, condensed as micro-crystals at temperatures greater than 1500°C.
