How rare is iridium?
Iridium is considered a rare element on Earth's crust, with abundance estimated at around 0.001 ppm. It is more commonly found in meteorites than in the Earth's crust, and its rarity contributes to its high value and uses in various applications, such as in electronics and catalysis.
Hematite is composed of oxygen and what element that is less abuyndant than aluminum but more abundant than calcium?
Hematite is composed of oxygen and iron, which is less abundant than aluminum but more abundant than calcium in Earth's crust.

Most common element on earth after oxygen?
depends if you're talking about in the earths crust, in water or in the human boby. In us, carbon comes second. In the water, hydrogen. In the atmosphere ther is actually way more nitrogen than there is oxygen.
What element is not found in large quantities in Earths mantle?
The element carbon is not found in large quantities in Earths mantle.
What two elements make up more than 80 percent of the atoms found in the earths crust?
Oxygen and silicon make up more than 80 percent of the atoms found in the Earth's crust. Oxygen is the most abundant element in the Earth's crust, comprising about 46.6% of the crust by weight, while silicon is the second most abundant at around 27.7%.
Which portion of earths crust is more dense. oceanic or continental?
Oceanic
What element does the crust have more of than the mantle?
Silicon
Which element in the halogen group has 30 grams of this element in the earth's crust at any one time?
The halogen group includes fluorine, chlorine, bromine, iodine, and astatine. Among these, bromine is estimated to have about 30 grams available in the Earth's crust at any one time. This is due to its relatively low abundance compared to the other halogens, particularly fluorine and chlorine, which are more prevalent in nature.
What is the name of the earths thinnest layer?
The crust, more specifically the lithosphere.
