The earth's crust is made up of several elements: Silica, Calcium, Oxygen, Iron, Sodium, Aluminium, Manganese and so on. These elements combine in some form or other to make salts like Silicon-oxide, Calcium carbonate, Iron-oxide for example which are known as minerals and several minerals combine to make rocks. The distribution of rocks and minerals across the different parts of the globe is different, and hence geologist study different rocks/lithologies across the globe. And also this distribution will changes with depth. The upper crust has different elemental composition with respect to the lower crust. For example, the upper crust has more of aluminum with respect to lower crust whereas the lower crust ahs more Magnesium with respect to upper crust.

How do the elements in the human body compare to elements in the earths crust?
the chemical composition of human beings are similar to that found in the reminisce of stars after they impload this answer is correct human beings cant be chemically composed like earths crust because we arent formed from silicates and crystals
Earth's outermost layer is the?
Earths outermost layer is the crust.Actually, the crust is divided into two parts,Sial and Sima.In that way, actually Sial is the outermost layer of the crust,as it lies above the Sima.
What is direct evidence in science?
Physical samples of rock extracted (taken) from deep within Earths crust.
Which rock group makes up least of earths crust?
Just to say: This question refers to rock groups. Not what type of rock.Igneous rocks make up most of the earth's crust.

What is the difference between vulcanicity and volcanicity?
Vulcanicity is a process through which gaseous, liquid and solid materials are forced out of the earths crust to the earths surface. Volcanicity is the process where igneous materials reaches the earths surface from the earths crust to the earth surface
