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.
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
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.
Physical samples of rock extracted (taken) from deep within 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.
In ice.

They can be found in the earths crust.
Many different minerals are found in oceanic crust. Feldspar, basalt, pyroxene, and other molten rock materials make up the composition of the ocean's crust.

A vent in the Earth's crust from which lava and other materials are ejected is called a volcano.
