Answer 2

Химический состав ядра, мантии и земной коры

Ядро Земли: The Earth's core is primarily composed of iron and nickel. The outer core is believed to be in a liquid state, while the inner core is solid due to the immense pressure at the center of the Earth.

Мантия: The mantle is composed mainly of silicate rocks rich in magnesium and iron. It is divided into the upper mantle and the lower mantle. The upper mantle is composed of peridotite, a type of ultramafic rock, while the lower mantle is believed to consist of more iron-rich silicate minerals.

Земная кора: The Earth's crust is primarily composed of oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium. It is divided into oceanic and continental crust. The oceanic crust is mainly composed of basalt, while the continental crust is primarily composed of granite and other igneous rocks.

These compositions are based on scientific studies and geological research, providing insights into the materials that make up the different layers of the Earth.
