Question

compare and contrast the earths crust, mantle, and core including temperature, density, and composition.

Explanation:

The Earth's crust is the outermost layer. It has a relatively low temperature (surface - a few hundred degrees Celsius in some areas like volcanoes), low density (about 2.7 - 3.0 g/cm³ for continental crust and 2.9 - 3.3 g/cm³ for oceanic crust), and is composed of silicate rocks (e.g., granite for continental, basalt for oceanic).

The mantle is below the crust. It has higher temperatures (ranging from about 500°C near the crust - mantle boundary to 4000°C near the core - mantle boundary), higher density (3.3 - 5.7 g/cm³), and is composed of silicate minerals like olivine, pyroxene.

The core (outer and inner) has extremely high temperatures (outer core around 4000 - 5500°C, inner core up to 5500 - 6000°C), very high density (outer core 9.9 - 12.2 g/cm³, inner core 12.6 - 13.0 g/cm³), and is composed mainly of iron and nickel (outer core is liquid, inner core is solid due to pressure).

Answer:

The Earth's crust has low temperature (surface - a few hundred degrees Celsius in some areas), low density (2.7 - 3.3 g/cm³), and is composed of silicate rocks. The mantle has higher temperature (500 - 4000°C), higher density (3.3 - 5.7 g/cm³), and is composed of silicate minerals. The core has extremely high temperature (4000 - 6000°C), very high density (9.9 - 13.0 g/cm³), and is composed of iron and nickel (outer core liquid, inner core solid).
