Mantle (geology)

<p>
A mantle is a layer inside a <a href="/facts/Planetary_body/rbPjE6Bx">planetary body</a> bounded below by a <a href="/facts/Planetary_core/LyQ7DbAl">core</a> and above by a <a href="/facts/Crust_(geology)/FYG1kP4F">crust</a>. Mantles are made of <a href="/facts/Rock_(geology)/FXCJkmop">rock</a> or <a href="/facts/Volatile_(astrogeology)/yYCe49qX">ices</a>, and are generally the largest and most massive layer of the planetary body. Mantles are characteristic of planetary bodies that have undergone <a href="/facts/Planetary_differentiation/fvjC1107">differentiation</a> by <a href="/facts/Density/92p6hh9I">density</a>.  All <a href="/facts/Terrestrial_planet/jpMC1ULt">terrestrial planets</a> (including <a href="/facts/Earth/HLLmDfj0">Earth</a>), half of the <a href="/facts/Giant_planets/PjSfFuUF">giant planets</a>, specifically <a href="/facts/Ice_giant/mJ4YTuup">ice giants</a>, a number of <a href="/facts/Asteroid/g7Ulr1VB">asteroids</a>, and some planetary <a href="/facts/Natural_satellite/AE4KQKbq">moons</a> have mantles.
