Learn the various meanings and uses of the word crust, from the hardened exterior of bread to the outer part of a planet. See synonyms, examples, etymology, and related phrases of crust.
In geology, the crust is the outermost solid shell of a planet, dwarf planet, or natural satellite. It is usually distinguished from the underlying mantle by its chemical makeup; however, in the case of icy satellites, it may be distinguished based on its phase (solid crust vs. liquid mantle).
Jan 25, 2019 · Learn about the Earth's crust, the thin layer of rock that forms the outermost solid shell of our planet. Discover the differences between oceanic and continental crust, how they are created and destroyed by plate tectonics, and what minerals and elements they contain.

Learn the meaning of crust as a hard outer covering of something, such as a pie or the earth, or the outside layer of a loaf of bread. See examples of crust in sentences and find translations in different languages.
Earth’s outermost, rigid, rocky layer is called the crust. It is composed of low-density, easily melted rocks; the continental crust is predominantly granitic rock (see granite), while composition of the oceanic crust corresponds mainly to that of basalt and gabbro.
Plates in the crust of Earth. Earth's crust is its thick outer shell of rock, referring to less than one percent of the planet's radius and volume. It is the top component of the lithosphere, a division of Earth's layers that includes the crust and the upper part of the mantle.
