If this is a test question, beware! The most common answer served up by public education would be 'igneous rock'. However, the bulk of crustal rock is metamorophic. The reason for this is fairly simple: rock metamorphoses at higher temperature and pressure, both of which increase significantly with depth from the surface. Since oceanic crustal rock is on average 5 miles in depth, and continental crust is on average 30 miles in depth, the bulk of the crustal rock is exposed to great pressures and temperatures. When it is written that oceanic crust is mainly basalt, an igneous rock, and continental crust is mainly granite, also an igneous rock, it is mainly in reference to their chemical composition, not their classification by type. Warning: be prepared to back up your 'metamorphic' answer.
These thin layers are called sedimentary rocks, which are formed from the accumulation and compression of sediments over time. Sedimentary rocks are one of the three main types of rocks found on Earth's surface, along with igneous and metamorphic rocks.
Oceanic Crust
The Earth's main three parts are the crust (outermost layer), mantle (middle layer), and core (innermost layer). The crust is made up of solid rock and is divided into continental and oceanic crust. The mantle is a semi-solid layer composed of silicate rocks, while the core consists mainly of iron and nickel.
The Earth's crust is primarily composed of three types of rocks: igneous, sedimentary, and metamorphic. Igneous rocks are formed from the cooling and solidification of molten magma. Sedimentary rocks are formed from the accumulation and cementation of sediment particles. Metamorphic rocks are formed from the alteration of existing rocks due to heat and pressure.
The three main levels of the Earth are the core, mantle, and crust. The core is divided into the inner core and outer core, the mantle is located between the core and crust, and the crust is the outermost layer where we live.
Faults are surfaces along the earths crust in which rocks have been fractured and displaced. There are three types of faults: strike-slip, normal and reverse.

Erosian, weathering.
The Earth's crust does have sedimentary rocks in it's structure - limestone, slate, chalk, are three examples of commonly found sedimentary rocks.
Oceanic Crust
The lithosphere consists of the crust and upper mantle.
The three parts that make up the Earths mantle are the crust, core, and mantle.
