* Igneous Rocks: These rocks are formed from the cooling and solidification of magma (molten rock) or lava. Examples include granite, basalt, and obsidian.

* Metamorphic Rocks: These rocks are formed when existing igneous or sedimentary rocks are transformed by heat, pressure, or chemical reactions. Examples include marble, slate, and gneiss.

While sedimentary rocks are found on the Earth's surface, they are not considered part of the lithosphere. The lithosphere is the rigid outer layer of the Earth, and sedimentary rocks are typically found in the uppermost layers of the Earth's crust.

It's important to note that the lithosphere is broken into large plates called tectonic plates, which are constantly moving and interacting with each other. These interactions cause earthquakes, volcanoes, and mountain formation.
