The solid outer zone of the Earth is the lithosphere. The lithosphere is made up of the upper layer of the mantle and the crust of the Earth.

The lithosphere is made up of the Earth's crust and the uppermost part of the mantle. It is divided into several rigid tectonic plates that float on the semi-fluid asthenosphere below. This outer shell of the Earth is where you'll find continents, oceans, and most geological activity.
The lithosphere is composed of the oceanic and continental crusts, along with the attached hard, brittle rock of the uppermost mantle.
The crust and the upper mantle are a geological part of the earth called the lithosphere. There are 2 parts of the lithosphere: the oceanic lithosphere, which is made up of land underneath water, and the continental lithosphere, which is the the part made of just land. The lithosphere lies on top of the asthenosphere. The lithosphere is made up of tectonic plates, which are pieces of land floating on the lithosphere.
The lithosphere is made up of the Earth's crust and the upper part of the mantle. It is a rigid outer layer that includes the solid landmasses and oceanic crust.
Lithosphere
The lithosphere is made up of the Earth's solid outer layer, including the crust and the upper portion of the mantle. It is composed of various types of rocks and minerals, and it is broken into tectonic plates that float on the semi-fluid asthenosphere below.
Both the crust and the upper mantle are solid layers of the Earth's lithosphere. However, the crust is more brittle and less dense than the mantle. Additionally, the crust is composed primarily of oxygen and silicon (silicate minerals) whereas the mantle contains more iron and magnesium.
