The Earth's crust is divided into several large tectonic plates, with around 7 major plates and several smaller ones. These plates float on the semi-fluid upper mantle and interact at their boundaries, where most of the Earth's seismic activity occurs.
Tectonic or lithospheric plates.
The Earth's crust is divided into several major and minor tectonic plates. There are around seven major plates, including the African Plate, the Pacific Plate, and the Eurasian Plate, along with numerous smaller plates. These plates float on the semi-fluid asthenosphere and interact with each other along their boundaries, leading to various geological phenomena.
No, the earth's crust is made up of several large pieces known as tectonic plates. These plates float on the semi-fluid layer beneath them and interact with each other, causing movements like earthquakes and volcanic eruptions.
Earth's crust is divided into a series of large and small plates, known as tectonic plates. There are about 7 major plates (e.g., the Pacific Plate, North American Plate) and several minor plates that make up the Earth's crust.

there are 8 plates
The Earth's crust is divided into several large and small tectonic plates, typically numbering around 15 major plates and numerous smaller ones. These plates float on the semi-fluid asthenosphere beneath them and interact at their boundaries, leading to geological activity such as earthquakes and volcanic eruptions. The major plates include the Pacific Plate, North American Plate, Eurasian Plate, and others.
The crust is about 40 kilometers thick in many places. The crust is the coldest layer of all the layers of earth. The crust makes up less than 1% of the earths mass. The crust is mainly made up of silicon,aluminum,calcium,sodium, and potassium.
