a moving portion of earths crust and upper mantle is called a ridge that's when the ocean floor has underwater volcano that erupts
Tectonic plates are floating on the magma (semi-molten rocks) of the mantle layer. Therefore, they form the crust layer of the Earth.
The lithosphere consists of the rigid outermost layer of Earth, which includes the crust and a portion of the upper mantle. It is broken into tectonic plates that float on the semi-fluid asthenosphere beneath. This layer is where most geological activity, such as earthquakes and volcanic eruptions, occurs.
The mantle is located directly beneath the Earth's crust and is approximately 1,800 miles (2,900 kilometers) thick. The boundary between the crust and the mantle is known as the Mohorovičić discontinuity or Moho.
The sphere that extends from Earth's core to Earth's crust is known as the mantle. It is a layer of solid rock that lies between the core and the crust, making up the majority of Earth's volume. The mantle is divided into the upper mantle and the lower mantle based on depth and composition.
The layer of the Earth below the crust is called the mantle. The mantle is the thickest layer of the Earth with a depth of 2,890 kilometers.
Simple- Convection in the mantle causes mantle to slowly move, and it pushes against the crust. As it does this, the tectonic plates move.

The mantle is hotter than the crust.
Most of Earth's new crust is found along mid-ocean ridges, underwater mountain ranges where tectonic plates are moving apart. This is where magma rises from the mantle to create new crust through volcanic activity.
a portion is a small amount of it

yes it does.
the mantle
the area of of earths crust that is the thickest is the mantle.
the area of of earths crust that is the thickest is the mantle.
The mantle is located right under Earth's crust.
