Along with their attached rigid uppermost mantle, they are referred to as tectonic plates.
Along with their attached rigid uppermost mantle, they are referred to as tectonic plates.
The layer of the Earth which makes up the plates is called the lithosphere. The lithosphere is composed of the continental and oceanic crusts along with the hard upper mantle.
No. The lithosphere is composed of the crust along with the uppermost rigid mantle.
Earth's mantle. These convection currents are driven by heat from the Earth's core, which causes material in the mantle to become less dense and rise, and denser material to sink. This movement of the mantle material pushes and drags the tectonic plates along with it.

The crust, along with the attached uppermost brittle mantle, is called the lithosphere. Tectonic plates are also known as lithospheric plates.

The earth's surface is broken up into many moving pieces called lithospheric plates. These consist of both continental and oceanic plates. These plates move around over millions and millions of years through a process called mantle convection. Essentially, hot magma rises, cools, and sinks due to a higher density. This creates a cycle-type motion, which moves the plates along. When plates collide, they create different types of boundaries, but that isn't necessarily important to your question.
The Earth travels along a path called the Ecliptic.
35 - 60 Kms would be the uppermost mantle, which along with the crust forms the hard, brittle lithosphere. The Mantle is a semi-molten layer.
There are many eruptions in Haiti, California and Chile, because they are all on top of what are called plate boundries. The earth is made up of many 'puzzle pieces' that carry continents on them, they float along the earth's mantle-burning hot liquid rock- and sometimes collide or rub against each other, creating the earth to shake, and the closer to a plate boundry the more you feel the movement. That's why!

All of the Earth's mantle is hot. And while some geologists believe that there are Mantle plumes (or hot spots) current evidence seems to support a view that mantle plumes do not exist. What causes magma to rise up from the lower crust and mantle is the convection of the mantle and therefore the places where most heat (and magma) is coming up to the surface is along the mid oceanic ridges.
