Tectonic movement refers to the shifting and interaction of the Earth's lithosphere, which is divided into several large and small tectonic plates. These plates float on the semi-fluid asthenosphere beneath them, and their movements can lead to geological phenomena such as earthquakes, volcanic eruptions, and the formation of mountains. Tectonic activity is driven by forces such as mantle convection, slab pull, and ridge push, which result in divergent, convergent, and transform boundaries. Understanding tectonic movements is crucial for assessing geological hazards and the Earth's dynamic processes.
they are crust and the mantle and also the core
True. Mountains can form when parts of the Earth's crust are uplifted along fault lines due to tectonic forces, such as when two tectonic plates collide or slide past each other.
about 0.003 parts per billion in the earth's crust.
The Earth's plates are composed of the lithosphere, which includes the uppermost part of the mantle and the crust. The lithosphere is broken into tectonic plates that float on the semi-fluid asthenosphere beneath them. Movement of these plates is responsible for processes like earthquakes, volcanic activity, and the formation of mountains.
There is almost no crust under Hawaii because it is under a divergent boundary or two tectonic plates pulling away from each other so magma is still rising onto or around Hawaii. So the tectonic plates are not under Hawaii and since tectonic plates make most of the crust on earth there is practically no crust under Hawaii.
Tectonic Plates
Movement of tectonic plates which are parts of the Earth's crust.
majority of valcanoes follow the edges of the tectonic plates, which are the weaker parts of earths crust, therefore volcanoes form durin the crust giving away to the pressure built up. other volcaoes form other places due to weak parts of earths crust

geosphere
The movement of a plate is typically considered uneven because plates move at different rates and in different directions. This uneven movement is driven by factors such as tectonic forces and the varying densities of different parts of the Earth's crust.
The three parts that make up the Earths mantle are the crust, core, and mantle.
The slipping or sliding surface of parts of the Earth's surface is known as a fault line. This is where movement occurs along the surface of the Earth, resulting in earthquakes.
usually mountains are created by the earths tectonic plates pushing two parts of the crust together and upwards forming a mountain, this takes 1000s of years. Mountains are also created by magma coming through the crust (which turns into a volcano)
