The rigid blocks of Earth's crust and upper mantle are known as tectonic plates. These plates float on the semi-fluid asthenosphere beneath them and interact with each other, causing phenomena like earthquakes, volcanic activity, and mountain building. The movement of these plates is responsible for shaping the Earth's surface through processes like subduction, spreading, and collision.
The plate tectonic theory states that Earth's lithosphere is divided into several large, rigid plates that move and interact with each other at their boundaries. These interactions result in processes such as earthquakes, volcanic eruptions, and mountain formation. The theory provides a comprehensive explanation for many geological phenomena and continues to be a fundamental concept in understanding the Earth's dynamic nature.
There are a number of websites that provide maps or diagrams showing the major tectonic plates. Perhaps one of the best is that produced by the US Geological Survey. Please see the related link.
Tsunamis can be triggered by undersea earthquakes, especially those near subduction zones where tectonic plates collide. Volcanic activity can also be linked to earthquakes when magma movement or pressure causes the surrounding rock to fracture and release seismic energy.
I need help
i need help with my homework and this is a question and i cant find it in the book
The wording you used didn't make much sense. I'll try to answer it to the best of my ability. Common land forms caused by the movement of plate tectonics include volcanoes and mountains. Sudden tectonic is what causes earthquakes.
Earth's plates are made up of the rigid outer layer of the Earth's surface, known as the lithosphere. The lithosphere is composed of the Earth's crust and the uppermost part of the mantle. These plates float on the semi-fluid asthenosphere layer beneath them, which allows for the movement of tectonic plates.
The plate tectonic theory states that new Earth crust is being formed while old crust descends back into the mantle. Uneven heating in the mantle causes convection which keeps the crust in motion. The constant movement of Earth's plates are the result of the three types of boundaries, divergent, convergent, and transform, and the convection in the mantle.

advection
The speed at which tectonic plates move is best measured in centimeters per year. This measurement is used to determine the rate at which continents are shifting and the resulting impacts on geological processes.

The best evidence of crustal movement is seismic activity, where earthquakes occur due to the shifting of tectonic plates underneath the Earth's surface. Geological features like mountains, rift valleys, and ocean trenches also provide evidence of crustal movement over long periods of time. Additionally, the alignment of magnetic minerals in rocks recording the past movements of the Earth's magnetic poles is another indicator of crustal movement.
A convergent plate boundary diagram best represents the type of plate movement that results in mountain building. This occurs when two tectonic plates collide, with one being forced beneath the other in a process known as subduction. The intense pressure and heat generated during this collision lead to the formation of mountain ranges.

The Jordan Fault is a transform plate boundary, where two tectonic plates slide past each other horizontally. This boundary is associated with significant seismic activity due to the stress caused by the plates' movement.
