how do mountain formed? its because of the colliding pulling apart sliding past each other of tectonic plate? am i right?

what is the difference of tectonic plates with plate tectonics?

I think you are right. Tectonic plates are the actual plates themselves while plate tectonics is the science (or the name of the science) of the process.

Yes you're right.

Yes, you are correct! Mountains are generally formed as a result of the interaction between tectonic plates. Tectonic plates are large, rigid pieces of Earth's lithosphere (the outermost layer of the Earth) that are constantly moving. These plates can either be colliding with each other, pulling apart, or sliding past each other. These movements create various geological features, including mountains.

When two tectonic plates collide, the force and pressure exerted cause the crust to buckle, fold, and uplift, leading to the formation of mountains. This type of mountain formation is known as "fold mountains" and can be seen in the Himalayas.

On the other hand, when tectonic plates pull apart, this can result in the formation of mountains through a process called "fault-block mountains." In this case, as the plates separate, blocks of crust along the fault lines are uplifted, forming mountains. The Sierra Nevada range in the United States is an example of fault-block mountains.

Regarding your second question, "tectonic plates" refer to the large pieces of Earth's lithosphere, whereas "plate tectonics" is the scientific theory that explains the movement and interaction of these plates. Plate tectonics describes how the Earth's lithosphere is divided into several plates and how they interact with each other, leading to various geological phenomena like earthquakes, volcanic activity, and mountain formation.

In summary, tectonic plates are the large pieces of Earth's lithosphere, and the movement and interactions between these plates, as explained by plate tectonics, are responsible for the formation of mountains.
