Explanation:

Since you've provided a set of questions related to plate tectonics (which falls under the Natural Science discipline, specifically in the subfield of Geography or Geology, but Geography is listed in the provided subfields for Natural Science), here's an example of answering one of them (let's pick question 1: "Explain the theory of plate tectonics") using the Answer-Explanation Format:

The theory of plate tectonics states that the Earth's lithosphere (the rigid outer layer) is divided into several large and small plates. These plates float on the semi - fluid asthenosphere. The plates move relative to each other due to convection currents in the mantle. This movement leads to various geological phenomena such as earthquakes, volcanic eruptions, and the formation of mountain ranges, ocean basins, and rift valleys. The interactions at plate boundaries (divergent, convergent, and transform) drive these geological processes.

Answer:

The theory of plate tectonics holds that the Earth's lithosphere is split into multiple rigid plates that move atop the asthenosphere. Mantle convection currents drive plate motion, causing geological activity (earthquakes, volcanoes, mountain/rift formation) at plate boundaries (divergent, convergent, transform).
