The earliest known rocks on Earth, dating back around 4 billion years, belong to the Archean Eon. These rocks provide evidence of the formation of the Earth's crust and the beginning of plate tectonics.
Yes, the singular form is normally plate tectonic or tectonic plate so the plural would be plate tectonics or tectonic plates. Dumb crap.
Fault lines.
No. Mars does not have plate tectonics. The volcanoes on Mars are the result of hot spots.
Plate Tectonics
Hot spots caused by mantle plumes create new igneous rocks. Plate tectonics causes old crust to be destroyed and new crust to form which also forms new igneous rocks. Plate tectonics is also responsible for metamorphism which creates new metamorphic rocks. Sedimentary rocks are created by the weathering, erosion, and later lithification of of pre-existing rocks (e.g. sandstone). Sedimentary rocks can also precipitate from aqueous solutions (e.g. Halite). Forces: plate tectonics, weathering, erosion, precipitation
Earth's magnetic pole reversals are recorded in rocks as they cool and solidify. When rocks form, they preserve the orientation of Earth's magnetic field at that time. By studying the magnetic alignment of rocks on the ocean floor, scientists have discovered patterns that support the theory of plate tectonics, such as the symmetrical magnetic striping on either side of mid-ocean ridges.

On Earth, plate tectonics and erosion have removed all of the rock that was originally surface rock, exposing the underlying crustal rocks and releasing magma to form new igneous formations. On the Moon, neither process is at work. Meteoroids striking the Moon have piled the rocks up and created a layer of fine powder there, but the exterior rocks are still those that formed shortly after the Moon itself.
A scientist who studies rocks and the Earth's structure is called a geologist. Geologists analyze the composition, structure, and history of rocks to understand processes like plate tectonics and Earth's geological history. They also study how rocks form and change over time to learn more about the Earth's past and present.
I can't find it in my packet either.
Rocks lock in their magnetism when they cool.
