Which statement best explains the theory of plate tectonics?
If necessary, review the Introduction to "Prove they move".
options:
(1)The theory of plate tectonics explains continents rapidly change places from one hemisphere to another when Earth’s magnetic field reverses.

(2)The theory of plate tectonics explains how the same plants and animals are on different continents which is supported by glossopteris plant fossils and Lystrosaurus reptile fossils.

(3)The theory of plate tectonics explains how continents drifts (through the process of seafloor spreading) which is supported by young ocean rocks, earthquakes and volcanoes occurring at plate boundaries and magnetism in rocks changing.

(4)The theory of plate tectonics lead to Alfred Wegener's theory of continental drift which is supported by both fossil evidence (similar species living on different continents) and rock evidence (continents fitting together, similar rocks on different continents and similar sediments and glacier scratches on different continents.
all you got to do is click any one you can have any number of chances so how is so hard btw it dose not count towards your grade but here the answer . 1 Earth’s crust is composed of rock plates that float on top of the mantle. 2 the mid-Atlantic Ridge splitting Iceland . 3 Volcanoes are found on its rim. 4They release materials that form fertile soils. 5 disturbance on the ocean floor. 6 the breakdown of rock and sediments into smaller pieces. 7 It forms from the remains of plants and animals. 8They both help reduce erosion from water runoff. 9 It is a chemical weathering process in which oxygen combines with substances in rock. 10 frost wedging. 11in folded mountains. 12 It is a rock with pores.
this is hard and i only have 48 hours to do this :(

To understand the theory of plate tectonics, one must consider various pieces of evidence. The process of seafloor spreading explains how new crust is formed at mid-ocean ridges, causing the plates to move away from each other. This explains the drifting of continents over time. This idea is supported by the presence of young ocean rocks, which are found closer to the mid-ocean ridges and get older as they move away.
The occurrence of earthquakes and volcanoes is also crucial in understanding plate tectonics. These geological activities are concentrated at plate boundaries, where the plates interact and create stress along their edges. This interaction leads to seismic events and volcanic eruptions, providing evidence for the movement of plates.
Furthermore, changes in the Earth's magnetic field recorded in rocks provide support for plate tectonics. As molten rock cools and solidifies, it preserves the orientation of the Earth's magnetic field at that time. By studying these magnetic rocks, scientists have discovered that the Earth's magnetic field has reversed in the past. This information helps explain how continents can rapidly change places when the magnetic field reverses.
In summary, the theory of plate tectonics explains how continents drift over time, supported by evidence such as seafloor spreading, earthquakes and volcanoes at plate boundaries, and changes in the Earth's magnetism recorded in rocks.
