Which of the following is NOT evidence that tectonic plates move?
Sea floor spreading
Mountain ranges
Earthquakes
Radiation in Earth's core**
I agree.
Radiation in Earth's core is NOT evidence that tectonic plates move.
To determine which of the options is NOT evidence for the movement of tectonic plates, we must understand what each of the options represents and how it relates to plate tectonics.
1. Sea floor spreading: This phenomenon occurs at mid-ocean ridges, where new crust is formed as magma rises to the surface and solidifies, pushing older crust away from the ridge. This spreading of the oceanic crust is evidence of plate movement as new crust is continually created.
2. Mountain ranges: Mountains are often formed when tectonic plates collide. The collision of two plates can cause the crust to fold, uplift, and create large mountain ranges such as the Himalayas or the Andes. This indicates the movement and interaction of plates.
3. Earthquakes: Earthquakes are a direct result of the movement of tectonic plates. When stress builds up along plate boundaries and is suddenly released, it causes seismic waves that result in an earthquake. The occurrence of earthquakes along plate boundaries shows that the plates are actively moving.
4. Radiation in Earth's core: This option is not evidence of plate movement. The radiation in Earth's core refers to the heat generated by the decay of radioactive elements within the Earth's interior. While this radiation is an important factor in Earth's geologic processes, it is not directly related to the movement of tectonic plates.
In summary, sea floor spreading, mountain ranges, and earthquakes are all evidence of plate tectonic movement. However, the radiation in Earth's core is not evidence for plate tectonic movement.
