Question: Which of the following DOES NOT provide evidence that continents move by plate tectonics?

Options:
- Volcanic hot spot tracks
- GPS measurements of plate motion
- Symmetric magnetic stripes on each side of mid ocean ridges
- Using seismic waves to determine that the Earth's outer core is liquid

Analysis:
Option 1: Volcanic hot spot tracks. These tracks form as a tectonic plate moves over a stationary hotspot in the mantle, producing a chain of volcanoes that records the direction and speed of plate movement. This is classic evidence for plate tectonics and plate motion, so this option supports the idea rather than contradicting it.

Option 2: GPS measurements of plate motion. Modern GPS technology directly measures the movement of tectonic plates with precise station coordinates over time. This is a direct, contemporary demonstration of plate motion and hence evidence for plate tectonics.

Option 3: Symmetric magnetic stripes on each side of mid ocean ridges. The alternating symmetric patterns of magnetic polarity in newly formed ocean floor sediments record seafloor spreading at mid-ocean ridges, a hallmark of plate tectonics. This strongly supports the concept.

Option 4: Using seismic waves to determine that the Earth's outer core is liquid. Seismic studies revealing the liquid outer core pertain to Earth's internal structure and dynamics, not to the movement of tectonic plates on the surface. This finding does not provide evidence that continents move by plate tectonics; it addresses a different geophysical property.

Overall, three options (hot spot tracks, GPS plate motion, and magnetic stripes) are well-established evidence for plate tectonics, while the fourth pertains to core properties and is not evidence of plate movement.
