Answer: Option (3)
Explanation: Mid oceanic ridge is a direct evidence supporting the plate tectonic movement. The mid oceanic ridge is created where the two plates moves apart from one another, thereby thinning the crust and slowly rises up due to the force exerted by the uprising hot molten magma.
This is the region along which new materials are added to the crust and are considered to be the youngest. Here the at the sea floor, the amount of sediment is comparatively less than it is in the continent.
Hence, the correct answer is option (3).
The plate tectonics theory suggests that the earth's outer crust is separated into plates and move in the molten upper portion of the mantle known as the asthenosphere.
The correct answer is:
Option C. The seafloor has less sediment and is youngest at mid-ocean ridges.
The evidence of plate tectonic is:
1. The mid-oceanic ridge is direct evidence that supports the movement of tectonic plates. The ridge was created when the two plates moved apart from each other and result in the thinning of the crust.
2. The site or region at which the new substances are added is the youngest. The seafloor consists of the fewer amount of sediments than its continent.
Thus, the correct option is C.
