Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The youngest rocks on the seafloor are most likely found____
A
closest to a mid-ocean ridge
B
farthest from a mid-ocean ridge
C
near the coastlines
D
closest to a deep sea trench
Explanation: 

Detailed explanation-1: -This hot magma forced up and out at mid-ocean ridges produces seafloor at divergent boundaries. This process explains the formation of underwater mountain ranges. The fact that the youngest rocks are located at the mid-ocean ridges is evidence for seafloor spreading.

Detailed explanation-2: -Scientists found that the youngest rocks are located at the mid-ocean ridges. The ages of the rocks become increasingly older in samples obtained farther from the ridges, adding to the evidence for seafloor spreading.

Detailed explanation-3: -The material that erupts at spreading centers along the mid-ocean ridge is primarily basalt, the most common rock on Earth.

Detailed explanation-4: -The newest, thinnest crust on Earth is located near the center of mid-ocean ridge-the actual site of seafloor spreading. The age, density, and thickness of oceanic crust increases with distance from the mid-ocean ridge.

Detailed explanation-5: -The youngest seafloor rocks can be found on mid-ocean ridges, which form part of the ocean crust. Mid-ocean ridges are dynamic geographic features located in places where the Earth’s plates are pulling away from one another; they are continually producing new rocks.
