Question

which statement is true of a mid - ocean ridge? *
the age of the rock gets younger the farther from the ridge one travels
sediments deposited near the ridge are thicker and older than sediments farther from the ridge
as the plates of the ridge separate, it triggers decompression melting in the mantle
a thin spot at the center of a tectonic plate generates a large magma plume
3 points

Explanation:

Mid - ocean ridges are divergent plate boundaries. New oceanic crust is formed at the ridge. As the crust moves away from the ridge (spreading), sediments start to accumulate on it. The longer the crust has been away from the ridge (i.e., the farther it is from the ridge), the more time there is for sediments to deposit. So sediments deposited near the ridge are thinner and younger, while sediments farther from the ridge are thicker and older.

Answer:

Sediments deposited near the ridge are thinner and older than sediments farther from the ridge.
