Question

the maps below show changes in the distribution of land and water in the mediterranean sea region that scientists believe took place over a period of 6 million years. which type of rock was precipitated from seawater as the mediterranean sea evaporated between 8 million years ago and 5.5 million years ago? a) basalt b) metaconglomerate c) rock salt d) sandstone

Explanation:

When seawater evaporates, the dissolved salts precipitate out. Rock - salt is formed by the evaporation of seawater as the salts in the water crystallize. Basalt is an igneous rock formed from the cooling of lava, metaconglomerate is a metamorphic rock, and sandstone is a sedimentary rock formed from the compaction and cementation of sand - sized grains, none of which are directly precipitated from evaporating seawater in this context.

Answer:

C. rock salt
