What type of rocks would you expect to find in a playa lake depositional environment?

A. Evaporites and claystone
B. Fossiliferous limestone
C. Poorly sorted conglomerates
D. Cross-bedded sandstone
E. Interbedded sandstones and conglomerates

Answer :

Final answer:

In a playa lake depositional environment, you would find evaporites and claystone. Evaporites are chemical sedimentary rocks that form when water evaporates, leaving behind minerals. Claystone is a type of clastic sedimentary rock composed mainly of clay particles that can accumulate in playa lakes.

Explanation:

In a playa lake depositional environment, you would expect to find evaporites and claystone.

Evaporites are chemical sedimentary rocks that form when water evaporates, leaving behind minerals such as salt or limestone. Playa lakes are shallow, temporary bodies of water that often experience high evaporation rates, making them conducive to the formation of evaporites.

Claystone, on the other hand, is a type of clastic sedimentary rock composed mainly of clay particles. Playa lakes can accumulate fine-grained sediments like clay due to their calm and stagnant water conditions.
