What is the 4th event to take place in the grand canyon's geologic history? question 6 options: the shinumo quartzite was deposited in a beach environment. dox sandstone is deposited in a beach environment igneous intrusion. deposition of the bass limestone in a shallow marine environment

The fourth event took place in the "Grand Canyon's" geologic history was "Dox Sandstone is deposited in a beach environment".

Option: B

Explanation:

The geological history of Grand Canyon located in Arizona, USA and involve full-sequenced rock studies on Earth. This arrangement is studied in the form of “ Unkar Group”, involve a layer of sedimentary rock named as “Stratum” from Proterozoic age which is branched into five geologic formations. This process is arranged in the following increasing order: Bass formation > Hakatai Shale > Shinumo Quartzite > Dox Formation > Cardenas Basalt. Here Dox formation is 4th portion which took place in Grand Canyon’s origination, which is a sandstone from Mesoproterozoic rock.

i would expect light rain in pittsburgh throughout the following 24 to 48 hours. the lower/falling weights in urban areas toward the west demonstrate that a low weight framework is moving from west to east toward pittsburgh. low weight frameworks are ordinarily connected with precipitation. the way that you don't see a major drop in temperature in the more western urban areas demonstrates the low weight framework is moving with a warm front, so just light rain would be normal. substantial downpours or progressively vicious climate is just typically connected with chilly fronts, where the warm air is pushed up and over a cool front quickly. this quickly rising air (convection) is what gives you heavier torrential downpours, and other conceivably serious weather conditions.
