You come upon an outcropping of sandstone while working in the field in Southern Utah. You notice cross-beds. Which of the follo
wing would you be able to determine about this deposit, just from looking at it? Group of answer choices A.the complete mineral composition of the sandstone B.the direction of the wind at the time it was deposited C.the tectonic history of the deposit D.the origin of the sand in the deposit
B. the direction of the wind at the time it was deposited
Explanation:
Cross beds refers to those rock beds which are formed due to the deposition of bed forms such as dunes. These cross beds are the group of inclined layer which is formed due to the flowing of water or wind. These rock beds represents the movement or direction of wind and water at the time of deposition and as a result cross beds are formed. So we can say that cross beds were formed due to the direction of wind.
