The presence of cross-bedded sandstone may indicate that the region where it is present was once...?

Question

a.an ocean.
b.a desert.
c.a mountain.
d.a lake.

Answer 1

Cross-bedded sandstone would have most likely formed in a desert. Cross-bedding is most characteristic of sand dunes and river deltas. In oceans or lakes, you would be more likely to find ripple marks, and sedimentary structures such as cross-bedding, ripple marks, and mud cracks are not usually formed on mountains. :)

Answer 2

Once I answer this question you will have thirty of the same answers. Oceans don't change except to advance along the coast line. Deserts don't have cross-bedded sandstone created by anything but winds and dryness. A mountain formed from the ice age and more than likely--no sandstone. A lake shows numerous levels of sandstone and years can be determined by the cross-bedded sandstone--LAKE--

Answer 3

The correct answer is (a).
More specifically cross-bedded sandstones occur in th shallow waters just off a coast.

Answer 4

in reality, any of them. Crossbedding only indicates the presence of currents (water and or air marine or non-marine) at the time of deposition. Now read your text and stop expecting us to do your homework.
