Question

During the Mid-to Late Paleozoic westward subduction

a. shoved the Antler Arc up over the N. American continental margin
b. pushed the N. American continent margin above sea level
c. decreased the volume of detrital sediments into the area of the continental shelf
d. shoved the N. American continental margin up over the Antler Arc

Answer 1

Final Answer:

a. Shoved the Antler Arc up over the N. American continental margin.

Step-by-step explanation:

During the Mid-to-Late Paleozoic, westward subduction had the effect of shoving the Antler Arc up over the North American continental margin. This geological process involved the convergence of tectonic plates, with the subduction zone causing uplift and deformation of the Earth's crust.

Option a is correct because the Antler Arc, a geological feature, was pushed upward over the North American continental margin as a result of this subduction activity. This process contributed to the formation of mountainous regions and complex geological structures in the area.

The other options (b, c, d) are not accurate descriptions of the effects of westward subduction during the Mid-to-Late Paleozoic. Therefore, option a is the correct and relevant choice.

Answer 2

During the Mid-to Late Paleozoic, westward subduction shoved the Antler Arc up over the North American continental margin (a).

Therefore, correct answer is a. shoved the Antler Arc up over the N. American continental margin.

Step-by-step explanation:

Westward subduction during the Mid-to Late Paleozoic period had a profound impact on the geological features of the region. Specifically, option (a) is the correct answer. This means that the Antler Arc, a geological feature formed by the convergence of tectonic plates, was pushed up and over the North American continental margin.

The process of subduction involves one tectonic plate sinking beneath another, and in this case, it led to the uplifting of the Antler Arc over the North American continental margin.

Therefore, correct answer is a. shoved the Antler Arc up over the N. American continental margin.
