30.Compare the Little Rock advection pattern to that of Oklahoma City, just north of the frontal boundary. The wind flows and air mass advection patterns on opposite sides of the developing low-pressure center displayed air flow advection patterns, consistent with the circulation expected around a low-pressure center.

OPPOSING

Explanation:

Comparing the Little Rock advection pattern to that of Oklahoma City, just north of the frontal boundary, it is easy to conclude that since the wind flows and air mass advection patterns on opposite sides of the developing low-pressure center, OPPOSING air flow advection patterns that is consistent with the circulation expected around a low-pressure center would be displayed.

answer; gravity pulls glaciers down hill and as glaciers flow it pick up rocks and soil;
