2-1. point a is at elevation 2690 feet and is located 520 feet due north of point b which is at elevation 2220 feet. point c is at elevation 2340 feet and is located 250 feet n35°e of point b. what are the strike and dip of a unit whose upper surface was observed at each of these points?

In the given topography, point A is the northern side at a height of 2690 feet. B is at a height of 2220 feet and location C has a height of 2340 feet. A and B are separated by a horizontal distance of 520 feet, B and C are separated by a horizontal distance of 250 feet and C is located at N35°E of point B.

From the above data, we can demarcate the topography of the area. The area is inclined towards the southern side as when we move from point A to C and C to A the elevation gradually decreases.

Thus, the exposed rock unit in that area dips towards the South and the strike direction of this rock is the East-west direction.

Dip is defined as the angle made by a rock bed with respect to a horizontal line and strike refers to the direction of the line that is formed due to the intersection between a rock surface and a horizontal plane.

Dip and strike always perpendicular to one another.
