Answer:
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, <u>the exposed rock unit in that area dips towards the South and the strike direction of this rock is the East-west direction.</u>
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.
The latitude of the Antarctic Circle is roughly 66.5 degrees South.
There is one point on the Antarctic Circle at every possible longitude.
I can help if you tell us the the question! :)
