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.
Answer:
d. may belong to any of the three primary rock types
Explanation:
- Metamorphic rock is the transformation of any of the existing rocks through the process of metamorphism i.e associated with changes in form. When the original rocks are subject to intense heat from below. The Pressure over these rocks causes profound hearing and compaction of rocks particles and matter.
- About 12% of the earth's surface is made up of metamorphic rocks that are either derived from the igneous or sedimentary rocks based on texture, chemical, and mineral assemblage.
- Some common examples of these rocks are gneiss, slate, marble, and schist, etc that have been formed from the sedimentary processes.
Lagos ,Nigeria kinda cool
