Answer:
The man-made features that are typically parallel to the shore are:
A) Piers
C) Groins
Explanation:
1. Man-made features are structures built by humans to modify or enhance the natural environment.
2. When it comes to coastal areas, several types of man-made features are commonly constructed.
3. Piers are structures that extend from the shore into the water and are typically parallel to the shore.
4. Piers is often used as a platform for recreational activities, fishing, or docking boats.
5. They are built perpendicular to the shoreline, extending out into the water, while running parallel to the shore.
6. Groins are another type of man-made feature that is designed to protect beaches from erosion.
7. Groins are usually built as a series of structures that run perpendicular to the shoreline.
8. However, when viewed from above, these structures appear parallel to the shore because they are constructed in a line along the beach.
9. Groins are typically built to trap sand and prevent it from being carried away by longshore currents, which helps to maintain and replenish the beach.
10. Breakwaters and jetties, on the other hand, are not typically parallel to the shore.
11. Breakwaters are structures built offshore to protect harbors or shorelines from wave action.
12. They are constructed at an angle or in a curved shape to provide a barrier against waves.
13. Jetties are similar to breakwaters, but they are built to stabilize river mouths or harbor entrances.
14. Jetties are often built in pairs and are not parallel to the shore, as they are intended to redirect water currents and maintain navigation channels.
In summary, the man-made features that are typically parallel to the shore are piers and groins. These structures extend along the shoreline and serve different purposes, such as providing recreational access or preventing beach erosion.
