The Pacific Coast of the US.
I might be wrong but what i can gather a hard coastline is a coastline that is surrounded by hard resistant rock like limestone. By being surrounded by hard rock it is more resistant to wave power which means that it will erode at a much slower rate. Hope this helped:)!!

As a coastline gets older, it may experience erosion caused by natural processes such as wave action, weathering, and sea level rise. This can lead to changes in the shape and form of the coastline, including the formation of cliffs, beaches, and other coastal landforms. Additionally, sediment deposition and tectonic activity may also influence the evolution of an older coastline over time.
Two landforms associated with wave action are sea cliffs, which are steep rock faces created by the constant pounding of waves against the coastline, and sea caves, which are hollowed-out caves formed by the erosion of rock by wave action.
The top of a tsunami wave is called the crest. It represents the highest point of the wave as it approaches the coastline.
Sea cliffs: High vertical cliffs formed by the erosion caused by waves hitting the coastline. Sea caves: Caves formed by wave action eroding the rock along the coastline. Headlands: High points of land that jut out into the sea, formed by differential erosion from wave action. Sea stacks: Isolated columns or pillars of rock that are left standing in the sea after the collapse of a headland. Wave-cut platforms: Flat areas at the base of sea cliffs formed by wave erosion and deposition of eroded material.
A wave-cut platform forms when the continuous erosion of coastal cliffs by wave action causes them to retreat inland. As the waves wear away the base of the cliffs, a flat and relatively smooth surface is left behind, known as a wave-cut platform. This platform is typically located at the base of the cliffs and is constantly shaped by the erosive power of the waves.
Wave-cut platforms are formed through erosion by the action of waves pounding against the coastline. As the waves erode the base of the cliffs, a gently sloping platform is created over time.
Wave erosion is the process by which waves wear away or erode the coastline or shoreline, typically through the action of hydraulic pressure, abrasion, and corrosion. This erosion can result in the formation of sea cliffs, sea caves, and sea stacks over time.
Waves cause erosion by carrying and moving sediments along the coastline. The force of the waves can gradually break down and wear away rocks and cliffs, leading to erosion of the coastline over time.
Wave erosion is caused by the constant force of waves hitting the coastline, wearing away the land through processes like hydraulic action, abrasion, and attrition. As the waves break against the shore, they can erode and shape the coastline over time, leading to the formation of features like sea cliffs, sea caves, and sea stacks.
Waves shape a beach by eroding the shore in some places and building it up in others. ♥

They are good because they stop the sea from eroding the coastline.

Wave erosion creates sea cliffs, which are steep rock faces formed by the continual pounding of waves against the coastline. It also forms sea caves, which are hollowed-out areas in the rock where waves have worn away softer rock layers.
