Which area is the low-tide area of the beach?

Explanation:
Understanding how beach zones relate to tides helps identify the low-tide area. The foreshore is the stretch of beach that lies between the high-tide line and the low-tide line. It’s the zone that is repeatedly covered by seawater as tides rise and fall, and it becomes visible when the water recedes to low tide. The berm is a raised ridge near the high-tide line formed by wave action, so it’s associated with higher tide levels rather than the low-tide exposure. The beach face is the sloped surface of the beach below the berm where waves run up and down, a dynamic surface not defined by the low-tide boundary. The swash zone refers to the area where waves surge up and then run back down, overlapping with the foreshore but not naming the entire low-tide area. So the low-tide area is the foreshore.
