Also called a shore platform, a wave-cut notch is a narrow flat area that is normally found at the base of a sea cliff or the shoreline of a sea, lake or bay. It forms by the action of waves hitting against the face of the cliff. Wave-cut notches are mostly obvious during low tides when they become visible as huge, flat rocks.Know More
Wave-cut notches are only identified when sand is moved by a storm or during low tide periods. They are formed as waves hit a cliff between the high and low tide lines. Eventually the notches grow to become caves, then are undermined by continuing wave action until the cliff collapses. Once the cliff is the same level as the beach, it becomes less possible for the sea to continue eroding the remaining rock. Given the right conditions, the continuous landward retreat and erosion of the cliff results in a flat, wide rock that looks as if the rock’s foundation has been exposed.
Wave-cut notches sometimes provide evidence about sea levels in the past. When researchers find these raised surfaces behind present-day beaches, they provide evidence of higher sea levels that existed in the geological past. Through studying fossils found in the platform or through scientific dating methods, geologists and geographers can often determine when the platform was formed.Learn more about Erosion & Weathering
A wave-cut platform is a coastal geological feature, formed when ocean waves erode the rock at the base of a cliff, leaving a protruding area at the top and a notched area below it. They are also referred to as abrasion platforms.Full Answer >
According to Livescience, the highest waves in the ocean tower at over 550 feet. They typically happen in the South China Sea's Luzon Strait, and these waves rarely break the surface of the water.Full Answer >
The top of a wave is called the crest of a wave. It is the point on the wave that has the maximum height value.Full Answer >
The third side of an isosceles triangle is called the base. The triangle has a total of three sides, and the base connects the remaining two sides, which are referred to as the legs. The two legs of the isosceles triangle must be equal in length.Full Answer >
