  2. Stack (geology) - Wikipedia

    en.wikipedia.org/wiki/Stack_(geology)

    These cracks then gradually get larger and turn into caves. If a cave wears through a headland, an arch forms. Further erosion causes the arch to collapse, leaving the pillar of hard rock standing away from the coast, the stack. Eventually, erosion will cause the stack to collapse, leaving a stump.

  3. Surf zone - Wikipedia

    Schematic representation of the shoreface profile. The surf zone or breaker zone is the nearshore part of a body of open water between the line at which the waves break and the shore.

    en.wikipedia.org/wiki/File:Time-lapse_video_of...

    A pole on the bluff, visible in the first half of the video, once supported another video camera that was aimed at the shoreline to study wave and shoreline dynamics. This video starts on June 1st at -4°C (25° F) when the bluffs are still frozen, snow is on the ground, and the winter pack ice protects the permafrost cliffs from wave attack.

  5. Erosion - Wikipedia

    en.wikipedia.org/wiki/Erosion

    Erosion and changes in the form of river banks may be measured by inserting metal rods into the bank and marking the position of the bank surface along the rods at different times. [23] Thermal erosion is the result of melting and weakening permafrost due to moving water. [24] It can occur both along rivers and at the coast.

    Wave audio or variant, may refer to: Sound, vibrations carried on acoustic waves; Acoustic wave, audio waves that carry sound.wav, waveform audio file format;

  7. Wave pounding - Wikipedia

    en.wikipedia.org/wiki/Wave_pounding

    Wave pounding is a force of erosion along coast lines. The effects of wave pounding are influenced by wave shape, ocean chemistry , rock type, and morphology of the coastal landscape. There are three different types of waves to consider in this process: spilling, plunging, and surging waves.

    However, eruptions more than kept pace with wave erosion, and by February 1964, the island had a maximum diameter of over 1,300 metres (4,265 feet). [ 5 ] The explosive phreatomagmatic eruptions caused by the easy access of water to the erupting vents threw rocks up to a kilometre (0.6 mi) away from the island, and sent ash clouds as high as 10 ...

  9. Coastal erosion - Wikipedia

    en.wikipedia.org/wiki/Coastal_erosion

    Coastal erosion may be caused by hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural. [3] On non-rocky coasts, coastal erosion results in rock formations in areas where the coastline contains rock layers or fracture zones with varying resistance to erosion.
