A

a geological landform consisting of a steep and often vertical column or columns of rock in the sea near a coast

18
Q

sea arches

A

formed when a cave continues to be eroded and expanded until it cuts right through a headland.

19
Q

sea caves

A

a type of cave formed primarily by the wave action of the sea.

20
Q

wave-cut terraces

A

shore platform, coastal bench, or wave-cut cliff is the narrow flat area often found at the base of a sea cliff or along the shoreline of a lake, bay, or sea that was created by erosion.

21
Q

headlands

A

a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water.

22
Q

beach

A

a strip of land covered with sand, pebbles, or small stones at the edge of a body of water, especially by the ocean between high- and low-water marks.

23
Q

glacier

A

a persistent body of dense ice that is constantly moving under its own weight.

24
Q

glacial drift

A

A general term applied to all rock material (clay, silt, sand, gravel, boulders) transported by a glacier and deposited directly by or from the ice, or by running water emanating from a glacier.

25
Q

till

A

up to (the point in time or the event mentioned); until.

26
Q

stratified drift

A
