marine terrace, a rock terrace formed where a sea cliff, with a wave-cut platform (q.v.) before it, is raised above sea level. Such terraces are found in California , Oregon, Chile, and Gibraltar and in New Zealand and other islands of the Pacific.
Marine terraces (Fig. 3 C and D) are flat surfaces interrupting the continuity of the coastal landscape and are created by the interplay of marine erosional and depositional processes. They are usually larger in size than shore platforms (they may be up to few kilometers wide) and are often mantled by deposits of marine origin.
Marine terraces result from the interaction of two geologic processes: uplift of the land surface and the natural rise and fall of sea level over hundreds of thousands of years.
Marine Biomes. The ocean is the largest marine biome. It is a continuous body of salt water that is relatively uniform in chemical composition; it is a weak solution of mineral salts and decayed biological matter. Within the ocean, coral reefs are a second kind of marine biome.
1 sty 2021 · A marine terrace is any relatively flat, horizontal, or gently inclined surface of marine origin, bounded by a steeper ascending slope on one side and by a steeper descending slope on the opposite side.
Marine terrace terminology follows that reviewed by Muhs (2022). The most important geomorphic feature of California marine terraces, for interpretations of sea level history, is what is...
19 sie 2024 · Marine terraces are a defining geomorphological feature of the West Coast, and are dispersed along the entire extent of California’s active, uplifting coastline. Found on emergent tectonic coastal margins worldwide, marine terraces underlay much of California’s heavily developed and populated regions.
