Question

Deposition occurs when the sediment, a mixture of rock and soil created by weathering, is eroded and transported to another location. Once it ceases movement and begins to settle, compaction initiates, facilitated by a combination of [select an answer] and the weight of additional sediment deposited above. The sediment and soil characteristics of each ecoregion in Texas are shaped by the processes of____, _____, and _____.

Answer 1

Sediment compaction occurs due to water pressure and overlying sediment weight, leading to sedimentary rock formation through processes like weathering, erosion, and deposition.

Step-by-step explanation:

Sedimentary Rocks and Ecoregion Soil Characteristics:

Deposition occurs when sediment, a mixture of rock and soil created by weathering, is transported and then settles when it ceases movement. The initiation of compaction is facilitated by a combination of water pressure and the weight of additional sediment deposited above. As this process continues, sediment becomes more compact and precipitates minerals in pore spaces, which acts as a 'glue' to cement the grains forming sedimentary rocks like conglomerate and sandstone.

The soil characteristics of each ecoregion in Texas are shaped by the processes of weathering, erosion, and deposition. Weathering breaks apart rocks into smaller particles, erosion transports these particles away, and deposition occurs when these particles settle and accumulate in a new location to ultimately become compacted and cemented into sedimentary rock formations. Clastic rocks such as sandstone are formed from particles settled from water or air, while others like limestone precipitate from solution or form from organic debris.
