Answers & Comments
1.True
Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles. ... Glacial moraine deposits and till are ice-transported sediments.
2.True
3.True
Soil formation begins with the physical and chemical breakdown of the earth's rocks, caused by atmospheric agents. These processes, known as weathering, chip away rock fragments and thus modify its inherent physical and chemical characteristics.
4.True
Quarrying operations can adversely alter pre-existing ecosystems, and change hydrogeological and hydrological regimes.Quarrying basically destroys landscape. This can lead to downstream movement, scouring, or accumulation of sediment while provoking shoreline erosion
