How does igneous rock turn into sediment Rock?

Answer 1

Through weathering and erosion of the igneous rock. The igneous rock, exposed to weathering processes at the surface, breaks into smaller pieces. Erosional processes transport these pieces to a place of deposition where they build up, layer on layer. Eventually the compaction caused by the weight of the sediments above reduces the amount of space and water between particles. In this process of rock formation known as lithification, cementing minerals are formed out of the slowly disappearing fluids, which are saturated with mineral components. Once cemented together, it is now considered sedimentary rock. Quartz sandstone is an example of the resultant sedimentary rock derived from the processes described above on the igneous rock granite.

weathering errosion transportation deposition and finally cementation converts to sedimentary rock

Answer 2

Igneous rock, when exposed, will weather into smaller particles by mechanical and chemical means. Eventually the particles will be eroded and be transported by wind, water, ice, and gravity and eventually be deposited along with other sediments in a low lying area; could be the bottom of a sea, ocean or lake. As further and further sedimentation and accretion occur, the weight of overlying sediments compacts the particles, squeezing out air and water. Minerals then can bridge the gaps between particles, cementing them together into sedimentary rock.

Answer 3

Igneous rock is formed from magma that flows to the surface through volcanic activity and then hardens. Over time the igneous rock is exposed to the elements and weathering, both physical and chemical. These weathering processes break the igneous rock down into sediments that can accumulate in thick layers and then harden into sedimentary rock.

Answer 4

Erosion, and lithification will be the answer for Apex

Answer 5

By melting and then solidifying. But there may be a process of metamorphism that takes place before melting occurs.

Answer 6

Exposure and weathering, Erosion and deposition, and then Lithification and Compaction

Answer 7

By being weathered, eroded and re-deposited.

Answer 8

By erosion, deposition and cementation

Answer 9

Compaction :)

Answer 10

It melts it
