The dust falls from the atmosphere over the ocean, sinks through the water column and ends up as sediments on the ocean floor.
What else can I help you with?
Are volcanic rocks sedimentary?
No. Volcanic rocks are igneous (although not all igneous rocks are volcanic). Sedimentary rocks are made of sediment naturally cemented together. However, volcanic (or extrusive igneous) rocks can be eroded into sediment, which can be cemented, compacted, or otherwise become sedimentary rock such as sandstone or conglomerate. It is then not considered igneous.
Where does the sediment end up?
Sediment can end up in various places such as riverbeds, lakes, oceans, or on land. It is often deposited in layers over time, where it may become compacted and cemented together to form sedimentary rocks.
How can subsidence lead to the formation of sedimentary rocks?
When the ground subsides it can become lower than the surrounding terrain, forming a basin. Since water, which carries sediment, flows downhill, sediment will collects in these basins. If enough sediment collects, compaction and cementation will turn it into sedimentary rock.
How does volcanic dust become sediment in the deep ocean basin?
The dust falls from the atmosphere over the ocean, sinks through the water column and ends up as sediments on the ocean floor.
Does sediment become reworked?
Yes.
The greater the time that stream sediment is transportedthe greater the probability that the sediment will become more what?
The greater the time that stream sediment is transported, the greater the probability that the sediment will become more rounded and well-rounded due to abrasion and attrition processes.
What does coral become when it is buried by sediment?
a potato
Can an ocean trench become a volcanic island?
An ocean trench does not become a volcanic island, however volcanic islands often form near ocean trenches.
What sediment is compacted to form shale?
Shale is formed from the compaction and cementation of fine-grained silt and clay particles. These particles are typically compacted in low energy environments such as deep ocean basins or lake bottoms, where they settle slowly over time and become lithified into shale.
Packed down as in sediment that becomes rock?
When sediment is deposited in layers and undergoes compaction due to the weight of overlying sediments, it squeezes out water and air, causing the sediment grains to become tightly packed. With time and pressure, this compacted sediment can undergo lithification to become sedimentary rock, such as sandstone or shale.
What does slate become after sediment deposition?
Slate becomes schist
How does igneous rock change into a methaporphic rock then a sedimentary rock?
An igneous rock is formed with volcanic activity- magma or lava. This rock would then undergo extreme heat and/or pressure to become a metamorphic rock. This rock would then weather and erode to become sediment. This sediment would be deposited in an area, compacted when other sediment settles on top of it, and cemented when dissolved minerals crystallize and glue particles of sediment together. That process of weathering/erosion, deposition, compaction, and cementation would form a sedimentary rock. Hope this helps! This information is very reliable. It came straight from my darling textbook, Interactive Science for Indiana- Grade 7.
