Can igneous rock be weathered to form sediment?
Yes. Any rock can be weathered to form sediment.
How does weathering and erosion change a mountain made of solid rock?
Weathering breaks or dissolves the rock and erosion transports the resultant sediments to another location. The result is a gradual reduction in the elevation of the mountain.
How do lithogenous sediments differ from biogenous sediments?
Lithogenous sediments come from the land They result primarily from erosion by water, wind, and ice Biogenous sediments originate from organisms The particles in these sediments come from shells and hard skeletons. Although lithogenous sediments represent the largest total volume, biogenous sediments cover a greater area of sea floor
When wind blows sediment against an obstacle what does the built-up sediment result?
Wouldn't you like to know ;)
Rock can become magma again as a result of?
erosion
What is created as a result of the moving of rock and sediments?
The ultimate creation of moving rock and sediment is a sediment deposit. Sediment deposits can eventually lithify into sedimentary rock.
How does a river collect sediments?
Most sediment washes or falls into the river as a result of mass movement and runoff. Other sediment erodes from the bottom or sides of the river
Can igneous rock be weathered to form sediment?
Yes. Any rock can be weathered to form sediment.
What happenes to these sediments as they move around?
Sediments move around due to the combination of the force of gravity acting on the sediment and or the movement of the fluid in which the sediment is entrained. Movement may either be made by air, water or ice. Sediment movement in fluids occurs in water bodies as a result of water currents and tides.

Where does sea sediment Jasper come from?
Sea sediment jasper is a type of jasper that is often found near the shores of oceans, where sediments have accumulated over time. The unique patterns and colors in sea sediment jasper are a result of different minerals and compounds being deposited in the sediment layers that eventually solidify into jasper.
What is lithification in geology?
Lithification is the natural creation of sedimentary rock through the processes of compaction and cementation of sediments. The compaction usually occurs as a result of the crushing weight of overlying sediments above, expelling water and air from between the pore spaces of the individual sediment particles. As the water is squeezed out, a form of mineral precipitation occurs and these minute mineral crystal structures attach themselves to, and cement together, the individual particles of sediment, whether they be sand grains, minute clay particles, pebbles, or boulders.
What is compaction and cementation?
Compaction does not necessarily cause materials to stick together. Cementation is more like having a binding material between the layers. Even compaction CAN result in binding together of materials such as sandstone.
Can deltas and caves result when running water such as a river erodes sediments from an area?
I'm afraid you've misunderstood sediment, and you can't concatenate two such different structures as you have. Sediment is deposited fragments of material sized from silt up to cobbles or boulders, resulting from weathering and erosion of any rock. Deltas are estuarine deposits of sediment transported suspended in the river, from erosion up-stream. Caves, or most of them anyway, do not result from erosion of sediments, but from the erosion by chemical weathering (dissolution) of sedimentary rock - specifically limestone - and the material is carried away in solution not suspension.
How does weathering and erosion change a mountain made of solid rock?
Weathering breaks or dissolves the rock and erosion transports the resultant sediments to another location. The result is a gradual reduction in the elevation of the mountain.
Why is burial usually necessary to turn a sediment into a sedimentary rock?
The key to converting sediment into sedimentary rock is often though of as being pressure. And it is only by burial that enough pressure can be generated on a layer of sediment to "press" it into sedimentary rock. With pressure and time comes what is called compaction and the expulsion of (most of) the space between the particles of sediment that were deposited. Let's look at sediments being laid down and turned into sedimentary rock.When sediments are created, moved and deposited, they can consolidate and form a layer or layers. These strata will be composed of particles of organic and inorganic material. Included will be the intersticial spaces between the sediments. Any water present in the pore spaces (and there usually is) will bring with it dissolved minerals. These can precipitate out in the spaces, and will cause cementation, which is the binding of these minerals to the particles of sediment and the "sticking together" of the sediments. Following the deposition of more material, pressure (lithostatic pressure) will build on the underlying strata. The compaction forces the layer to become more dense and to "turn to stone" over time. And sedimentary rock is the result of this process.
Describe the sequence of events in the formation of a sandstone?
The formation of sandstone involves two principal stages. First, a layer or layers of sand accumulates as the result of sedimentation, and then the sand becomes sandstone when it is compacted by pressure of overlying deposits.
What type of rock is the result of processing of sediments?
Sedimentary rocks.
