What is the difference between angular unconformity disconformity and nonconformity?
Angular unconformity is when rocks are deformed and then eroded and then new sediment is deposited on top. Disconformity is when igneous or metamorphic rocks are eroded and then sediment is deposited on top. Nonconformity is when either there is no deposition for some time and then deposition resumes or horizontal layers are eroded (but not deformed in any way) and then deposition resumes. These create gaps in the rock record.
What causes igneous rock to become sediment?
The sedimentary rock melts,which causes magma. When the magma cools it becomes an igneous rock.
How does granite turn into sedimentary rock?
Granite becomes exposed, is weathered into small particles, erodes from transportation by water, ice, wind, and gravity, is deposited in still waters or in dunes, and is compressed and cemented into sedimentary rock. This is one example of a path it could take in the rock cycle. There are others.
How does speed affect where or how sediments are deposited?
The greater the speed the less sediment deposited. A delta is where a river slows way down and sediment is deposited at the mouth of the river.
What happens to the mountains and deep valleys that makes the earth's surface uneven?
The valleys cut their way down to sea level and as this happens the mountains get eroded away to (by rain, ice and wind). The end stage is that the flatish land surface becomes almost level with the high tide of the sea. However the sediments eroded away get deposited on the ocean deeps and when the continents crash together again these form new mountains.

What are the steps or processes that lead to sedimentary rock formation?
Sedimentary rock can form in more than one way. The majority of sedimentary rock is clastic sedimentary rock, formed from the weathering and erosion of existing rock. The steps in its formation are listed below. Steps 4 and 5 are often listed together as the process of lithification.Weathering of pre-existing rock into smaller pieces.Erosion and transportation of weathered rock particles (sediments).Deposition of eroded sediments.Compaction of deposited sediments.Cementation of compacting sediments.For further explanation of sedimentary rock formation, see the related question below.
Can a metamorphic rock break in half then one half turns into a igneous rock and the other into a sedimentary rock?
The only way a metamorphic rock can become a sedimentary rock is if it is eroded and the pieces settle in a body of water and eventually become sedimentary rock. A whole piece of metamorphic rock is never going to become , by itself, a piece of sedimentary rock.
What type of rock will the erosion on a mountain make?
It will probably make some sort of sedimentary rock, because if the eroded sediments were put under enough pressure they might eventually meld together. Be careful though because there are different kinds of sedimentary rock. You wouldn't be able to tell which type of rock it formed unless you knew the type of rock eroded and the conditions they eroded in (is it a tropical area, arctic are, polar area, etc), it would also depend on how deep the rocks got buried and ho quickly. I hope that helps you out. By the way I'm in 8th grade taking Earth Science in case you are wondering where I got my info from!
Where was the material eroded from the grand canyon deposited?
The material eroded from the Grand Canyon was deposited on a plain. Over many years, water eroded the plain creating a canyon later known as the Grand Canyon. The water kept weathering down the rocks until it came down to a lower level way below the top of the Grand Canyon. That is why today we have a higher and lower part of the Grand Canyon. Overall, the Grand Canyon started out as a plain and as many years passed water weathered down the rocks.
What causes igneous rock to become sediment?
The sedimentary rock melts,which causes magma. When the magma cools it becomes an igneous rock.
How are a moraine and an erratic different?
A moraine is a pile of rocks and dirt deposited in a heap, usually at the end of a glacier. An erratic is a large stone or boulder that has been deposited in a similar way when glaciers retreated, being of a totally different type of rock to that on which it was deposited.
What is a sentence that uses the word weathering correctly?
'' Over the years , weathering changed the way a rock or mountain formed'' .
When a cave as eroded all the way through?
when a cave has eroded all the way though it is called an arch. hope you agree to my advise. :)
What kind of rock is formed from sediments deposited in bodies of water?
Sedimentary rock is formed from sediments deposited in bodies of water. Examples of sedimentary rocks that can form in this way include limestone, shale, and sandstone. These rocks are typically composed of particles that have been weathered, transported, and compacted over time.
How does granite turn into sedimentary rock?
Granite becomes exposed, is weathered into small particles, erodes from transportation by water, ice, wind, and gravity, is deposited in still waters or in dunes, and is compressed and cemented into sedimentary rock. This is one example of a path it could take in the rock cycle. There are others.
What role do rocks have within the rock cycle?
After many years, as rocks are eroded, gases trapped in them will be released into the atmosphere so in a way rocks are "storage rooms" for gases just as our Earth is.
