What type of rock is not easily eroded by water?
Igneous rocks, particularly those that are dense and hard, such as granite, are not easily eroded by water. Their crystalline structure makes them resistant to weathering and erosion compared to softer sedimentary or metamorphic rocks. Additionally, basalt, another type of igneous rock, is also quite durable against water erosion. Overall, the hardness and density of these rocks contribute to their resistance to erosion.
Why sedimentary rocks found as veneer?
Sedimentary rocks are often found as veneer because they are easily weathered and eroded, allowing them to be transported and deposited in various locations. Over time, these sediments can accumulate and form layers, creating a veneer of sedimentary rocks on the Earth's surface.
Why do igneous rocks stick up above the ground?
Igneous rocks can stick up above the ground due to processes like uplift and erosion. Uplift can lift rocks from beneath the surface to create mountains or hills, while erosion gradually wears away softer rocks to expose harder, more resistant igneous rocks at the surface.
Igneous rock is eroded and what to the bottom of a river eventually forming what kind of rock?
Igneous rock eroded in a river will eventually form sediment, which can be compacted and cemented to become sedimentary rock. Examples of sedimentary rocks include sandstone, shale, and limestone.
Does igneous rocks absorb water?
igneous rocks do absorb water because of all the pores ,cracks, and holes in them. The holes will absorb the water and the water will get trapped in the rock there for igneous rocks do absorb water.
Are sedimentary rocks easily eroded?
YES! Sedimentary rocks, like sandstone, limestone and chalk can easily be eroded. This is because the grains in them (different to particles) are further apart to the grains in rocks like igneous rocks. This means that the grains can easily be crumbled off, and you get left with sand.
Can an igneous rock be changed?
Yes, igneous rocks can be metamorphosed or weathered and eroded.
Which type of rock appears to be the most easily eroded by the river in this area?
Sedimentary rocks tend to be the most easily eroded by rivers due to their composition and structure, especially rocks like sandstone and shale. These rocks are often softer and more porous compared to igneous or metamorphic rocks, making them more susceptible to weathering and erosion processes.
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.
Which type of rocks can be weathered and eroded?
All types of rocks can be weathered and eroded. However, sedimentary rocks are typically more susceptible to weathering and erosion compared to igneous and metamorphic rocks due to their composition and structure.
How do noncomformities form?
A nonconformity is a place where sedimentary rocks are found on top of eroded igneous or metamorphic rocks. The igneous or metamorphic rocks can be pushed up by forces inside the Earth. Then, erosion can remove some of the rock. Later, sediment may be deposited on top of the eroded rock.
What occurs when sedimentary rocks are deposited on top of uplifted and eroded metamorphic or igneous rocks?
An uncomformity will occur in the rock record.
What classification or kind of rocks results when rocks eroded from higher elevations accumulate at lower elevations?
asial sedimentary igneous metamorphic
Where igneous rocks are found?
Igneous rock can be found on the surface in areas of current or recent volcanism or in uplifted and eroded areas of past platonic intrusions, deep underground nearly anywhere, or in areas of past or present glaciations, where igneous rock has been eroded and deposited.
What rocks are easily eroded by acid rain?
Calcium based rocks like chalk, limestone and marble are some examples of rocks easily erroded by acid rain.
Where are igneous rocks?
Igneous rock can be found on the surface in areas of current or recent volcanism or in uplifted and eroded areas of past platonic intrusions, deep underground nearly anywhere, or in areas of past or present glaciations, where igneous rock has been eroded and deposited.
Does an igneous rock always becomes a sedimentary rock?
No. There some very old igneous rocks to be found also it is possible for an igneous rock to become a metamorphic rock. Further, igneous rocks can not be turned into a sedimentary rocks directly. They must first be weathered and eroded and only then their detritus and remnants can be deposited as a new sedimentary deposit.
