One characteristic that can help distinguish between sandstone and tuff is their composition. Sandstone is primarily composed of sand-sized mineral grains cemented together, while tuff is composed of volcanic ash and tephra fragments that have been compacted and cemented together. Tuff may also exhibit a finer texture due to the smaller size of volcanic particles compared to sand grains in sandstone.
What else can I help you with?
How can you tell that the sandstone was not deposited on top of the basalt?
The sandstone layer is older than the basalt. The older rock cannot be on top of the younger rock. The sandstone and the basalt (or basalt dike) are both deposited at the same depth.
How does basalt turn to sandstone?
Basalt is eroded to sand by wind and rain. The sand accumulates in ocean sediment and experiences great pressures over time. After a sufficiently long time, and uplift reveals what had been sand and has become sandstone.
Why might some rocks harder than others?
Not particularly. One notable characteristic of sandstone is that it is 'friable'. This means that is is crumbly. This mainly applies to Orthoquartzite (a 'posh' word for common sandstone), but as there are many other types, it is impossible to take all into account. Something like an Arkose or a Greywacke (yes, that is a real word!) is a little harder, but all sandstones consist of relatively weak cements, but very hard clasts (grains). Orthoquartzite, for example, consists entirely of Quartz, which is a very hard mineral, and indeed all sandstones contain a high proportion of quartz fragments. Overall, though, the stone itself is not hard, as a single grain removed from the rock is not the actual rock itself (when you walk on a beach, you are not walking on Orthoquartzite). This is only relative to other rocks. All rock, however, is relatively hard. Since all rock is brittle, this makes it good for building with, and so sandstone is used for building. At high pressure, however, it crumbles and cracks easily, so a sandstone structure cannot be too tall. From a geologist's perspective, it is weak, from a general perspective, it is useful for building (it is easy to acquire and use).
What is an important characteristic of an index fossil-?
a. pex: it might have lived in a very wide geographic region
The geographic isolation of a people frequently reinforces?
The geographic isolation of a people frequently reinforces the development of unique cultural practices, languages, and traditions that distinguish them from neighboring groups. This isolation can also contribute to the preservation of traditional ways of life and customs that might otherwise be lost due to external influences.
In what applications might businesses find it useful to distinguish between a human and a computer?
repairing mechanicals
How might a sandstone change into another sandstone?
Sand that is overlayed by additional sediments will experience compaction. Small gaps between sand particles will fill in with minerals which cement the particles together. The process takes a long, long time.
What are some properties of neon that help to distinguish it from other elements?
The most easily produced characteristic might be the colour of the light produced in an electric discharge tube. For others please see the link.
How can you tell that the sandstone was not deposited on top of the basalt?
The sandstone layer is older than the basalt. The older rock cannot be on top of the younger rock. The sandstone and the basalt (or basalt dike) are both deposited at the same depth.
What might the future hold for uluruwhy?
because it is a large sandstone rock
Distinguish between motivators and hygiene factor?
Hygiene factors can be a motivator but not necessarily the opposite. Someone might be motivated to be clean to date for example.
Did sand used to be a rock?
yep, and it might become rock again - sandstone.
What Is the opposite of characteristic?
Covet is a verb and cannot be a characteristic. A characteristic has to be some kind of noun. Covetousness might be a characteristic, and its opposite is generosity.
What is the opposite characteristic of covet?
Covet is a verb and cannot be a characteristic. A characteristic has to be some kind of noun. Covetousness might be a characteristic, and its opposite is generosity.
Is sandstone rock found in the Bahamas?
yes if you look around you might find some.
Why might sandstone act as a reservoir for ground water or oil well shale?
Sandstone is extremely porous and absorbs liquids like a sponge.. Shale is nearly impervious to liquids.
Does lortab show up as a opiate in urine drug screen?
It might, in a screen. More accurate tests can readily distinguish between hydrocodone and other opiates, though.
