Which type of rock appear to be the least resistant to weathering and erosion?
Sedimentary rocks like sandstone and limestone tend to be less resistant to weathering and erosion compared to igneous or metamorphic rocks. Their softer composition and structure make them more susceptible to the effects of these processes.
What landscape feature is most likely to be formed from a bedrock layer that is resistant to erosion?
A ridge or a cliff would be most likely to form from a bedrock layer that is resistant to erosion. These features are created when surrounding softer rock is worn away, leaving the harder bedrock exposed.
What are less resistant rocks?
Less resistant rocks include sandstone, chalk, and limestone. These rocks are more susceptible to weathering and erosion compared to harder rocks like granite and basalt.
Which two rock types would you expect to see sitting next to each other after a very long period characterized by only uplift and erosion?
After a period of uplift and erosion, you would expect to see a hard, resistant rock type like granite sitting next to a softer, less resistant rock type such as shale. Granite is more resistant to weathering and erosion, while shale is easily weathered and eroded, which can lead to these two rock types ending up next to each other.
Is a sea stack formed by erosion or deposition?
A sea stack is formed by erosion. It is created when softer rock surrounding a more resistant rock is eroded away by the sea, leaving behind a standalone pillar of rock.
What mineral is very resistant to erosion?
Quartz.
What material makes the caprocks?
Caprocks are more erosion resistant rocks overlying less erosion resistant ones. The caprock could therefore be any resistant rock type as long as it aids in preventing the erosion of the layer below it. Sandstone and basalt lava flow are typical caprock layers.
Which is more resistant to weathering a rock or sand?
Rock is far more resistant to weathering (erosion) than sand.
Which type of rock appear to be the least resistant to weathering and erosion?
Sedimentary rocks like sandstone and limestone tend to be less resistant to weathering and erosion compared to igneous or metamorphic rocks. Their softer composition and structure make them more susceptible to the effects of these processes.
What are rocks that are resistant to erosion called?
Cap rock. Resistant cap rock will help protect softer rock below it from erosion. Any rock type that is more resistant to erosion than the rock type below it is called a cap rock. For instance, it could be basalt (igneous) overlying limestone (sedimentary), or limestone (sedimentary) over shale (also sedimentary).
What is the process by which softer less weather resistant rocks are worn away leaving more weather resistant rocks exposed?
Erosion.
Which is most resistant to water erosion quartzite shale or sandstone?
Quartzite
Are artificial levees resistant to river erosion?
yes this can happen due to runoff
How inselbergs are formed?
they are formed by volcanic processes that give rise to a rock resistant to erosion
What can you use iridium for?
Some iridium applications are: - alloy for fountain pen - components of catalysts - electrodes for sodium hydroxide production - spark plugs - crucibles highly resistant to corrosion - component in many expensive alloys resistant to corrosion, heat at and erosion - the isotope Ir-192 is a source of gamma radiation - the standard kilogram is an alloy of platinum with iridium
Why are metamorphic rocks good building materials?
They are normally hard and durable, and resistant to weathering and erosion.
What landscape feature is most likely to be formed from a bedrock layer that is resistant to erosion?
A ridge or a cliff would be most likely to form from a bedrock layer that is resistant to erosion. These features are created when surrounding softer rock is worn away, leaving the harder bedrock exposed.
