Which material is most resistant to chemical weathering?
Quartz is known to be the most resistant rock- forming mineral during surface weathering.
Which is more resistant to weathering?
Igneous rocks are usually solid and are more resistant to weathering. Intrusive igneous rocks weather slowly because it is hard for water to penetrate them. Sedimentary rocks usually weather more easily.
Which minerals are the most prone to chemical weathering?
Pyroxene, amphibole, magnetite, pyrite, and olivine are most susceptible to oxidation because they have high iron content. The ions released from silicate minerals in the weathering process are sodium, potassium, calcium, iron, and magnesium ions.
Which is least affected by chemical weathering?
Quartz, which is crystalline silica, is the only common mineral that is not strongly affected by chemical weathering. It does not dissolve in water. All other common minerals are either dissolved completely or are partially dissolved and reduced to clay.
Which material is most resistant to chemical weathering quizlet?
Silicate minerals that crystallize early (e.g., olivine) are least resistant to weathering, whereas silicate minerals that crystallize late (e.g., quartz) are most resistant. Additionally, a rock with cracks and/or holes is more susceptible to chemical weathering. Mechanical weathering would predominate.
Is clay resistant to weathering?
Not only is quartz the most stable of the common rock forming minerals in chemical weathering, its high hardness and lack of cleavage make it quite resistant to mechanical weathering.

Is limestone resistant to weathering?
Limestone in arid environments tends to be as resistant to weathering and erosion as sandstone, or more so. Limestone, however, has another property unlike sandstone or shale. Limestone is composed mostly of calcite (calcium carbonate) and will dissolve in acidic water.
Is granite resistant to weathering?
The effect of rock hardness on relief
Igneous rocks can be very hard. Granite, for example, is very resistant to weathering and erosion and so forms high, rugged landscapes such as Bodmin Moor in Cornwall or Dartmoor in Devon.
Which mineral is least resistant to weathering?
1. Table 6.2: Iron oxides, Al-hydroxides, clay minerals and quartz are the most stable weathered products whereas highly soluble minerals like halite are the least stable.

Which silicate mineral is the least resistant to chemical weathering processes?
Least resistant? Most stable: Quartz. Least stable: Olivine. What are the four main results or products of weathering?
Which of the following minerals is most resistant to chemical weathering quizlet?
Quartz is extremely resistant to all forms of chemical weathering. Quartz is not affected by hydrolysis, oxidation, or dissolution because it is an extremely resistant mineral. Sand dunes are typically dominated by quartz grains and very little other mineral matter.
Which mineral is most resistant to both chemical and physical weathering?
Not only is quartz the most stable of the common rock forming minerals in chemical weathering, its high hardness and lack of cleavage make it quite resistant to mechanical weathering. Quartz is itself an agent of mechanical weathering in the form of blowing dessert sand.
Is sandstone resistant to weathering?
Sandstone is a sedimentary rock that is highly resistant to weathering. Other sedimentary rocks you will encounter are mudstone and siltstone. These are soft and easily weathered (lots in the Painted Desert). Yet another sedimentary rock you will see is limestone.
Is quartz resistant to chemical weathering?
Not only is quartz the most stable of the common rock forming minerals in chemical weathering, its high hardness and lack of cleavage make it quite resistant to mechanical weathering.
What mineral is most resistant to weathering quizlet?
Which silicate mineral group is most resistant to weathering? Least resistant? Most stable: Quartz.
Which mineral is very resistant to physical as well as chemical weathering?
quartz
Not only is quartz the most stable of the common rock forming minerals in chemical weathering, its high hardness and lack of cleavage make it quite resistant to mechanical weathering.
What are the 4 types of chemical weathering?
There are five types of chemical weathering: carbonation, hydrolysis, oxidation, acidification, and lichens (living organisms).
What mineral is least resistant to weathering?
Which rock is most resistant to erosion?
Igneous rocks can be very hard. Granite, for example, is very resistant to weathering and erosion and so forms high, rugged landscapes such as Bodmin Moor in Cornwall or Dartmoor in Devon. Granite will eventually break down by chemical weathering.
Which of the following minerals is least resistant to chemical weathering?
Quartz is the second most abundant mineral in the earth’s crust. This is used in making jewelry and hard stone carvings. It is the hardest material and is least susceptible to chemical weathering.
Which rock is most resistant to both chemical and mechanical weathering?
Quartzite
Detailed Solution. Quartzite is most resistant to both chemical and mechanical weathering. It is a hard metamorphic rock.
Is Marble resistant to weathering?
Marble is composed of calcite, a mineral strongly resistant to weathering, whereas granite is composed of quartz, a mineral strongly reactive in water. Marble is composed of a mineral that is resistant to chemical weathering (quartz), whereas granite is composed of minerals less resistant to weathering (like calcite).
