Is feldspar resistant to weathering
of a relatively weathering resistant mineral, feldspar.
When this mineral is completely hydrolyzed, clay minerals and quartz are produced and such elements as K, Ca, or Na are released..
Which material is most resistant to chemical weathering
QuartzQuartz is known to be the most resistant rock- forming mineral during surface weathering.
What conditions produce the fastest weathering
Weathering occurs fastest in hot, wet climates. It occurs very slowly in hot and dry climates. Without temperature changes, ice wedging cannot occur. In very cold, dry areas, there is little weathering.

What types of rock are vulnerable to weathering
Certain types of rock are very resistant to weathering. Igneous rocks, especially intrusive igneous rocks such as granite, weather slowly because it is hard for water to penetrate them. Other types of rock, such as limestone, are easily weathered because they dissolve in weak acids.
Which mineral would most likely become rounded at the fastest rate when stumble along
Right answer: Selenite gypsum.
What happens when a rock is crushed into a pile of fragments
What occurs when a rock is crushed into a pile of fragments? A The total surface area decreases and chemical composition changes.
Which action will best prevent groundwater erosion
using breakwaters packing down soil building drains with outlets increasing the slopes of riverbanks. Building drains with outlets would best help prevent groundwater erosion. Building drains with outlets would best help prevent groundwater erosion. This answer has been confirmed as correct and helpful.
Which rock will likely weather the least
Several types of rock, like granite, are very repellent to weathering. Moreover, Igneous rocks serve to heat slowly because it is difficult for water to penetrate into them.
What type of rock particles make up soil
The soil is composed primarily of minerals that are produced from parent material (rock) that is weathered, or broken into small pieces. Beyond occasional stones, gravel, and other rock debris, most of the mineral particles are called sand, silt, or clay. These mineral particles give soil texture.
Is sand a rock or mineral
Sand itself is not a mineral. It is a sediment just like clay, gravel and silt. Most common sand-forming mineral is quartz. There are two good reasons for that.

Which has the highest resistivity 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. Quartz is itself an agent of mechanical weathering in the form of blowing dessert sand.
How do minerals dissolve
During mineral growth and dissolution, material (in the form of atoms, molecules, complexes, or clusters) is transported through water to or from the mineral surface. Even in a solution that is at equilibrium with respect to a given mineral, there is transport to and from the surface.
What would happen if there were no rocks
The “NO ROCKS ON EARTH” condition would be very difficult to envision. That would mean that there would be no crust, separating the mantle from the asthenosphere. The heat exchange from that condition would cool the mantle and a new crust would form. … which the heat from the exposed mantle would prevent from forming.
What are 5 examples of weathering
These examples illustrate physical weathering:Swiftly moving water. Rapidly moving water can lift, for short periods of time, rocks from the stream bottom. … Ice wedging. Ice wedging causes many rocks to break. … Plant roots. Plant roots can grow in cracks.
What rock layer is most resistant to weathering
Igneous rocksIgneous 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. For example, limestone dissolves in weak acids like rainwater.
What mineral is most resistant to weathering
ZirconZircon proved to be the most resistant mineral considered, garnet the most readily destroyed in weathering. Other common heavy minerals show considerable range in resistance.
What mineral is least resistant to weathering
QuartzLeast resistant? Most stable: Quartz. Least stable: Olivine. What are the four main results or products of weathering?
Which factor has the greatest influence on the weathering rate of Earth’s surface bedrock
Regional climateRegional climate is the factor that has the greatest influence on the weathering rate of Earth’s surface bedrock.
Which mineral is most stable at the earth surface
mineral quartzThe only silicate mineral that is chemically stable at the earth’s surface (meaning it will not decompose into clay) is the mineral quartz.
