What is the weakest agent of erosion?
WindWind by itself is the weakest agent of erosion..
Is olivine resistant to weathering?
Olivine is a very common silicate mineral that occurs mostly in dark-colored igneous rocks like peridotite and basalt. It is usually easily identifiable because of its bright green color and glassy luster. … Olivine is actually very rare in sand because it is highly susceptible to weathering.
Which rock is least resistant to weathering?
graniteMarble is composed of a mineral that is resistant to chemical weathering (quartz), whereas granite is composed of minerals less resistant to weathering (like calcite). Marble is composed of minerals that resist weathering well, whereas granite has less of these minerals.
Is Clay a resistant rock?
The geology of an area is one of the key factors influencing the shape of the landscape: Stronger, more resistant rocks tend to produce highland areas, whereas weaker rocks tend to form lowlands; … Clay is an impermeable rock that tends to produce wet lowland areas.
What are the 5 types of chemical weathering?
Chemical processes need water, occurring more rapidly at higher temperature, so they are more common in warm and wet climates. There are different types of chemical weathering processes, such as solution, hydration, hydrolysis, carbonation, oxidation, reduction, and chelation.
What are some examples of sediment?
Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock. Tuffaceous sandstones contain volcanic ash.
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 is the slowest agent of weathering and erosion?
Wind- the least powerful can only move small pieces of rock. It is the slowest agent of erosion. Water- the most COMMON agent of erosion on Earth.
Is biotite resistant to weathering?
Although biotite is not very resistant to weathering and transforms into clay minerals, it is sometimes found in sediments and sandstones.
Which material is most resistant to chemical weathering?
QuartzQuartz is known to be the most resistant rock- forming mineral during surface weathering.
What is the most powerful form of erosion?
THE FORCES OF EROSION: WATER, GLACIERS, AND WIND But the most powerful erosive force on earth is not wind but water, which causes erosion in its solid form — ice-and as a liquid. Water in its liquid form causes erosion in many ways.
What is the fastest form of erosion?
moving water erosionThe fastest form of erosion is moving water erosion. If you look at the Grand Canyon in Arizona you can see the power of moving water.
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.
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.
Which of the following mineral is least resistant to chemical weathering most easily weathered )?
Chemical weathering reactions are with the cations that bind the silica structural units together. So it makes sense that isolated tetrahedra are the least stable in weathering, while quartz, which is completely formed of interlocking silica tetrahedra with no intervening cations, is the most stable.
Which rock type is the most resistant to erosion?
Metamorphic rocks are highly resistant to erosion and are often used in building materials.
Is Muscovite resistant to weathering?
Muscovite is relatively resistant to weathering and thus occurs in many soils developed over muscovite-bearing rocks and also in the clastic sediments and sedimentary rocks derived from them.
Which rock weathers most quickly?

Is chalk a resistant rock?
Natural chalk is highly resistant to erosion due to its porous structure. It is very often associated with clay, but is less resistant to clay erosion and weather conditions. This is more resistant and limestone when the clay is worn, mostly where the chalk ridges meet the sea, steep rocks and shelves.
What are 4 factors that affect weathering?

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.
