Why is soil thicker over limestone than over quartzite?
Soil is typically thicker over limestone than over quartzite because limestone is more soluble and reactive with water, leading to greater weathering and the formation of a deeper soil profile. The calcium carbonate in limestone breaks down more easily, releasing nutrients that contribute to soil development. In contrast, quartzite is highly resistant to weathering due to its silica content, resulting in thinner, less developed soils. This difference in mineral composition and weathering rates accounts for the variation in soil thickness.
What statement best explains why the soil is thicker above the limestone than it is above the quartzite?
The limestone is more easily weathered than quartzite, leading to the formation of thicker soil above it. Limestone is more prone to chemical weathering, which breaks it down and creates a thicker layer of soil over time compared to the more resistant quartzite.
How do grikes form?
Grikes form through the chemical and physical weathering of limestone bedrock by the dissolving action of water. Over time, this weathering process creates deep grooves or crevices in the limestone, resulting in the characteristic appearance of grikes in limestone pavement landscapes.
Is limestone dissolved by carbonic acid a chemical weathering or a mechanical weathering?
This is chemical weathering. Carbonic acid (and often sulphuric acid from SO2) destroy CaCO3 (limestone) through chemical attack.Carbonic acid is formed by reaction of H2O and CO2 to create H2CO3.
What examples of rocks are easily weathered and rocks that are resistant to weathering?
limestone,sandstone,and shale
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.
Why is quartzite more resistant to weathering than limestone?
Quartzite contains mostly quartz, which is a very hard and durable mineral that is resistant to weathering. Limestone, on the other hand, is made mostly of calcite, which is more easily dissolved and eroded by acidic water. This difference in mineral composition accounts for quartzite's greater resistance to weathering compared to limestone.
Why is limestone least resistant to weathering and erosion?
It is susceptible to chemical weathering more than other rocks from exposure to naturally acidic rainfall and groundwater.
What are examples of rocks that are easily weathered and rocks re resistant to weathering?
Examples of rocks that are easily weathered include limestone, sandstone, and shale, which are sedimentary rocks. Rocks that are resistant to weathering include granite, basalt, and quartzite, which are igneous and metamorphic rocks that have a more crystalline structure and are less prone to chemical breakdown from weathering processes.
Does granite or limestone last longer in normal rain?
Granite lasts longer as it is far more resistant to chemical weathering.
Which formations appear to be the most resistant to weathering?
Igneous rocks are typically the most resistant to weathering due to their dense and crystalline structure. Metamorphic rocks can also be highly resistant depending on the degree of recrystallization they have undergone. Sedimentary rocks like sandstone and limestone are generally more susceptible to weathering compared to the other two types.
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.
Two identical statues are placed outsideone is made of limestone the other made of granite Which statue will weather more slowly?
I'll say granite because the limestone as you know, is faster to it's weathering.
Which one is slow at weathering limestone or granite?
Limestone weathers faster than granite because it is more susceptible to chemical weathering due to its composition of calcium carbonate. Granite, on the other hand, is a more resistant rock as it is composed of harder minerals like quartz and feldspar.
Which is harder gabbro or limestone?
Gabbro is harder than limestone. Gabbro is a dense, coarse-grained rock formed from cooled magma, while limestone is a sedimentary rock primarily composed of calcite. Gabbro is more resistant to scratching and weathering compared to limestone.
How reactive is limestone?
Limestone is a relatively non-reactive rock. It is generally resistant to chemical weathering, but can slowly dissolve in acidic solutions over time. This makes it susceptible to erosion when exposed to acidic environments.
