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.
Why would basalt and gabbro generally have higher chemical weathering rates than rhyolite and granite?
Basalt and gabbro have higher chemical weathering rates than rhyolite and granite because they contain more ferromagnesian minerals like olivine and pyroxene that are more susceptible to chemical weathering compared to the quartz-rich minerals in rhyolite and granite. This makes basalt and gabbro more prone to breakdown and alteration when exposed to weathering agents like water and acids.
In wet climates granite weathers more slowly than?
In wet climates, granite weathers more slowly than limestone because granite is a harder and more resistant rock compared to limestone. The minerals in granite are less susceptible to dissolution by water and chemical weathering processes, leading to slower weathering rates.
Why does granite weather slowly?
Granite is a durable and dense rock made up of various minerals, including quartz, feldspar, and mica, that are resistant to weathering processes. This resistance to weathering is due to the hardness and chemical composition of these minerals, which make granite less susceptible to physical and chemical breakdown when exposed to the elements, resulting in slow weathering rates.
What mineral in granite rock hardly weathers?
Quartz is a mineral found in granite that is highly resistant to weathering, making it one of the most durable components of the rock. It retains its crystal structure and resists chemical breakdown over long periods of time.

Which statue is likely to be affected most in chemical weathering marble or granite statue?
A marble statue is likely to be affected more by chemical weathering compared to a granite statue. Marble is a softer and more porous rock than granite, making it more susceptible to chemical reactions with acids in the environment, such as acid rain. This can lead to the erosion and disintegration of the marble statue over time.

Which weathers faster granite or marble?
Marble will weather more quickly. The mineral calcite, of which marble is composed is softer and less resistant to abrasion than granite. It is also more susceptible to chemical weathering via natural and man-caused acidic rainfall due to its chemical composition. Granite--not so susceptible.
What is the product of chemical weathering of granite called?
The product of chemical weathering of granite is called clay minerals or clay sediments. These clay minerals result from the breakdown of feldspar, mica, and quartz minerals in granite due to chemical reactions with water and acids in the environment.
What minerals would be least immune to chemical weathering limestone quartz marble and granite?
The answer is marble because it is like glass and if there were a piece on the ground it could be easily broken but if there were a tornado the tornado couldnt break it. Marble is very fragile.
Granite and basalt are exposed at earth surface in a hot wet region. will mechanical weathering predominate which rock will weather most rapidly?
In hot, wet regions, chemical weathering tends to predominate over mechanical weathering. Basalt is more susceptible to chemical weathering due to its composition, specifically the presence of minerals like olivine and pyroxene, which are more reactive to water and acids. Granite, being a more resistant rock due to its composition of quartz and feldspar, will weather more slowly in this environment.
What are the effects of weathering on granite?
Weathering can cause physical and chemical changes to granite. Physical weathering can lead to the breakdown of granite into smaller pieces through processes like freeze-thaw cycles and abrasion. Chemical weathering can alter the mineral composition of granite through reactions with water and acids, leading to the formation of new minerals and weakening the structure of the rock.
Why does it take a long time for granite to break down?
Granite takes a long time to break down due to its composition and structure. It is primarily made up of hard minerals like quartz and feldspar, which are highly resistant to weathering and erosion. Additionally, granite's crystalline structure makes it less susceptible to chemical weathering compared to softer rocks. The process of breaking down granite into soil or sediment involves both physical and chemical processes that occur over extended periods, often spanning thousands to millions of years.
