What is a granite weathering?
Granite weathering refers to the process by which granite, a type of igneous rock, breaks down and wears away over time due to exposure to elements such as water, wind, and temperature changes. This weathering can cause physical and chemical changes to the rock, leading to its eventual dissolution or erosion.
How does granite weather?
Granite weathers through physical and chemical processes. Physical weathering can occur through temperature changes causing expansion and contraction, while chemical weathering involves reactions with water and acids that can break down the minerals in the granite. Over time, these processes can lead to erosion and the formation of characteristic features such as joints and fractures.
How human activities modify granite landforms?
Human activities can modify granite landforms through activities such as quarrying, mining, construction of roads and structures, and agriculture. These activities can involve excavation, blasting, and grading of granite outcrops, leading to changes in the natural topography and landforms of granite areas. Additionally, human development can also alter the water flow patterns and drainage systems in granite landscapes, impacting erosion rates and sediment transport.
2 Describe what happens to each mineral within granite during the complete chemical weathering of granite in a humid environment?
During chemical weathering in a humid environment, feldspar in granite transforms into clay minerals due to hydrolysis, resulting in the breakdown of granite into smaller particles. Quartz, being resistant to weathering, remains relatively unchanged. Minor minerals like micas can also weather, with biotite breaking down into clay minerals while muscovite may weather into vermiculite or kaolinite.
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.
When granite rocks get metamorphosed they changes into?
marble
What is used to bond granite to granite?
Epoxy resin is commonly used to bond granite to granite. It provides a strong and durable bond that is resistant to moisture and temperature changes, making it a popular choice for joining granite surfaces.
What type of rock forms as heat and or pressure causes changes?
Granite

What does granite changes into?
If broken down it turns into sandstone. If morphed it turns into gneiss.
Is it safe to put a hot pan on granite?
It is generally safe to put a hot pan on granite, as granite is heat resistant and can withstand high temperatures. However, sudden extreme temperature changes can potentially cause the granite to crack or break, so it is recommended to use a trivet or hot pad to protect the granite surface.
Is it safe to put hot pans on granite countertops?
It is generally safe to put hot pans on granite countertops, as granite is heat resistant. However, sudden extreme temperature changes can potentially cause the granite to crack or discolor over time. It is recommended to use trivets or hot pads to protect the granite surface from direct heat exposure.
Is the corrosive action of acid rain on granite a physical property?
The corrosive action of acid rain on granite is a chemical property. It involves a chemical reaction between the acid in the rain and the minerals in the granite, leading to its deterioration over time. This reaction changes the chemical composition of the granite, making it a chemical property.
What is the difference between red granite and granite?
The composition changes the appearance and colour of the granite. A granite that appears more red in colour will have more of the mineral orthoclase feldspar, whereas the lighter and more white in appearance will have less orthoclase and maybe more plagioclase feldspar and quartz in the composition.

When granite is subjected to high enough amounts of heat and pressure to change but not melt it granite changes into?
When granite is subjected to high heat and pressure without melting, it transforms into a type of metamorphic rock known as gneiss. This process involves the recrystallization of minerals within the granite, leading to a banded or foliation structure typical of gneiss. The minerals within the granite, such as quartz and feldspar, may realign and change in composition due to the extreme conditions.
When granite is subjected to high amounts of heat and pressure to change it but not melt it granite changes into?
When granite is subjected to high amounts of heat and pressure without melting, it transforms into a metamorphic rock known as gneiss. This process, called metamorphism, alters the mineral composition and texture of the granite, resulting in the formation of foliation and banding visible in gneiss. The minerals within the granite recrystallize under the extreme conditions, leading to a denser and more durable rock.
