When a granite intrudes into a layer of limestone which is younger granite or limestone?
When a granite intrusion occurs within a layer of younger limestone, the granite is considered older than the surrounding limestone. This is because intrusive rocks form before surrounding sedimentary rocks. If the intrusion occurs within older limestone, then the limestone is considered older than the granite.
What happens when it rains on limestone?
When rain falls on limestone, a chemical reaction occurs causing the limestone to dissolve. This process is called carbonation and results in the formation of calcium bicarbonate, which can be washed away over time by the rainwater. As a result, limestone can be weathered and eroded by rainfall.
What gas does acid rain on limestone produce?
When acid rain comes into contact with limestone, it produces carbon dioxide gas. This occurs due to a chemical reaction that dissolves the limestone, releasing carbon dioxide into the atmosphere.
Is marble and limestone an example of a metamorphic rock and its parent rock?
Yes, marble is a metamorphic rock formed from limestone, which is the parent rock. This process occurs due to the recrystallization of minerals within the limestone under high pressure and temperature conditions.
Do the formation of stalactites and stalagmites occurs in the zone of saturation?
Yes, the formation of stalactites and stalagmites occurs in the zone of saturation. Groundwater drips through the ceiling of a cave and leaves behind mineral deposits when the water evaporates, forming stalactites. When the water drips onto the cave floor, it leaves deposits that build up into stalagmites.
What process hollows out limestone in caves?
The process that hollows out limestone in caves is called chemical weathering. This occurs when rainwater combines with carbon dioxide in the atmosphere to create a weak carbonic acid, which gradually dissolves the limestone over time, resulting in the formation of caves and caverns.
What mineral is formed when co2 combines with another substance?
Calcite is a mineral that forms when carbon dioxide combines with calcium. This process typically occurs in caves, where water carrying dissolved CO2 drips onto limestone, resulting in the precipitation of calcite.
How is the release of carbon from limestone reservoirs into the atmosphere most often accomplished?
Carbon release from limestone reservoirs into the atmosphere most often occurs through human activities such as mining and quarrying operations. When limestone is extracted and processed, it can release carbon dioxide into the atmosphere, contributing to carbon emissions.
How is limestone formed in caves?
Limestone is formed in caves through a process called cave formation or speleogenesis. This occurs when water containing dissolved minerals, like calcium carbonate, seeps through cracks in the rock and evaporates, leaving behind deposits of limestone. Over time, these deposits can accumulate to form intricate cave structures.
What occurs when a molecule combines with oxygn and produces heat?
it combusts
When a granite intrudes into a layer of limestone which is younger granite or limestone?
When a granite intrusion occurs within a layer of younger limestone, the granite is considered older than the surrounding limestone. This is because intrusive rocks form before surrounding sedimentary rocks. If the intrusion occurs within older limestone, then the limestone is considered older than the granite.
Causes of corrosion?
occurs when iron combines with oxygen in the air
What type of weathering occurs when limestone is eaten away by chemicals in water?
Chemical weathering occurs when limestone is dissolved by chemicals in water. This process, known as carbonation, is caused by the reaction of carbon dioxide in rainwater with the calcium carbonate in limestone, forming calcium bicarbonate which is soluble in water.
What rock is formed when limestone is metamorphosed?
Marble is formed when limestone is metamorphosed. This process occurs when the mineral calcite in limestone recrystallizes due to heat and pressure, resulting in a denser, harder rock with a crystalline structure.
What reaction occurs when sulfuric acid and limestone mix?
it forms calcium sulphate
What product is produced when you mix limestone and aluminum?
When limestone and aluminum are mixed, a chemical reaction occurs to produce aluminum oxide and calcium oxide.
What happens when it rains on limestone?
When rain falls on limestone, a chemical reaction occurs causing the limestone to dissolve. This process is called carbonation and results in the formation of calcium bicarbonate, which can be washed away over time by the rainwater. As a result, limestone can be weathered and eroded by rainfall.
