Why does limestone bubbles when acid is added to its surface?
Limestone contains calcium carbonate, which reacts with acid (such as hydrochloric acid) to form carbon dioxide gas. The release of carbon dioxide gas creates bubbles or fizzing on the limestone surface.
How did the rate of loss of the limestone change from the beginning of the experiment to the end?
The rate of loss of limestone increased as the experiment progressed. Initially, the reaction between the acid and limestone was slower, resulting in a lower rate of loss. However, as more limestone was consumed and the surface area for the reaction increased, the rate of loss of limestone accelerated.
Does acid rain attack limestone?
Yes, acid rain can chemically attack limestone by dissolving the calcium carbonate in the stone. This process, known as chemical weathering, can deteriorate the surface of limestone structures over time.
Does sodium sulphate damage limestone?
Yes, sodium sulfate can react with limestone and cause damage over time due to sulfation reaction. This reaction can lead to the formation of gypsum, which can then cause cracking and deterioration of the limestone surface.
Would rust damage limestone?
Yes, rust can potentially damage limestone if it comes into contact with it. The iron oxide in rust can cause staining, discoloration, and deterioration of the limestone surface over time. It's important to prevent rust from contacting limestone to maintain its appearance and integrity.
What Regions of the earths surface where limestone is exposed and abundant are called?
Regions of the Earth's surface with abundant limestone exposed are typically known as limestone terrains or limestone landscapes. These regions often feature distinctive topography due to the erosion of the soluble limestone rock by water, forming features such as caves, sinkholes, and limestone pavements.
When limestone on the surface is dissolved by ground water it forms?
When limestone on the surface is dissolved by groundwater, it forms features such as caves, sinkholes, and disappearing streams, through a process known as karst topography. This occurs because limestone is a rock that can easily be dissolved by the slightly acidic nature of groundwater, creating these unique geological formations over time.
Where can limestone caves befound?
generally, in limestone uplands, where the limestone is sufficiently massive to hold caves, and particularly but not exclusively where the local surface drainage can concentrate rainwater into discreet streams than can then form sink caves when they flow onto the limestone.
What Is missing in most areas that do not have karat topography?
Most areas without karst topography lack unique surface features such as sinkholes, caves, and disappearing streams. Karst topography is characterized by the dissolution of soluble rocks like limestone, creating distinctive landforms that are absent in other regions.
Type of rock common in karst area?
Limestone is a common type of rock found in karst areas. Karst landscapes are characterized by the presence of limestone rock that is susceptible to dissolution by natural processes, creating unique surface and subsurface features such as sinkholes, caves, and disappearing streams.
If limestone was crushed what would it do to the rate of reaction between an acid and the limestone?
Crushing limestone would increase the surface area available for the acid to react with, thus increasing the rate of reaction between the acid and the limestone. This is because more particles of limestone would be exposed, allowing for more frequent collisions with the acid molecules.
Why was sandstone used to build the cumbria bridge and not limestone?
limestone is not used in Columbia because crevices are present on its surface, while sand stone has porous surface which readily absorbs pollutants.
How is the Gibson Desert in Australia unique?
It is unique because of its treeless surface and its limestone geology
What percentage of Earth's surface is covered by limestone?
I think it is 75 % of the earths surface is covered by limestone
Why does th surface of limestone crumble when heated?
The surface of limestone crumbles when heated because heat causes the moisture and other volatiles in the limestone to evaporate rapidly, leading to a process known as thermal spalling. This rapid evaporation creates pressure within the limestone, leading to the breakdown of its structure and causing it to crumble.
What region in Mexico has limestone?
Several regions throughout Mexico have considerable deposits of limestone, but the Yucatan Peninsula is the largest of them all, being mostly a flat land composed of limestone. Due to this nature, there are almost no surface rivers in the peninsula and most water comes from holes in the ground known as cenotes.
How are resurgent streams formed?
Resurgent Stream arise when the limestone is underlain by an impermeable rock, such as clay. this forces the water out into the open, forming a spring or resurgent stream.
