What would weather faster exposed limestone in southern Florida or exposed granite in northern Canada?
Limestone in southern Florida, because carbonic acid would make it weather faster. Another gas found in air, carbon dioxide, also causes chemical weathering. Carbon dioxide dissolves in rainwater and in water that sinks through air pockets in the soil. The result is a weak acid called carbonic acid. Carbonic acid easily weathers rocks such as marble and limestone.

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.
Which rock weathers most rapidly when exposed to acid rain?
Limestone weathers most rapidly when exposed to acid rain due to its high calcium carbonate content which reacts with acidic water to form soluble calcium bicarbonate, leading to its dissolution.
What happens when limestone is exposed to air for two days?
When limestone is exposed to air for two days, it can undergo a chemical reaction with carbon dioxide in the air to form calcium carbonate, which may result in weathering or erosion of the limestone surface. This process is known as carbonation and can lead to the formation of cracks or pits on the limestone surface over time.
How is limestone pavement formed?
Limestone pavement is formed through a combination of weathering and erosion processes acting on the surface of limestone rock. This typically involves the dissolution of calcium carbonate in the limestone by rainwater, which creates fissures and cracks on the surface. Over time, these fissures widen and deepen, resulting in the characteristic large, flat slabs of rock separated by deep grooves that are typical of limestone pavement landscapes.
What is sedimentary rock that forms calcium carbonate and fizzes in acid?
The sedimentary rock that forms calcium carbonate and fizzes in acid is likely limestone. Limestone is a common sedimentary rock primarily composed of calcite, a form of calcium carbonate. When exposed to acids such as vinegar or hydrochloric acid, limestone will fizz or effervesce due to the release of carbon dioxide gas.
What would weather faster exposed limestone in southern Florida or exposed granite in northern Canada Explain?
Exposed limestone in southern Florida would weather faster than exposed granite in northern Canada due to several factors. Limestone is more susceptible to chemical weathering, particularly from acidic rain and humidity, which are prevalent in Florida's subtropical climate. In contrast, granite is a harder igneous rock that weathers more slowly, and the colder climate of northern Canada can limit the effects of physical weathering processes. Thus, the combination of limestone's composition and Florida's warm, humid conditions accelerates its weathering compared to granite in a cooler environment.
What time of the year is the southern hemisphere exposed to vertical rays of the sun?
When the northern hemisphere is in winter, the southern hemisphere is in summer.
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 is exposed to intense heat and pressure it becomes what metamorphic rock?
When limestone is exposed to intense heat and pressure, it metamorphoses into a rock called marble. Marble is a metamorphic rock that forms when the calcite crystals in limestone recrystallize and interlock.
Is the burren limestone?
Yes! The Burren is a karst-landscape located in western Ireland made up of exposed limestone bedrock.
Which rock weathers most rapidly when exposed to acid rain?
Limestone weathers most rapidly when exposed to acid rain due to its high calcium carbonate content which reacts with acidic water to form soluble calcium bicarbonate, leading to its dissolution.
Can a limestone fire pit explode when exposed to high temperatures?
Yes, a limestone fire pit can potentially explode when exposed to high temperatures due to the risk of thermal shock caused by rapid heating and cooling.
What happens when limestone is exposed to air for two days?
When limestone is exposed to air for two days, it can undergo a chemical reaction with carbon dioxide in the air to form calcium carbonate, which may result in weathering or erosion of the limestone surface. This process is known as carbonation and can lead to the formation of cracks or pits on the limestone surface over time.
Why is the southern hemisphere of mars believed to be older than the northern?
The southern hemisphere of Mars is believed to be older than the northern hemisphere because of extensive cratering patterns. The abundance of craters in the southern hemisphere suggests that it has been exposed to impacts for a longer period of time, indicating an older surface compared to the northern hemisphere. This could be due to differences in geological processes and history between the two hemispheres.
How was the burren created?
The Burren was made from years of weathering to create an area of exposed limestone bedrock.
What physical and chemical weathering changes could limestone be exposed to in the future?
erosion, acid rain...
What happens if people are exposed to limestone?
Limestone, or calcium carbonate, is entirely harmless in solid form, and exposure will not affect people in any way. However, if you inhale limestone dust, it will irritate the lungs, as does any kind of dust.
