Do limestone from areas where shelled sea creatures are highly abundant contain more carbonate or not?
Yes, limestone from areas where shelled sea creatures are highly abundant typically contains more carbonate. Shelled sea creatures like mollusks and corals have shells made primarily of calcium carbonate. Over time, as their shells accumulate and get compacted, they form limestone. As a result, limestone from these areas will have a higher carbonate content compared to limestone from areas without such abundant sea creatures.
Which is missing in most areas that do that do not have karst topography?
Limestone
How is conical hill formed?
Conical hills are the remains/remnants of a limestone surface and all are usually the same height above sea level
How does limestone react when exposed to weak acids?
If the water contains any carbonic acid (if its rain water) then it will slowly dissolve/disintegrate the limestone.
What areas had a high concentration of limestone from 1890-1920?
northern Michigan
Can caves be formed in areas of slate?
No. Most caves are formed out of limestone making that false.
How would a cave be formed on earth?
Caves are generally formed in areas rich in limestone, which erodes as water flows over it over time.
Where are solutional caves located?
Solutional caves are formed in areas with soluble rocks such as limestone, gypsum, and dolomite. These types of caves are found worldwide, but are particularly common in regions with limestone bedrock, such as parts of the United States (such as Kentucky and Florida), Mexico, the Caribbean, and parts of Europe and Asia.

Why is a resurgent stream only formed in a limestone area?
A resurgent stream is formed when an underground river is forced to reappear when it reaches a layer of impermeable bedrock. For a river to become an underground river in the first place it must flow over an area of limestone rock. The mildly acidified river water (it is acidified by dissolved carbon dioxide which is present in rainwater) reacts with the limestone (which is 80% calcium carbonate) and dissolves it. This forms a swallow hole into which the river flows. The river then continues to chemically weather the limestone underground thus forming an underground river. The river is forced to reappear (in the form of a resurgent stream) on the surface when there is a change of rock type from permeable limestone to impermeable bedrock. Hence resurgent streams are typically only found in limestone areas.
What type of lithology is expected in the shoal areas - sandstone or limestone?
Sandstone. Limestone is of deeper water formation.
Why are limestone caves so common?
Limestone caves are common because limestone is a soluble rock that dissolves easily in water. Over time, groundwater flowing through cracks in the limestone gradually enlarges these passages to form caves. Additionally, limestone is often found in areas with karst topography, characterized by sinkholes, underground rivers, and other features that promote the formation of caves.
What are the areas of the Caribbean Community?
economic integration through the caribbean common market
How is conical hill formed?
Conical hills are the remains/remnants of a limestone surface and all are usually the same height above sea level
What type of rock is usually present in areas with a lot of caves?
Limestone is the type of rock that is commonly found in areas with a lot of caves. Limestone is made of calcium carbonate, which is soluble in water. Over time, as rainwater seeps into the ground, it dissolves the limestone and creates openings and caves in the rock.
In some areas limestone is found underneath the soil. In these areas water can wear away limestone and sinkholes may form on the surface. What is responsible for the formation of sinkholes?
physical weathering
