Limestone was formed over millions of years on the sea floor from the skeletal remains of minute sea creatures. Subjected to immense pressure, the layers hardened to form limestone. Upheavals that lifted up the sea floor, raised the limestone to form the limestone rock we find on the land.
Limestone (calcium carbonate) is a general term for such sedimentary rocks, of which chalk is another kind.
What else can I help you with?
What rock is commonly weathered in cave formation?
Limestone.
What is the main cause for cave formation?
Dissolving limestone.
What type of climate would soil form fastest from limestone bedrock?
A warm and humid climate would lead to rapid soil formation from limestone bedrock. The combination of warmth, moisture, and chemical weathering would accelerate the breakdown of the limestone and the formation of soil.
What would you find under Kaibab limestone if you were to drill a hole into the Kaibab limestone?
If you were to drill a hole into Kaibab limestone, you would likely find either Toroweap Formation or ancient sandstone layers beneath it. The Toroweap Formation usually underlies the Kaibab limestone in the Grand Canyon region.
The metamorphism of limestone results in the formation of?
The metamorphism of limestone results in the formation of marble. Marble typically forms when limestone undergoes intense heat and pressure deep within the Earth, causing its minerals to recrystallize into a harder, denser rock with a distinct appearance.
Is limestone cave formation chemical or mechanical weathering?
chemical change
What reactions with water lead to the formation of caves with limestone?
The reaction of carbon dioxide in rainwater creates a weak carbonic acid, which dissolves limestone over time. This process, known as carbonation, leads to the formation of caves in limestone formations. Over thousands of years, the acidic water dissolves the limestone, creating underground tunnels and chambers.
What rocks are waterfalls made of?
The first hard layer is the Lockport Formation, which is made from limestone. The secound is softer, and is the Rochester Formation, and is made from shale and some very thin limestone bits. The third layer is underwater, and is Queenston Formation, which is made from shales and fine sandstone.
The formation of Karst topography requires carbonic acid to react with?
limestone
How are limestone caves different to other caves?
Primarily in their mode of formation: dissolution of limestone by water acidified by atmospheric CO2 (forming carbonic acid).
What do you think happened between the formation of superior limestone and the Columbia limestone?
The formation of the Superior limestone and the Columbia limestone likely involved significant geological processes such as changes in sea levels, sedimentation patterns, and tectonic activities. Over time, the environment shifted from the conditions that produced the Superior limestone, characterized by shallow marine environments, to the Columbia limestone, which may have developed under different sedimentary conditions or during a different geological period. These transitions often reflect broader climatic changes and evolving ecosystems that influenced the deposition of limestone in various geologic settings.
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.
