What else can I help you with?
Why would it be more likely to find a cave with limestone bedrock than granite?
Limestone bedrock is more likely to contain caves because it is easily eroded by acidic water, creating openings and cavities. Granite, on the other hand, is a harder and less soluble rock, making it less prone to forming caves through erosion.
Is the formation of stalactite and stalagmite in the cave of Jeita physical or chemical change?
Not really, it's more of evaporation. Rain water percolating through the earth laid over a limestone bedrock dissolves the limestone. The lime-water drips through cracks and forms caves. Evaporation of the drips leaves behind a tiny amount of limestone, that slowly forms the stalactites and stalagmites.
When limestone dissolves what happenns to the dissolved material?
When limestone dissolves, the dissolved material forms ions, primarily calcium and bicarbonate ions, in the water. These ions can then be carried away by the water through rivers or groundwater. Over time, this process can lead to the formation of caves and sinkholes.
What is the layer of solid rock found under the soil?
The layer of solid rock found under the soil is called bedrock. Bedrock is composed of consolidated rock that forms the base of the Earth's crust and provides a strong foundation for the layers above it.
The fundamental sedimentary unit is the?
bedrock, which forms the base of sedimentary layers and is composed of consolidated rock fragments or minerals deposited over millions of years.
Which is required for karst topography to form?
Karst topography forms in regions with soluble bedrock like limestone or dolomite that is prone to dissolution by groundwater. The presence of abundant rainwater, which is slightly acidic, plays a key role in dissolving the bedrock and creating the unique features of karst landscapes such as sinkholes, caves, and underground drainage systems.
Why would it be more likely to find a cave with limestone bedrock than granite?
Limestone bedrock is more likely to contain caves because it is easily eroded by acidic water, creating openings and cavities. Granite, on the other hand, is a harder and less soluble rock, making it less prone to forming caves through erosion.
What type of weathering creates karst topography?
Karst topography is created by chemical weathering, specifically by the dissolution of soluble rocks such as limestone and dolomite. This process forms features like sinkholes, caves, and underground drainage systems.
What dissolves limestone and forms caves or caverns?
Carbonic acid, which forms when rainwater combines with carbon dioxide in the atmosphere, dissolves limestone over time to form caves and caverns. This process, known as chemical weathering, gradually dissolves the calcium carbonate in limestone to create underground voids and unique geological formations.
Is the formation of stalactite and stalagmite in the cave of Jeita physical or chemical change?
Not really, it's more of evaporation. Rain water percolating through the earth laid over a limestone bedrock dissolves the limestone. The lime-water drips through cracks and forms caves. Evaporation of the drips leaves behind a tiny amount of limestone, that slowly forms the stalactites and stalagmites.
Why does karst topography only exist in some geographic locations?
most regions do not have limestone under the soil Most regions have rock layers other than limestone
Is bedrock a layer of mature residual soil?
Bedrock is not a layer of mature residual soil. Bedrock is the solid rock underneath the soil layers that make up the Earth's crust. Residual soil forms from the weathering of bedrock over time.
When limestone dissolves what happenns to the dissolved material?
When limestone dissolves, the dissolved material forms ions, primarily calcium and bicarbonate ions, in the water. These ions can then be carried away by the water through rivers or groundwater. Over time, this process can lead to the formation of caves and sinkholes.
What does groundwater naturally contain that allows it to dissolve limestone and caverns?
Carbonic Acid
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 forms when underground layers of limestone are dissolved by ground water?
Karst topography forms when underground layers of limestone are dissolved by groundwater. This process creates unique landforms such as sinkholes, caves, and underground drainage systems. The dissolution of limestone occurs due to its chemical composition and the acidic nature of groundwater.
How is chemistry related to Guatemala sinkhole?
Most sinkholes form when mildly acidic water dissolves limestone underground, this forms a limestone cave. A sinkhole occurs when the cave collapses.
