What is the meaning of acidic magma?
Acidic magma is characterized by high silica content, resulting in a more viscous and explosive type of lava when erupted. This type of magma commonly leads to explosive volcanic eruptions, as the high silica content traps gases, leading to pressure buildup and explosive release. Examples of volcanic features associated with acidic magma include stratovolcanoes and pyroclastic flows.
Why is your rain water getting less acidic?
Rainwater can become less acidic due to natural processes like the dissolution of minerals and buffering by soil and rocks as the rainwater flows over them. Additionally, air pollutants like sulfur dioxide and nitrogen oxides, which contribute to acid rain, have decreased due to environmental regulations.
What are 5 characteristics of basic and acidic lava?
Basic lava has low viscosity, low silica content, high temperature, and flows easily over long distances. It typically produces gentle, effusive eruptions. Acidic lava, on the other hand, has high viscosity, high silica content, lower temperature, and tends to explode violently, leading to more explosive eruptions.
How does acid water leak out of the mine?
Acidic water can leak out of mines when it comes into contact with exposed rocks containing sulfide minerals. Through a natural process called oxidation, these minerals react with water and oxygen to produce sulfuric acid, which then flows out of the mine along with other dissolved metals. This acidic water can have negative impacts on the surrounding environment by contaminating water sources and harming aquatic life.
What do you call a substance that flows?
A substance that flows is called "liquid".
What happen when water flows through rock?
•Influences pH + redox • •Limestone makes it more basic. • •Sulfur- oxidation yields H2SO4
Why does water flows underground in limestone areas?
Water flows underground in limestone areas primarily due to the rock's solubility. Rainwater, slightly acidic from dissolved carbon dioxide, erodes the limestone, creating pores and channels over time. This process, known as karstification, allows water to flow through these underground passages, forming aquifers and contributing to the unique landscape features like caves and sinkholes. The porous nature of limestone facilitates the movement and storage of groundwater.
How is a cavern made?
Acidic ground water (rain-water that has absorbed atmospheric carbon dioxide to form carbonic acid) dissolving the limestone as it flows through the joints & other discontinuities in the rock mass.
How was caves made?
"... were made" !Acidic ground water (rain-water that has absorbed atmospheric carbon dioxide to form carbonic acid) dissolving the limestone as it flows through the joints & other discontinuities in the rock mass.
How were limestone caves at carlsbad cavern formed?
Limestone caves at Carlsbad Caverns were formed through a process known as chemical weathering, primarily involving the dissolution of limestone by slightly acidic water. Rainwater absorbs carbon dioxide from the atmosphere and soil, forming a weak carbonic acid that seeps into the ground. As this acidic water flows through cracks in the limestone, it gradually dissolves the rock, creating cavities and passages over millions of years. This process, combined with the subsequent erosion and the formation of stalactites and stalagmites, has shaped the stunning caverns we see today.
Why does limestone dissolve?
The reaction is (supposing that the acid is H2SO4): CaCO3 + H2SO4l = CaSO4 + H2O + CO2 The solubility of calcium carbonate in neutral water, at 25 0C, is very limited: 1,5 mg/100 mL.
How lime- stones caves formed?
Limestone caves are formed through a process called chemical weathering. Rainwater, which is slightly acidic, dissolves the limestone rock over time, creating small cracks. These cracks then widen as more water flows through, eventually forming caves. Additionally, some limestone caves are formed through the erosion of underground rivers.
Why water flows underground in limestone areas?
Water flows underground in limestone areas due to the rock's solubility, which allows it to dissolve and create cavities and channels over time. This process, known as karstification, forms underground rivers and aquifers. The porous nature of limestone facilitates the movement of water, enabling it to travel through these subterranean pathways. As a result, groundwater systems in limestone regions can be extensive and complex.

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.
