Because different parts of the sedimentary rock have characteristics that are slightly more or less susceptible to dissolving in weak acids.
The dissolution takes place along the walls of tension-joints, bedding-planes and other discontinuities within the rock, that can pass the water through th formation to a suitable outlet (spring). If you look at limestone "pavement" you will see it is etched into a criss-cross pattern of "grykes" - deep trenches - along the joints.
What else can I help you with?
How are Clints and grikes form?
By chemical weathering leaving gaps in the limestone (grykes) and slabs of rock outside them (Clints)
Why does chemical weathering form gaps in limestone?
By dissolving the walls of the existing tension-joints in the limestone. The characteristic grid formation of sculpted limestone blocks separated by deep, narrow gullies is called Limestone Pavement; the blocks are the Clints, the gaps that mark out the joints are the Grykes. (My own mnemonic is "Grykes grin"!)
How is Clint rock formed?
Clints are formed by chemical weathering. This leaves gaps in the limestone, and slabs of rock outside them, which are called clints.
What substance can enter into gaps between the grains in limestone?
i dunno to eb honest. btw sorry for upsetting you as i dont know the question myself.but i just tryed this
What are Clints in limestone?
Clints are the raised blocks or sections of limestone pavement that are surrounded by grykes, which are the deep fissures or cracks in the pavement. They are formed by the natural processes of weathering and erosion over time, creating a characteristic pattern of blocks and gaps in limestone landscapes.
How long do grikes take to form?
Grikes, the gaps between limestone blocks in karst landscapes, can form over a long period of time, often taking thousands to millions of years to develop through the process of chemical weathering and erosion. The exact timeframe can vary based on factors such as the type of rock, climate, and geological conditions in the area.
Why does limestone begin to look like pavements with lots of gaps?
Limestone can appear like pavements with gaps due to a process called "karst topography," which occurs when slightly acidic rainwater erodes the rock over time. This dissolution creates fissures, cracks, and sinkholes, resulting in a rugged landscape resembling a pavement with gaps. The gaps, or sinkholes, can vary in size and depth, contributing to the unique appearance of limestone formations. Additionally, biological factors, such as plant roots, can further facilitate the breakdown of limestone, enhancing this pavement-like appearance.
What are the effects of expansion and contraction?
Expansion and contraction can cause things to crack, as in the weathering of rock. They can cause a bi-metal strip to bend and straighten, which phenomenon is used in some thermostats. Expansion can cause the roadway of a bridge to buckle, so gaps have to be left. Obviously they cause the thread in a liquid-in-glass thermometer to get longer and shorter.
What is bad about limestone?
Some problems are: 1. Dust pollution: the surrounding greenery is covered in a layer of dust 2. Noise pollution: loud explosions every day 3. Lorries carrying limestone to and fro cause noise and pollution 4. Quarries damage the landscape 5. Quarries destroy natural animal habitats etc etc.
cause of backlash when starting an 02 fatboy?
gaps
What do you see when limestone is heated very strongly?
simply it breaks out due to forming of carbon dioxide in the gaps if it takes place in an close atmosphere with high pressure than turns into marble.
What are large gaps in the asteroid belt often called Kirkwood gaps are caused by?
Kirkwood gaps are caused by the gravitational influence of Jupiter on the asteroids in the asteroid belt. Jupiter's gravity creates resonant orbits that cause asteroids to avoid specific regions in the belt, creating these gaps.
