Thus, the erosion of marble or limestone surfaces and the loss of detail on statuary are an important area of concern in research on the effects of acidic deposition. The gradual erosion of carbonate stone is the result of two possibly related processes: carbonate stone dissolution (chemical erosion), and the mechanical loss of grains from .
In tropical areas with thick massive limestones, a remarkable and distinctive landscape of jagged hills and narrow gorges completely dominates the landscape. Movement of solution along fractures and joints etches the bedrock and leaves limestone blocks as isolated spires or pinnacles.
The process that occurs during boiling of liquid is energizing of water molecules (H 2 O) to give them excessive energy for excitement to change their form to gas from liquid.
This may occur in eroded limestone areas known as karst topography, which make up only a small percentage of Earth's area. More usual is that the pore spaces of rocks in the subsurface are simply saturated with water — like a kitchen sponge — which can .
5 Weathering, Erosion, and Sedimentary Rocks. . Salt expansion, which works similarly to frost wedging, occurs in areas of high evaporation or near-marine environments. . Limestone occurs in many forms, most of which originate from biological processes.

Limestone pavement, a landform consisting of a flat, incised surface of exposed limestone that resembles an artificial pavement Polje (karst polje, karst field), a large flat specifically karstic plain. The name "polje" derives from South Slavic languages. Doline, also sink or sinkhole, is a closed depression draining underground in karst areas .

A karst can also be found where limestone or other soluble rock layers are present above the ground and exposed to waves, running water or other weathering processes. In some areas, a karst may be found where conditions that created the karst no longer exist. Famous Karst Locations • Ozark Plateau, Ozark Mountains, Missouri and Arkansas, USA
Caves: A cave is a naturally occurring underground hollow or passage, especially one with an opening to the surface of the Earth. Caves often form in limestone areas when underground water dissolves the rock, forming tunnels passages and even large caverns. There are several caves in Barbados, the most famous of which is Harrison's cave.
-The net result is that the calcite dissolves-caves form in limestone; limestone and marble buildings, monuments, statues, etc. weather more rapidly (ACID RAIN accelerates this process)-Ground water is HARD from dissolved minerals (mainly iron and calcium)
Metamorphism is defined as follows: The mineralogical and structural adjustment of solid rocks to physical and chemical conditions that have been imposed at depths below the near surface zones of weathering and diagenesis and which differ from conditions under which the rocks in question originated.
This process occurs at the surface of the buildings or monuments; thus acid rain can easily destroy the details on relief work (e.g., the faces on a statue), but generally does not affect the structural integrity of the building. The degree of damage is determined not only by the acidity of the rainwater, but also by the amount of water flow .
A map showing the density of caves by county within the United States reveals that, for the most part, caves are located within specific areas or regions. Many of these regions share some similarities in the type of rock within the area as well as how water flows through the region.
This type of forest is most commonly found in coastal areas, in situations where limestone of marine origin was lifted above the sea level by tectonic processes. Limestone areas in higher altitudes do exist, particularly in Eastern Java, the Nusa Timur Region and in Irian Jaya (West Papua). The landscape resulting from weathering and the .
The coastal zone: key processes. Three key processes take place in the coastal zone: Erosion - waves can erode the coastline in a similar way to the water in rivers. This usually occurs when the .
Dissolution occurs when rocks and/or minerals are dissolved by water (Fig. 6). The dissolved material is transported away leaving a space in the rock. One consequence of this process is the formation of caves in limestone areas (Fig. 7). rain + carbon dioxide Æ carbonic acid .

British Columbia is blessed with an abundance of world-class karst, particularly in the Rocky Mountains and on Vancouver Island. Other areas of karst development occur on the Queen Charlotte Islands, along the coastal mainland, in the interior mountain ranges, the Cariboo Mountains, and in northwest BC.
A limestone cave or cavern is a natural cavity that is formed underneath the Earth's surface that can range from a few metres to many kilometres in length and depth. Most of the world's caves, including those at the Cradle of Humankind, are formed in porous limestone.
focusing only on the processes that are most important at the global scale (Figure 2). As you might imagine, part of the trick is understanding just what those processes are. Figure 2. A simplified diagram of the global carbon cycle. Pool sizes, shown in blue, are given in petagrams (Pg) of carbon. Fluxes, shown in red, are in Pg per year.
Limestone is added before the heating process in which the glass is formed. The limestone in the glass helps protect it from weathering. . What are the processes that occurs in limestone areas .
Limestone is not found everywhere. It only occurs in areas underlain by sedimentary rocks. Limestone is needed in other areas and is so important that buyers will pay five times the value of the stone in delivery charges so that limestone can be used in their project or process.
Mechanical, or physical, weathering has taken place in limestone landscapes such as the Pennines of Yorkshire. An example is 'freeze-thaw' where water soaks into small fissures and cracks, expands when it freezes in the winter, and physically breaks the limestone.
Chemical weathering can also result from exposure to water. Hydrolysis occurs when silicate minerals react with water so that the mineral recombines with the water molecule to form a new mineral.For example, consider the mineral potassium feldspar. Potassium feldspar is a fairly common mineral and can be found in igneous, metamorphic and sedimentary rocks.
Teachers may prefer to do the activity using ground limestone (available from garden centres) rather than limestone chippings. This has the advantage of speeding up the activity (the colour change occurs in a few minutes rather than an hour or so) but the disadvantage of using a somewhat less familiar material). Context

Karst connotes an assemblage of landforms and a set of processes. most common in carbonate rocks (limestone, dolomite) also occurs in evaporites (salts) also occurs on ice; Distribution of karst in the US. Map source: USGS Open File Report 2004-1352. Learning outcomes: you should be able to:
Today, the volcanoes and great earthquake belts are no longer active, but rivers and streams, wind and rain, and the slow, inexorable alterations of rocks at or near the surface continue to change the face of Texas. The geologic history of Texas, as documented by the rocks, began more than a billion years ago.
