The land around you, no matter where you live, is made of rock. If you live in a place that has good rich soil, the soil itself is finely broken down or weathered rock. People that live in a desert region can easily find rocks on the surface. These rocks lay on a surface of clay that is also a product of weathering rock. Weathering is the process of breaking down …
عرض المزيدSolution Caves Solution or karst caves are the most common type of cave. These caves form by a chemical reaction where groundwater dissolves the rock slowly. Karst caves form mostly in one of two types of rock: carbonates (limestone, dolomite, and marble) and evaporites (gypsum, anhydrite, and halite). Karst begins with rain. Droplets pick up

عرض المزيدThis biochemical extraction and secretion is the main process for forming limestone, the most commonly occurring, non-clastic sedimentary rock. Limestone is mostly made of calcite (CaCO 3) and sometimes includes dolomite (CaMg(CO 3) 2), a close relative. Solid calcite reacts with hydrochloric acid by effervescing or fizzing. Dolomite only ...
عرض المزيدIn some types of chemical weathering the original mineral becomes altered to a different mineral. For example, feldspar is altered—by hydrolysis—to form clay minerals plus some ions in solution. In other cases the minerals dissolve completely, and their components go into solution. For example, calcite (CaCO 3) is soluble in acidic solutions.
عرض المزيدLimestone, a sedimentary rock composed primarily of calcium carbonate (CaCO₃), forms via two predominant pathways: biogenic precipitation and abiogenic precipitation. Understanding these processes necessitates an examination of the relevant chemistry, geological forces, and temporal scales involved.

عرض المزيدCalcite is the major component of limestone (typically more than 95%), and under surface conditions limestone will dissolve to varying degrees (depending on which minerals it has other than calcite), as shown on Figure 10.2.3. Limestone also dissolves at relatively shallow depths underground, forming limestone caves.
عرض المزيدLimestone caves often contain stalagmites as well as stalactites. These structures grow on the floor, with a thick base and a point that looks up towards the cave ceiling.
عرض المزيدSolution weathering is the process by which certain minerals are dissolved by acidic solutions. For example, calcite in limestone is dissolved easily by carbonic acid. Rain that percolates through cracks and fissures in limestone beds dissolves calcite, making wider cracks that can ultimately develop into cave systems. Oxygen.
