12.2: Karst Landscapes, Landforms, and Surface Features

Exokarst is used to describe all features found on the surface of the karst landscape that range from the small-scale to large-scale (e.g., karren to sinkholes to poljes). Endokarst is used to describe all components of underground karst including the smallest cavities, cave formations, erosional features, and large cave passages.

12.1: Karst Landscapes and Systems

A critical requirement for the development of karst is water. Without water there would be no karst or caves! Carbon-dioxide (CO 2) is another key component as it dissolves in water forming a weak carbonic acid solution (H 2 CO 3) as shown below. This carbonic acid reacts with the solid limestone (predominately CaCO 3) to form the ions …

Chemical Weathering – Definition, Processes and Types

It the process by which the rocks are dissolved when exposed to rainwater. Limestone and rock salts are particularly the rocks that form solvent solutions when exposed to rainwater, surface waters, or even ground water. Upon dissolving, the minerals in the rocks become ion solutions in the water which are then washed away.

The limestone requirement is about 100 kg per tonne of liquid steel produced.

5.2: Weathering and Erosion

The dissolved substances may later precipitate into chemical sedimentary rocks like evaporite and limestone, as well as amorphous silica or chert nodules. Dissolution Figure (PageIndex{1}): In this rock, a pyrite cube has dissolved (as seen with the negative "corner" impression in the rock), leaving behind small specks of gold.

16.13: Acid Rain

The damage that acid rain does to limestone and marble buildings and sculptures is due to a classic acid–base reaction. Marble and limestone both consist of calcium carbonate (CaCO 3), a salt derived from the weak acid H 2 CO 3. The reaction of a strong acid with a salt of a weak acid goes to completion.

The Rock Cycle

There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming —that are part of the rock cycle.

Describe carbonation weathering.

This is known as carbonation. This occurs when slightly acidic (carbonic) rain or seawater comes into contact with sedimentary rock, such as limestone or chalk, it causes it to dissolve. A chemical reaction occurs between the acidic water and the calcium carbonate and forms calcium bicarbonate. This is soluble and is carried away in solution.

How Limestone is Formed

Limestone has a lot of different industrial uses and can be mined and processed for those reasons as a raw material. It can also be used in agriculture, the environment and many other areas. As little as 10 years ago, crushed limestone was about 68% of all crushed rock produced within the country. It is prevalent in places you wouldn't even ...

Processes of Chemical Weathering

Solution 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.
