The joints in a massive limestone area are important because they form zones of weakness in the rock, which are attacked by acidic rainwater and chemically weathered. Coral limestones Perhaps the type of limestone that many people think of first is the coral reef, which can be seen growing in the world's warmer, shallow ocean margins.

Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%). It is the most common nonsiliciclastic (sandstone and shale are common siliciclastic rocks) sedimentary rock. Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite).

Dolines are indentations in the surface of the ground which are formed when the roof of a small underground cave falls in. Dry valleys, such as Cheddar Gorge, were formed in periglacial times when the ground froze. As the land was frozen rivers ran over the surface of .

Limestone is one of the most common sedimentary rocks found in New Zealand. Eyecatching features such as caves, sinkholes and spectacular skyline landscapes are often associated with limestone formations. These landforms have developed through the interaction of rocks, water and climate.

A cave is formed where there is bedrock of karst, or limestone. The water, carrying on its chemical reactions travel through cracks in the limestone, slowly dissolving the rock and enlarging the crevice. The runoff descends to the water table, the level of whatever river or lake is closest. More erosion drops the water level more.

The chemical and physical properties of limestone, especially when reasonably pure, make it highly sought after for hundreds of everyday uses. With salt and coal, it formed the main feedstock for the chemical industry until about 1914.

Limestone is a type of rock that is made up of bits of animal shells. Over millions of years these shells collected on the ocean floor. As layers of shells and mud built up, the lower layers slowly hardened into limestone.

In particular, limestone is weathered by rainwater containing dissolved CO2, (this process is sometimes called carbonation). Hydrolysis the breakdown of rock by acidic water to produce clay and soluble salts. Oxidation the breakdown of rock by oxygen and water, often giving ironrich rocks a rustycoloured weathered surface.

Sedimentary Rock. Sedimentary rocks form from the broken pieces of other rocks or from the accumulation of the hard body parts of marine organisms. Now here's an important concept to remember : sedimentary rocks can form from all the other rock types – igneous rocks, metamorphic rocks and other sedimentary rocks.
