Water is an amazing compound without it life on Earth would not exist. It also plays a key role in the formation of certain types of sedimentary rocks. These rocks are often referred to as evaporates. Minerals are common in water as it evaporates the...

Clouds are formed when water vapor evaporating from the surface of the Earth condenses around microscopic particles in the atmosphere. When warm air meets colder air, this triggers the condensation process. This simply means that instead of vapor, the water or, in some cases ice...

The rock cycle deals with the changes that rocks undergo over time due to natural influences of weathering, erosion, pressure, and heat. While short-term changes may not be noticeable even in one’s life time over millions of years these changes are often quite extraordinary...

Temperate soils exist under all types of conditions, including within forests, rain forests and in grasslands, but all have several key things in common. Temperate soils have a rich upper level that is high in minerals and nutrients, and in all cases micro-organisms work to...

Metamorphic rocks are all created by the forces of pressure and heat. Generally they are working together altering the chemical composition of rocks. Despite the same forces at work not every rock ends up with the same texture. Instead metamorphic rocks have two texture groups...
Why coal is an organic sedimentary rock
By: Retha Boswell
Organic sedimentary rocks are one of three types of sedimentary rocks, along with clastic sedimentary rocks and chemical sedimentary rocks. Coal is an organic sedimentary rock. Like other organic sedimentary rocks, coal is made from particles of formerly living things, called organic matter. Peat, lignite...

Sedimentary rocks are the most common rock type found on the planet comprising nearly 70 percent of all rocks. As a result they are immensely important. From unlocking historical secrets to providing the power needed to sustain the modern world these rocks are critical to...

Minerals are the fundamental building blocks of all rocks on Earth, and therefore the study of these minerals is the key to understanding the science of Earth. By definition, minerals are “naturally occurring, crystalline solid substances, of inorganic origin, with specific chemical compositions.&rdquo...

Polar soils are of course found at the poles–that is, in the Arctic in the north as well as the Antarctic in the south. These regions include the continents of Antarctica, Alaska, northern Canada, Greenland, Norden (Lower Saxony, Germany), and the northern USSR. Permafrost...
How do coral reefs form?
By: Jose Juan Gutierrez
Coral reefs are marine structures made of calcium carbonate (CaCO3) secreted by stony corals and other marine species living in the reef. Corals are colonial organisms composed of hundreds of thousands of individual animals known as polyps, which cluster in groups. Polyps secrete calcium carbonate...
