Iron is a silver-grey metal that quickly rusts when exposed to air and water. It is responsible for the red colour in many of our rocks and the deep red sands of the Australian deserts. Iron is not usually found in pure form within rocks, instead it is combined with oxygen in ore minerals such as hematite (from the Greek word meaning 'blood ...

Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in the form of a natural crystalline mineral is known as rock salt or halite.Salt is present in vast quantities in seawater.The open ocean has about 35 g (1.2 oz) of solids per liter of sea water, a salinity of 3.5%.. Salt is essential for life in general, and ...

Water (H 2 O) is a polar inorganic compound.At room temperature it is a tasteless and odorless liquid, nearly colorless with a hint of blue.This simplest hydrogen chalcogenide is by far the most studied chemical compound and is described as the "universal solvent" for its ability to dissolve many substances. This allows it to be the "solvent of life": indeed, water as found in nature …

Earth is the third planet from the Sun and the only astronomical object known to harbor life.While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water.About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers.The remaining 29% of Earth's surface is land, consisting of continents and …

A fourth type of foliated metamorphic rock is called slate .Slate exhibits slaty foliation, which is also called cleavage.In geology, cleavage refers to the tendency of a rock to break parallel to the alignment of the tiny mica minerals it is composed of.This means that slate breaks into thin layers, which have economic value as tiles and blackboards.

In addition to the relatively small particles of mineral sediments, there are often larger rocks of various sizes and kinds in wetlands. Whether a massive, continuous layer of bedrock underlying the wetland and forming its foundation, or relatively smaller rocks that are under the water or that protrude above the surface, rocks are a significant abiotic factor in …

During a unit on sedimentary rock, my students create sediment bottles. Students use the sediment bottles to explore the "birth" of sedimentary rocks and relate their observations to the local rivers and streams. Students bring in clear plastic bottles (16-20 oz soda or water bottles) and samples of pebbles, sand, clay, and soil.

The formation of rocks results in three general types of rock formations. Igneous rocks form from magma (intrusive igneous rocks) or lava (extrusive igneous rocks). Sedimentary rocks form from sediments worn away from other rocks. Metamorphic rocks occur when heat and/or pressure impact other rocks.

Granite, limestone, marble, and sandstone are examples of kinds of rock. Geologists divide rocks into three large groups: igneous, metamorphic, and sedimentary. Lava or magma form igneous rock. Changes in pressure or heat create metamorphic rock. Water and wind create sedimentary rock. (Each rock group includes hundreds of different kinds of ...

Life is a quality that distinguishes matter that has biological processes, such as signaling and self-sustaining processes, from that which does not, and is defined by the capacity for growth, reaction to stimuli, metabolism, energy transformation, and reproduction. Various forms of life exist, such as plants, animals, fungi, protists, archaea, and bacteria.

Primary production is the production of organic matter from inorganic carbon sources. This mainly occurs through photosynthesis.The energy incorporated through this process supports life on earth, while the carbon makes up much of the organic matter in living and dead biomass, soil carbon and fossil fuels.It also drives the carbon cycle, which influences global climate via the …
