How does mineral growth occur? How are humans influencing the nitrogen cycle? How does evaporation occur? How does nitrogen enter the food chain? How does eutrophication affect the oxygen level in water? How do new minerals grow in existing rocks?
Is magma a mineral? How are metamorphic rocks different from igneous and sedimentary rocks? How is calcite formed? What happens to minerals when a rock becomes metamorphic? How do evaporite sedimentary rocks form? When do metamorphic rocks form?
The discovery of a rare mineral (reidite) at the Woodleigh meteorite impact structure in Western Australia waspublishedthis week by Curtin University honours student Morgan Cox and colleagues. Reidite – and other minerals – are sometimes formed when meteorites crash into Earth. This takes a parti...
As it moves, it leaves behind suspended material and may carry away mineral matter in solution, a process called leaching. On sloping land, water distributes material laterally (sideways) through the soil. 3. According to paragraph 4, water passing through the soil can affect the soil’s ...
Insubductionzones, where tectonic plates converge, carbon-bearing rocks are forced deep into the Earth’s mantle. The extreme pressure and heat in these zones can facilitate diamond formation. Subduction zone diamonds often contain distinct mineral inclusions, offering clues about the deep Earth environ...
In much the same way, when geologists are trying to track down specific mineral resources, they need to understand the history of the deposits and how they were formed. This knowledge allows us to make educated guesses on where to find valuable mineral resources. In 'normal' rocks, valuable...
Process:Hot, mineral-rich water reacts with rocks, altering their mineralogy and texture. Resulting Rocks:Serpentinite: From ultramafic rocks, formed through serpentinization. Example:Occurs at mid-ocean ridges where seawater interacts with hot basalt. ...

and in many parts of the Earth is highly seasonal. Water that enters the soil during heavy rainfall and snowmelt moves down through the soil. As it moves, it leaves behind suspended material and may carry away mineral matter in solution, a process called leaching. On sloping land, water di...
Extrusive or volcanic rocks are formed when the magma erupted through the upper layers and crystallised by rapid cooling at the surface of the Earth. The fine grained texture of these rocks i.e. the relatively small size of the component mineral grains emphasizes the rapid rate of cooling of ...
