Igneous rock is one of the three main types of rock formations making up the earth's crust. It is formed primarily through the cooling and subsequent solidification of magma or lava. Igneous rock may also form without any crystallization -- below the Continue Reading...
238 -- 273) Coasts: Define a beach. What is the shore face along a beach? What is littoral drift (long shore sediment transport)? What is difference between Groin and Jetty? Where would you find a tidal inlet? Give an example. What is wave refracti Continue Reading...
Both, ironically, are forms of pressure that also cause heat and changes. Water for instance, is so abundant on earth that it drives much of weathering and erosion. Precipitation, acidic soil water and groundwater dissolve mineral and rocks; serpent Continue Reading...

I think this 20 million dollar process may be replaced with an eco-friendly material based insulator making technique. Even lay people are aware of the many uses of igneous rocks: countertops, floors, tiles, landscaping, construction, sink cleanser, Continue Reading...
This happens as the magma chamber empties and a ring fracture occurs. This collapse often blocks the flow of magma but the heated interior still produces gasses and steam. Often, that steam and other gasses create a lake in the middle of the caldera Continue Reading...

d.). A researcher may determine if a rock sample is sedimentary by examining whether it consists of grains. An igneous (from the Latin word for fire) rock, known as granite, consists of minerals like quartz, mica, and feldspar. "Igneous rocks come fr Continue Reading...
The effects of liquids are not a factor in regional metamorphism as fluids cannot circulate due to the effects of pressure upon the rocks, which seal in the circulation of moisture. Regional metamorphism occurs in areas of heavy tectonic activity, n Continue Reading...
The valley floor itself can experience a variety of topographical changes. As was discussed, the Napa River and other streams deposit clays, shales, and a variety of other river sediments in the valley lowlands, while a historical narrowing of the Continue Reading...
