Question: What are the 3 main kinds of rocks?
... the 3 main kinds of rocks? The 3 kinds of rocks are igneous, sedimentary, and metamorphic. Igneous rocks are either glassy, fine grained, coarse grained, or porphyritic. Volcanic rocks sometimes have holes in them from escaping gases (called vesicles). Sometimes the holes are filled with minerals ...

... the north. The Meers fault is part of the Pennsylvanian Frontal Fault System. It stretches from the southeast to the northwest through south central and southwest Oklahoma and into the Texas "Panhandle." The characteristics of the fault are very unusual for the Mid-Continental United States ...
'Water controls weathering type and rate'-How far do you agree with this statement
... chemical and biological. Weathering takes place on exposed rock surfaces, at the junction between regolith and bedrock. Mechanical, chemical and biological weathering each includes several processes and all three types of weathering are at work in all environments, although their relative importance ...

... of the table of chemical elements with an atomic weight of 196.967 and an atomic number of 79. It can be dissolved in a mixture of various hydrochloric and nitric acids. In conclusion, gold is an element of ...
Predicting volcanoes
... the clouds of gasses from an eruption are being dispersed around the globe. Seismographic monitoring is one of the best ways to predict when a volcano eruption will occur. When magma is rising to the surface, it often causes noticeable earthquakes. As the magma nears the surface, the earthquakes ...
The earth is said to be in a state of "dynamic equilibrium." Explain?
... Surface processes include weathering, erosion, and the transportation of sediments, and are responsible for rounded hills, valleys, and places like Kansas. A good local example in your area (Arizona) would be the Grand Canyon. Tectonic forces are causing the uplift of the sedimentary rocks ...
Human Evolution and the Fossil Record
... Rocks and ash created in this manner contain potassium-40, but no argon. As time passes, the potassium-40 decays into argon-40. In the laboratory, the sample is reheated, and since argon-40 is a gas, it is released. The ratio of ...
Diamond Mining and Uses
... of these was found and kimberlite pipes were discovered in the 1980s, construction for the Venetia mine began in 1990. It was fully taken advantage of in 1993. This mine performs open-pit mining, exploring the surface of the area and later digging deeper into the earth. The target floor depth of the ...
