Do you ever wonder why one river is straight and flows quickly while another meanders along curves and seems to be slow and peaceful, or how the mountains were formed? Geology is the study of the earth, its materials, and the processes acting upon them. It includes the study of rocks and minerals; and their formation, weathering, and metamorphosis. So, when you need an answer to a question about rivers, mountains, volcanoes, rock cycles, plate tectonics, or other geological aspects, our Geology category is the place to ask it.
It's not really possible to answer that, as there are so many. Itis also dependent on your definition of mineral. Some are quartz,feldspar, and horneblende.
Creep is the slow mass movement of soil particles down a slope. Itis so slow that we do not see it happen. Creep is often shown inthe form of tilted objects along the slope.
Mountain-building is a result of continental collision, sodestructive plate boundaries. One plate is destroyed by subductionbelow the other, which undergoes compression, buckling and upliftas the collision continues. This is happening at present in Asia,raising the Himalayan Mountains.
Five quarries that I know of are in Kelowna, Kimbereley, Renefrew,Salmo and Revelstoke.
Kimberlite pipes are typically quarried using open pit mines.
Minerals crystallize out from the water surrounding the grains andact as cement.
A volcanic crater is a generally circular shaped depression.
Radium is a decay product of uranium and is constantly beingproduced. U-238 has a half-life of about 4.5 billion years, sothere's still quite a bit left of the original amount on Earth.
ya it may be possible that by the using role scoper results in soilerosion
This is due to different soil compositions.
It didn't really have a name, but there had been no real scientifictheory and most people's ideas were based on stories from theBible.
Well lets see there is black carbon,carbon dioxide emissions and draining rivers if you need help with anything else don't hesitate to ask
It can if exposed to the requisite conditions and circumstances ofweathering and erosion.

The ground drinks the water and air underneath the surface forces its way up.
The common term is rock hound. If the collector collects precious stones, gemologist could fit.
The thinner but more dense crust of the earth is the Oceanic Crust.
Amateur geology (known as rockhounding in the United States and Canada ) is the recreational study and hobby of collecting rock s and mineral specimens from their natural environment. The firstamateur geologists were prospector s looking for valuable minerals and gemstone s for...

Mars haz a thin atmosphere, but its gravity is very related to that of Earth, making colonization a possible thing in the future.
Vesuvius is about 1,000 feet deep and 2,000 feet across.
Both. While most of the landmass of Earth is made of igneous andmetamorphic rocks, most of the rocks that we can actually see (i.e.those on the surface) are sedimentary. Sedimentary rocks are formedfrom deposition by forces like rivers, waves and glaciers.Sediment, however, comes from eroded...
It helps the soil hold more rainfall so there will be less runoff and ruin the crops.
First, pebbles can be the result of larger rocks breaking up. Someof these large rocks were bedrock under a huge continent. A longtime ago, the continents used to be one and then drifted apart totheir current locations and are still drifting to this day. Duringthis process, the "plates" under the...
Fossils are not found in water, but rather in the sediment depositswhich includes the bottom of a body of water. Fossils areespecially prevalent in shallow marine environments where they maybecome well preserved.
Mica is an interesting silicate mineral. The silicate series is:quartz --> mica --> asbestos. Quartz possesses three dimensional Si-O bonds which results in acrystal that is strong in every direction. Consequently, quartz isan exceptionally hard mineral. Mica, on the other hand, only has strong...

Geologists study the Earths surface
Otavia antiqua, a sponge has been dated to ~760 Ma.
Infertile soils lack abundant plant nutrients, especially foragricultural crops. It doesn't mean they're unsuitable for plantgrowth, but the only plants that naturally grow on them are thosethat can either do with few nutrients, or can get their nutrientsfrom pools that are unavailable to most...
One of the most common events that causes the rapid cooling of an igneous rock is its collision with a water-based object. This is included but not limited to bodies of water, icebergs, and snow. The rapid cooling causes air bubbles to be trapped within the rapidly hardening rock, thus resulting in...
The size and shape of a mineral is its form.
Typically a quiet eruption means that the magma being forced ontothe surface is low in silicates and gases. This typically meansthat it would be basaltic and slow moving like the lava flows thatcan be observed in Hawai'i. A common danger to anybody near avolcano could be poisonous gases.
By fossilisation and permineralisation. . Fossilisation is caused by layers upon layers of sedimentburying the bones. As the layers of sediment above the buried bonesincreases, so does the pressure on the layers of sediment lowerdown. The pressure becomes so great that the bones and thesedimentary...
Photosynthetic bacteria in the form of stromatolites (essentially sedimentary rocks formed of them) found in Australia. They date back to 3.5 billion years..
Stalactites grow downwards (hang down); Stalagmites grow upwards.How to remember the difference: Stalactites "hold tight" to theceiling.
Rope. You can lay it in a line to explore, and find your way back to where you started, over and over, without becoming confused in the dark. (A blind person would have the advantage here.) You can check out drops/passages and be able to come back up again. (Better make that a goodly long chunk of...
Where oceanic lithospheric plates converge or collide, the older, denser, and colder oceanic plate will move underneath the less dense oceanic plate. This is called subduction. The subducting oceanic plate will basically flow slowly downward at an angle as a slab of rock until heating from friction...
We drive our cars/Humans live on the layer called the crust. Earthis made up of four layers, but we still drive our cars/Live on themost outer layer, called the crust.
NADH is the primary electron and oxygen is theterminal electron acceptor in the aerobic membrane bound electron transport chain. Theoverall electron transfer reactions can be described by the reaction 2 NADH + 2H+ + O2 --> 2 NAD+ + 2 H2O If the above reaction takes place in an aqueoussolution at...
Pumice rocks are found where volcanoes are. Pumice is a volcanic rock. It is formed from lava. However, you should know that not all volcanic eruptions produce pumice.
Crystal is a type of glass. It contains lead oxide whereas cheapglass does not. This makes it rather heavier than cheap glass, sizefor size. It also looks 'sparkly'. The number 8 is used in variousways by many manufacturers.
There is the Crust, Mantle, Outer core, and Inner core. There isn'treally much to them. They are just the layers of the Earth
Some are studied and put in museums and the certain fossils are now oils and natural gases
Cotton does not produce well in soil of high organic matter. Alighter sandier soil is better for cotton. Cotton can alsowithstand high temperatures and loves full sunlight during itsgrowing season. Cotton is grown on different types of soils, suchas sandy loam, clay loam, black cotton soil, alluvial...
A colliding plate boundary is the same thing as a convergent boundary. It occurs when two plates collide, forming mountains and volcanoes.
Yes, trees are good for the soil

Organisms in theground consume organic matter and deposit theremnants as nutrients and minerals in the soil in a form that plantlife can more easily absorb. Larger organisms, like small animals,burrow in the soil which increases the airiness of the soil.
A local oscillator can be a crystal oscillator.
No, the rock cycle does not have to start from the sedimentary rock
People erosion is when the soles of peoples shoes where down the rocks that they are walking on.
Surface wave cause the most damage during an earthquake.
Coal and oil are fairly cheap and abundant fuels, and deposits ofthese range practically from pole to pole around the globe. Manynations employ extraction technology, and those that don't purchaseoil (in particular) as fuel for transportation. So any place anairplane flies or a car, truck, or train...
Mean surface temperature over period duration 16.5 °C is theclosest I could find.
There are four main processes that contribute to erosion - Chemical Weathering, Biological Weathering, Exfoliation, andFreeze-Thaw
Orthoclase feldspar can be found in granite rock as the white or pinkish appearing crystals.
typically 2 things can happen: 1. the magma rises up and solidify s to become hard rock, so it is rebuilding the plate. This happens at on end of the plate, on the other side the plate is being melted away because its being forced into the magma. 2. volcano's form and earthquakes occur.
At one atmoshere pressure, water boils at 212 degrees fahrenheit, or 100 degrees celsius, theoretically you could heat a soil sample higher than that. It depends on the heat source. If you are speaking of temperatures found in nature, lava or magma is hotter than water, but can contain water vapor...
In nature, a well formed crystal that exhibits textbook shape with well formed faces, straight lines, and sharp points is referred to as euhedral. Many crystals could be considered euhedral but not perfect. A naturally occurring perfect crystal would be the next thing to a complete impossibility due...

Yes first is the crust which is made of rocks then from 30km is themantle which is a solid, but it can still flow, then from 2900km isthe core a liquid with a temperature of 3700 degrees C to 4300degrees C. Finally, at 5200km and at temperatures of 4300 degrees Cplus is the inner core, which is a...
Anywhere someone will pay him/her to examine some promising exposed sedimentary rock. Or in a laboratory, examining and testing fossilized ancient life forms. Or in an office, writing papers, doing research, and theorizing about ancient life. Or in a classroom, teaching paleontology to anyone that...
Mt. Lassen is a lava dome type of volcano. The domes of lava domevolcanoes grows from within, and commonly occur within the cratersor on the flanks of large composite volcanoes.
It divides Britain into hard and softer rock types. The softerrocks in the south-east erode faster. In the north west are olderharder rocks such as granite and basalt.
Most hard shelled organisms didn't develop until the Cambrian. Soft-bodied organisms are much less likely to survive as fossils.
It is not generally thought that any of the dinosaurs could survive an ice age unless they were able to travel to warmer areas where food was available. Woolly Mammoths were not dinosaurs but mammals.
The soft rock gently erodes over a period of years mainly through wind.
It actually depends on what type. If you want to be a paleozooologist for example you need to learn paleontology(if any), geology earth sciences, zooology, physics, and chemistry and if ou want to be a micropaleontologist you would need to learn paleontology, geology, earth sciences, microbiology,...
The fossil record reveals relatively gradual changes in speciesover time. For example, the earliest horses had three toes and acurved spine, and were quite small. Over millions of years theouter toes migrated up the leg and fused with the leg bone. Theteeth changed from browsing on leaves and twigs...
A physical feature formed by volcanic eruption is an island. TheHawaiian Islands consist of a chain of such landforms.
Oceanic crusts; the Mid-Atlantic Ridge and East Pacific Rise at zones of seafloor spreading and crustal extensions.
The vadose / unsaturated zone and the phreatic / saturated zone have the water table / phreatic surface as their boundaries.
Igneous rock is formed when magma cools and solidifies Magma can be forced into rocks, blown out in volcanic explosions

Impatiens, Hydrangea, sunflowers and peonies are the plants whichneeded a neutral pH soil.
Marble is made up of interlocking crystals that fit together perfectly like a jigsaw, this makes it harder to break so therefore it is stronger. Limestone is made up of calcite grain that have been stuck together so they don't actually fit together properly.
The Mantle of the Earth is the thickest layer, and while solid, contains elements that cause it to be pliable and flowing due to extreme heat and pressure. It undergoes motions similar to boiling water, known as convection. Convection of the mantle is expressed at the surface through the motions of...
