What are speleothems answer?
GeologySpeleothems, sometimes referred to as formations or decorations, are cave features formed by the deposition of minerals. The word speleothem is derived from the Greek words spelaion meaning “cave” and thema meaning “deposit”. The speleothems with which most people are familiar are stalactites and stalagmites. What are speleothems? Speleothems are mineral deposits formed from groundwater
What is a plateau mountain?
GeologyPlateau. Mountain is an elevated landform. Plateau is an elevated flat land that is different from the surrounding plains. Mountain generally has a cone-shaped structure. Plateau looks like a large table. What is an example of a plateau mountain? The Yellowstone Plateau in the United States, the Massif Central in France, and the Ethiopian Plateau
What are some common earthquake prediction methods?
GeologySeveral methods have been tested in the effort to learn how to predict earthquakes. Among the more serious methods which have been examined are seismicity changes, changes in seismic wave speed, electrical changes, and groundwater changes. “Seismicity changes” is really a fancy way of saying “foreshocks”. What are the common earthquake prediction methods? When the
Why is cross section important?
GeologyCross-sections are important tools that aid in the interpretation and presentation of geological data, however; they provide only a two-dimensional picture and must be interpreted accordingly. They are most effectively used in conjunction with other illustrative techniques. What does cross section tell you? Cross sections tell physicists how likely particles are to interact in a

How much do geodesic domes cost?
GeologyGeodesic Dome Kits Geodesic kits start at $50,000. This seems like a steal until you realize you’ll need help building it. Most companies will charge $80 per square foot if you do it yourself and up to $200 per square foot for them to build it. How expensive is geodesic dome? The cost varies by
How does heat flow cause changes to Earth?
GeologyMoreover, the way that this works is that convection currents in the mantle (inside the Earth) causes tectonic plates to move when material near the Earth’s core rises, and colder mantle rock sinks. In addition, this movement allows for the creation of many geological features. How does heat flow change Earth’s surface? How does all
What does lava become?
GeologyWhen a volcano erupts, the molten rock (or magma) that comes out of the Earth is called lava. Because lava is so hot (more than 1,100 degrees C, over 2,000 degrees F), it remains molten and flows across the ground until it cools and hardens into rock. Does lava become magma? The distinction between magma
Is Oregon expecting an earthquake?
GeologyIs there going to be a big earthquake in Oregon? Currently, scientists are predicting that there is about a 37 percent chance that a megathrust earthquake of 7.1+ magnitude in this fault zone will occur in the next 50 years. This event will be felt throughout the Pacific Northwest. How likely is earthquake in Oregon?
Is basalt stone porous?
GeologyIs basalt rock porous? Basaltic lavas tend to be fluid and form thin flows that have a considerable amount of primary pore space at the tops and bottoms of the flows. Numerous basalt flows commonly overlap and the flows commonly are separated by soil zones or alluvial material that form permeable zones. Does basalt absorb
