What causes folds and faults?
GeologyWhen the Earth’s crust is pushed together via compression forces, it can experience geological processes called folding and faulting. Folding occurs when the Earth’s crust bends away from a flat surface. A bend upward results in an anticline and a bend downward results in a syncline. What are the causes of folds? The ULTIMATE CAUSE

What is isotopic dating used for?
GeologyRadioactive dating is a method of dating rocks and minerals using radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks. Over 300 naturally-occurring isotopes are known. What does isotopic dating deal with? Isotopic dating of rocks, or the minerals in

How long is the Lechuguilla Cave?
GeologySince 1984, explorers have mapped over 145 miles (233 km) of passages and have pushed the depth of the cave to 1,604 feet (489 m). As of July 2019, Lechuguilla is one of the ten longest caves in the world (one of the four longest in the United States) and the second deepest limestone cave

What type of volcano produces Rhyolite?
GeologyRhyolite usually forms in continental or continent-margin volcanic eruptions where granitic magma reaches the surface. Rhyolite is rarely produced at oceanic eruptions. What is a rhyolitic volcano? Rhyolite caldera complexes are the most explosive of Earth’s volcanoes but often don’t even look like volcanoes. They are usually so explosive when they erupt that they end

What sedimentary rock fizzes in acid?
GeologyLimestoneLimestone is an unusual rock in that it fizzes when dilute acid is placed on its surface. It is the presence of calcium carbonate that is responsible for this. What type of rock reacts with acid? carbonate rocks Some sedimentary rocks are bound together with calcite or dolomite cement. Sandstone, siltstone, and conglomerate sometimes have

How does a lava lamp relate to plate tectonics?
GeologyHeat within the asthenosphere creates convection currents (similar to the currents that can be seen in the lava lamp). These convection currents cause the tectonic plates to move several centimeters per year relative to each other. How does a lava lamp relate to mantle convection and plate tectonics? The Earth’s mantle has convection currents because

How do lava rocks work in a fire pit?
GeologyLava rocks work well in a fire pit because they disperse the flames, spreading the heat and giving the pit an appealing look. Heat coming from the burner goes straight upwards, but if you add a layer of lava rocks to the fire pit, the heat will spread out around the burner. How do you

What is the area filled with groundwater called?
GeologyDetailed Description. The top of the surface where groundwater occurs is called the water table. In the diagram, you can see how the ground below the water table is saturated with water (the saturated zone). Is an underground area filled with groundwater? Groundwater fills in all the empty spaces underground, in what is called the
