Where are Synclines found?
GeologySynclines are typically a downward fold (synform), termed a synformal syncline (i.e. a trough), but synclines that point upwards can be found when strata have been overturned and folded (an antiformal syncline). Where can you find syncline? def. Syncline: A fold in a sequence of rock layers in which the younger rock layers are found
Where are cinder cone volcanoes found in the world?
GeologyCinder cones are found in many parts of the world, including: Australia, Canada, Chile, France, Iceland, Italy, Japan, Mexico, New Zealand, Peru, the Philippines, Russia, Spain (Canary Islands), Turkey, and the United States. Where are cinder cone volcanoes mostly found in the world? Cinder cones are commonly found on the flanks of shield volcanoes, stratovolcanoes,
What is an anticline in geology?
GeologyAn anticline is a structural trap formed by the folding of rock strata into an arch-like shape. The rock layers in an anticlinal trap were originally laid down horizontally and then earth movement caused it to fold into an arch-like shape called an anticline. What does anticline mean in geology? An anticline is a fold
How did ammonites go extinct?
GeologyWhy did ammonites go extinct? At the end of the Cretaceous Period, an asteroid colliding with Earth brought on a global mass extinction. A lingering impact winter halted photosynthesis on land and in the oceans, which had a major impact on food availability and was devastating for ammonites. When did ammonites go extinct? about 66
What type of rock is serpentine found in?
Geologymetamorphic rockmetamorphic rock that forms at tectonic plate boundaries deep within the Earth. What kind of rock is serpentine? Serpentine is considered by geoscientists to be the metamorphosed remains of magnesium-rich igneous rocks, most commonly the rock peridotite, from the earth’s mantle. The mantle is a thick layer of rock just below the earth’s crust.
What are earthquakes caused by?
GeologyEarthquakes are the result of sudden movement along faults within the Earth. The movement releases stored-up ‘elastic strain’ energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake. What is the main cause of earthquakes? Earthquakes are usually caused when underground rock suddenly breaks and there
What would happen if the global conveyor belt shut down?
GeologyIf ocean currents were to stop, climate could change quite significantly, particularly in Europe and countries in the North Atlantic. In these countries, temperatures would drop, affecting humans as well as plants and animals. In turn, economies could also be affected, particularly those that involve agriculture. What will happen if the global conveyor belt stops?
What are tectonic plates GCSE?
GeologyTectonic plates are sections of the Earth’s solid crust that “float” on top of the mantle. The mantle contains hot molten rock (magma) heated by energy from the earth’s core. The earth’s crust is made up of seven main tectonic plates and numerous smaller plates. What is a tectonic plate Bitesize? Tectonic plates are pieces
What are two radioactive isotopes that are useful for dating rocks that are older than 10 million years?
GeologyScientists usually use the potassium-argon method to date rocks that are older than about 1 million years. Uranium-238 is also used for radiometric dating. What radioactive isotope is best used for dating rocks that are millions of years old? isotope carbon-14 The best-known radiometric dating method involves the isotope carbon-14, with a half life of
How did the Llano Uplift form?
GeologyCreation of the Area When the surrounding area of younger sedimentary rocks eroded away, it left behind granite at the heart of the uplift. Along with the rest of the Texas Hill Country, the Llano Uplift also rose in elevation during the Cenozoic when the Balcones Fault shifted, lifting the area to the west. What
