What are the hoodoos in Utah?
GeologyWhat are hoodoos in Utah? The hoodoos we are talking about are tall skinny shafts of rock that protrude from the bottom of arid basins. Hoodoos are most commonly found in the High Plateaus region of the Colorado Plateau and in the Badlands regions of the Northern Great Plains. Why is it called hoodoo? The
What is the topography of the ocean floor?
GeologyScience has established that the topography of the ocean floor is similar to the ground topography with features such as valleys, mountains, and plateaus. Three quarters of the Earth consists of ocean water. All these details are incorporated on underwater topography maps. What is the topographic of ocean floor called? The topography of the ocean
Why is the ocean not homogeneous and stratified?
GeologyBecause the surface and deep ocean layers are of very different densities (due to salt content and temperature), these layers of the ocean do not mix easily. The resistance of two water bodies with different densities to mix is called stratification. Why are the oceans stratified? The ocean is stratified due to differences in density,
How was the geologic time scale developed quizlet?
GeologyScientists first developed the geologic time scale by studying rock layers and index fossils worldwide. With this information, scientists placed Earth’s rock layers in order by relative age. Later, radioactive dating helped determine the absolute age of the divisions in the geologic time scale. How was the geologic time scale developed? The geologic time scale
How are fossils classified?
GeologyFossils can be placed into four main groups based on the way they formed: impression, mineralised, trace and organic. How are fossil records classified? The interpretation of the fossil record requires describing fossils, classifying them to place them in a biological context, and determining their age to give them chronological context. Fossil classification follows the
What is the population of the Columbia Plateau?
GeologyDo people live in the Columbia Plateau? Population centers are widely dispersed in the ecoregion with only one metropolitan area, Boise, Idaho, exceeding 100,000 in population. What is the largest city in the Columbia Plateau? Major Cities The city of Walla Walla is located in the heart of the Columbia Plateau. What is Columbia Plateau
Do Rocks Have streak?
GeologyStreak Plates A mineral’s streak is the color it has when ground to a powder. Some minerals that occur in a range of colors always have the same streak. As a result, streak is considered a more stable indicator than the color of the solid rock. What does it mean when a rock has a
How do volcanoes affect the 4 spheres?
GeologyVolcanoes affect the spheres: Biosphere- Plant and animal population, soil fertility, damage human property. Atmosphere-release ash and gases, affects climate and weather conditions. Hydrosphere- warmer and more acidic oceans, melting ice bodies, acid rain and soil. How does a volcano affect the spheres? Volcanoes (events of the geosphere) release a large amount of carbon dioxide
What fault runs through Searles Valley?
GeologyThe Ash Hill fault (mostly right-lateral strike slip) transfers strain into the northern con- tinuation of the Searles Valley zone, via a complex array of hanging-wall normal and strike-slip faults. What fault line is Searles Valley on? Garlock Fault The fault continues on to the Garlock Fault about 15 miles southeast of Ridgecrest, just past
How much damage did Mt Pinatubo cause?
GeologyThe eruption cost $700 million in damage, $100 million of which was damage to 16 aircraft flying at the time of the eruption and $250 million in property with the rest a combination of agriculture, forestry and land. How destructive was Mount Pinatubo? Nearly every bridge within 30 km (19 mi) of Mount Pinatubo was
