Earth ScienceAsked by: Lacey Moreno The rhyolite magma chamber beneath YellowstoneYellowstoneThe Yellowstone Caldera, sometimes referred to as the Yellowstone Supervolcano, is a volcanic caldera and supervolcano in Yellowstone National Park in the Western United States. The caldera and most of the park are located in the northwest corner of Wyoming. Will the Yellowstone volcano erupt? Unlikely
I just read news that Antarctica had set a new record high temperature, above 18 °C. How can this be the case if it is currently winter there?
Earth ScienceAsked by: Lacey Moreno What is the record high temperature in Antarctica? The recent extraordinary heatwave in Antarctica appears to have set a new World Record for the largest temperature excess above normal (+38.5 °C / +69.3 °F) ever measured at an established weather station. It “appears to have set a new World Record for
To what extent has the Earth’s surface been geologically mapped?
Earth ScienceAsked by: Twanya Mason What is meant by geological mapping? Definition of geological map A geological map is the representation, about a topographic map, of the different types of rocks that outcrop in the terrestrial area and the types of contacts among them. For distinguishing the rocks colors are used. How do you map an
Can paleomagnetic techniques determine the exact direction of Earth’s magnetic poles in the past, not just their polarity?
Earth ScienceAsked by: Twanya Mason What has paleomagnetic data been used for? This record is preserved by many rocks from the time of their formation. The paleomagnetic data have played an instrumental role in deciphering the history of our planet including a decisive evidence for continental drift and global plate tectonics. What does paleomagnetic measure? Paleomagnetism
Why is seawater saline?
Earth ScienceAsked by: Becca Brown Ocean salt primarily comes from rocks on land and openings in the seafloor. Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Is sea water saline water? Sea water is composed
