Measuring the temperature of lava. Why does the lava get so hot? The Earth is roughly a sphere, with a radius of 6,371 km. The chamber in which aluminum was converted to "hot dense matter" via x-ray bombardment. Basalt lavas are the hottest. Lava is indeed very hot, reaching temperatures of 2,200° F or more. Asked by: Judy Answer It is approximately 4000'C at the centre of the Earth. The hottest place on Earth revealed: Researchers find lava deep in the planet's mantle nears 1,600 degrees Celsius. Fiery Hot Lava Planet Weather Forecast: Supersonic Winds and Rocky Rains . But was the planet ever as hot as it is today, when every month the globe seems to be breaking one high-temperature record after another? The hottest spot on Earth has a melting economy. That’s about five times hotter than the hottest lava on Earth. The hottest lava on Earth today is basaltic lava. How hot is the center of the earth? Modern human civilization, with its permanent agriculture and settlements, has developed over just the past 10,000 years or so. The Sun is made up of different gases such as hydrogen and helium. Deep areas in Earth's mantle might be as hot as they were 2.5 billion years ago The hottest-known exoplanet is so hot it rips apart its own molecules. The temperatures of lavas vary depending on their chemical composition. The hottest type of lava, basaltic lava, is also the most common. Temperature increases about 30ºC for every kilometre depth. Lava, the melted rock that shoots out of volcanoes, can flow at temperatures of thousands of degrees Fahrenheit. Hawaiian lava (basalt) is usually around 1100 C. Volcanoes such as Mt.

July was the hottest month ever recorded on the planet. Photograph by R.L. Check out Physics Girl! The core itself is about the size of a dwarf planet, like Pluto. This is true not only in volcanoes but everywhere. Normal lava temperatures reach 750° Celsius. Those ancient climates would have been like nothing our species has ever seen. http://youtube.com/physicsgirlBe cool and SUBSCRIBE! At the center of the large illuminated region there is an ocean of molten rock overlain by an atmosphere of rock vapor. By Ker Than 08 March 2006. Lightning is hotter by a mile! The hottest thing that we know of is the plasma of lightning at several thousand Celsius. Our results imply that a mantle reservoir as hot as those responsible for some Archaean lavas has survived eons of convection in the deep Earth and is still being tapped by mantle plumes. It’s pretty hot down there at the earth’s core and you’ll find this is due to a large amount of iron being kept at very high pressure to create a high temperature. It comes from the Earth's mantle or crust. When asked of the hottest thing that could burn melt and burn all things on earth, a quick response would be the solar systems very own Sun. Located near the borders of Eritrea and Djibouti , the Danakil Depression in Afar is 120 meters below sea level and daytime temperatures soar to a sweltering 50°C (122°F) in the summer (there’s no air conditioning to … It is in 2 parts, with the inner most core about the size of our moon and is thought to have the same density as steel. Different areas of the Sun have varying degrees of hotness. The temperature of lava when it is first ejected from a volcanic vent can vary between 1,300 to 2,200 F..
