  2. Geothermal gradient - Wikipedia

    en.wikipedia.org/wiki/Geothermal_gradient

    Earth cutaway from core to exosphere Geothermal drill machine in Wisconsin, USA. Temperature within Earth increases with depth. Highly viscous or partially molten rock at temperatures between 650 and 1,200 °C (1,200 and 2,200 °F) are found at the margins of tectonic plates, increasing the geothermal gradient in the vicinity, but only the outer core is postulated to exist in a molten or fluid ...

  3. Thermosphere - Wikipedia

    en.wikipedia.org/wiki/Thermosphere

    In the exosphere, beginning at about 600 km (375 mi) above sea level, the atmosphere turns into space, although, by the judging criteria set for the definition of the Kármán line (100 km), most of the thermosphere is part of space. The border between the thermosphere and exosphere is known as the thermopause.

  4. Earthquake weather - Wikipedia

    en.wikipedia.org/wiki/Earthquake_weather

    Some recent research has found a correlation between a sudden relative spike in atmospheric temperature 2–5 days before an earthquake. It is speculated that this rise is caused by the movement of ions within the Earth's crust, related to an oncoming earthquake. Furthermore, this relative temperature change would not cause any single ...

  5. Earth's internal heat budget - Wikipedia

    en.wikipedia.org/wiki/Earth's_internal_heat_budget

    Cross section of the Earth showing its main divisions and their approximate contributions to Earth's total internal heat flow to the surface, and the dominant heat transport mechanisms within Earth. Estimates of the total heat flow from Earth's interior to surface span a range of 43 to 49 terawatts (TW) (a terawatt is 10 12 watts). [13]

  6. Atmosphere of Earth - Wikipedia

    en.wikipedia.org/wiki/Atmosphere_of_Earth

    Total atmospheric mass is 5.1480 × 10 18 kg (1.13494 × 10 19 lb), [36] about 2.5% less than would be inferred from the average sea-level pressure and Earth's area of 51007.2 megahectares, this portion being displaced by Earth's mountainous terrain. Atmospheric pressure is the total weight of the air above unit area at the point where the ...

    Taiwan is no stranger to powerful earthquakes yet their toll on the high-tech island's 23 million residents has been relatively contained thanks to its excellent earthquake preparedness, experts say.

  8. Lapse rate - Wikipedia

    en.wikipedia.org/wiki/Lapse_rate

    It varies with the temperature and pressure of the parcel and is often in the range 3.6 to 9.2 °C/km (2 to 5 °F/1000 ft), as obtained from the International Civil Aviation Organization (ICAO). The environmental lapse rate is the decrease in temperature of air with altitude for a specific time and place (see below). It can be highly variable ...

  9. It's not surprising that people by the epicenter near Barstow felt the strongest jolt. But in L.A. Basin, some felt nothing, while others reported swaying for 15 seconds.
