Earth cutaway from core to exosphere. Partially to scale. Travelling to the Earth's center is a popular theme in science fiction. Some subterranean fiction involves traveling to the Earth's center and finding either a hollow Earth or Earth's molten core. Planetary scientist David J. Stevenson suggested sending a probe to the core as a thought ...
The temperature increases towards the center of the Earth, and the higher temperature of the fluid lower down makes it buoyant. This buoyancy is enhanced by chemical separation: As the core cools, some of the molten iron solidifies and is plated to the inner core. In the process, lighter elements are left behind in the fluid, making it lighter.
Earth's inner core is the innermost geologic layer of the planet Earth. It is primarily a solid ball with a radius of about 1,220 km (760 mi), which is about 20% of Earth's radius or 70% of the Moon's radius. [1] [2] There are no samples of the core accessible for direct measurement, as there are for Earth's mantle. [3]
The transition between the inner core and outer core is located approximately 5,150 km (3,200 mi) beneath Earth's surface. Earth's inner core is the innermost geologic layer of the planet Earth . It is primarily a solid ball with a radius of about 1,220 km (760 mi), which is about 19% of Earth's radius [0.7% of volume] or 70% of the Moon 's radius.
Vostok Research Station is around 1,301 kilometres (808 mi) from the Geographic South Pole, at the middle of the East Antarctic Ice Sheet.. Vostok is located near the southern pole of inaccessibility and the south geomagnetic pole, making it one of the optimal places to observe changes in the Earth's magnetosphere.
The internal structure of Earth. Earth's mantle is a layer of silicate rock between the crust and the outer core.It has a mass of 4.01 × 10 24 kg (8.84 × 10 24 lb) and makes up 67% of the mass of Earth. [1]
A core catcher is a device provided to catch the molten core material of a nuclear reactor in case of a nuclear meltdown and prevent it from escaping the containment building. A core catcher is made from a special thermally resistant concrete ceramic to prevent nuclear core material from melting through the core catcher; it also has a cooling ...
AdventureQuest Worlds is a massively multiplayer online role-playing game set in the world of Lore, where players traverse its landscape and engage in quests and battles against various monsters, all while interacting with or alongside other players and non-playable characters (NPCs). When making a character avatar, players can select from the ...
