STRUCTURE

 Answer: The inner most layer of the earth is called the “Core or Barysphere”. It is otherwise known as NIFE, because of the presence of Nickel and Ferrous (iron). This layer produces earth's magnetic field.


Seismographs are instruments used to record the motion of the ground during an earthquake. They are installed in the ground throughout the world and operated as part of a seismographic network. The earliest "seismoscope" was invented by the Chinese philosopher Chang Heng in A.D. 132.
X-stics Of Lithosphere
- crystalline rock- imetengenezwa kwa vipande vidogo vidogo
- brittle rock - easy to be broken
- hard
Isostatic Adjustment(Isostasy)
is how lethosphere float upon Asthenosphere

Ultrabasic Rocks
means to igneous rocks containing little or no feldspar and characterized essentially by the abundance of one or more common mafic minerals such as olivine, pyroxene, and amphibole
The ionosphere (/aɪˈɒnəˌsfɪər/) is the ionized part of Earth's upper atmosphere, from about 48 km (30 mi) to 965 km (600 mi) altitude, a region that includes the thermosphere and parts of the mesosphere and exosphere. The ionosphere is ionized by solar radiation.



Forms Of Igneous Rock



Intrusive Earth Crust(plutonic rock)
are igneous rock formed from magma (molten rock) when cooled within the Earth's crust
Extrusive Earth Crust(plutonic rock)
are igneous rock formed from magma (molten rock) when cooled out of the Earth's crust and called larva


Volcanism (or volcanicity or Volcanic Eruption) is the phenomenon of eruption of molten rock (magma) onto the surface of the Earth
