tidal heating-the result of the enormous gravity field of jupiter
the enormous gravity field of jupiter
7. what is the gutenberg discontinuity and where is located?
is a boundary making a change of material from metallic iron nickel to stony silicate material and changes state between the liquid outer core and the solid mantle, and it is located at 2900 km.
it is a phase boundary between materials of the same composition but different state. it is a zone where the rocks change from all liquid in the outer core through a liquid-solid mix to all solid in the inner core. is located at 5100.
muga bat metalezko burdina , nikela material aldaketa bat likido kanpoaldeko core eta mantu solidoen arteko material silikato eta aldaketa egoera STONY egiten da , eta da, 2900 km
8. how was the solar system formed?
formed by accretion of material
Giant molecular cloud of gas and dust which collapsed under gravity

9. what is a seamount?
a submarine basalt volcano rising at least 1000 km above the ocean floor without reaching sea levels.
submarine basalt volcano
10. what are the processes occurring at a convergent oceanic-oceanic plate boundary?
partial melting of the oceanic crust/ volcanic activity creating volcanic islands arc/ the metamorphisation of the rocks due to high temperature and pressure
volcanic activity/partial melting/metamorphosis

14. what is the lower mantle characteristics?
it is located from 2900 km to 700km, it consists of the the same type of silicate material as the stony meteorite. it is solid because s waves can travel through it and p waves increase in velocity.
is 'n grens om 'n verandering van materiaal uit metaal yster nikkel om silikaat materiaal en veranderinge staat klipperige tussen die vloeistof buitekern en die soliede mantel, maar dit is geleë op 2900 km .
15. how are pillow lavas formed?
Formada por la erupción de lava bajo el agua , el exterior de cada forma de almohada se enfría rápidamente. Cada almohada se enfría en capas .
Formed by eruption of lava under water, the outside of each pillow shape cooled quickly. Each pillow cooled in layers.
Formou por erupção de lava sob a água , a parte externa de cada travesseiro forma resfriado rapidamente
16. how are fold mountains formed?
they are formed due to compression of the continental crust and the sediments scrapped off the subducting plate
they are formed due to tension of the continental crust and the sediments scrapped off the subducting plate

18. what are comets?
rocky objects which failed to form a planet
a celestial object consisting of a nucleus of ice and dust and, when near the sun, a ‘tail’ of gas and dust particles pointing away from the sun.
fragments of rock which fall to earth from space
