When the volcanic eruption takes space the magma is trusted out of the vents with the release of the gas and the pressure that is build up in the rocks and the by the hot and gas are also ejected with the magma out of the earth that forms lava on the earth surface.
<u>This lava as when it cools forms many forms of igneous rocks as it has originated from the fire. As there is about 700 type of igneous rocks on earth. The extrusive and the intrusive forms are common and the hyper-basalt.</u>
surfaces dramatically altered during the heavy bombardment
Jovian Planets:
formed in a region of the solar system with lower orbital speeds.
accreted from icy planetesimals.
formed in regions cold enough for water to freeze.
ejected icy planetesimals that are now Oort cloud comets.
Explanation:
The rocks planet or the terrestrial planet are those that are ion and rock contents as compared to the gases giants that are made up of helium and hydrogen gases.
The terrestrial planet has few moons, as compared to the Jovian planets that have a large number of moons and icy cold regions where water has frozen or dried up.
They have the primary atmosphere as compared to the terrestrial planets that have the secondary atmosphere. The jovian are made form the Oort cloud while the terrestrial has been altered by the heavy bombardment.
