The strain is accommodated by either rocks sliding past one another, causing earthquakes, or by molten rocks welling up from deep underground to fill the opening space, ultimately leading to volcanic eruptions.

It eroded from igneous rock, which was produced by the solidification of molten magma.

Inability to find rock formations from the period led them to conclude that early Earth was hellishly hot, either entirely molten or subject to such intense asteroid bombardment that any rocks that formed were rapidly remelted.

The spherules, known as microtektites, are droplets of molten rock that were melted and thrown out of the impact crater by the energy of the projectile, or condensed from rock that was vaporized upon impact.

The billion - year cycle of molten rock rising from the core - mantle boundary and falling from the crust — not unlike the motion of globules in a lava lamp — takes form, as do other geologic features of interest.

The study, according to Valley, strengthens the theory of a «cool early Earth,» where temperatures were low enough for liquid water, oceans and a hydrosphere not long after the planet's crust congealed from a sea of molten rock.

The volcano was probably created by a tectonic rift running under west Antarctica, where Earth's crust is being pulled apart and molten rock is welling up from beneath.

Several sites on the near side sampled by Apollo astronauts had rocks enriched with KREEP — for potassium (K), rare earth elements (REE) and phosphorus (P)-- which resists crystallization from magma and hence remains in a molten state until the entire magma ocean has solidified.
