Young Earth developed a layered structure under the influence of
gravity and density segregation—the process of differentiation.
The two most common igneous rocks are basalt and granite. Basalt is commonly found _____, and granite is found _____.
on both the ocean floor and continental land; only on the continents.
The three sources that brought young Earth to its melting point were
impact heating, gravitational contraction heating, radioactive decay heating.
When magma solidifies before reaching Earth's surface it is called
intrusive igneous rock,plutonic rock,a pluton.
In a sedimentary rock, poorly sorted, angular grains indicate that
the sediment traveled a short distance.
The layered appearance of foliated metamorphic rocks is due to the
realignment of sheet-structured minerals so that they are perpendicular to compressive forces.
When rock is broken down into smaller and smaller pieces, we say the rock has undergone
Layered sedimentary rocks and foliated metamorphic rocks share similarities because
most foliated metamorphic rocks are derived from layered sedimentary rocks.
