The amount of gravity the moon has.
The earth's mass is increasing slightly. Not much gets out of the gravity well except what we launch, and we are the subject of falling rocks on a 24/7/365 basis.
Yes. Rocks on the moon are similar to volcanic rocks on Earth.
mantle
They brought back moon rocks to earth.
the three major rocks are igneous, sedimentary, and metamorphic rock. igneous- volcanic rocks sedimentary- rocks with layers on top metamorphic- rocks that formed to another rock
thickness 1/8( a mixture of lighter and heavier rocks which were forced out from the mantle by volcanic activity)
They formed as heavier and lighter rocks separated
As the earth formed, the heavier, more dense elements sunk toward the center, while the lighter, less dense ones stayed near the surface. The result was layers of rocks of similar density.

The main theory on the continental divide is that they relate to the plate techonics theory of the Earth's crust. The other theory is the continental drift theory where lighter rocks float on heavier crustal material.
Dark igneous rocks usually have higher amounts of heavier elements such as iron. Light-colored igneous rocks tend to be richer in lighter elements like sodium and aluminum.

To begin with the Earth was like a ball of hot bubbling liquid of rocks made from different elements and compounds. Some rocks were heavier than others. The heavy rocks started to sink and moved towards the center of the earth. Lighter rocks moved towards its surface. This separation of layers took millions of years. The present day Earth comprises the crust, the mantle and the core.
The earth's crust is the outer lighter portion of the continental crust. The crust beneath the ocean iscomosed of heavy, dark volcanic rock. The continental crust is composed mostly of lighter rocks rich in silica such as granite.
