They usually reach Earth's surface when they are entrained (carried along with) within molten material from depth that is erupted onto the earth's surface.

What comes out of a cinder cone volcano?

A cinder cone volcano erupts cinder, or chunks of basaltic lava that develop in lava fountains. These cinders are often filled with bubbles, creating a kind of rock called scoria. Some cinders contain xenoliths, which are chunks of rock that got broken off and carried to the surface without melting and joining the magma. Xenoliths can come from both the crust and from the mantle.


Is it true that only three or four meteorites reach earths surface each year?

No it is not true. Many, many meteorites reach the earth's surface.


What is openings in Earth's crust that allows magma to reach the surface called?

The opening of the crust where magma is allowed to reach to the surface is called a fault line.


What is a rock fragment that becomes enveloped in a larger rock during the larger rocks development and hardening?

A 'xenolith' (Greek: 'foreign rock') is a rock fragment which becomes enveloped in a larger rock during the latter's development and hardening. In geology, the term ''xenolith'' is almost exclusively used to describe inclusions in igneous rock during magma emplacement and eruption. Xenoliths may be engulfed along the margins of a magma chamber, torn loose from the walls of an erupting lava conduit or explosive diatreme or picked up along the base of a flowing lava on Earth's surface. A 'xenocryst' is an individual foreign crystal included within an igneous body. Examples of xenocrysts are quartz crystals in a silica-deficient lava and diamonds within kimberlite diatremes. Although the term xenolith is most commonly associated with igneous inclusions, a broad definition could include rock fragments which have become encased in sedimentary rock. Xenoliths are sometimes found in recovered meteorites.


What does the ozone hole allow to reach Earth's surface?

The ozone hole allows some radiations to reach the earth's surface. These radiations are high energy UV radiations.

What is dalmatian rock?

There is an igneous rock called Orbicular Rhyolite which is formed when lava flows onto the earths surface. It gets the nick name "Dalmatian Rock" from the spots, or orbs on its surface. The orbs form when molten lava reacts with fragments of xenoliths. The main components of Rhyolite are Feldspar and Quartz.
