There are many different compositions of meteorites. The meteorites that are thought to be analogous in composition to the Earth's core are made of iron.
The density of the continental (granitic) lithosphere is lower than oceanic (basaltic) lithosphere. Consequently, due to buoyancy, the continental crust rides above the oceanic lithosphere and thus is not subducted. However, it is thought that pieces of the continental lithosphere break off and are subducted along with the oceanic lithosphere.
When oceanic lithosphere and continental lithosphere collide, the continental lithosphere may be obducted over the oceanic lithosphere or the oceanic lithosphere may be subducted under the continental lithosphere. The latter is thought to be more common. This subduction and obduction generally results in tectonic activity such as volcanoes and earthquakes.

I thought that they are all glass.
Paragraph is based on one thought or one idea. However, a composition made up of on the paragraphs.

Yes, this is because many meteorites derive from bodies that formed and differentiated (like the Earth) early on in the formation of the solar system but were then shattered by impacts, exposing their core material. This material is thought to be an analogue for the composition of Earth's interior.

The latter is thought to be more common. This subduction and obduction generally results in tectonic activity such as volcanoes and earthquakes.

He saw what he thought was a beautiful composition and painted it.
Jupiter is composed of mostly liquid metallic Hydrogen, some Helium, and molecular Hydrogen. There are thought to be a mixture of elements in the core.
