What’s the origin of a meteor shower?

I hope this helps I read this in a book once

Explanation:

Shower meteors come from the dust released by comets as they travel through our solar system. The dust spreads out along the comet's orbit and forms an elliptical trail of debris that passes around the sun and crosses the orbits of the planets.

The answers are B. Basalt and D. Granite.

Explanation:

Basalt is an extrusive igneous rock, solid and It is formed by abundant dark minerals such as pyroxene and olivine, which make basalt gray or dark black. It is the most common type of rock in the earth's crust, and covers most of the ocean floor.

Granite is a volcanic plutonic rock formed by the slow cooling of magma to great depths of the earth's crust. This cooling allows large crystals to form, resulting in a crystalline texture, characteristic of granites.
