Answer to Question 1

Internal processes derive energy from Earth's interior (such as tectonic activity). External processes derive energy from the Sun and occur at or near Earth's surface (such as mass wasting).

Answer to Question 2

Both schist and gneiss have foliated textures, whereas both quartzite and marble are nonfoliated.
