The Geosphere

4. – A light-colored, coarse-grained igneous rock rich in quartz and feldspar, main component of continental crust
6. – Places where tectonic plates move apart.
10. – Edges of plates where there is little or no relative movement (also called transform or conservative boundaries in some contexts).
11. – The visible hue of a mineral’s surface.
13. – The formation of Earth’s gaseous envelope from volcanic gases and early chemical reactions.
14. – The Earth's thin, outermost solid layer.
16. – The typical shape or form in which a mineral crystal grows.
18. – Places where tectonic plates move toward each other.

1. – A large slab of Earth’s lithosphere that moves over the asthenosphere.
2. – The thick layer of hot, solid rock beneath Earth's crust.
3. – Quartz, which generates an electric charge under pressure (piezoelectricity).
5. – The Sun and all the planets, moons, and other objects that orbit it.
7. – A dark, fine-grained igneous rock formed from lava, main component of oceanic crust
8. – The idea that the solar system formed from a rotating cloud of gas and dust.
9. – The solid, dense centre of the Earth made mostly of iron and nickel.
12. – The way light reflects from a mineral’s surface (e.g., metallic, glassy).
15. – The property of some minerals to attract iron or be magnetic.
17. – A place where magma rises through the crust away from plate boundaries.
