NOTES

2. Tectonic plates pulling apart which can create rift valleys on other planets
4. The process where an unstable atomic nucleus loses energy and matter by emitting radiation
8. Earth's outer layer is divided into large, moving slabs of rock.
10. Energy waves generated by the sudden release of energy within a planetary body.
11. A seismic wave that travels through the Earth's interior by compressing and expanding the ground.
12. A shape that is flattened at the poles and bulges at the equator, like a sphere that has been squashed.
13. A layer of rock or ice between a planet's core and its crust.
15. The transfer of heat in fluids.
16. The process of plants creating glucose and oxygen.

1. A natural light display in Earth's atmosphere.
3. Seismic waves that cause the ground to shake side to side.
5. A layer of gases that surrounds a celestial body
6. The apparent deflection of moving objects like winds, ocean currents, and even large storms, caused by the rotation of a planet.
7. A super continent that existed 300-200 million years ago
9. A natural process where certain gases in the Earth's atmosphere trap heat from the sun, which warms the planet.
10. The geological process where one tectonic plate slides or dives beneath another plate at a convergent boundary.
14. The mass per unit volume of an object or region, calculated by dividing total mass by total volume.
