Earth Systems

3. – The solid and liquid parts of Earth, including the core, the mantle, rocks and soil.
4. – The layer of gases surrounding Earth.
5. - evidence of ancient life used to support the theory of plate tectonics
7. - evaporation of water from plants
9. – A scientist who proposed the theory of continental drift, suggesting that continents once formed a single landmass and have since moved apart.
11. – The regions of Earth that support life.
14. – Earth’s thin, outermost layer where we live. It is made of solid rock and divided into continental and oceanic.
16. - magnetic element that makes up Earth's core
19. – Process where plants use sunlight to make food, created Earth's oxygen
21. - _________ from the core and mantle drives the movement of the tectonoic plates
22. – The center of Earth, made of two parts: a solid inner core (iron and nickel) and a liquid outer core that generates Earth’s magnetic field.
23. – Rain, snow, hail, or sleet falling from clouds.

1. – The cycle that is partially driven by the movement of tectonic plates.
2. – The process of water vapour turning into liquid.
6. – A supercontinent that existed about 300 million years ago, when all of Earth’s continents were joined together before breaking apart.
8. – The thick, middle layer of Earth between the crust and the core. It is mostly solid rock but can flow slowly over time.
10. – The rigid outer layer of Earth, made up of the crust and the uppermost part of the mantle.
12. - bacteria; Earth’s first life
13. – The process of liquid water turning into vapour.
15. – Water that flows over the land surface into rivers and lakes.
17. – A soft, semi-fluid layer of the mantle beneath the lithosphere that allows tectonic plates to move.
18. – A large, rigid section of Earth’s crust that moves.
20. – All the water on Earth’s surface and underground.
