Dynamic Earth

5. I travel through the Earth with speed, from quakes and eruptions, I proceed. What am I?
6. Solid and dense, I sit at the centre, made of iron and nickel, I am the Earth's mentor. What am I?
7. Between the crust and core, I lie, with silicate rocks, I occupy. What am I?
9. Deep within the Earth, I begin, the starting point of the seismic din. What am I?
11. I rise high into the sky, a grey plume from a volcanic sigh. What am I?
15. When I occur, the Earth does shake, releasing magma, ash, and quake. What am I?
17. Beneath the surface, I quietly reside, molten and hot, in the Earth's side. What am I?
18. I record the Earth's tremors and shakes, capturing data for science's sake. What am I?
19. Tall and layered, I stand with pride, my eruptions can be fierce and wide. What am I?
20. I travel along the Earth's face, causing the most noticeable quake. What am I?
22. I am where plates move apart, creating new crust, a geological art. What am I?
23. I explain the Earth's shifting ground, with plates that move all around. What am I?
25. An ancient land, now split and gone, I once held continents in my throng. What am I?
26. I am where plates collide and meet, often causing one to retreat. What am I?

1. Liquid and flowing, I surround the heart, in the Earth's core, I play my part. What am I?
2. I am broad and wide, with gentle slopes, my lava flows with ease. What am I?
3. I am a wave that rises high, caused by quakes beneath the sky. What am I?
4. I am where plates slide side by side, causing friction as they glide. What am I?
8. Directly above the quake's true start, I mark the spot on the Earth's chart. What am I?
10. I measure the quake's might, on a logarithmic scale, I take flight. What am I?
12. Small and steep, I rise from the ground, built from ash and debris all around. What am I?
13. I am the Earth's outer shell, rigid and strong, where tectonic plates dwell. What am I?
14. A thermal plume beneath the crust, creating islands, as I must. What am I?
16. A supercontinent of the past, where all Earth's lands were amassed. What am I?
18. I follow behind, moving side to side, slower than my counterpart, I glide. What am I?
21. I am the Earth's outermost layer, where land and sea meet in nature's fair. What am I?
24. Once I break free, I flow and I glow, from the Earth's surface, I put on a show. What am I?
27. I am the fastest, moving through the ground, compressing and expanding all around. What am I?
