Earth Science vocabulary matching worksheet with definitions and answer choices.

Let's solve this Earth Science matching exercise step by step. We have 20 definitions on the left and a list of possible answers (A–T) on the right. Our goal is to match each definition with the correct term.

Step-by-step Matching:

1. a zone where Earth's crust and mantle are being pulled apart
→ This describes a rift (like the Mid-Atlantic Ridge).
✔ Q. rift

2. a depression in the ocean floor
→ A deep area in the ocean floor is called a trench.
✔ N. trench

3. molten rock below Earth's surface
→ Molten rock beneath the surface is magma.
✔ K. magma

4. the crust that has formed the continents
→ This is continental crust.
✔ O. continental crust

5. a place where extremely hot materials from inside Earth's erupts at the surface
→ This is a volcano.
✔ L. volcano

6. isolated place away from the plate boundaries where a lot of hot magma is collecting
→ This refers to a hot spot, like Hawaii.
✔ B. hot spot

7. when one plate sinks below another plate during collision
→ This process is called subduction.
✔ H. subduction

8. a huge wave in the ocean caused by an earthquake occurring on the sea floor
→ This is a tsunami.
✔ A. tsunami

9. a deep channel in the ocean floor where crust is sinking downwards
→ This is a trench (same as #2, but more specific).
✔ N. trench

10. name for the crust and the upper mantle together; Earth's tectonic plates
→ The lithosphere includes the crust and uppermost mantle.
✔ F. lithosphere

11. Earth's outermost solid layer
→ This is the crust.
✔ T. crust

12. plates are pulled apart at the mid-ocean ridges
→ This is due to slab pull or ridge push, but "slab pull" is the force pulling plates apart at ridges.
Wait — actually, slab pull is when a subducting plate pulls the rest of the plate down. But the spreading at mid-ocean ridges is due to upwelling mantle and ridge push — not slab pull.
But the question says: "plates are pulled apart at the mid-ocean ridges" — that’s not quite accurate. Plates are pushed apart at ridges due to upwelling mantle.

But looking at the options, E. slab pull is listed. However, slab pull is a force that pulls plates toward subduction zones, not directly responsible for spreading at ridges.

Wait — perhaps there's confusion here.

Actually, slab pull is a major driving force of plate tectonics, and it helps pull plates apart at ridges. So indirectly, it contributes.

But the best answer for “plates are pulled apart at mid-ocean ridges” might be E. slab pull, since it's a key mechanism.

Alternatively, D. fold mountain? No — that’s unrelated.

Wait — let’s look again.

Actually, mid-ocean ridges are associated with divergent boundaries, where plates are pulled apart due to mantle convection and ridge push, but slab pull is a force that pulls plates *away* from ridges.

So slab pull does help pull plates apart at ridges.

Yes — so E. slab pull is the correct choice here.
✔ E. slab pull

13. the shackling, wave-like movement of ground in an earthquake
→ This is seismic wave.
✔ J. seismic wave

14. section of Earth's crust that moves about on Earth's surface
→ This is a tectonic plate.
✔ C. tectonic plates

15. the place below ground where an earthquake starts
→ This is the focus (also called hypocenter).
✔ I. focus

16. plate boundary where lithosphere is destroyed
→ This happens at convergent boundaries, especially where subduction occurs → destructive boundary.
✔ S. destructive boundary

17. a layer of 'plastic' semi-solid rock in the lower mantle on which Earth's tectonic plates move
→ This is the asthenosphere.
✔ G. asthenosphere

18. mountains form by crust crumpling upwards as plates collide
→ This forms fold mountains.
✔ D. fold mountain

19. a chain of islands formed at the edge of colliding tectonic plates where one plate subducts
→ This is an island arc, like the Japanese Islands.
✔ R. island arc

20. an instrument that detects the seismic waves from an earthquake
→ This is a seismometer.
✔ M. seismometer
