Students complete nine fill-in-the-blank problems about tectonic plates, mantle convection currents, and plate boundaries. The matching activity pairs mantle convection, outer core movement, plate boundaries, and crust plates with their Earth-system roles.
Connecting Earth's internal layers to surface events — earthquakes, volcanoes, and plate motion — reveals the Earth layers topic as part of an interconnected system rather than isolated facts about depth and temperature.
Style:
Earth's Layers
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Earth's crust is divided into large pieces called tectonic plates.
2. Convection currents in the mantle cause tectonic plates to move slowly over time.
3. Volcanoes and earthquakes happen most often at plate boundaries.
4. The movement of liquid iron in the outer core creates Earth's magnetic field.
5. Earth's magnetic field protects living things from harmful solar radiation.
6. When tectonic plates push together, they can form mountain ranges over millions of years.
7. Hot melted rock that rises from the mantle to the surface is called magma.
8. An earthquake occurs when tectonic plates suddenly shift and release energy.
9. The Ring of Fire is an area around the Pacific Ocean with many volcanoes and earthquakes.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Mantle convection currents
→ Drive tectonic plates to move across Earth's surface
Where most volcanoes and earthquakes occur
Outer core movement
→ Creates Earth's magnetic field that shields us from solar wind
Drive tectonic plates to move across Earth's surface
Plate boundaries
→ Where most volcanoes and earthquakes occur
Large puzzle-like pieces that make up Earth's outer shell
Crust plates
→ Large puzzle-like pieces that make up Earth's outer shell
Creates Earth's magnetic field that shields us from solar wind
