Earth's Layers & Structure
What layer is made up of the crust and uppermost mantle and behaves like a solid?
Lithosphere
What do we call the places where the edges of two plates meet?
Plate Boundaries
What process involves one plate sinking beneath another?
Subduction
Double Jeopardy! What is gradual movement of the continents slowly over Earth’s surface? The theory of continental drift teaches that Earth’s continents have slowly moved over time. How can this remind us that while the Earth changes, God never changes?
1-Continental Drift
2- Though continents shift and landforms change, God’s character and promises remain constant.
What type of mountain forms when rock layers are pulled apart and large blocks slide downwards?
Fault-Block Mountain
What layer lies just below the lithosphere and behaves plastically because it is so hot?
Asthenosphere
At what type of plate boundary do plates move apart?
Divergent Boundary
What happens on the ocean floor when subduction occurs?
A trench forms
Name the three types of plate boundaries?
Divergent, convergent, transform
Double Jeopardy! What type forms when rock layers are folded as plates collide? Folded mountains form when plates collide and rocks bend under pressure. How God can use challenges (or pressure) in our lives to strengthen us?
1-Folded Mountain 2- Just as pressure forms mountains, God can use difficulties to build trust in Him and endurance, character, and hope in us.
What causes the lithospheric plates to move slowly over the asthenosphere?
Convection Currents
What type of boundary occurs when two plates collide?
Convergent Boundary
Double Jeopardy! What is responsible for the movement of Earth’s plates? When we learn about convection currents and plate boundaries causing mountains and volcanoes, how can this remind us of God’s power described in Psalm 104:32, which says, “He looks at the earth, and it trembles”?
1-Convection Currents 2- The forces moving Earth’s plates show God’s mighty control over nature, even through natural processes like earthquakes and volcanoes
What forms when and Oceanic plate subducts below a Continental plate?
Volcano
What type of mountain forms when forces inside Earth push the crust upward?
Upwarped Mountain
The Earth’s plates are found in which layer?
Lithosphere
What type of boundary occurs when 2 plates slide past one another?
Transform Boundary
When two oceanic plates collide, which one subducts?
The older, denser plate
What forms when an oceanic plate subducts beneath another oceanic plate?
Island
What type of mountain forms from lava piling up on Earth’s surface?
Volcanic Mountain
True or False: The asthenosphere is completely liquid.
False – it is solid but flows like a thick liquid
What happens when one plate is forced below another?
Subduction
Only which type of plate can undergo subduction?
Oceanic plates
What was the name of the hypothetical giant landmass that existed when all continents were joined?
Pangea
What is the name of a famous Folded Mountain you studied in Science?
Himalayas
