This essential requirement for life helps regulate temperature and allows chemical reactions to occur.
Liquid water
100
This type of evidence shows continents were once connected.
Fossils
100
This boundary forms new ocean crust.
Divergent boundary
100
Fertilizer runoff can cause this harmful event in lakes and rivers.
Algal bloom
100
What is overfishing?
Catching fish faster than they can reproduce
100
This organism type forms the base of every energy pyramid.
Producers

This type of plate boundary is shown in the diagram.
Divergent boundary
200
Earth’s atmosphere protects life primarily by doing these two things.
Blocking harmful radiation & trapping heat
200
Rock layers found in different continents match in age and composition. What does this suggest?
Continents were once joined
200
Earthquakes are most common at these locations.
Plate boundaries
200
When algae overgrow and oxygen levels drop, this forms.
Dead zone
200
Burning fossil fuels contributes to this ocean problem.
Ocean acidification
200
Only about this percentage of energy transfers to the next trophic level.
10%
200
This geological feature forms above the subducting plate.
Volcano (volcanic arc)
300
If Earth had no magnetic field, what major threat would increase for living organisms?
Solar radiation exposure
300
What evidence supports continental drift?
Fossil, geological, and climatic evidence
300
When one tectonic plate sinks beneath another, this process occurs.
Subduction
300
Paved surfaces increase this process, leading to more flooding.
Runoff
300
When algae overgrow and use up oxygen in the water, what forms that kills fish and marine life?
Dead zone
300
Why are there fewer organisms at the top of an energy pyramid?
Less energy available
300
Why are volcanoes uncommon in this type of collision?
Neither plate subducts deeply enough to melt and form magma
400
Why is Earth’s distance from the Sun critical for sustaining life?
It allows temperatures that support liquid water
400
What is the rigid outer layer of Earth that is divided into tectonic plates?
Lithosphere
400
A mountain range formed without volcanic activity likely formed from what type of boundary?
Convergent (continental-continental)
400
Why does removing vegetation increase erosion in a watershed?
Roots no longer hold soil in place
400
What happens to marine animals when they mistake plastic for food?
They can choke, starve, or die
400
If a top predator is removed, what likely happens to primary consumers?
Population increases
400
Which labeled zone most likely represents the Goldilocks Zone, and why?
Zone B — it allows liquid water to exist
500
A planet has water but no atmosphere. Explain why life would struggle to survive there.
No protection from radiation & no temperature regulation
500
What is the name of the hot, slowly flowing layer beneath the lithosphere?
Asthenosphere
500
Explain why volcanic activity is common along the Pacific Ring of Fire.
Many convergent/subduction boundaries
500
Explain how pollution upstream can affect communities downstream.
Water flows through the watershed carrying pollutants
500
Explain how rising ocean temperatures impact coral reefs.
Coral bleaching due to stress
500
Explain why energy pyramids are always upright and never inverted.
Energy decreases at each level
500
The diagram shows two plates moving side-by-side in opposite directions.
What type of plate boundary is shown, and what major geological event is most likely to occur here?
Transform boundary; earthquakes
