Question :)
What is the outer layer of Earth called?
The crust
What is it called when one plate slips past another?
A transform boundary.
What is the theory that explains moving plates called?
Plate tectonics.
What causes the seafloor to spread?
New crust forms
What happens at a subduction zone
One plate sinks under another.
What are Earth’s tectonic plates?
Large pieces of Earth’s crust and upper mantle.
What happens at many plate boundaries?
Earthquakes and volcanoes can happen there.
Which layer of Earth is made of moving plates?
The lithosphere.
What is a fault?
A crack in Earth’s crust
What plate boundary usually creates mountains?
A convergent boundary
Are tectonic plates always moving or do they stay still
moving very slowly
What do earthquakes happen from?
The sudden movement of Earth’s plates or faults.
What landform can form when plates push together
Mountains.
Where do most earthquakes happen
Near plate boundaries.
What plate boundary often creates mid-ocean ridges?
A divergent boundary.
What is it called when two plates move apart?
A divergent boundary.
What can form when molten rock reaches the surface?
A volcano.
What ocean feature can form when plates move apart?
A mid-ocean ridge
What is one effect of plate movement on Earth’s surface?
It can change landforms.
What is one example of evidence that plates move?
Matching fossils or matching coastlines.
What is it called when two plates crash into each other
A convergent boundary
What is magma called once it comes out of a volcano?
Lava
Why do continents look like puzzle pieces in some places?
joined together
How do volcanoes and plate tectonics connect
Volcanoes often form where plates meet or separate.
Why is plate tectonics important to Earth science
It helps explain earthquakes, volcanoes, mountains, and continents.
