Setting Boundaries
When two tectonic plates collide.
Convergent plate boundary
Where can you find igneous rocks?
Near volcanoes. They are made from cooling magma or lava.
What layer of the Earth is made of liquid magma?
Mantle
A big wave
Tsunami
How many stars are in our solar system?
1 star. It's the Sun.
When two tectonic plates slide past each other. Earthquakes commonly occur here.
Transform plate boundary
Sedimentary rocks are made from...
Tiny rocks OR sediment that are broken from larger rocks through weathering.
In this layer, convection currents occur, causing the crust to move.
Mantle
Describe one technology that can warn people of a natural disaster.
Phone alerts, sirens, TV announcements, the news etc.
What year did Martin Luther King Jr. give the "I have a dream" speech?

How do you turn an igneous or sedimentary rock into a metamorphic rock.

This layer floats on top of the mantle.
Crust
A tsunami siren goes off. You have 20 minutes to respond. What should you do?
Move to higher ground, warn others etc.
How many legs do lobsters have?
10 legs
Tsunamis can be caused by these two plate boundaries.
Convergent (volcanoes) and Transform (earthquakes)
How do you turn a sedimentary or metamorphic rock into an igneous rock?
Melt the rocks and then let the magma or lava cool.
Layers are a common feature of this type of rock.
Sedimentary rock
Stronger buildings, anchor furniture to the floor, stronger windows etc.
How many kids does Mr. Chieffo have?
2 kids
What plate boundary is responsible for creating oceans (for example, South America and Africa were once connected but are now separated by the Atlantic Ocean).
Divergent plate boundary (A rift valley formed and moved the continents AWAY from each other)
Name both plate boundaries where you could find an igneous rock.
Divergent boundary (mid-ocean ridges) and Convergent boundary (volcanoes)
Broken up pieces of crust.
Plates
Describe one technology that can detect a tsunami.
Measuring sea level, animal behavior, causes of tsunamis (earthquake/volcanic activity) etc.
How many students are there in the 7th grade?
