Tectonic Plates Flashcards
Layers of the earth
Inner core- hottest section of the earth and the centre
Outer core- layer surrounding the inner core
Mantle- made of semi molten rock called magma, thickest section
Crust- outer layer where people live on
Plate boundaries
➡️⬅️ colisión

Composite volcano
destructive plate boundaries.
Violent eruptions volcanic bombs
Lava thick like treacle
Number of vents abs parasitic cones
Lava moves slowly
Narrow base due to slow moving lava
Shield volcano
Made of lava
Thin runny lava which moves quickly
Runs down hill quickly
Spreads over long distance
One large vent
Continental drift
the tectonic plates don’t just stay in one position and that they actually move around
Seismometer
measures earthquakes
Earthquake and volcanos found
They are found near plate boundaries
