Tectonic Plates Flashcards
Later of the earth made of solid metals
Inner core
Layer of the earth with most dense metals
Inner core
Layer of the earth made of liquid metals
Outer core
Layer of the earth with toothpaste, tar-like rock right below the crust
Asthenosphere
The rising and falling of rock In a circular motion due to temperature changes
Convection current
Layer of the earth where convection currents move the lithosphere
Asthenosphere
Layer of the earth made of part crust, part mantle
Lithosphere
The different pieces of the crust that are like broken egg shell
Tectonic plates
Where do volcanoes and earthquakes tend to occur
Along the edge of tectonic plates
A valley created by subducting plates
Rift Valley/ trench
2 plates coming or crashing together
Converging
2 plates moving away from each other
Diverging
2 plates moving sideways to each other
Transform
A spot on earths mantle where a lot of magma seeps through the crud to make a chain of islands
Hot spot
Who’s more dense- ocean crust or continental crust?
Ocean
