The layer of rock between the lithosphere and mantle. Here the temprature is higher and the rock is softer and more flexible.
This is the thickest layer of the planet .
Mantle
True or false? The inner and outer core are made from the same elements?
True
True or false? Less dense material is found deeper in the planet interior.
False
Explain what are convection currents regarding plate tectonics.
Surface rock is cooler and more dense. This means it will sink into the less dense mantle. Mantle material is hotter and less dense where it will rise.
In which nutrient cycle does plate tectonic movement play an essential role.
Phosphorus
Which rock type is produced by magma cooling on the surface.
Sedimentary
Metamorphic
Igeous
None of above
This layer of the planet is the most dense.
Inner core
Which plate boundary/ies produce volcanoes?
Convergent and divergent
Describe what is a sedimentary rock.
A rock that is made from sediment. Layers of sediment pile up on each other and become compacted into rock.
