This is the thinnest layer of the planet.
Lithosphere
This is the thickest layer of the planet .
Mantle
This layer of the planet is a liquid
Outer core
What two conditions increase as we go deeper into the earth?
Temprature and pressure
What is the inner core and outer core made from?
Nickel and iron.
This force is responsible for moving the continents.
Convection currents
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.
Which rock type is produced by magma cooling on the surface.
Metamorphic
Igeous
None of above
Sedimentary
Which rock type is made from lots of smaller rocks and minerals?
Metamorphic
Igneous
Sedimentary
Mineral
What rock type is produced by exposing other rocks to heat and pressure?
Sedimentary
Igneous
Basalt
Metamorphic
Which of the following is not a type of plate boundary?
Transform
Divergent
Volcanic
Convergent
Sediments are produced by what process?
Mineralization
Erosion
Sedimentation
Weathering
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
Give three examples of weathering.
Ice-wedging, exfoliation, root-wedging, oxidation, hydrolysis etc....
Which plate boundary/ies produce volcanoes?
Convergent and divergent
