What process causes the formation of sedimentary rock
Lithification of sedimentary particles
Which crust is the densest?
Oceanic crust
Seismic activity in the crust is also known as
an Earthquake
The lithification of what created sedimentary coal around the world?

What is a difference between magma and lava?
Lava is on the outside (extrusive); magma is on the inside (intrusive)
What factors cause one rock to transform into metamorphic rock?
Heat and pressure
When oceanic and continental crust converge what are the geological consequences?
Tallest mountains in the world are a) called and b) caused by?
Himalayas and converging continental plates
What are tailings?
Waste products from the process of refining mineral ores.
Why is the outer core responsible for the Earth's magnetic field?
Because it is liquid - moving charge creates magnetic field
Weathering and erosion.
When two oceanic plates diverge what occurs?
Rift valley, fissure volcanoes, new crust formation
What occurs at a transform boundary? Give a real life example

What process occurs in the mantle?
Convection currents
What factors effect the formation of crystal size in igneous rock?
Temperature and time. High temperature and long time lead to large crystals.
How do we know that the Earth is made up of tectonic plates? What evidence is there?
