100
They are formed from magma
What are magmatic rocks formed from?
100
They are not static, they move and they can change their size and shape

Submerged volcanoes and mountains can be found here
What can be found on an abyssal plain?
200
The continental crust
What creates the continents and the continental shelves?
200
lava from a volcano solidifying quickly on the earths surface
What are volcanic rocks?
200
The internal energy of the earth causes this
What causes convection in the mantle?
200
These are two types of Volcanic eruption
What are explosive eruptions and nonexplosive eruptions?
300
A continental platform ending in a steep slope under the sea
What is a continental shelf?
300
The earths crust forms this.
What is the outer layer of the geosphere?
300
The three main rock types
What are Magmatic, sedimentary and metamorphic?
300
These are the geological processes produced by plate boundary interaction
Volcanoes, earthquakes, mountain ranges and other changes in the earths surface?
300
These are earthquakes
What are movements of land caused by forces from lithospheric plate dynamics?
400
In some places they emerge and create islands
What do some ridges do?
400
the two types of lithosphere
What are the continental lithosphere and the oceanic lithosphere?
400
A method of identifying rock types
What is the arrangement of the crystals?
400
Plate boundary interaction generates this
What generates huge forces, friction and an increase in the temperature of the lithosphere?
400
tectonic forces act on these
What happens to rocks in the lithosphere?
500
These are the 4 spheres or parts on earth
What are the biosphere, atmosphere, hydrosphere and geosphere?
500
These are the three concentric layers of the earth
What are the crust, mantle and core?
500
These are the features of sedimentary rocks
What have spots are fragments compressed by other rocks. There are often fossils between them?
500
The three types of plate boundaries
What are Convergent boundaries, divergent boundaries and transform fault boundaries?
500
These are the 4 parts of a typical volcano
What are the magma chamber, pipe, volcanic cone and crater?
