b) The liquid outer core is surrounded by a solid inner core.
c) Both the inner core and the outer core are solid.
d) Both the inner core and the outer core are liquid.

Which best explains the movement of tectonic plates?
a) They move several miles each year because of convection within Earth
b) They move several centimeters each year because of convection within Earth.
c) They move several feet each year because of convection within Earth.

a) fine sand only
b) fine sand and silt

a man is using one type of stone to break another. As the stones are broken apart, very tiny pieces are completely pulverized and are swept into the area around the large stone. What can be said about the soil near the large stone?
a) It is different than the stone because the wind blows the pulverized rock far away.
b) It has a chemical composition similar to the stone because of the pulverized rock settling there.
c) Not much will grow there because the stone contaminates the soil.
d) Many animals are attracted to the smell of the minerals and try to create homes in the soil.

Which best summarizes the composition of Earth’s core?
