Chemical Characteristics
100
List the layers in order of chemical composition, starting at the surface.
What is crust, mantle, core.
100
What is the state of matter of the outer core.
What is liquid.
100
What is the densest layer?
What is the inner core.
200
What layers make up the lithosphere?
What is the crust and uppermost mantle.
200
What is the state of matter of the inner core, and why?
What is solid due to high pressure, even though it is really hot.
200
What happens to pressure, temperature, and density as you move from the surface to the core.
What is they all increase.
300
The crust and mantle are separated, physically, into three layers. Put these three layers in order from the surface of the earth.
What is lithosphere, asthenosphere, mesosphere.
300
Describe the asthenosphere and its importance.
What is it is solid but flowy so it moves around and moves the tectonic plates, causing mountains, earthquakes, and volcanoes.
300
What is the general composition of the core?
What is nickel-iron alloy.
400
What are the two types of crust and which one usually subducts under the other?
What is continental and oceanic. The oceanic crust usually subducts.
400
What is the importance of the outer core.
What is it is liquid nickel and iron and creates the Earth's magnetic field.
400
What is the general composition of the mantle?
What is peridotite.
500
List the layers in order of physical composition from the surface of the earth.
What is crust and uppermost mantle make the lithosphere, asthenosphere, mesosphere, outer core, inner core.
500
Why is the outer core a liquid?
What is it is very hot and there is not enough pressure to make it a solid.
500
What is the general composition of the two types of continental crust.
What is continental - granite and oceanic - basalt.
