 Objective: you will learn about Earth’s inner
structures; Earths’ crust, mantle, and core.
 Starter: What do you know about the Earth’s Inner
core?
Know
It is hot
Made of Iron
Different temperatures
Many different layers
What I want to Know
How hot is it in the center
of the core ?
How big is it?
How fast things go?
What I learned
 Objective: you will learn about Earth’s inner
structures; Earths’ crust, mantle, and core.
 Starter: What do you know about the Earth’s Inner
core? (1 paragraph)
 They are produced after an earthquake; scientists
study them to see how they traveled through earth.
 The layer of rock
that forms Earth’s
outer skin.
A layer of hot and solid
rock; 40 kilometers
below the Earths
surface.
 The Uppermost part of
the mantle and the crust.
A part of the mantle just below the
lithosphere. A some what soft layer
that can bend.
 A layer on molten metal
that surrounds the inner
core.
A dense ball of solid
metal.
 Have you ever dug a hole in the ground? If you dig
down deep enough what do you hit? What else do you
think is below the rock?

and how heat is transferred.
 Starter: What are seismic waves? How are they related
to earthquakes?

 In a room at your home, why is it colder near the floor
than near the ceiling?
 The transfer of energy through space.
 Heat transfer within a material or between materials
that are touching.
 Heat transfer by the movement of currents within a
fluid.
 A measure of how much mass there is in a volume of a
substance
 The flow of transfer of heat within a fluid.

 Objective: You will learn about the Pangaea theory.
 Starter: What do you know about the continents?
 What is a continent? Can you name them? Have they
always been in the same place?
 A theory that continents slowly moved apart over
Earths surface.
 Alfred Wegener proposed that all continents were
joined together at one point in history.
 Any trace of an ancient organism that has been
preserved in rock or tree sap.

 Objective: You will learn about sea floor spreading.
 Starter: How do continents move? What is theory that
the continents were once formed as one?
 Where does magma from Earth’s interior flow out onto
the surface? What happens with the lava after it goes
onto the surface?
 An undersea mountain range.
 A device that bounces sound waves off underwater
objects and then records the echoes of these sound
waves.
 The sea floor spreads apart along both sides of a mid
ocean ridge and new crust is added.
 Deep underwater canyons
 The process by which the ocean floor sinks beneath a
deep ocean trench and back into the mantle.

 Cracks in the continent that fit along a crack in the
lithosphere.
 A theory that pieces of Earth’s lithosphere are in slow,
constant motion, driven by convection currents in the
mantle.
 Breaks in Earth's crust where rocks have slipped past
each other.
 The place where two plates move apart.
 A deep valley that forms after spreading boundaries
develops on land.
 The place where two plates come together or collide.

 A place where two plates slip past each other, moving
in opposite directions.
