Title: Living Things


1
Earths Structure and Materials
Table of Contents Earths Interior Convection and
the Mantle Classifying Rocks Igneous and
Metamorphic Rock Sedimentary Rocks The Rock Cycle
2
Earths Interior
Waves Paths of ocean waves change when the waves
reach an island.
3
Earths Interior
Earths Crust The circle graph shows the
composition of Earths crust.
4
Earths Interior
Mantle Piece Earths mantle is nearly 3,000
kilometers thick. The rigid lithosphere rests on
the softer material of the asthenosphere.
5
Order of Earths Layers
  • Crust
  • Mantle (lithosphere which includes crust and
    asthenosphere)
  • Outer Core
  • Inner Core

6
Earths Interior
Temperature Inside Earth The graph shows how
temperatures change between Earths surface and
the core. Can you read this graph?
7
Convection and the Mantle
How does a Lava Lamp Model Convection Currents?
Mantle Convection Heat from the core and the
mantle itself causes convection currents in the
mantle.
8
Classifying Rocks
Rock Origins Rocks are classified by the way they
formed.
9
Sedimentary Rocks
How Sedimentary Rock Forms Sedimentary rocks form
through a series of processes over millions of
years.
10
Sedimentary Rocks
What is the proper sequence of the terms in the
word bank that will show how mountains can change
into sedimentary rock?
11
The Rock Cycle
The Rock Cycle Through melting, weathering and
erosion, and heat and pressure, the rock cycle
constantly changes rocks from one type into
another type.
12
The Rock Cycle
Patterns in the Rock Cycle Surface Events All of
the paths of the rock cycle result from only a
few surface and subsurface processes. What words
belong in the empty boxes in the graphic
organizer?
