LEARNING OBJECTIVES UNDERSTAND THE STRUCTURE OF THE EARTH IDENTIFY THE DIFFERENT LAYERS OF THE EARTH

TECTONICS?

THE EARTHS STRUCTURE -STARTER CAN YOU THINK WHAT THIS IMAGE HAS TO DO WITH THE EARTHS STRUCTURE? YOU HAVE ONE MINUTE TO SEE IF YOU CAN COME UP WITH AN ANSWER

THE EARTHS STRUCTURE ALTHOUGH IT MAY SOUND STRANGE A GOOD WAY AT UNDERSTANDING THE STRUCTURE OF THE EARTH IS TO THINK OF IT AS AN EGG. THE THIN SHELL IS THE ‘CRUST’ THE WHITE SOFT PART IS THE ‘MANTLE’. THE YELLOW YOLK IS KNOWN AS THE ‘CORE’

THE EARTHS STRUCTURE CAN YOU IDENTIFY THE CORRECT LAYERS USE YOUR WORKSHEET PROVIDED TO CORRECTLY LABEL THE DIFFERENT LAYERS Crust Mantle Outer Core Inner Core

THE EARTHS STRUCTURE WHAT DO YOU THINK THE CORE IS MADE OF? The core is mainly made of iron WHAT TEMPERATURE DO YOU THINK THE MANTLE IS? The mantle is approximatley 1000C, relatively cool compared to that of the core WHAT DO YOU THINK HAPPENS WITH PRESSURE THE FURTHER YOU GO DOWN THROUGH THE EARTHS STRUCTURE

THE EARTHS STRUCTURE WHAT DO YOU THINK THE MANTLE IS MADE OF? HOW DO YOU THINK PLATES MANAGE TO ‘ FLOAT ’ ON THE MANTLE? The mantle is made of a number of materials such as iron, magnesium, aluminium and oxygen. WHAT SORT OF TEMPERATURE DO YOU THINK THE CORE IS? The core is approximatley 4300 C the outer core is less hot at about 3700 C

THE EARTHS STRUCTURE How thick do you think the crust is? Roughly between 5-30km thick How thick do you think the mantle is? Approximatley 2900km How thick do you think the core is? The liquid outer core is roughly 2200km and the solid inner core is 1250km thick From the information you have just gained go back to your diagram and add the relevant information to it eg temperature/thickness etc.

TYPE THICKNESS TEMPERATURE MATERIAL CRUST MANTLE INNER CORE OUTER CORE 5 – 30 km 2900 km 2200 km 1250 km Rock minerals Iron, magnesium and aluminium Solid iron Molten iron N/A 4300 C 3700 C 1000 C

TECTONIC PLATES WHAT DO YOU NOTICE ABOUT THE NAME OF THE PLATES AND THEIR LOCATIONS? WHAT DO YOU THINK THE ARROWS REPRESENT?

TRUE OR FALSE? THE HOTTEST PART OF THE EARTH IS THE MANTLE TECTONIC PLATES ARE OFTEN NAMED AFTER THE CONTINENT THEY SIT ON THE INNER CORE IS MADE OF SOLID IRON PLATES MOVE IN THE SAME DIRECTION THE MANTLE IS ROUGHLY BETWEEN 5- 30km thick
