Resource summary
C2 A+B
A (STRUCTURE OF EARTH)
OUTER LAYER OF EARTH= LITHOSPHERE
cold,rigid,comprimises crust and top part of mantle
Tectonic plates
Less dense than mantle
Move due to convection currents
Crust to thick to drill
Information of earth collected by seismic waves
OR man made expolsions
Wegener's theory
Africa + south america one land mass
accepted because wide range of evidence + discusses and tested by many scientists
1960's new sea floor spreading evidence
Subduction
Oceanic crust denser than continental crust, they colliide
Oceanic plate sinks,pulling plate down and melting it as it reaches hotter part of mantle
CONSTRUCTION MATERIALS B
RAW MATERILS
EXAMPLES 1,CLAY-BRICK. 2.LIMESTONE+CLAY-CEMENT
HARDNESS MEASURED BY RUBBING 2 MATERILS TOGETHER
FROM EARTHS CRUST
3 TYPES OF ROCK
SEDIMENTARY
Limestone-made from soft sediments compressed/cemented 2gether
Makes limestone soft
METAMORPHIC
Limestone changed by heat/pressure
Composed of an interlocking mosaic of carbonate crystals
IGNEOUS
Granite formed when magma cools/solidifies
Granite is a igneous rock with interlocking crystals, makes it very hard
