core

The Earth magnetic field originates in the

• mantle

• crust

• inner core

• outer core

The mantle takes up the greatest

• space

• volume

• temperature

• pressure

The mantle consist mainly of

• iron and nickle

• iron and magnesium

• iron and calcium

• iron and basalt

The semi liquid layer situated in the upper mantle is called

• lithosphere

• mesosphere

• asthenosphere

• atmosphere

The inner core is

• solid

• liquid

• semi molten

• partially molten

The continental crust is composed mainly of

• light coloured granitic rocks

• dense colouredgranitic rocks

• light coloured basaltic rocks

• dense coloured basaltic rocks

The theory suggested that earth was a super continent called

• Panthalassa

• Laurasia

• Pangaea

• Gondwanaland

One evidence given to support the theory of continental drift is

• coal strata in the arctic

• Ice age in the Antarctic

• matching fossil reptiles in Africa and South America

• common plants found in America

The oceanic plate found adjacent to the Caribbean is called the
