In our Inquiry topic about Vanishing Earth we have been learning about different types of Rocks and the rock cycle. here is what one group found out.
There are 3 kinds of rocks .
Igneus Rocks: Igneus rocks are formed by fire and the heat when volcanoes errupt and the liquid rock comes up to the earth's surface then becomes solid.
Sedimentary Rocks: Sedimentary rocks are formed when mountains get old and pieces break off and form lots of layers which are pressed together.
Metamophic rocks: Metamophic rocks are made when igneus or sedimentary rocks are changed by heat and pressure.
