Terrific El Torcal

Our Science Topic this term is Rocks.  Did you know that wherever we are in the world, there is always rock underneath us?

We have learnt that rocks fall into three types – sedimentary, metamorphic and ignaeous.

Sedimentary rocks are formed when sediments (sand, mud, small rocks) settle in layers.  Over time, the layers are squashed together under more and more layers, which eventually become rock. An example of a sedimentary rock is limestone which we have a lot of in the south of Spain.

Metamorphic rocks are rocks which have been changed into a different type of rock by heating up or squashing the earth’s crust.  Marble, which we use a lot in buildings in Spain,  is just one example.

The word Ignaeous comes from the Latin word ignis, which means fire.  Ignaeous rocks are formed when magma or lava cools and solidifies.  They often sparkle.  Granite is one example. 

As part of our learning, we went on a trip to El Torcal de Antequera, a beautiful mountainous area, a two hour journey from our school.  Click on the link below for some pictures of our day.
