Their solid, formed in nature, non living and have crystalline structure
What are four characteristic do all minerals share
|
A rock is a naturally occurring solid mixture of one or more minerals or organic matter
What is a rock?
|
The thinnest layer
What are the characteristic of the crust
|
The theory the earths lithosphere is divided into tectonic plates that move on the asthenosphere
What is a tectonic plate
|
They are really hot and rise the cool and fall to the bottom.
More dense-sink Less dense- risp
Convection currents are the process by which rocks constantly rise and fall in the mantle, which in turn moves the tectonics plates. Explain how they are able to move from the top of the mantle to the bottom

Under water volcanoes erupt then cool to creat new ocean crust
Explain the process of sea-flooring spreading at a mid-ocean ridge
|
|
Clastic:Made of fragments of rocks cemented together
Organic: forms from the remains of plant sand animals
What are the key feature of a sedimentary rock?
