Rocks, Rocks, and More ROCKS!
By ZACH BURKE
The Plates HAVE MOVED!!
Plates are the broken parts of the lithosphere. Plates are located all around the earth. These plates move because the lithosphere is in constant slow motion. There are converging plates, diverging plates, and transform boundries.
Earthquakes
Earthquakes destroy the land around the faults.
Volcanoes
Volcanoes add to the land and destroy all the plant life around it. They also make islands.
Sea Floor Spreading
Sea floor spreading is making the sea bigger and the continents farther and farther apart. This makes the world a whole different place.

Yeah i'm Zachary ... I dont like school.
Fossils
Law of Superposition
This states that the oldest rock is at the bottom and the youngest rock is on top.
How can fossils tell us about the history of the earth
Fossils can tell us what animals roamed the earth millions of years ago.
Are all fossils the same
No some fossils look different than others.
Rocks and minerals
Sedimentary Rocks
This forms when sediments pile up and with time and pressure it turns into this rock.
Metamorphic Rock
These form when rock has extreme heat and pressure it turns into this rock.
Igneous Rock
This forms when magma/lava cools.
The rock cycle is a type of cycle that explains how one type of rock turns into another type of rock. For example a sedimentary rock turned into a metamorphic rock. First the sedimentary rock could go by magma. Then with heat and pressure this sedimentary rock would turn into a metamorphic rock.
Minerals can form from magma/lava and they can also form from Solutions. We can identify minerals by their hardness, luster, crystal composition and more!
I like how we learned about volcanoes and how they go BOOM!
