Fossils
Paleontologists are people who study fossils from earlier geologic times. They excavate the land surrounding the fossil.
In class we did a lab with our partners. We had to excavate plaster that had fossils inside, just like paleontologists do. Were we given tools to be able to excavate.
After, we had gotten all four of the fossils we had to identify the fossil and the age period is was found in and we put it in layers called strata.

Volcanoes
Composite volcano
a tall cone shaped mountain in which layers of lava alternate with layers of ash and other volcanic materials (stratovolcano)
Cinder Cone volcanoes
a steep, cone-shaped hill or small mountain made up of volcanic ash, and bombs piled up around a volcano's opening.
Shield Volcano
when fluid lava is extruded, the volcano takes the shape of the non-steep broad, domed structure, built primarily of fluid basaltic lava, can be some of largest volcanoes.
Tectonic Plate movement
Divergent Boundary
this has tensional stress, this type of stress happens when two plates are pulling apart from each other
-
Convergent Boundary
has compressional stress, this stress happens when two plates are pushed together
Transform boundary
has shear stress, this type of stress happens when two plates are sliding one another
