Name two types of evidence Scientist have that supports the theory of continental drift.
-the continents fit together like a puzzle
-Seafloor spreading
-Fossil evidence
-Glacier evidence
- we have measured movements
600
Name two of the three types of volcanoes
Shield Volcano
Cinder Volcano
Composite volcano
600
What type of waves are these? and how do you know?
S Waves because they cant travel through the liquid outer core
600
Name three of the Earths physical or mechanical layers

600
What word do we use to refer to the thickness of magma? and which type of volcano is more deadly? one with thicker magma or more runny magma?
Viscosity
and Volcanoes with thicker magma are more deadly due to the violent eruptions and molten ash.
