Layers of the Earth
What are the three composition layers of the Earth?
Crust, Mantle and Core
What super-continent was formed according to the Continental Drift Theory?
Pangea
What layer is what makes up the Earth's plates?
The lithosphere
What type of plate boundary causes earthquakes?
transform faults
What structure on a volcano is where the volcanic material eject out of?
The vent
What is the core made out of?
Iron and Nickel
What piece of evidence in Continental Drift theory state that the continents' coasts look like they fit together?
The Continental Puzzle
What type of plate boundary moves apart?
divergent boundaries
What is the spot on the Earth's crust that is directly above where the earthquake originated below the surface?
the epicenter
What type of volcano is created from an accumulation of lava on the ocean floor?
Shield volcanoes
What are the physical property layers of the Earth?
Lithosphere, Asthenosphere, Inner Core, Outer Core
What type of evidence showed that ancient organisms were found on different continents meaning they must have been connected at one point in time?
Matching fossils
What type of plate boundary moves towards each other?
convergent boundaries
What are the two movements that can occur before and after and earthquake?
Foreshocks and Aftershocks
What type of volcano is almost symmetrical and is the most common type in the ring of fire?
composite cone
What makes up the lithosphere?
What piece of evidence states that mountain ranges with the same age and types of rocks are found on different continents?
Rock Types and Structures
What type of plate boundary slides past each other?
Transform faults
What natural disaster can be caused by seismic vibrations?
Tsunamis
What type of volcano is created by loose pyroclastic materials?
cinder cones
What makes up the asthenosphere?
The upper mantle.
What is the current theory on how the continents move?
Plate Tectonics Theory
What is the difference between Continental Drift theory and Plate Tectonics theory?
CDT= continents move/float over sea floor
PTT= continents move with the sea floor
The damage to buildings and other structures from earthquake waves depends on?
(give me two factors out of four)
Intensity
Duration
Foundation of structure
design of the structure
What type of plate activity creates volcanoes within a plate due to magma rising to the surface forming an island?
intraplate igneous activity
