4 INNER LAYERS OF THE EARTH
1.) Crust2.) Mantle3.) Outer Core4.) Inner Core
THEORY OF PLATE TECTONICS
Alfred Wegener and his theory of plate tectonics
Many scientist felt that the land features were fixed on Earth.
Wegener felt that all the Continents were one big land mass (Pangaea)that drifted apart.
MAP EXERCISE
TYPES OF FAULT BOUNDARIES
Convergent Boundaries
Divergent Boundaries
Transform Boundaries
CONVERGENT BOUNDARYWhen two tectonic plates collide and one plate is forced under the other.
DIVERGENT BOUNDARIESType of fault where two plates are moving away from each other.
TRANSFORM BOUNDARYWhen plates slide past one another and crust is neither created nor destroyed. Form on the boundary of tectonic plates.
EARTHQUAKES!
The sudden release of energy in the earth’s crust that creates a seismic wave.
AN EARTHQUAKES POWER…
TSUNAMIS
Large waves caused by earthquakes or a sudden volcanic eruption.
VOLCANOES!
TYPES OF VOLCANOES
-Shield Volcanoes
--Cone Volcanoes
--Composite Volcanoes
--Super volcanoes
SHIELD VOLCANOES
Broad, Flat volcanoes that oozes thick, low viscosity lava.
CONE VOLCANOES
Steep volcanoes that are layered with fast cooled magma.
COMPOSITE VOLCANOES
Tall cone shaped volcanoes, made from eruptions thousands of years ago. EX: MT. Fuji, Japan
SUPER VOLCANOESNew theory about magma chambers blocked off that will build pressure and explode. They are mostly located on land. Is there a super volcano in the U.S.?
