Convergent BoundaryHimalaya Mountains

Causes and Effects: Convergent boundary, when two parts of the earth move toward each other and the the land raise up because of the pressure. The effects is a new mountain was built.

Subduction Zone

Mariana Trench

CAUSES & EFFECTSWhile the oceanic crust is more dense than the continental crust, the oceanic will subduct under the continental and create trenches and volcanoes.

Divergent BoundaryGreat Rift

Valley

CAUSES & EFFECTSDivergent boundary is when two plates of the crust move apart from each other, and it create rift valley, mid-ocean ridge and sea-floor spreading.

Transform Boundary

CAUSES & EFFECTSTransform boundary is when two plates of the crust slide pass each other to create earthquake in the region.

San Andreas Fault

Fault Zone

Hanging Hills

CAUSES & EFFECTSThere are three different types of faults, normal fault, reverse/thrust fault, and strike-slip fault. The hanging hills is the result of normal fault, that one plates move downward.

Earthquake

Sichuan, China2008.May.12

CAUSES & EFFECTSBecause the transform boundary and fault caused the land to slide pass each other then lead to the strong movement of the land, which is the earthquake.

Tsunami

Japan 2011

CAUSES & EFFECTSTsunami is because the movement under the ocean of the oceanic crust like subduction zone, and cause huge harbor wave that bring massive damages and destruction.

Hot SpotHawaii

, Kailua

CAUSES & EFFECTSBecause the convection current in the mantle, when the magma is moving they shoot up to the crust too, and became volcanoes, if the magma still connect with the volcanoes, it will become a hot pot, which means it is an area with great heat and the volcano is alive.

Analysis Topics Definition

Convergent Boundary It is when two plates of the crust move toward each other and create mountains, deep-sea trench and subduction zone, one example is the Himalaya Mount.

Subduction Zone Result of convergent boundary, when the oceanic crust is more dense than the continental, it subduct. One example is the Mariana Trench

Divergent Boundary It is when two plates move apart from each other, and creates mid-ocean ridge, rift valley and sea-floor spreading.

Transform Boundary It is when two plates slide pass each other, and create earthquakes.

Fault Zone There are 3 types of fault, normal fault(downward), reverse fault(upward), and strike-slip fault(slide pass).

Earthquake Result of transform boundary, three types of waves, p wave, S wave and L wave.

Tsunami Earthquake that happens under the ocean and brings a huge sea wave to the land with severe damage.

Hot spot Because of the convection currents, after the magma shoot up to the land and still connect to the magma and create a volcano that is not dormant.
