CONVECTION CURRENTS

-
drives Earth's ocean currents, atmospheric weather and geology

TYPES OF VOLCANOES
Extinction: A Volcano that can never erupt again (has not erupted in the last 10,000 years)
Dormant: A Volcano that has seen activity in the last 10,000 years, but not seen activity in the last 400 years and still has the ability to erupt
Active: A Volcano that has erupted recently, or continuously eruptiing

TROPICAL STORMS

STRUCTURE
-
Eye and Eye wall
Eye wall is most devastating region where the most dangerous winds and intense rainfall occurs. It surrounds the eye of the storm.
The most calm part of Tropical storm at the center surrounded by the eye wall. Low rainfall and slower wind speeds

-
Coriolis effect
-
Rotation of Earth causes free moving of objects. forces winds to shift towards the right or left depending on the hemisphere
EARTHQUAKES
CHARACTERISTICS
-
-
-
Convection currents occur to move the different continents and when there are either Destructive plate boundaries, conservative plate boundaries, constructive plate boundaries and collision zone
-
SEISMOGRAPHIC NETWORK
Measured in Magnitudes based on the size of the earthquake and the destruction using Moment Magnitude Scale
