Science 4th QE

• Andrija Mohorovicic - Discovered that seismic waves from distant earthquakes reach the seismographs faster than those from nearby earthquakes.
• Mohorovicic Discontinuity - The boundary between the mantle and crust
• Beno Gutenberg - Discovered an abrupt change in seismic waves from 2,900 km below the surface that recorded by seismographs all over the world.
• Gutenberg Discontinuity - The Core and Mantle boundary
• Elastic Rebound Theory - Explains the occurrence of earthquakes
• Elastic rebound - The return of the rock to its original shape after elastic deformation
• Modified Mercalli Scale - Used to describe the intensity of an earthquake
• Typhoons - Strong circulating wind systems over the tropical oceans that bring strong winds, heavy rain, and large ocean waves
• Coriolis Effect - Spinning motion due to the rotation of the Earth
• Eye wall - Most destructive section of the typhoon
• Rainbands - Consists of clouds and precipitation
• Asteroids - Irregularly shaped metallic rocky bodies that are fragments from the formation of planets
• Asteroid belt - Region between the orbits of Mars and Jupiter
• Comets - Small celestial objects made mostly of ice, dust, and gas
• Meteorites - A piece of space debris that enters the atmosphere and burns up
• Kuiper Belt - Where comets are located in
• Oort Cloud - The outermost region where long-period comets originate
• Meteoroids - small pieces of rock and metal that are left over from the formation of the solar system.
• Meteor - Glowing meteoroids
• Meteor Shower - When the number of meteors increases dramatically
• Tropical Disturbance - A cluster of thunderstorm over the tropical oceans
• Low Pressure Area - A weather system that is created beneath the warm humid, rising air on the surface of the temperature
• Eye - The center of the typhoon. It is a cloud-free area with sinking cool air and light winds
• Inner Rainbands - Thick clouds that are not scattered and move inward toward the center.
• Outer Rainbands - The outer spiralspiral bands of the typhoon with clouds that are scattered but moving toward the center
• Tropical Depression - Tropical cyclone with maximum sustained winds up to 61 kilometers per hour
• Tropical storm - Tropical cyclone with maximum wind speed of 62 to 88 kph
• Severe Tropical Storm - Tropical cyclone with maximum wind speed of 89 to 117 kph
• Typhoon - Tropical cyclone with maximum wind speed of 118 to 184 kph
• Super Typhoon - Tropical cyclone with maximum wind speed of 185 kph or higher
• Storm Surge - Large ocean waves brought about by the swelling of the ocean water due to the low pressure center of a tropical cyclone
• Rain Gauge - Instrument that measures that amount of rainfall
