πŸ“š Quick Study Guide

  • 🌍 Earthquakes: Earthquakes are vibrations caused by the movement of tectonic plates.
  • 🌊 Seismic Waves: These waves travel through the Earth and are measured by seismographs. There are P-waves (primary) and S-waves (secondary).
  • πŸ“ Epicenter: The point on the Earth's surface directly above the earthquake's focus (where it originates).
  • πŸŒ‹ Volcanoes: Volcanoes are formed when molten rock (magma) erupts onto the Earth's surface.
  • πŸ”₯ Magma vs. Lava: Magma is molten rock beneath the surface, while lava is molten rock that has erupted onto the surface.
  • 🌑️ Types of Volcanoes: Shield volcanoes (broad, gently sloping), composite volcanoes (steep-sided), and cinder cone volcanoes (small, cone-shaped).
  • πŸ“ Richter Scale: A scale used to measure the magnitude (size) of an earthquake. Each whole number increase represents a tenfold increase in amplitude.
