Warms water and shoots steam into air known as Geysers) • Extreme variance in seasonal temperature and rainfall (Alaska to Hawaii!) • Semiarid Climate in general in western states that fall in the contiguous 48 states sem·i·ar·id (s m - r d) adj. Characterized by relatively low annual rainfall of 25 to 50 centimeters (10 to 20 inches) and having scrubby vegetation with short, coarse 10 grasses; not completely arid. Climate/Weather The Pacific Ring of Fire Plate Tectonics 3:49 11 Climate/Weather The Ring of Fire Ring of Fire explanation 1:33 The large series of volcanoes (some active) encircling the Pacific Ocean are referred to as being part of the Ring of Fire, and notorious for frequent earthquakes and volcanic eruptions. The Ring of Fire, coinciding with the edges of one of the world's main tectonic plates, (the Pacific Plate) contains over 450 volcanoes and is home to approximately 75% of the world's active volcanoes. Nearly 90% of the world's earthquakes occur along the Ring of Fire; most recently, the devastating quakes in Chile, Japan and New Zealand.

St. Helens, Washington State • The 1980 eruption of Mount St. Helens was the most significant to occur in the contiguous 48 U.S. states in recorded history • The eruption was preceded by a two-month series of earthquakes and steam-venting episodes, caused by an injection of magma at shallow depth below the mountain that created a huge bulge and a fracture system on Mount St. Helens' north slope. • An earthquake at 8:32 a.m. on May 18, 1980, caused the entire weakened north face to slide away, suddenly exposing the partly molten, gas- and steam-rich rock in the volcano to lower pressure. The rock responded by exploding into a very hot mix of pulverized lava and older rock that sped toward Spirit Lake so fast that it quickly passed the avalanching north face.

Saint Helens 1:49 Landslide Hot Spots Yellowstone National Park “Old Faithful” • The Old Faithful geyser in Wyoming's Yellowstone National Park erupts about once every 65 minutes, much to the delight of tourists. • The water ejected during each eruption is at or near the boiling point, often reaches a height of 50 meters (approximately 170 feet), and has an estimated volume of 45,000 liters (12,000 gallons).
