Western united states1
Western United States

  • There are 13 states in the Western Region

  • It is the largest region of the United States

Physical features
Physical Features

  • The Rocky Mountainsare North America’s largest mountain range.

    • Melting snow from the Rockies formed rivers including the Rio Grande, The Missouri, and The Colorado

    • Landforms vary greatly

  • Good land for farming

  • Tall Grass Prairiesfor ranching

  • Coastal areasfor fishing

  • Great Plains

  • Deserts

  • Basins

  • Volcanoes


  • Purchased from Russia in 1867 for $7.2 million

  • William Seward (Sec. of State) bought it

  • the 49th state - 1959

The hawaiian islands
The Hawaiian Islands

  • 8 major islands; 100 smaller

  • actually volcanic mountains “poking” through Pacific

  • 1900 became USA territory; 1959 became USA state (50th state)

What is this?

The Pacific Ring of Fire

The Ring of Fire 2:50

Climate weather1

  • Pacific Ring of Fire

  • Region is subject toearthquakes, volcano eruptions, and hot spots(In middle of a plate where magma reaches surface. Warms water and shoots steam into air known as Geysers)

  • Extreme variance in seasonal temperature and rainfall(Alaska to Hawaii!)

  • Semiarid Climatein 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 grasses; not completely arid.

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.

VolcanoesMt. 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.

Hot SpotsYellowstone 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).
