On March 27, 1980, a series of volcanic explosions and pyroclastic flows began at Mount St. Helens in Skamania County, Washington, United States. How did this eruption interfered with producers ability to make energy using the sun?

• by using up large volumes of nearby atmospheric oxygen

• by using up heat energy stored in Earth’s core

• by releasing dust that blocks sunlight from reaching Earth

• increases
• decreases
• stays the same
