Define Acid Rain.
Rainfall that is acidic made by atmosphere pollution that causes environmental harm.
Includes sulphur combined with atmospheric moisture.
Define Climate Change.
A change in global or regional climate patterns.
Type of mudflow or debris flow composed slurry, rock debris and water flowing down a volcano.
Extremely destructive.as lava combines with ice.
Large masses of wet or dry rock and soil that fall, slide or flow very rapidly under force of gravity.
Overflow of large amounts of water beyond its normal limits. Or a eruption may melt ice causing this mass flow of water.
Define Tsunami or Tidal Wave.
Series of waves in a water body caused by the displacement of a large volume of water generally in the ocean.

Example of Acid Rain from a volcano.
Volcano in Hawaii.
High concentration of sulfur dioxide produce volcanic smog causing persistent health problems.
Example of climate change from a volcano.
