Homographs are words that are spelled the same regardless of pronunciation (they may be pronounced the same or differently). Homonyms are words that are both spelled and pronounced the same. Therefore a homonym is both a type of homograph and a type of homophone. To be correct I believe the Venn diagram should have one circle labeled homograph and the other labeled homophone. The intersection should be labeled homonym.
An Excessive Heat Warning is issued when heat indices are expected to reach at least 105 degrees, except at least 110 degrees over Delmarva and far southern New Jersey (Salem, Cumberland, Cape May, and Atlantic Counties).
No other United States location has come close to experiencing such intense heat. Indeed temperatures over 120 degrees F (48.9 Â°C) are unusual events, even in the hottest places of the United States, except Death Valley. At the National Park's, weather station, now called Furnace Creek, the thermometer rises above 120 on five to twenty days a year.
