The correct answer is: D. so big
The United States is so big that it spans five time zones: Eastern, Central, Mountain, Pacific, and Alaska. This is because the Earth rotates on its axis once every 24 hours, and the sun appears to move across the sky from east to west. As the sun moves across the sky, it crosses different time zones, and each time zone is one hour ahead of the one before it.
The United States is so big that it takes the sun about 4 hours to cross the country from east to west. This means that when it is noon in New York City, it is 11:00 AM in Chicago, 10:00 AM in Denver, 9:00 AM in Los Angeles, and 8:00 AM in Honolulu.
The five time zones in the United States are:
- Eastern Time Zone (ET): This time zone is used in the eastern part of the United States, including New York City, Washington, D.C., and Boston.
- Central Time Zone (CT): This time zone is used in the central part of the United States, including Chicago, Dallas, and Houston.
- Mountain Time Zone (MT): This time zone is used in the western part of the United States, including Denver, Salt Lake City, and Phoenix.
- Pacific Time Zone (PT): This time zone is used in the western part of the United States, including Los Angeles, San Francisco, and Seattle.
- Alaska Time Zone (AK): This time zone is used in Alaska.
The United States is not the only country that spans multiple time zones. Other countries that span multiple time zones include Russia, Canada, China, and India.
