Signs of a tornado include a dark, greenish sky; large hail; a loud, continuous roar; and a rotating, funnel-shaped cloud. It's important to take shelter immediately if you observe these indicators.
Glitter is used in a tornado in a bottle to make the swirling motion of the liquid more visible and interesting to observe. The glitter particles help to make the movement of the liquid more visible as it mimics the look of a swirling tornado.
The great Natchez tornado of 1840 was classified as an F4 tornado on the Fujita scale, with estimated wind speeds of 260-319 mph. It was one of the deadliest tornadoes in U.S. history, causing significant damage and loss of life in the city of Natchez, Mississippi.
Tornadoes stop when the atmospheric conditions that sustain them, such as warm, moist air rising and interacting with cool, dry air, change. This can lead to a decrease in the rotation within the storm and ultimately cause the tornado to dissipate. Other factors like terrain or the interaction with other weather systems can also impact a tornado's longevity.
Yes, some people have survived tornadoes by seeking shelter in basements, storm shelters, or interior rooms of sturdy buildings. It is important to take tornado warnings seriously and have a plan in place to stay safe in the event of severe weather.
Geologists look for clues in rock formations, minerals, and fossils to understand the Earth's history, such as past climates, plate movement, and volcanic activity. They also search for valuable resources like oil, natural gas, and minerals to assess economic potential and environmental impact. Understanding the Earth's processes through careful observation and analysis helps geologists make predictions about future events and manage geological risks.
