What is the missing first step of the following process:  -  Under the right conditions it can develop further and start to spin around a low-pressure center - If it develops it&#x27;s classified as a &#x27;tropical cyclone&#x27; or &#x27;tropical depression&#x27; - If the system strengthens and wind speeds rise past 39 mph, the system is dubbed a &#x27;tropical storm&#x27; - If the pressure in the center drops even further and the winds really pick up and forms a clearly defined &#x27;eye&#x27; it&#x27;s a hurricane -
Ans: A hurricane usually starts as an organized thunderstorm activity that stretches at least 100 miles across and maintains its identity for more than 24 hours

What is the missing first step of the following process:  -  The boiler produces steam under high pressure - The steam generated in the boiler flows down into a cylinder - Just ahead of the wheels, pushing a tight-fitting plunger, the piston - The piston is connected to one or more of the locomotive&#x27;s wheels through a kind of arm-elbow-shoulder joint called a crank and connecting rod - As the piston pushes, the crank and connecting rod turn the locomotive&#x27;s wheels and power the train along - An outlet valve opens and the piston pushes the steam back through the cylinder and out up the locomotive&#x27;s chimney -
