<u>Answer:</u>
Rising sea levels recorded due to melting glaciers can be considered an observable indication of global warming
<u>Explanation:</u>
The glaciers in the sea are melting due to global warming.This is occurring due to the increase in the global temperature. Year after year, higher temperatures are being recorded and this heat in turn is melting the Arctic glaciers thus adding on to the level of the oceans.
The increased temperature will also disrupt the fauna and floral life. All automobiles don't necessarily have to contribute to global warming. There exist eco-friendly automobiles as well.
The five key features of tornadoes are formation, speed, vacuums, location and dust devils. They usually form in large thunder clouds. Their internal winds begin to whirl forming a funnel. The speed at which the funnel spins can be 400 km/hr making them the fastest winds on earth. The funnel acts like a giant vacuum sucking up debris and dirt as it goes. They usually only last about 15 minutes but can cover over hundreds of kilometers in that time. The primary location of tornadoes is in the United States in the Mid-Western states. If it develops over sea it is called a waterspout with winds up to 80 kph. In deserts where there is not as much water, small sandstorms known as dust devils are produced by whirling winds.
Major Key Fact: A tornado will sound like a roaring train. It is a deafening roar.
