1. What transitions has Earth gone through and why? The young earth was anything but habitable. Radioactive elements decaying within its mass and impacts from debris raining down form space generated intense heat. There was no life during this era. Is called the Hadean era and was formed about 4.5 billion years ago. Hadean comes from the Greek word Hades which means “Hell”. That’s how hot the Earth’s temperature was. The next phase in the Earth’s history was the Archean era. It existed

It is known that these storms are an act of nature by God’s laws at work. The term hurricane just stuck with the weather condition. Another source states

INTRODUCTION [SLIDE 2] Many chemical compounds found in the Earth’s atmosphere act as “greenhouse gases.” These gases allow sunlight to enter the atmosphere freely. When sunlight strikes the Earth’s surface‚ some of it is reflected back towards space as infrared radiation (heat). Greenhouse gases absorb this infrared radiation and trap the heat in the atmosphere. Over time‚ the amount of energy sent from the sun to the Earth’s surface should be about the same as the amount of energy radiated back
