Answer:

The correct answer is A) ozone

Explanation:

Ozone(O₃) is a layer made up of 3 oxygen molecules and present in the stratosphere layer of atmosphere. The ozone layer absorbs most of Sun's ultraviolet rays and protect us from UV radiation. These ultraviolet light are harmful to animals and humans and can cause skin cancer.

In the stratosphere, ozone is continuously converted into molecular oxygen by UV radiation which breaks O₃ into O₂ and O. Then again this O₂ converts into O₃ so the process is interchangeable.

The radiation blocked by ozone cause the heating of the stratosphere so ozone plays important role in maintaining the temperature of the earth's atmosphere.

1. When did fires first show up in Yellowstone's history and how often did they occur each year on
S_A_V [24]
The Yellowstone fires of 1988 collectively formed the largest wildfire in the recorded history of Yellowstone National Park in the United States. Starting as many smaller individual fires, the flames quickly spread out of control due to drought conditions and increasing winds, combining into one large conflagration which burned for several months. The fires almost destroyed two major visitor destinations and, on September 8, 1988, the entire park closed to all non-emergency personnel for the first time in its history. In an average year, approximately 21 fires are ignited in Yellowstone by lightning. About 75% of fires in Yellowstone never reach more than 0.1 hectares (0.25 acres) in size
