The statement Greenhouse gases are essential to support life on earth is true.
Further Explanations:
Greenhouse gases are gases that engross and emit radiant energy inside the “Thermal infrared” range. These gases results the greenhouse effect on Earth. Some major greenhouse gases in the Earth's atmosphere are water vapor, methane, nitrous oxide, and ozone and carbon dioxide
These gases are very essential for supporting life forms on Earth and have some vital role in the Earth’s atmosphere. Carbon dioxide and numerous other greenhouse gases act like a blanket, engrossing infrared radiation and prevent it from absconding into the outer space. This helps in the proper balancing of the biosphere and prevents any kind of disaster or any other happening.The overall hazardous effect of the steady heating of the Earth's biosphere is termed as global warming.

Greenhouse gases are indeed essential to supporting life on Earth. They play a crucial role in maintaining Earth's temperature by trapping heat in the atmosphere, a phenomenon known as the greenhouse effect. Due to human activities, the concentrations of these gases are currently increasing, causing shifts in the Earth's climate.
The statement that 'Greenhouse gases are essential to support life on earth' is True. Greenhouse gases, such as carbon dioxide, methane, water vapor, and ozone play a crucial role in maintaining the Earth's temperature by trapping heat in the atmosphere. This so-called 'greenhouse effect' prevents heat from escaping into space, similar to how the glass panes of a greenhouse function. In fact, without this effect, the Earth's average temperature would be over 30°C (nearly 60°F) cooler, which would not support the current forms of life on the planet.
Greenhouse gases absorb the sun's energy, some of which is emitted as infrared radiation. While some of this radiation escapes back into space, most of it is absorbed by the greenhouse gases and reflected back to the Earth. In this way, these gases help to maintain global temperatures within the needed range to sustain life. However, since the Industrial Revolution, human activities have been increasing the concentrations of these gases, significantly altering the Earth's energy balance and climate.
