- B.
3.5 million years ago
- C.
3.5 billion years ago
- D.
5.4 billion years ago
Correct Answer
C. 3.5 billion years agoExplanation
Fossils found in Australia indicate that life existed on Earth around 3.5 billion years ago. This is supported by scientific evidence and research conducted on these fossils. The age of the fossils is determined through various dating methods, such as radiometric dating, which measures the decay of radioactive isotopes in the rocks surrounding the fossils. These findings contribute to our understanding of the early evolution of life on Earth and provide valuable insights into the history of our planet.Rate this question:

_____________________________ is the warming of the earth due to build of Carbon Dioxid in the air.
Correct Answer
Global WarmingExplanation
Global warming refers to the increase in the Earth's average temperature caused by the buildup of carbon dioxide and other greenhouse gases in the atmosphere. These gases trap heat from the sun and prevent it from escaping back into space, leading to a gradual rise in global temperatures. This phenomenon has various negative effects on the environment, including melting ice caps, rising sea levels, and extreme weather events. It is a significant concern for the planet's ecosystems and human societies, and efforts are being made to reduce greenhouse gas emissions and mitigate its impact.Rate this question:
