Answer:
Regardless of its name, the Big Bang theory found widespread acceptance for its unparalleled ability to explain what we see. The balance of light with particles like protons and neutrons during the first 3 minutes, for instance, let early elements form at a rate predicting the current amounts of helium and other light atoms.
"There was a small window in time where it was possible for nuclei to form," said Glennys Farrar, a cosmologist at New York University. "After that, the universe kept expanding and they couldn't find each other, and before [the window] it was too hot."
A cloudy plasma filled the universe for the next 378,000 years, until further cooling let electrons and protons form neutral hydrogen atoms, and the fog cleared. The light emitted during this process, which has since stretched into microwaves, is the earliest known object researchers can study directly. Known as the cosmic microwave background (CMB) radiation, many researchers consider it the strongest evidence for the Big Bang.
Answer:
"water, air, sunlight, soil, plants, microorganisms, insects and animals. Ecosystems may be terrestrial – that is, on land – or aquatic. Sizes of ecosystems vary; they could entail a small puddle or an enormous swath of desert. Likewise, natural ecosystems can look quite different from one another."
Explanation:
Answer:
chemical spills can have major environmental impacts. Spilled oil and other chemicals can physically damage marine life with run-off contamination in the water. ... Spilt chemicals can also run-off into soil, causing severe ecological damage and making such areas inhabitable for flora and fauna.
Explanation:
Answer:
Volcanoes and Earthquakes occur more frequently where tectonic plates meet or separate
Explanation:
Volcanoes do occur underwater at mid - oceanic ridges but it often occurs when the plates are separating and this usually forms new islands
