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.

Explanation:
The Relationship between Rainfall and Temperature. The physical rationale behind the relationship between rainfall and temperature is that rainfall may affect soil moisture which may in turn affect surface temperature by controlling the partitioning between the sensible and latent heat fluxes [41].

Answer:
Improved agricultural practices have led to increased productivity, decreased organic production, increased health risks, increased water pollution, and increased profits.
Explanation:
Since the turn of the 20th century, agriculture has experienced numerous changes and is much different nowadays than it used to be. This has been due to rapid technological development, which has also improved agricultural practices. The improvements have been in every sphere, from the protection of the plants to create more resistant and plants that have higher productivity, better irrigation, mechanization, bioengineering, and at the end of it all it has led to higher profits.
The developments in genetics have led to the creation of plants that are more resistant to diseases and have higher productivity. The pesticides, herbicides, and fungicides have all helped in the protection of the pants and destruction of pests, which further led to an increase in production, but their usage has also led to pollution of the soil and water. Unfortunately, the usage of chamicals has led to increased health risks, and significantly lowering the organic production which was dominating before.
