Although the light year is a
commonly used unit, astronomers
prefer a different unit called the parsec (pc). A parsec, equal to 3.26
light years, is defined as the distance at which 1 Astronomical Unit subtends an
angle of 1 second of arc (1/3600 of a degree) When we use the parsec for really
large distances, we often put a prefix in front of it - like kiloparsecs (kpc),
which are equal to 1000 parsecs - or Megaparsecs (Mpc), equal to a million
parsecs.
The Milky Way is about 1,000,000,000,000,000,000 km
(about 100,000 light years or about 30 kpc) across. The Sun does not lie near
the center of our Galaxy. It lies about 8 kpc from the center on what is known
as the Sagittarius arm of the Milky Way.
Answer:
At present, the populations of richer and more developed countries do not destroy more forests than those of less developed countries, because thanks to their economic development they do not need new areas to exploit and, therefore, they conserve their natural areas without major modifications.
The poorer countries, on the other hand, use their natural resources as an economic asset, thereby greatly modifying their natural environment to meet their economic needs.

incomplete question. Here's the full question;
Which of the following best describes the impact weather has on the environment?
A. Average monthly temperatures vary widely in areas with the same latitude and physical features.
B. Weather is created by and impacts all four geospheres.
C. Annual precipitation levels do not impact weather around the world.
D .Weather and climate are impacted by the gravitational pull of the moon.
Answer:
<u>A. Average monthly temperatures vary widely in areas with the same latitude and physical features</u>
<u>Explanation:</u>
Remember, the question asks what<em> best</em> describes the impact weather has on the environment. Research has shown that the average monthly temperature may widely in areas that are in the same latitude.
Hence, this proves to show that the impact of weather on the environment isn't based on just latitude and physical features but on other factors like global warming.
