-Mountains provide us with freshwater, energy, food, biodiversity, and medicinal products – resources that may become very rare in the coming decades. They are also very prone to climate changes, land degradation, deforestation and natural disasters.
Answer:
21.5%
Explanation:
to find the answer to this equation you must found out how much each of the areas are
the circles area is represented by pi*(5^2)
that is 25pi
or
25 * pi = 78.5398163
then you find the area of the square
10 * 10 = 100 (5 + 5 = 10)
you can directly subtract 78.5398163 from 100 because it can be portrayed as 100%
100 - 78.5398163 = 21.4601837
you must round to the nearest tenth so your answer is
21.5%
During Hadean time, the solar system was forming within a cloud of dust and gas known as the solar nebula, which eventually spawned asteroids, comets, moons and planets. Astrogeophysicists theorize that about 4.52 billion years ago the proto-Earth collided with a Mars-size planetoid named Theia.

Now, day by day new technologies are invented, causing more pollution than in the past. It is important now because we are developing in very fast steps and something should be done.
