<h2>
Answer: C) stars in these regions are hidden by interstellar dust grains.</h2>
Explanation:
Some areas of the Milky Way seem dark because those are areas of the galaxy that are hidden by huge columns of interstellar dust that we cannot see through the visible range of the electromagnetic spectrum (which is the range in which our eyes see).
However, to solve this problem, astronomers use telescopes that work in the range of infrared and radio waves, to observe a little more through this intersetelar dust.
I think it is because the earth produces its own opposing gravitational force.
The number that Colorado River would have to downcut per year to form the mile-deep canyon in 4 million years is 0.40 millimeter per year.
Depth of canyon = 1 mile
Time taken = 4 million years
Based on the above information, the rate will be:
= Depth / Time taken
= 1 mile / 4 million years
= 0.25 mile / million year
Note tha<em>t 1 mile = 1609344 millimeter</em>
<em />
Therefore, the rate will be:
= (0.25 × 1609344) / 1000000 years
= 0.40 millimeter / years
In conclusion, the rate is 0.40 millimeter per year.

The Gaia hypothesis proposes that the Earth is a self-regulating intricate structure which involves the atmosphere, the hydrospheres, the biosphere, and the pedosphere, firmly paired as an evolving system. The aforementioned hypothesis claims that this system, called Gaia, looks for a chemical and physical environment that is best for contemporary life as a whole. A lot of processes in the Earth's surface crucial for the conditions of life rely on the interaction of living forms with elements that are inorganic. These processes indicate a global control system that controls Earth's surface atmosphere, temperature, ocean salinity and composition, which is powered by the global thermodynamic disequilibrium state of the Earth system.
