Heyy.
So i did the alternative activity for this assignment.
In task one I only did part F:
answer:
Weathering damage on Cleopatra's Needle, an Egyptian obelisk in Central Park, New York City, is compared to known weathering rates of granites in various regions. The detrimental influence of the city's environment in 83 years of exposure has been attributed by textbook authors to damage to this coarse-grained foliated granite. As evidenced by the original depth of inscription in New York, about 11/2 inches of maximum surface reduction had occurred. Granite reduction rates in humid regions were calculated to be as low as 0.0076 mm per year, and even lower in deserts. The majority of the damage to the obelisk was caused by rising moisture laden with sulfate salts in Egypt, according to the findings. The hydration pressure of these salts, combined with frost wedging, is responsible for the major damage to the monument, which happened during its first few years in New York.
In task 2 I only did part D
answer:
Two independent sets of observations on sand activities in relation to the flowing river are recorded as the water passes through the meandering river. Stream abrasion can affect the morphology of a stream or river dramatically over time. Because the water can start erosion with anything near it, erosion can impact human communities near rivers.
MAKE SURE YOU SAY THAT YOU DID THE ALTERNATIVE ACTIVITY!!!!
Answer:
In the process of exploring the birth of the earliest galaxies in the universe, to understand the planetary systems, explore planets that are capable of supporting life, and to learn whether life began elsewhere in the solar system have helped us advance and build our civilization.
Answer:
No, it cannot
Explanation:
The Earth's gravitational force cannot do a positive or negative work on a geosynchronous communication satellite as long as it is on its circular orbit due to the fact that the gravitation force of the Earth is always at right angle to the orbital path.
Answer:
The dark colored moths were due to a genetic mutation, and were more than likely present before the Industrial Revolution. Their fitness was low because predators could easily see them on the light-colored trees. They would be eaten before they could reproduce and pass on their genetic mutation. After the trees became darkened by soot, the darker colored moths now had the survival advantage, able to "hide" from predators. The lighter colored moths became more visible to predators, and the advantage shifted. Now, the light colored moths were more visible to predators, were eaten, and didn't have the chance to reproduce. The darker moths with the mutation had the survival advantage, blending in with the soot-covered trees, and were able to reproduce at higher rates, passing the mutation on to later generations.
