A. Cosmology
Cosmology means the study of the cosmos, cosmo- means of or relating to the universe, therefore cosmology means the study of the universe. So it is the correct answer.
Answer:
The seafloor is younger at the mid-ocean ridge, and as it gets further away from it is older and older.
Explanation:
The seafloor and its characteristics is one of the best evidence when it comes to the theory of plate tectonics. This was first noticed by Alfred Wegener and later by any other scienticsts that have been interested in this theory. Basically, the evidence lies in the fact that the seafloor is the youngest at the active mid-ocean ridge, and the further it is from it it gets older and older, with the oldest seafloor being found at the subduction zones.
The reason for this is the manner in which the seafloor forms. The high activity in the mantle below manages to break the crust of a preexisting plate and divide it. It pushes enormous amouns of magma toward the surface constantly for millions of years. The magma quickly solidifies and creates new seafloor as it gets in touch with the water. The magma that comes through pushes the already consolidated one aside and the process goes on for millions of years.
Answer: B
Thermal Stress will weaken rock formations due to expansion and contraction from temperature changes.

<span>Hurricanes just don't come out of nowhere to become what they are. They go through a process of development that involves several different stages. These stages can have different lengths just as in human development depending on certain environmental conditions where it is located at a particular time. If these conditions are right, a hurricane can develop rapidly, and go through these early stages very quickly. If these conditions aren't right, then development can be slow, or not
at all. Here are the various stages of development a hurricane goes through.</span>

<span>Tropical Wave--These are the most common of tropical disturbances with about 100 forming each season. They lack a closed circulation, which is when there are winds in every direction. Wind speeds are less than 20 knots, or 25 mph.
</span><span>Tropical Depression--A wave becomes a depression when there is a presence of a closed circulation, and sustained winds are 20 knots, or 25 mph. At this point, the system is still quite disorganized.
</span><span>Tropical Storm--A depression becomes a tropical storm when shower and thunderstorm activity moves over the closed circulation, and sustained winds reach at least 35 knots, or 39 mph. At this point, the system is capable of causing minimal damage.
