Describe the regions of the oceanic lithosphere, including the continental shelf, continental slope, and abyssal plain.

The oceanic lithosphere consists of the upper part of the Earth's crust that is submerged beneath the oceans. It is primarily made up of basalt, but can consist of other forms of sediment deposited by rivers or currents; the basalt feature exists due to the oceanic lithosphere's creation via divergent tectonic activity. The continental shelf is a portion of the crust that is of higher elevation than the rest of the ocean due to its connection to the less dense continental lithosphere. The continental slope, therefore, is the portion of the crust where the continental shelf decreases in elevation as it meets the denser oceanic lithosphere. Abyssal plains are portions of the lithosphere far from spreading centers - they consist of rocks older than those near rifting centers. Due to the coolness of the plate and their distance from rifting centers, abyssal plains are some of the lowest continuous portions of the lithosphere (cool rock is denser and thus sinks to a lower elevation). Since they are very much inactive, abyssal plains are coated with sediment and are very, very flat.

More than 75 percent

Explanation:

Let us carefully analyze this problem:

The half life of the rubidium isotope = 50 billion years

The half-life of a radioactive isotope is the time it takes for it to decay to half of its original amount.

Every 50years, we know that a rubidium isotope would split into half.

Initially when the isotope was formed, we would only have the parent atoms there. There wont be any daughter;

ratio of parent to daughter = 100 : 0

When the isotope decays to half; we would have equal number of parent and daughter:

ratio of parent to daughter at half life = 50 : 50

The age of the earth is about 4.6billion years;

this is;

$\frac{4.6}{50}$ x 100 = 9.2% of the half-life of the rubidium isotope.

At this time, we should know that only 9.2 percent of the daughter would have been formed.

The remaining parent would be 100 - 9.2 = 90.8% would still be left undecayed.

The ratio of parent to daughter = 90.8 : 9.2

This is more than 75% of the parent

What has created resentment in some tourist areas?

Elza [17]

Answer:

The gentrification and class differences are the main point of resentment against tourism in some areas.

Explanation:

While tourism is good for the economy of the country, the common people who work in the tourist industry do not gain much, especially in the poorer countries. Many of the places in these countries have recently become very popular (especially due to the internet) among wester, rich tourists. This ends up making the gap between the rich and poor bigger – class differences start standing out more, and people start feeling animosity.

Local people also often see tourists coming to their home countries looking for something “unique” and “exotic” and seeing their lives (and sometimes poverty) as a playground. They come for a certain time to see how life is and can return to their rich, western lives, while local people stay there. Tourists also sometimes do not respect local customs and ideas, which angers people.

Tourism often affects local customs in the sense that they become more massive and change. There are many beliefs, rites, and customs that have been changed with the rise of tourism as they need to be performed for those who come to observe it (for example, Day of the death in Mexico wasn’t paraded before as it is now, or St. Patrick’s celebration in Ireland which is more product of North American tourists with an Irish background and it departs with traditional celebrations).

Finally, as tourism becomes more massive, it affects the ecosystem. There are big changes in pollution, as well as disruption of normal growth of plants and animals. Many of the touristic areas that are popular today used to be small settlements, adapted into the environment. As more people arrive to visit these places, everything in nature is affected.

All of this results in the rise of resentments towards tourism in certain areas. While people know they need tourism to survive, they do not like the effects it has on their communities and life.
