Answer:

The earth is a vast, complex system powered by two sources of energy: an internal source (the decay of radioactive elements in the geosphere, which generates geothermal heat) and an external source (the solar radiation received from the Sun); the vast majority of the energy in the earth system comes from the Sun.

Question 9(Multiple Choice Worth 1 points) Which of the following actions might be taken to protect a species listed as endanger
Tems11 [23]

Answer:

II and III

Explanation:

A species is classified as endangered when it comes to a situation where the number of individuals within the species is so low that it might not be enough for it to reproduce properly and survive. Also, when species is listed as endangered, the chances are very high that the species will go extinct.

In order for the species to be saved, there are numerous methods that are used:

  • One thing is to make the hunting of the species illegal, usually making a very strict law that would fend off anyone tempted to do so.
  • Creating a special program for monitoring the species, where every individual will be tracked, constantly checked, and protected on the ground.
  • Any entry into the area where the species lives to be forbidden, except for scientific goals related to the species, and even for it to have a species permit.

Unfortunately, this doesn't always have the wanted effect, and despite all efforts some species go extinct, like it is the example with several species of rhinos in the past century. On the other hand, there are species that seem to be extremely resilient, and despite having very low numbers, they manage to survive, even if they don't have any particular rise in their populations, like it is the examples of the Iberian lynx and the Balkan lynx.

Very often, the method of breeding individuals in captivity of a species that is endangered is used. This is done so that there are controlled circumstances and no danger for the offspring, thus to maximize the chances of their survival. By using this method though, special programs are needed afterwards in order to prepare the young ones for life in the wilderness, which is not always successful.

Marianna [84]

Answer:

“Crust” describes  the outermost shell of a terrestrial planet. Our planet’s thin, 40-kilometer (25-mile) deep crust—just 1% of Earth’s mass—contains all known life in the universe.

Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. At the center of the Earth is a hot, dense metal core.

Earth’s layers constantly interact with each other, and the crust and upper portion of the mantle are part of a single geologic unit called the lithosphere. The lithosphere’s depth varies, and the Mohorovicic discontinuity (the Moho)—the boundary between the mantle and crust—does not exist at a uniform depth. Isostasy describes the physical, chemical, and mechanical differences between the mantle and crust that allow the crust to “float” on the more malleable mantle. Not all regions of Earth are balanced in isostatic equilibrium. Isostatic equilibrium depends on the density and thickness of the crust, and the dynamic forces at work in the mantle.

Just as the depth of the crust varies, so does its temperature. The upper crust withstands the ambient temperature of the atmosphere or ocean—hot in arid deserts and freezing in ocean trenches. Near the Moho, the temperature of the crust ranges from 200° Celsius (392° Fahrenheit) to 400° Celsius (752° Fahrenheit).
