Compare and contrast the caste system to democracy

ipn [44]

The caste system is a rigid social hierarchy based on ethnicity in Hindu society. A democracy is government by the people, where power is often exercised through elected representatives. In a caste system, certain voices are valued more than others, while in a pure democracy, all voices and votes are equal. The caste system is not a system of government, though, so it is inaccurate to make a comparison.

Question 5(Multiple Choice Worth 3 points) (02.01 MC) Wegener's theory of continental drift was formulated at a time when eviden

Sergio039 [100]

The correct answer is - Seafloor spreading at the mid-ocean ridge provides the mechanism for tectonic plate movement.

Harry Hess is one of the people that is most important when it comes to the proving and world wide acceptance of the continental drift theory.

Hess was very interested in the topic, and he was constantly looking for clues that would bring light to it and finally have a definite proof of it. While sailing through the Atlantic and doing some examinations, Hess noticed that there high mountains in the water, having flat peaks, and being arranged in an interesting manner. These underwater mountains, named guyouts, were the highest at a certain point, and than on both sides, as the distance was increasing they were becoming smaller and smaller.

What Hess stumbled upon was the seafloor spreading and how it works, and he recognized that quickly. He immediately went on to share what he discovered, that there's magma coming from bellow, solidifying and spreading, thus creating new crust while pushing the old crust away from the center, which is the reason why the continents are moving.

tester [92]

Answer:

The correct option is:

This scale rates an earthquake according to how much damage it causes.

Explanation:

The Mercalli Scale was invented by Giuseppe Mercalli in 1902. It is not considered that much of a scientific method to measure to measure strength of an earthquake.

Mercalli scale uses the observation of people who experienced the earthquake, to estimate the intensity. Its measurement is based on how much effect or damage it causes to the humans, objects, buildings, and other man made things.

It is not considered a good way to measure intensity of earthquakes because some witnesses may exaggerate the effects while some may consider it nominal.
