9. Which forces do scientists believe are responsible for the movement of Earth's
tectonic plates?

Answers

The main reason why the tectonic plates move is the conversational currents. There is magma between the upper mantle and the asthenosphere that heats up at the upper mantle. The weight is so small that the magma rises with the help of these conversational currents. When the magma has ascended towards the asthenosphere, it has nowhere to go so the magma lies along the asthenosphere. There the magma cools down again because the asthenosphere is colder than the upper mantle, which makes the magma heavier and goes back down to the upper mantle, where the magma heats up again and everything starts all over again and so it goes on over and over again. Scientists have concluded that the earth's gravity causes two other processes that also cause the tectonic plates to move.

Ridge push - in the spreading zones, the sides of the tiles are raised and slide to the side as in a slide.
Slab pull - when a plate is pulled down by gravity in a subduction zone like an anchor.

Which is not a result of the multiplier effect of an American soft drink building up its operations in Romania?

a.greater need for plastics makers


b.more entrepreneurs


c.more demand for printers


d.higher unemployment

Answers

Answer:

Higher unemployment is not a result of the multiplier effect of the given situation.

Explanation:

If an American company opens up facilities in Romania for soft drinks, the effects on the Romanian economy will be positive. Building up such operations will result in a chain reaction as multiple sectors in the country will receive a boost because of the demand of the company for materials and services.

The employment will increase in the country. Not just people that are directly employed by the company itself, but because it will use numerous materials and services from other companies and industries, the chances are that more people will be employed in them as well. Another thing to which this company will result will be greater competition on the market, which leads to higher quality products for lower prices.

Which of the following explains the role of commodity chains in the average size of farms?


A. The spatial organization of agriculture has changed because of an increase in the number of farms as farmers join local commodity chains that regulate supply and demand for agricultural products and large profits can be realized.



B. The spatial organization of agriculture has remained stable, but farm productivity has increased through technological innovations that are available to farmers through membership in local commodity chains.



C. Commodity chains have led to changes in the spatial organization of agriculture from dispersed family farms to large corporate farms that produce, process, and distribute the products.



D. Farms are increasing in size, but there is little change in the spatial organization of agriculture because of the instability of regional cooperatives and associated commodity chains that cannot meet the demand for new products desired by consumers.


E. Commodity chains have had no effect on the spatial organization of agriculture because they operate only in areas of grain farming; dairy and meat products spoil rapidly and markets are too far away for safe and rapid transportation of those products.

Answers

Answer:

C

Explanation:

Commodity chains have led to changes in the spatial organization of agriculture from dispersed family farms to large corporate farms that produce, process, and distribute the products.

Working the ground, sowing seeds, and cultivating food plants are all examples of farming. Agriculture is another term for raising livestock for meat and dairy products. The word "agriculture" is a good way of defining the manner of work and life of those who work in the agriculture business.

The correct answer is C. Commodity chains have created a shift in economic spatial configuration from dispersed family farms to multinational corporate farms that produce, process, and export goods.

This is the correct answer because this best explains the role of the commodity chain in the average size of farms. A product chain is a corporate process that involves acquiring resources, converting them into goods or commodities, and then distributing them to customers.

It is a set of linkages that interconnect the several places of manufacture and distribution to produce a product that is then traded on the global market.

B. centrifugal force

Answers

Answer:

This is an example of a centripetal force.

Explanation:

Centripetal force, in human geography, is a term that describes actions and processes that lead to unity among the people of a country or a region. Basically, a factor that is able to create a sense of unity and hold people together would be a centripetal force. Religion has often acted like a centripetal force in many countries and regions around the world, and one good example is Mexico.

Mexico has around 90% of its population as followers of Roman Catholicism. This religion came with the Spanish colonizers. It was not just the Spanish that practiced it though, but instead, there was assimilation or even total destruction of the native religions in order to make the colony as homogenous religiously as possible. This led the vast majority of the population in the colony, now an independent country, to follow just one religion, which gave them a sense of unity as they had something they shared on a deep and intimate level.

What are terrestrial planets?

Terrestrial planets include Mercury, Venus, Earth, and Mars because of their compact, stony surfaces that resemble terra firma on Earth. The four innermost planets in the solar system are the four terrestrial planets.

The term "terrestrial planet," "telluric planet," "solid planet," or "rocky planet" refers to a planet that is predominantly made of silicate rocks or metals. The inner planets Mercury, Venus, Earth, and Mars are closest to the Sun and are recognized by the IAU as terrestrial planets.

Earth-sized and smaller terrestrial planets are rocky, silicate, water, and carbon-based worlds.

The terrestrial planets (Mercury, Venus, Earth, and Mars) are distinguished into three layers: a metallic core, a silicate shell (mantle and crust), and a volatile envelope of gases, ice, and, for the Earth, liquid water.
