The statement is - True.

The Ohio-Missouri-Mississippi (also referred to as MOM) River System is the largest and most significant river system in North America. The main river in this system is the Mississippi River, so the river system is most often referred to as just Mississippi RIver System and Missouri and Ohio rivers as one its biggest tributaries as well as the Arkansas, Illinois, and Red rivers. This system drains 41% of the USA and little of Canada as well. It has a big economic importance for the USA because 60% of the grain, 22% of oil and gas, and 20% of coal shipments are through it. Also if some measures are taken like reducing the meanders, correcting parts of the banks, regulation of the floodings, this river system will be by far the most economically important river system in the world by being able to support ships far inland into the US.

HELP PLS ASAP! age of continental and oceanic plates...
saul85 [17]
The Earth's rocky outer crust solidified billions of years ago, soon after the Earth formed. This crust is not a solid shell; it is broken up into huge, thick plates that drift atop the soft, underlying mantle.

The plates are made of rock and drift all over the globe; they move both horizontally (sideways) and vertically (up and down). Over long periods of time, the plates also change in size as their margins are added to, crushed together, or pushed back into the Earth's mantle. These plates are from 50 to 250 miles (80 to 400 km) thick.

Why would the French Government limit movies imported from other Nations
Bas_tet [7]
France is the birthplace of cinema and was responsible for many of its significant contributions to the art form and the film-making process itself.[3] Several important cinematic movements, including the Nouvelle Vague, began in the country. It is noted for having a particularly strong film industry, due in part to protections afforded by the French government.[3]

Apart from its strong and innovative film tradition, France has also been a gathering spot for artists from across Europe and the world. For this reason, French cinema is sometimes intertwined with the cinema of foreign nations. Directors from nations such as Poland (Roman Polanski, Krzysztof Kieślowski, and Andrzej Żuławski), Argentina (Gaspar Noé and Edgardo Cozarinsky), Russia (Alexandre Alexeieff, Anatole Litvak), Austria (Michael Haneke), and Georgia (Géla Babluani, Otar Iosseliani) are prominent in the ranks of French cinema. Conversely, French directors have had prolific and influential careers in other countries, such as Luc Besson, Jacques Tourneur, or Francis Veber in the United States.

Another element supporting this fact is that Paris has the highest density of cinemas in the world, measured by the number of movie theaters per inhabitant,[4] and that in most "downtown Paris" movie theaters, foreign movies which would be secluded to "art houses" cinemas in other places are shown alongside "mainstream" works. Philippe Binant realized, on 2 February 2000, the first digital cinema projection in Europe, with the DLP CINEMA technology developed by Texas Instruments, in Paris.[5][6][7] Paris also boasts the Cité du cinéma, a major studio north of the city, and Disney Studio, a theme park devoted to the cinema and the third theme park near the city behind Disneyland and Parc Asterix.[8]

France is the most successful film industry in Europe in terms of number of films produced per annum, with a record-breaking 300 feature-length films produced in 2015.[9] France is also one of the few countries where non-American productions have the biggest share: American films only represented 44.9% of total admissions in 2014. This is largely due to the commercial strength of domestic productions, which accounted for 44,5% of admissions in 2014 (35.5% in 2015; 35.3% in 2016).[10] Also, the French film industry is closer to being entirely self-sufficient than any other country in Europe, recovering around 80–90% of costs from revenues generated in the domestic market alone.[11]

Briefly describe the characteristics of the four main layers of Earth. Include temperatures.
Mnenie [13.5K]

Answer:

Crust

The crust is the first layer of the earth. It is split up into two parts the continental crust, and the oceanic crust. The oceanic crust takes up 71% of the earths crust, and the other 29% of the crust is continental. The continental is made up of igneous rocks, and the oceanic crust is made up of sedimentary and basalt rocks. The continental crust is older than the oceanic crust, some of the rocks are 3.9 billion years old. The density average of the oceanic crust is 3g/cm. The average density of the continental earth is 2.7g/cm. The temperature of the crust is around 200-400 degrees celsius. The crust is about 60 km thick under a continent and 5 km thick under the ocean. The crust is constantly moving.  The crust doesn't even make up 1% of the earth!  The crust is the layer were tectonic plates can be found.

Mantle

The mantle is the second layer of the earth. It is split up into two different parts, the lithosphere (which is the top part) and the asthenosphere (which is the bottom part). The lithosphere is a dense rock made out of iron and nickel, the asthenosphere is a plastic like fluid. The temperature of the lithosphere is around 300 to 500 degrees celsius, and the asthenosphere is around 4500 degrees celsius. The mantle has the biggest volume of all the layers, the volume of it is 84% of the earth. It is 1,800 miles deep or 2,900 kilometers deep. In the mantle are convection currents which make the mantle move. The lower mantle heats up and rises and cools down then gets pushed down because it is heavier. Then I keeps going on like that. The mantle grows a meter a year.

Lithosphere

The lithosphere is the top layer of the mantle. The lithosphere includes having the crust in it. It is a cooler layer because it is farther from the inner core. The lithosphere is a dense rock made out of iron and nickel. The temperature of the lithosphere is 300-500 degrees celsius. Inside the lithosphere and asthenosphere are currents, called convection currents. They make the lithosphere and asthenosphere turn round and round. So because the lithosphere is denser it is being forced down closer to the core and then heats up then forces its way back up to the top because it is less dense.

Asthenosphere

The asthenosphere is the bottom layer of the mantle. It is a plastic like liquid made up of iron and nickel. The temperature of the asthenospere is 4500 degrees celsius. It is hotter than the lithosphere because it is closer to the inner core. Inside the asthenosphere and lithosphere are currents, they are called convection currents. So because the asthenosphere is less dense or lighter than the lithosphere is forces its way up to the top and foces the lithosphere down. It then cools down then gets forced back down by a hotter substance

Convection Currents

Convection Currents happen in the Mantle. They go through bot the lithosphere and the asthenosphere. They make them move round and round. Since the asthenosphere is hotter, that makes it lighter or less dense, so it forces its way to the top. Meanwhile it is forcing the lithosphere to go down and take it's place, So the asthenosphere that moved up and cooled down, and the lithosphere that got forced down is heating up and then when it gets hot ebough it will force its way to the top and the whole cycle will start again. But these convection currents effect the earth and the tectonic plates. Because when the plates, say...... overlap one gets pushed under the other, and it would get pushed don to the convection currents, and because it is a dense material it would be forced down and it would melt and make a new crust. In the photo below that diagram would acctually be going on inside of the earth at this very moment!

Outer core

The outer core is a liquid made up of iron and nickel. The temperature of the outer core is around 4400 degrees celsius. The depth of the outer core is 2, 890. This is one of the three layers that is putting pressure on the inner core. It is the second hottest layer, because it is the layer above the inner core, and it is the second farthest from the surface of the earth. Also it is said that the core is rotating faster than the rest of the earth but...... slower than previously believed! the outer core was discovered in 1936 by seismologist, Inge Lehmann.

Inner core

The Inner crust is the second thinnest layer. The inner core is hotter than the surface of the sun. The inner core is made out of iron and nickel. It is 5159 to 6378 km thick. The inner core is extremely hot and is the last layer. The inner core is 5505 degrees celsius. It is a solid because of all the pressure from the other layers putting there weight onto this layer. The inner core grows. The core was discovered in 1971..
