Briefly describe the characteristics of the four main layers of Earth. Include temperatures.
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..

Using your own knowledge. Examine the primary and secondary effects of an earthquake or volcanic eruption that you have studied.
Answer:
The primary effects of earthquakes are caused by the surface rupture along the fault and by the ground shaking via the earthquake energy release. The secondary effects are the effects that occur directly as a result of this earthquake shaking and energy release, i.e., the onset of a tsunami wave, or a landslide.

Answer:
In a market economy, the supply and demand determine for whom goods and produced.
Explanation:
There are multiple different economic types, all of which have experienced spikes and popularity, but some also decline. One of the economic types that seem to have been taking over the world since the past century and still continues to do so, is the market economy.
The market economy is an economic type where the businesses are privately owned, and the government only has a regulatory role so that laws are not broken and to protect the people. Also, the businesses have total freedom to decide what, how much, and in which manner to produce goods and where to supply them, and in what amount. The supply is directly dependent on the demand for a particular product in a particular area, so how much is demanded that much is supplied.

what is one effect of convection currents in the mantle
Explanation:
[tex]\huge{\underbrace{\overbrace{\mathfrak{\pink{Answer:}}}}}[/tex]
Convection currents within the mantle provide one potential driving force for plate movement. The plastic movement of the mantle material moves like the flow of mountain glaciers, carrying the lithospheric plates along as the convection movement in the mantle moves the asthenosphere.
It is believed that the activity of tectonic plates in the crust is fueled by these currents. The plates floating on top of the mantle's moving magma are carried by this movement. Convection causes the continuous creation and destruction of the Earth's crust.
What is the cause and effect of mantle convection?Thermal convection in the rocky layer between the crust and core of the terrestrial planets, where hot material rises and cold stuff sinks, controls plate tectonics, volcanic activity, chemical segregation, and global cooling.
Particles of a fluid or gas are frequently transported from one location to another by convection currents. These are produced as a result of variations in a particular gas or fluid's temperature and density. Convection is one of three different ways that heat is transferred, the other two being radiation and conduction.

Use this picture to apply your knowledge of ecosystems and communities to compare and contrast the ecosystem and community in which an American black bear lives and interacts.
Bears, an important part of ecosystem, have their biome in places likes forests, mountains, tundra, deserts, and grasslands.
What kind of ecosystem does the bear live?
Bears are a small group of mostly large omnivorous mammals that live all over the world in forests, mountains, tundra, deserts, and grasslands. American black bears are only found in North America, while spectacled bears are only found in South America.
Asiatic black bears can be found throughout Asia. The sloth bear is also found in Asia, most notably in India, Nepal, Bhutan, and Sri Lanka, but it is thought to have vanished from Bangladesh. Polar bears and giant pandas are among the most endangered bear species. Polar bears can only be found in the icy lands of the Arctic, and pandas can only be found in the wet and cool bamboo forests of central Asia.
About their interaction in their biome, they are relatively quiet creatures but they will occasionally make sounds to communicate. They cubs bawl and moan when distressed, and suckling produces a grunting purr sound. The females communicate with their cubs by grunting or moaning in order to send them up trees for safety or to have them follow her.

Black bears are opportunistic omnivores, meaning they feed on a wide variety of plants and animals.
What are black bears about?The American black bear (Ursus americanus) is found throughout North America, from Canada to Mexico, and from the Atlantic to the Pacific coasts. The species is found in a wide variety of habitats, including forests, mountains, and wetlands
In terms of ecosystem, black bears are opportunistic omnivores, meaning they feed on a wide variety of plants and animals. They primarily eat fruits, berries, nuts, insects, and other small animals such as rodents. They also consume fish and carrion when available. They play an important role as seed dispersers for many plant species and are also important for maintaining the health of many ecosystem by controlling the population of small mammals.
Black bears are solitary animals, and they do not form complex social groups like many other mammals. They primarily interact with other bears during the mating season, and otherwise they tend to avoid one another.

Answer:
X = 22°
Y = 50°
Z = 108°
Explanation:
Given :
From the diagram shown :
The diagram shows a parallelogram with sides of parallel and equal length.
Z = 108° (opposite angles are congruent)
X = 22° (Alternate angles)
To get Y:
108° + 22° + y = 180° (sum of angles in a triangle)
130° + y = 180°
y = 180° - 130°
y = 50°
Hence,
X = 22°
Y = 50°
Z = 108°

Air pressure is greatest ____ because there are more molecules of air pushing down from above. a. at the top of the mountain c. in the troposphere b. at sea level d. in the exosphere
Answer:
The answer is B, at sea level.
Explanation:
Air pressure is greatest at sea level because there are more molecules of air pushing down from above. Thus, option 'B' is the correct option.
Where the air pressure is the greatest?The lowest point in the atmosphere has the highest atmospheric pressure. Additionally, here is where the air is densest. As one ascends higher in the atmosphere, pressure and density drop. The mass of the atmosphere is drawn toward the surface of the earth by its gravitational field.
In actuality, 99.99997% of the atmosphere's bulk is contained within 100 kilometers of the earth's surface, whereas 90% of the atmosphere's mass is contained within 16 kilometers (Lutgens 17). The typical free route between air molecules is approximately 10 km at 600 km (Lutgens 18). From this point on, the atmosphere keeps getting thinner with height until it eventually combines with space itself.
