Answer:
b. inner core
Explanation:
To solve this problem let's start by listing the information given. This will help us find which option best fits the characteristics provided to find the correct answer.
characteristics of mystery layer:
i. it is solid and extremely hot
ii. it is the innermost layer of the Earth
iii. it is around 800 miles thick
Now let's go through each option to determine which best matches the characteristics.
option a
outer core
The first characteristic of the mystery layer is 'it is solid and extremely hot.' The outer core of the earth, however, is a fluid layer. Therefore, this option cannot be correct.
option b
inner core
The inner core is a solid 'ball' and is about 10,800°F. It is also the inner, or last layer, of the earth and is around 800 miles thick. Therefore, it matches all characteristics of the mystery layer so, this must be the correct answer. If you would like to be sure, I also reviewed the last two options below.
option c
crust
Because the crust is the outermost layer of the planet, it does not match the second characteristic of the mystery layer. Therefore, this cannot be the correct answer to the question.
option d
mantle
Although the mantle does match the first characteristic, it does not match the second characteristic, which requires the layer to be the innermost layer of the earth. The mantle is one of the outer layers of the earth.
Now that all options are reviewed, we have determined the best solution to the problem. The correct answer to this question is b. inner core.
Answer:
inner core
Explanation:
To solve this problem let's start by listing the information given. This will help us find which option best fits the characteristics provided to find the correct answer.

Mineral "A" is a gray metallic mineral with cubic cleavage (3 planes of cleavage at right angles). Its hardness is 2.5; streak is gray to dark gray. Its mass is 29.5 g, and its volume is 3.5 cm3. What is its specific gravity?a) 1.00b) 3.12c) 8.43d) 15.99
Answer:
8.43 ( C )
Explanation:
GIVEN data:
hardness = 2.5
mass = 29.5 g
volume = 3.5 cm^3
specific gravity = density of mineral / density of water
density of mineral = mass / volume = 29.5 / 3.5 = 8.43
density of water = 1
therefore specific gravity of Mineral " A " = 8.43 / 1 = 8.43
Note : The density of the Mineral is the same as the specific gravity of the mineral.

Birds and reptiles are most closely related.
Frogs are more closely related to fish than birds.
Frogs are more closely related to birds than fish.
Fish are the most primitive.
Answer:
The correct options are:
B, C and E.
Explanation:
The cladogram is a diagram which is used to demonstrate the theoretical relationship between groups of animals, called a phylogeny.
Phylogeny examines the relationship between different groups of organisms and their evolutionary development. It tries to trace the evolutionary history of all life on the planet.
Phylogeny stands on the assumption that all organisms share a common origin.
Thus a cladogram is used as a visual aid by a scientist studying phylogenetic relationships to examine the various organisms being and how they relate to each other.

What would happen in a rainforest climate if the orbit around the sun slows down to one orbit per 600days? What would happen in a tundra climate if the orbit around the sun slows down to one orbit per 600days?
Answer:
Both the tundra and the rainforest would cease to exist.
Explanation:
If the earth were limited to an orbit every 600 days, we would have 600 days of uninterrupted sun and 600 days of uninterrupted night, which would cause extremely hot temperatures on one side of the earth, while the other side would face a glacial period. In any case, both the tundra and the rainforest would cease to exist.
The tundra needs lower temperatures to be established. If the tundra were subjected to 600 days of intense, uninterrupted sunshine, it would not be formed and would cease to exist like time.
Similarly, she would die if she were subjected to 600 days of uninterrupted night, because she needs sunlight for plants to grow and perform photosynthesis, which is essential for their survival.

Which activity could best prepare residents along the Mediterranean coast to reduce the loss of human life during a future tsunami?
Answer:
The best thing that inhabitants can do to reduce loss of life during a tsunami is to engage in an evacuation drill in some areas that are particularly vulnerable to earthquakes, and therefore, tsunamis. More specifically, these areas would be low lying neighborhoods that border the coasts.
Geographically speaking, Southern Italy and Greece are the most seismic regions of the Mediterranean, so evacuation drills should ideally be held there.

Melting above a subducting slab produces mafic magma, as described in Exercise 5.10, yet intermediate rocks (andesite, diorite) are common in many subduction zones. Considering the magmatic processes discussed in section 5.4 and the difference between oceanic and continental lithosphere, explain how this intermediate magma forms
Answer:
The intermediate magma has a heterogeneous structure, since it has a part of Silice, approximately 50-60% to be more exact.
When it turns into lava, it produces rocks like the Andesite and, in the opposite case of its crystallization, it forms rocks like the Diorite.
A comparison of felsic magma is much more viscous.
It is important to clarify that this magma is a type of primary magma, that is to say that they are magmas formed from the fusion of the rocks of the mantle or the crust.
Explanation:
The fusion of these rocks are what would give rise to the intermediate magma, this intermediate magma is a primary magma, like the mafic and felsic.
The primary magmas unlike the derived magmas is the origin or the reason for how they are formed, which is what we write above, derived magmas usually form differently since they are the product of the evolution or changes that magmas undergo primary

Environmental problems need global intervention. Explain briefly
Answer:
(This is only very brief)
Environmental issues are created by the earth as a whole which includes all the countries within it therefore making environmental issues global issues. No country alone has caused global warming. This also means that no country alone is able to single-handedly defeat an environmental issues which have now spiralled out of control. No one has enough resources, that's why it would be better if there was a global intervention for environmental issues because the more brain power and resources, the better.
Find the equation of the line that is parallel to y=2x and goes through the point (-2, 3 )
Answer:
y=2x+7
Explanation:
Y=mx+b
y=2x has a rise of 2 and a run of 1 ( goes up two and over one)
to find use the change in slope formula (y2-y1)/(x2-x1) that are on the line
I used (0,0), (1,2)
(2-0)/(1-0)
2/1
your change in slope is 2
To find the y-intercept which is b you have to enter the point (-2,3) into the original equation
y=2x+b
3=2(-2)+b
3=-4+b
3+4=b
7=b
therefore your final equation is y=2x+7
In 1802, when it seemed likely to many scholars that there was life on Mars, the German mathematician Karl Friedrich Gauss proposed that we signal the Martian inhabitants by drawing huge geometric patterns in the snows of Siberia. His plan was never carried out. If his plan had been carried out, which of the following would have been least reasonable regarding the pattern?
a. The patterns should resemble natural formations.
b. They should indicate that they were created by an advanced civilization.
c. The patterns should consist of straight lines and right angles.
d. The patterns should indicate a knowledge of geometry.
Answer:
d. The patterns should indicate a knowledge of geometry.
Explanation:
The German mathematician Karl Friedrich Gauss proposing that we signal the Martian inhabitants by drawing huge geometric patterns in the snows of Siberia and it not being done definitely means that the least reasonable information regarding the pattern will definitely be the patterns indicating a pattern of geometry. This is is because the plan was never carried out.
