Question 7
Imagine a scientist is conducting an experiment on the effects of acid on weathering rocks. In this experiment, there
are three different samples of identical rock pieces. The scientist does not add anything to the first sample. The
scientist adds 5 drops of acid the second rock and 10 drops of acid to the third rock. What is the dependent
variable?
a. Amount of weatering
b. Amount of Acid
C. Amount of rain
d. Number of Rocks
Answer:
a. Amount of weathering
Explanation:
In this experimental setup, the amount of weathering is the dependent variable. It is that variable that depends on the action of another.
The dependent variable usually surfaces as the one being tested for. The independent variable does not rely on anything. It is usually the cause of the phenomenon observed in the experimental procedure.In this case, the amount of acid is the independent variable.
The dependent variable is the amount of weathering.

Answer:
When a fossil disappears from the fossil record, we know that those organisms went extinct.
Explanation:
The first option is not correct because there simply isn't any proof of alien abductions, nor that they have visited our planet.
The second option is correct because when a fossil that has been present in particular geological layers suddenly is missing, usually means that the organism went extinct at that time or very soon after.
The third option is not correct because the fossils are proof of the existence of the organism.
The fourth option is not correct because one of the options above is correct.

Studies have shown that there is a relationship between the type and location of boundaries and the distribution and depth of earthquakes along or near these boundaries. Many earthquakes, shown in the map as wide bands, occur along convergent areas. These areas experience varying depths of earthquakes. Where would oceanic-oceanic convergence most likely occur? Nazca plate converging with the South America plate, forming the Andes mountains Philippine plate converging with the Pacific plate, forming Mariana Islands in the Pacific Ocean Juan de Fuca converging with the North American plate, forming the Cascade mountains North America Plate converging with the Eurasian Plate, forming a mid-ocean ridge
Answer:
Philippine plate converging with the Pacific plate, forming Mariana Islands in the Pacific Ocean
Explanation:
Oceanic convergence is the process resulting from the impact generated by the collision of two oceanic plates. This impact causes the heavier plate to sink to the point of being below the less heavy plate. The stronger the impact, the lower the heavier ocean plate will descend and the further it descends, the more it will be heated by the earth's mantle. As this plate is heated, the materials that melt and are incorporated into the mantle that increases in volume to the point of creating cracks in the terrestrial surface. This is how volcanic islands are formed, as well as cracks, similar to trenches on the seabed, are also created. Most of these volcanic islands are located in the Pacific, in the most easterly region. A strong example of this type of phenomenon is the Mariana Islands in the Pacific Ocean.
Answer:
B) Philippine plate converging with the Pacific plate, forming Mariana Islands in the Pacific Ocean

What are some of the unique ways Caribbean islands formed?

As Most of us know, the majority of the Caribbean Islands were formed by volcanic and tectonic plate activity. Tectonic plates wrestled and moved against each other to force one plate towards the ocean's surface to create new Islands.
Answer:
not sure if this is unique but here are some ways they are formed by volcanic and tectonic plate activity.
Explanation:
The iron and nickel in the inner core are hotter than the surface of the sun. It is hot that it should liquid. Why isn’t it?
Answer:
Iron and nickel are heavy materials but the reason they stay solid in the Earth's core where temperatures can reach 5,427 C is because of the very intense pressure in the core to the point that all the metals are extremely cramped up together that prevents them from melting
Explanation:
What if the United States, Mexico, and Canada took the EU's example and joined to form a North American Union? Based on your knowledge of the European Union, describe two setbacks or hurdles that this idea might face.
Answer:
If a North American Union was created, the biggest problems that would occur would be rapid population shifts, and lower wages because of much-increased competition on the labor market.
Explanation:
A North American Union, by EU's example, would mean that the US, Canada, and Mexico will function as one in many ways. The borders will be open, both for economic actions and for free movement of people. While this may seem good at first sight, it will actually cause some major problems as well.
The US and Canada will face a major population increase in a very short period of time. The people from Mexico will rush to move into these two countries because of better living conditions and more job opportunities, which in turn will cause massive depopulation in Mexico.
On one side, Mexico will face major economic problems because of a sharp decline in its labor force, while on another side, the people in the US and Canada will face problems because there will be tens of millions of new laborers that will offer their services for lower wages. This will lead to tens of millions of people losing their jobs or not being able to find jobs, or if they do, they will have to work for less, meaning that they will be poorer.

How is Vladimir Putin's presidency similar to that of the communist leaders of the Soviet Union
Answer:
His presidency is similar in a sense of dominant role that he has in the country, but also in the countries in the region, but also because of his attitude towards the Western countries.

Compare and contrast 2D and 3D maps
PLEASE I NEED HELP ITS DUE AT 8 AM !!
Answer:
Alright.
Explanation:
'2D and 3D refer to the actual dimensions in a computer workspace. 2D is "flat", using the horizontal and vertical (X and Y) dimensions, the image has only two dimensions and if turned to the side becomes a line. 3D adds the depth (Z) dimension.'
Basically, 2D maps are flat (like paper), and 3D maps are not (like a globe).

What did rivers contribute to the development of early civilizations?
a.fertile land, irrigation, and transportation
b.fertile land, bathing area, and livestock supply
c.irrigation, trade, and defense against invaders
d.none of the above
Answer:
Correct answer is a. fertile land, irrigation, and transportation .
Explanation:
A is the correct answer as around great rivers such as Tigris, Euphrates, Nile, Indus and many others civilization emerged due to fertile land that was created during the period when the rivers would overflow the land.
In addition to that they have improved irrigational system, so they could develop agriculture as a main labor during that period which brought them necessary crops.
Rivers were main way of transportation, which can be seen from many sources about Nile or Tigris.
All other answers are thus wrong.

Find the midpoint between (0,0) and (-4,-12)
(29) and (5,1)
Answer:
-2, -6
[tex]\frac{7}{2}[/tex] , 5
Explanation:
Given coordinates;
(0,0) and (-4,-12)
(2, 9) and (5,1)
Unknown:
Midpoints of the coordinates = ?
Solution:
The coordinates of the midpoint are given as;
x[tex]_{m}[/tex] , y[tex]_{m}[/tex] =( [tex]\frac{x_{1} + x_{2} }{2}[/tex] , [tex]\frac{y_{1} + y_{2} }{2}[/tex])
Now;
x₁= 0 x₂ = -4 y₁ = 0 y₂ = -12
Input the parameters and solve;
x[tex]_{m}[/tex], y[tex]_{m}[/tex] = [tex]\frac{0+(-4)}{2}[/tex] , [tex]\frac{0+ (-12)}{2}[/tex] = -2, -6
For (2, 9) and (5,1)
x₁= 2 x₂ = 5 y₁ = 9 y₂ = 1
x[tex]_{m}[/tex], y[tex]_{m}[/tex] = [tex]\frac{2 + 5}{2}[/tex] , [tex]\frac{9 + 1}{2}[/tex] = [tex]\frac{7}{2}[/tex] , 5
