Answer:
We study about the sun because
The sun is a normal star. It is much closer to us than any other star, and by studying the sun, we can therefore learn more about other stars. The better we understand other stars, the more we know about the Milky Way. From there we know more about other galaxies and in the end we learn more about the universe.
Explanation:
How does the Sun help to protect life on Earth?
It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze.

Explanation:
What is the stream gradient of GW Creek measured from the point at which it crosses the 20 ft. contour to the point at which the stream is 10 ft above sea level
Answer:
The stream gradient = 5 feet/miles
Explanation:
Steam gradient formula is =
the difference in elevation between two points on the stream over the
distance along the stream which is measured in feet/mile, inch / km etc.
The change in stream elevation- 10 feet.
The stream distance (shown in the map)- 2 miles
Therefore, stream gradient- Change in stream elevation/stream distance
The Stream gradient= 10 feet/ 2miles= 5 feet/miles.

The half-life of Carbon-14 is 5, 730 years. you find a sample where 1.5625% of the original Carbon-14 still remains how old is that sample ?
Answer:
The sample is about 34380 years old.
Explanation:
The amount of Carbon-14 mass diminishes exponentially in time, whose model is described below:
[tex]\frac{m(t)}{m_{o}} = e^{-\frac{t}{\tau} }[/tex] (1)
[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex] (2)
Where:
[tex]m_{o}[/tex] - Initial mass, in grams.
[tex]m(t)[/tex] - Current mass, in grams.
[tex]t[/tex] - Time, in years.
[tex]\tau[/tex] - Time constant, in years.
[tex]t_{1/2}[/tex] - Half-life, in years.
If we know that [tex]\frac{m(t)}{m_{o}} = \frac{1.5625}{100}[/tex] and [tex]t_{1/2} = 5730\,yr[/tex], then the age of the sample is:
[tex]\tau = \frac{5730\,yr}{\ln 2}[/tex]
[tex]\tau = 8266.643\,yr[/tex]
[tex]t = - \tau \cdot \ln \frac{m(t)}{m_{o}}[/tex]
[tex]t = - (8266.643\,yr)\cdot \ln \frac{1.5625}{100}[/tex]
[tex]t \approx 34380.002\,yr[/tex]
The sample is about 34380 years old.

Answer:
With the population moving West, the old Northwest was made up of
d.Ohio, Indiana and Illinois.
Explanation:
Other states that made up the old Northwest were Michigan, Wisconsin, and a portion of Minnesota. New York, Pennsylvania, Cincinnati, and Virginia were never part of the old Northwest. The old Northwest was awarded to the United States after the 1783 revolutionary war. Geographically, the old Northwest included the land between the Great Lakes, the Mississippi River, and the Ohio River.

The correlation between the number of hours Brad studies and the grades he gets is 0.8. Which phrase best describes the correlation between the number of hours Brad studies and the grades he achieves?
Answer: strong positive correlation
Explanation:
A positive correlation exists when the correlation coefficient that we've is greater than 0. This means that both variables that are given move in the same direction.
Since the correlation between the number of hours Brad studies and the grades he gets is 0.8, it means that there's a strong positive correlation due to the fact that the value is close to +1.
This means that the number of hours that Brad studied is a good predictor of
the grade that he gets in his examination but it's not perfect.

In Seoul, Korea it’s said that the air pollution is bad and that it shortens people’s lives by a year or so, would this be true for someone who is going to visit only for three months??
Answer:
yes
Explanation:
I would say it would be true because even though you are visiting for 3 months you will still be breathing the polluted air for the 3 months thus it would affect a person in a negative way and it is true.

Would you expect sediments found in the Cedar Creek alluvial fan to be texturally and compositionally mature, or texturally and compositionally immature
Answer:
I would expect the sediments found in the Cedar Creek alluvial fan to be textually and compositionally immature.
Explanation:
I would expect the sediments found in the Cedar Creek alluvial fan to be textually and compositionally immature because this type of sediment is more common than usual to be present in most alluvial fans. This is probably due to the lack of weathering in these regions, which ends up leaving the sediments little worked, since their structures and compositions are not influenced by weathering factors, with great impact.

In the Layers panel, turn on Borders and Labels and also Gallery > Volcanoes, then double-click on the Problem 7 placemark. Divergent boundaries often begin as triple junctions composed of three rift "arms" at ~120° apart (which may or may not evolve into divergent boundaries). Knowing that rifts (red lines) generally open perpendicular to the rift (or sub-parallel to the light blue transform faults), which of the statements below about this area is incorrect?
a. the NW-trending Red Sea is a linear sea that is opening in a NE-SW direction
b. the ENE-trending Gulf of Aden is a linear sea that is opening in a NNE-SSW direction
c. the volcanoes in Africa define a narrow linear rift that is opening in a NW-SE direction
d. the volcanoes in Africa define a volcanic arc related to subduction off Africa's east coast
Answer:
d. the volcanoes in Africa define a volcanic arc related to subduction off Africa's east coast
Explanation:
Many crust plates move over the mantle. These plates are limited by three types of ridges or borders that differ in the movement they produce.
Boundaries types: Divergent, Convergent, and Transforming.
Divergent boundary: Occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge. New crust is created by the molten materials rising from the mantle. The two plates at each side of the rift separate, and the stream of hot material creates a new seabed between them. It occurs an expansion of the sea bottom, which separates the plates. The divergence direction is transversal to the rift orientation. Old plates get separated, and the new crust instantaneously gets formed. The emerging mantle occupies the space left by the separation of the two plates.
a. the NW-trending Red Sea is a linear sea that is opening in a NE-SW direction. CORRECT → The diverging direction is perpendicular to the rift orientation.
b. the ENE-trending Gulf of Aden is a linear sea that is opening in a NNE-SSW direction. CORRECT
c. the volcanoes in Africa define a narrow linear rift that is opening in a NW-SE direction. CORRECT.
d. the volcanoes in Africa define a volcanic arc related to subduction off Africa's east coast ⇒ INCORRECT. The collision between plates creates volcanic arches and continental arches. This process belongs to the convergent boundaries, in which two oceanic plates collide, or one oceanic plate crushes with a continental one.

Suppose a friend is trying to claim that it is summer when Earth is closest to the Sun and winter when Earth is farthest away. Refute this claim in at least two different ways: (1) with an argument that invokes seasonal differences between the Northern and Southern Hemispheres and (2) with an argument based on the times of year at which Earth actually is closest to and farthest from the Sun. Write out your arguments clearly
Answer:
1) This claim is inaccurate, that there's summer when Earth is closest to the sun and winter when the planet is farthest from the sun.
2) This claim is inaccurate, because Earth is closest to the Sun on January 3-4, when it's Winter in the northern hemisphere and summer in the southern hemisphere. So why it's not Summer in both hemispheres, since the planet is closest to the Sun.
Thus, summer and winter aren't caused by the varying distance between the world and therefore the sun.
Explanation:
1)
If it's so then why seasons are Opposite in two hemispheres. it's summer within the northern hemisphere when it's winter within the southern hemisphere. Alternatively, it's Winter within the northern hemisphere, while it's summer within the southern hemisphere.
If the seasons occurred because of the gap from, sun, then it should be the same season in both the hemispheres, when Earth is farthest and closest from the Sun. Why are seasons different in both hemispheres. So this claim is inaccurate.
2)
Earth is farthest from the Sun on the Fourth of July, which is really summer in the northern hemisphere and winter in the southern hemisphere. So why is it not winter in both the hemispheres, since the planet is Farthest from the Sun.
Here the earth's orbit isn't an ideal circle. it's elliptical, or slightly oval-shaped.
