Answer:
I would go with A. Salinity and Temperature
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.
The opinion may varies on this question, here are my point of views.
The correct answer would be:
A) spread of innovations
B) cultural blending
C) damage to some cultures
Let's look into them one by one:
A) spread of innovations
- As the technological skills on different areas spread to different countries, people are able to learn and create based on the new knowledge hence enhancing innovations across the world.
(- However,some might held a different opinion as the innovations are concentrated in powerful nations but not the third world countriedls. But what I believe is that under the spread of information, third world countries have chances for innovations as well therefore supporting this claim.)
B) cultural blending
- Under globalization, it is easier for people to travel around the world, bring their own culture and influence to a foreign place, resulting in the blend of culture. For example, you can see many international brands across the globe even in Asia, while you can find China town and production of Asia in places like Europe and America.
C) damage to some cultures
- This is also true. As globalization prevails, some cultures are considered less important as the living mode of people has changed. Languages for example, inder the influence of international language such as English, some minorities dialect are disappearing or the use is decreasing rapidly.
D) increase in death rate
- This is very unlikely to happen. As globalization brings the technology around, the medical advancements are also able to be brought to different place. For instance, the use of xray, or even cancer treatment, are spreaded. This has undoubtedly helped expanding the life span of people.
Therefore the correct answer would be:
A) spread of innovations
B) cultural blending
C) damage to some cultures

Answer:
Rift Valley
Explanation:
I did a quizlet on it LOL
Answer:
An asteroid is in circular orbit around the Sun. Its distance from the Sun is 7.3 times the average distance of Earth from the Sun. The period of this asteroid is C : 20 Earth years .
Explanation:
Kepler's law
T² ∝ R³
T = orbital period of the planet
R = semi major axis of the orbit.
Now
( T₁ / T₂ )² = ( R₁ / R₂ )³
T₁ = Earth time period = 1 year
T₂ = Asteroid time period
R₁ = The distance between Earth and Sun
R₂ = The distance between Asteroid and Sun
From the question ,
R₂ = 7.3 R₁
applying on the above equation ,
( T₁ / T₂ )² = ( R₁ / R₂ )³
( 1 / T₂ )² = ( R₁ / 7.3 R₁ )³
( 1 / T₂ )² = ( 1 / 7.3 )³
T₂ = 19.7 year
Hence ,
approximately T₂ = 20 years.
The period of this asteroid is C : 20 Earth years .
