Earth is placed in one of the spiral hands of the Milky Way (referred to as the Orion Arm) which lies approximately two-thirds of the manner out from the middle of the Galaxy. Hence, Option C is the correct choice.
The Milky Way is the galaxy that consists of our Solar System, with the call describing the galaxy's look from Earth: a hazy band of mild visible withinside the night sky shaped from stars that cannot be in my opinion outstanding via way of means of the bare eye.
The missing information in the question is:
A. It has a central core surrounded by a spherical halo of stars, and
Earth is inside the core.
B. It has a central core surrounded by a spherical halo of stars, and
Earth is in the halo.
C. It has a central core around which its spiral arms spin, and Earth is
in one of those arms.
D. It has a central core around which its spiral arms spin, and Earth is
inside the core.
Hence, Option C is the correct choice that Milky Way Galaxy has a central core around which its spiral arms spin, and Earth is in one of those arms.

The global meteoric water line (GMWL) is a linear relationship that describes the isotopic composition of precipitation (meteoric water) in various regions of the world. It is represented by the equation:
δD = 8 * δ18O + 10
In this equation, δD represents the deuterium excess, and δ18O represents the isotopic composition of oxygen-18 in meteoric water.
Warm and Moist Areas: In warm and moist regions, such as tropical rainforests, you typically find precipitation falling on the lower-left end of the GMWL because both δD and δ18O values are relatively high. The warm temperatures contribute to higher values.
Dry, Colder Areas: Dry and colder regions, like polar areas or high mountainous regions, tend to have precipitation falling on the upper-right end of the GMWL, as both δD and δ18O values are relatively low. The cold temperatures and lower humidity contribute to these lower values.
The GMWL helps scientists understand the sources and processes influencing the isotopic composition of meteoric water in different climatic regions.

B. It allows limited weapons testing of the continent.
C. It limits restrictions of environmental controls.
D. It encourages scientific research.
a. True
b. False
The real answer is True. :) I got it right on a question.
The countryside residents of North Africa and Southeast Asia have multiple reasons for migrating out of the countryside and into the urban areas, most notably:
- Unemployment; people in this parts predominantly are either nomads or subsistence farmers, and they don't really have any options for employment.
- Bad infrastructure; these parts are heavily neglected because they are desertous parts and far from the coastlines, so there's no real interest for this parts by the governments and the infrastructure is on a miserable level.
- Little to no investments; investments in this parts are a relative unknown, there's no interest for this parts because the natural conditions are very bad, there's very few people living in this parts and as stated before the infrastructure is miserable, so no business man is interested to invest and thus help into the development of the region.
- Bad living conditions; the houses are made from natural material that doesn't last long, the landscape is shaped by deserts, the temperatures are extremely high, water and food are scarce...
Explain the reasons that motivate countryside residents of North Africa and Southwest Asia to migrate into urban areas or even out of their countries
1. They are treated well outside of their country
2. They can earn more, pays less tax
3. They can learn more especially for students who wants to enroll outside their country
