Both longitude and latitude are angles measured with the center of the earth as an origin. A longitude is an angle from the prime merdian, measured to the east (longitudes to the west are negative). Latitudes measure an angle up from the equator (latitudes to the south are negative).
Answer:
The astenosphere is located below the lithosphere
The mantle is composed of silicate material
Explanation:
The Earth has several different layers, and they can be presented in two different manners, depending on their chemical composition and their physical properties. According to the chemical composition the Earth has three layers, crust, mantle, and core, while in accordance to the physical properties it has five, lithosphere, astenosphere, mesosphere, outer core, and inner core.
The astenosphere is the second layer from the top, and it lies just below the lithosphere. It is also the upper part of the mantle. The mantle is a layer that is largely composed of silicate material, mostly silicate molten rock. It can easily be seen from the volcanic activities that this layer is composed of silicate material because the magma is rich in it, and the magma comes from this layer.

Answer:
In my opinion, if the United States were not a set of unified states under a single national government but rather a set of independent nations without ties to each other, the quality of life of the inhabitants of each independent state would drop considerably. This is so because the economies of each state would be significantly less decisive than the American economy in general, and except for specific cases such as California, Texas or New York, the rest of the states would have a notable lack of resources that should be compensated through unfavorable trade treaties with other countries. In addition, the demographic and political weight of each state would be much smaller, which would not be able to obtain the same commercial benefits that are obtained today, which would generate a greater lack of jobs and a decrease in the quality of life of the citizens.
