Explanation:

Rocks and minerals are all around us! They help us to develop new technologies and are used in our everyday lives. Our use of rocks and minerals includes as building material, cosmetics, cars, roads, and appliances. In order maintain a healthy lifestyle and strengthen the body, humans need to consume minerals daily. Rocks and minerals play a valuable role in natural systems such as providing habitat like the cliffs at Grand Canyon National Park where endangered condors nest, or provide soil nutrients in Redwood where the tallest trees in the world grow.

Rocks and minerals are important for learning about earth materials, structure, and systems. Studying these natural objects incorporates an understanding of earth science, chemistry, physics, and math. The learner can walk away with an understanding of crystal geometry, the ability to visualize 3-D objects, or knowing rates of crystallization.

Natural objects, such as rocks and minerals, contribute to the beauty and wonderment of the National Parks and should be left, as they were found, so that others can experience a sense of discovery.

The Alps are mountains that serve as a physical boundary between countries in Europe. According the article, the Swiss have created the world’s longest tunnel. How will this new tunnel revolutionize transportation in Europe and overcome this physical barrier?

Answers

Answer:

The Swiss tunnel will contribute to much faster and safer transportation and traveling through the Alps.

Explanation:

The Alps are the biggest natural barrier in Europe. They are the highest mountains, but also the ones that occupy the largest area. All countries that have a part of the Alps and have them as a natural barrier are well-developed countries, but despite this, transportation and traveling are not easy even though the infrastructure is of high quality.

The Swiss have created a tunnel of the highest quality, with very length, and it cuts the distance for transportation and traveling significantly. The sheer fact that the tunnel goes through the mountains and is relatively straight is excellent, and when added to it that all of the curves, change of elevation, slow driving are avoided because of it, just makes even better. By driving through the tunnel there aren't any dangers as on the surface roads, as there isn't snow, ice, and avalanches in it, thus the safety is much higher. The amount of time needed for traveling through the Alps is significantly smaller, so the benefits are huge in the economic sector.

Air pressure has a very strong effect on the weather Which of the following best explains what happens to the air press
A
Colder temperatures cause the air to be more tightly packed which increases the air pressure
As the temperature drops, the air spreads out and takes up more space which decreases the pressure
Cold weather causes Earth to cool, and the heat that leaves Earth pushes against the air and decreases the press
D
When the weather is colder, the clouds weigh more as ice begins to form The heavier clouds increase the air pres

Answers

Answer:

Colder temperatures cause the air to be more tightly packed which increases the air pressure.

Explanation:

The air pressure represents the weight of the air. It is directly dependent on the temperature. The colder the temperature, the heavier and denser the air, the higher the temperature, the lighter and less dense the air. This is simply because of the manner in which the molecules react at different temperatures.

When the temperatures are lower, the molecules of the air are getting closer to each other, thus the air becomes denser, so in a given area it is heavier and the air pressure is higher. When the temperatures are higher, the molecules spread out, thus they are further away from each other, which in turn makes the air less dense, lighter, so in a given area the air pressure is lower.

C. They are considered centers of art and culture
D. They have never been subjected to warfare or revolution

Answers

Write about art and culture.

The term "art" encompasses a broad range of human pursuits and products that demonstrate technical proficiency, aesthetic beauty, emotional impact, or conceptual depth.

Any human endeavor with a communication or aesthetic goal—one that conveys a thought, an emotion, or more broadly, a worldview—is generally referred to as art. It is a part of the culture, and the design it exhibits is a reflection of the economic and social foundations.

The term "culture" is a general one that refers to social behavior, and institutions, including norms present in human societies as well as the people that make up these groups as well as their knowledge, beliefs, and abilities.

Symbolic frameworks that give meaning to human conduct within such a social or community group are referred to as cultural patterns.

Hence, option C is correct.

Describe the standard of living in North Africa. Be sure to discuss factors such as live expectancy, literacy, and population growth.

Answers

Answer:

The standard of living in North Africa is relatively poor, with life expectancy being below the ones of the developed countries, literacy rates being low, and high population growth.

Explanation:

North Africa, as the name suggests, is a region located in the northern part of the African continent. It is a region dominated by desert landscape, lack of freshwater reserves, and lack of arable land. The population is highly on very small areas, while most of the territory lacks human presence. This region had and still has a lot of problems.

Because of the living conditions being generally below par, the life expectancy is not high, close to the global average, but way below the average of the developed countries. The region is dominated by Islam, and as in many Muslim countries, the literacy rates are low because of the limitation of education opportunities for women. The population growth is fast, and with the economies being in bad conditions, it just adds further problems.

Answer:

The standard of living in North Africa is relatively poor, with life expectancy being below the ones of the developed countries, literacy rates being low, and high population growth.

Sovereignty is when *
A government has control over a particular territory
O A government gives up control of territory to another state
O A government uses none of its own natural resources
O A government divides into two territories

Answers

Answer:

A. government has control over a particular territory.

Explanation:

In order to know the answer, it is best to look for context clues in the question.

The word "sovereignty" comes from the root word "sovereign." This word is related to the words: ruler, power, authority, control etc.

Choice A clearly shows the meaning of sovereignty because it emphasizes on the government's authority over a particular territory. It means that it is the supreme ruler.

Choice B doesn't show control because it has given up its authority.

Choice C doesn't show sovereignty because the government doesn't use its natural resources for the betterment of the nation, which is normally being done when one is in control over a territory.

In Choice D, the government is "not in supreme power" because it is divided into two territories.
