B.) Members of different ethnic groups do not communicate.
C.) Those of different ethnic groups must find an interpreter.
D.) Most people of these regions have the ability to speak several languages.
Answer:
D.) Most people of these regions have the ability to speak several languages.
Explanation:
With 54 countries, African linguistic diversity is impressive. Currently, Africa has 2092 languages spoken, which is no less than 30% of the languages on the planet. In addition to the two thousand languages, there are another eight thousand dialects. Thus, multilingualism is the main characteristic of the continent. The presence of innumerable variants sharing the same living spaces end up providing unique and complex ways of seeing and interpreting the world.
Identify what igneous rock is primarily dependent on for its chemical composition
A wind that blows from the southwest across the indian ocean toward south asia from june through september is a _____.
The gas that is the largest component of the atmosphere is _____.
a. water vapor
b. oxygen
c. carbon dioxide
d. nitrogen
e. argon
The gas that is the largest component of the atmosphere is oxygen. The correct option is B. In nature, nitrogen (N2), which accounts for about 78% of air, is the most prevalent gas. The second most prevalent gas after nitrogen (N2) is oxygen (O2).
Which gases are most important?One of the most crucial gases to humans is oxygen. Due to the necessity of carbon dioxide for photosynthesis in plants, it is one of the most vital gases for all life on Earth.
The other main factor is that, in contrast to oxygen, nitrogen is much more stable in the atmosphere and plays a much smaller role in chemical reactions that take place there. As a result, it has accumulated in the atmosphere to a much greater extent than oxygen over geological time.
Thus, the ideal selection is option B.

What is the very large depression at the top of some volcanoes called?
Answer:
Caldera
Explanation:
A caldera is defined as a prominent geological feature that is a very large type of depression, which forms right after the eruption of a volcano. The caldera has a diameter of about 1 km and the all the pyroclastic materials, volcanic ashes, blocks and lapillies and harmful gases are ejected through this caldera. As the rocks of the apical portion melts and collapses, the caldera gets is circular shape.
In what way are volcanic eruptions and meteoric impacts similar?
A.Both can cause global cooling.
B.Both can cause global warming.
C.Both emit oxygen gas into the atmosphere.
D.Both have a greater effect on weather than on climate.
Answer:
A.Both can cause global cooling.
Explanation:
According to researchers, the impact of an asteroid and volcanic eruptions probably covered the planet with harmful dust and gases, which could change the climate and caused the early extinction of many species.
Life on earth would take thousands of years to recover from the devastation.
"The scenario we suggested, that the impact of the asteroid would cause volcanism, reconciles with the facts we once thought was an unbelievable coincidence," said Mark Richards of the University of California at Berkeley.
The length of time that a volcanic eruption impacts the climate is largely determined by
Answer:
The length of time that a volcanic eruption impacts the climate is largely determined by whether the ash or gas reaches the stratosphere
Explanation:
A volcanic eruption releases gases and other particles in the atmosphere. The factor whether these released material reaches the stratosphere or not, determines whether that particular volcanic eruption will affect the climate or not.
The enormous output from the eruption gets released in the atmosphere. This output forms a permanent layer in the atmosphere over time and becomes a barrier to the sunlight reaching the earth.
The decrease in sunlight causes cooling effect thereby decreasing the temperature of the planet.
The time taken by the emission to reach the stratosphere determines the time taken by the emission to change the climate of the planet.

Weather-station measurements indicate that the dewpoint temperature and air temperature are getting farther apart and that air pressure is rising.which type of weather is most likely arriving at the station?
The weather station measurements indicating that the dewpoint temperature and air temperature are getting farther apart, combined with the rising air pressure, suggest that clear and more settled weather is likely arriving at the station.
The dewpoint temperature is the temperature at which air becomes saturated with moisture and dew can form. When the dewpoint and air temperatures are close together, it implies higher relative humidity, often associated with cloudier skies and potential precipitation. Conversely, when the dewpoint and air temperatures are farther apart, it usually signifies lower humidity and clearer skies. Rising air pressure typically indicates the approach of a high-pressure system, which is commonly linked to fair weather conditions. This transition can lead to sunny skies and less precipitation. Weather forecasting involves complex variables, but these signs—increasing gap between dewpoint and air temperatures alongside rising pressure—are classical indicators of improving weather conditions.

why is russia officially call the russian federation
Answer:
Russia is officially called the Russian Federation (RF) because it is constituted of about 85 federal constituent units.
Explanation:
A federation is basically a larger government made up of many other smaller governing units of principalities. The country of Russia is divided into '85 such federal units' which are administered by their own local governing bodies. These local governing bodies are accountable to the central government of Russia. The central government performs supervision over the smaller federal units and is the supreme parent authority.when did the cambrian explosion occur

Strike is a way of representing the 3D orientation of a planar surface on a 2D map. Fault can be characterized by brittle deformation in rocks. These faults can be oriented at any direction (Strike). Shear stresses can produce faults where movement can occur in strike direction.
Answer:
The statement that says 'on a geologic map, strike represents the directional orientation of a fault' is false.
Explanation:
If it is considered that the given geologic map is of a horizontal plane, then the 'direction of the rock' present on this horizontal plane would be represented by a strike on the given geologic map. To represent a fault on the 'geologic map', the symbol of a thick line inclined towards the right is used.What factor has prevented ,Myanmar's economic development?
what kind of fossil aging is used when scientists use the law of superposition?
Answer:
When scientists use the law of superposition, the type of fossil aging they use is known as relative aging.
Explanation:
Scientists use different methods of aging to determine the 'age of rock fossils'. One of these techniques is that of relative aging. In this technique, the scientists 'determine the age of the bottom-most rock fossil' first and go by the principle that every new layer of rock superpositioned above the lower rock is comparatively younger than the lower rock.What are the large and small magellanic clouds, and the sagittarius and canis major dwarfs?
