What is a population pyramind?

Answers

Answer:

The population pyramid is a graphical depiction of age and sex structure of population in a certain region ( usually state).

Explanation:

Pyramid is not the most adequate term since it`s two-dimensional and has a shape of a triangle. Left side of this triangle represents males and the right side females. This pyramid is presented with a set of bars which are pilled one on another. The bars are longer on the base and shorter on the top, hence the shape of a triangle. Each bar represents a certain age range. The lowest bar represents the range from 0 to 4 years. The one above from 5 to 9 years, the next from 10 to 14 years and so on. The length of a bar represents the number or the percentage of that range in the given population.

The pyramid population is regarded as one of the best ways to visualize age structure in both sexes.

Into which layer of the Earth do plate boundaries extend?
A.outer core

B.lithosphere

C.lower mantle

D.asthenosphere

Answers

Answer:

B.lithosphere

Explanation:

Earth’s crust is made up of tectonic plates and the upper part of the mantle layer underneath. Together the crust and upper mantle are called the lithosphere and they extend about 80 km deep.

Answer:

The correct answer is B. Plate boundaries extend into the lithosphere.

Explanation:

A tectonic plate or lithospheric plate is a fragment of the lithosphere which results from its cutting in the manner of a puzzle by a system of faults, ridges, rifts and subduction trenches. The lithospheric plates move a few centimeters a year in different directions, resulting in the formation of areas of divergence, subduction, collision and sliding.

Plate tectonics is the theory that explains the structure and dynamics of the Earth's surface. It states that the lithosphere, the coldest, stiffest upper portion of the Earth, is fragmented into a series of plates moving over the Earth's mantle. This theory also describes the movement of the plates, their directions and interactions. The Earth's lithosphere is divided into 7 large plates and several smaller plates or microplates. At the edges of the plates seismic, volcanic and tectonic activity are concentrated. This results in the formation of large chains and basins.

Answers

The given scenario is Centrifugal .

Explanation:

Centripetal force means the "force required in order to keep an object moving in a curved direction towards the rotating core," whereas centrifugal force is defined as "an appearing force felt by an object to move on a curved route which acts outside the center of rotation

Newton's laws of motion define this obvious external force. The first law of Newton states that "the rest of the body shall be resting and the heart's movement shall continue unless it is carried out by external forces."

For example, an evaluation of the material motion in a flight airliner can be done on the aircraft, on the earth's layer and even on the Sun.

2. June 21 - September 23 Experiencing Summer

3. September 23 - December 22 Experiencing Autumn

4. December 22 - March 21 Experiencing Winter

Explanation:

The change of seasons on earth is influenced by the earth's revolution towards the sun. The earth's tilted position of 23 1/2 degrees results in a time when the northern hemisphere receives more sun and less southern earth, and there is when the southern hemisphere receives more sunlight and the southern earth more. During 365,2563666 Earth days circling the sun, there were 4 main seasons in both the Southern Hemisphere and the Northern Hemisphere, which occurred alternately. The four seasons include summer (Summer), autumn (Autumn), spring (Spring), and winter (Winter). When viewed from the north pole, the sun becomes a Sumpumpolar star from March 21 to September 23, because during those 6 months the sun never sets. After September 23, the sun is below the horizon and never seen again. This lasts until March 21 or for 6 months. However, the night is not until 6 months (183 days), but less than 179 days it is caused by the influence of fog.

Why is difficult to forward a single and uniform meaning to the term geography​

Answers

Answer:

The discipline of geography encompasses a broad range of approaches to the interrelationship between human activity and the physical features of the earth.

Explanation:

The academic scope of geography is very broad because there are multiple ways that we interact with our physical environments and thus there are many subjects that fall under the disciplinary boundaries of geography. There are two major subfields: Physical geography and human geography. The focus in physical geography is generally more akin to the natural sciences, and human geography is more like the social sciences.  These two subfields can have radically different emphasis and research design and this contributes to the difficulties in giving geography a single or uniform meaning.  

all the water on earth today is

Answers

Final answer:

Despite Earth's abundance of water, only 4 percent is freshwater, of which 68 percent is in glaciers, making it inaccessible. Less than 1% of Earth's freshwater is available for human consumption, leading to critical shortages as demand from a growing population increases.

Explanation:

The question of why access to drinking water is critical despite the large quantities of water on Earth can be addressed by understanding the distribution of water types on the planet. The correct answer to the provided multiple-choice question is option c. Only 4 percent of the total water on earth is freshwater, out of which 68 percent is found in glaciers. While the Earth's surface is covered by about 71% water, about 97% of this is saline water in the oceans. Freshwater represents only 2.5% of the total water, most of which is locked in ice sheets, icebergs, and glaciers. Consequently, less than 1% of freshwater is readily accessible as surface water for consumption by living organisms, including humans.

This scarcity of accessible freshwater is compounded by the increasing demands of a growing global population, where water usage has multiplied sixfold over the past century. Predictions indicate that by 2025, only half of the world's population will have sufficient access to clean water.

Protecting and efficiently managing our freshwater resources is crucial due to the limited availability of water that is suitable for human consumption without further treatment—such as desalination or rainwater harvesting. This situation underscores the importance of water conservation and finding sustainable methods to fulfill the water needs of communities worldwide.

Triangle A B C. The measure of angle A is fifty five degrees, the measure of angle B is eighty degrees and the measure of angle C is x.

Answers

Answer:

C=45 degrees

Explanation:

Important thing to know about triangles is that the sum of its angles is always 180 degrees, so whether it is equilateral, isosceles, scalene or right triangle they`re angles always sum up to 180 degrees. We can express that by an equation: A + B+ C = 180 degrees. So, in this case we have 55 + 80 + C = 180 degrees.  Now we can calculate the value of the angle C.

C= 180-(55+80)

C= 180 - 135

C= 45 degrees

So the x, or in this case the angle C is 45 degrees.

Choose two parts of the earth system and give an example of how they interact to affect weather

Answers

Humans (biosphere) built a dam out of rock materials (geosphere).
Water in the lake (hydrosphere) seeps into the cliff walls behind the dam, becoming groundwater (geosphere), or evaporating into the air (atmosphere).

Final answer:

The interaction of the atmosphere and hydrosphere through the water cycle and the interaction between the atmosphere and lithosphere through orographic lift are two examples of how different parts of Earth's system influence weather.

Explanation:

To illustrate how two parts of the Earth system interact to affect weather, let's consider the atmosphere and the hydrosphere. An example of this interaction is the water cycle, where the Sun heats water in oceans, rivers, and lakes, causing it to evaporate and form water vapor in the atmosphere. This water vapor condenses into clouds and eventually falls as precipitation, which can be rain or snow depending on the temperature. This interaction affects weather patterns, such as the distribution and intensity of rainfall.

Another example involves the interaction between the atmosphere and the lithosphere (Earth's crust). When air masses move over mountain ranges, they are forced to rise, cool, and condense, often leading to precipitation on the windward side of the mountains, a process known as orographic lift. This interaction influences local weather, creating wetter climates on windward slopes and drier conditions on the leeward, the rain shadow effect.

Answer:

Explanation:

The Americas were located across the Atlantic Ocean from Africa, the place of origin of the human species. When humans began migrated out of Africa, they did so following the easiest land routes. As such, humans arrived to China and Europe much sooner than they arrived in America.

It has been speculated that humans first arrived in the Americas from Asia. This is presumed to have occurred by crossing the Bering Land Bridge or, possibly, the Pacific in boats from Polynesia.

Even during the European Age of Exploration, sailing across the oceans was a massive feat, and no one really new what awaited hapless mariners on the other side. When they arrived, they found lands that were settled, but they were not the islands they had been looking for.

The Moon, the Sun, and Earth form a straight line during the new Moon and full Moon.

Answers

Answer:

The Moon, the Sun, and Earth form a straight line during the new Moon and full Moon.

Explanation:

When the earth, moon, and sun line up- which happens at times of full moon or new moon- the lunar and solar tides reinforce each other, leading to more extreme tides, called spring tides.

Final answer:

Strong tides occur during the new and full Moon because the Moon, Sun, and Earth align, creating spring tides. In contrast, neap tides with lower high tides occur when the Sun and Moon are at right angles to each other.

Explanation:

There are very strong tides during the new Moon and the full Moon because during these phases, the Moon, the Sun, and Earth form a straight line. This alignment is known as a syzygy and it happens during both the new Moon and full Moon phases. When this occurs, the tidal effects from the Sun and Moon combine to produce the highest tides, known as spring tides. Conversely, when the Sun and Moon are at a 90° angle relative to Earth during the first and last quarter Moon phases, the tidal effects are not as aligned and partially cancel each other out, resulting in the lowest tides, called neap tides.
