Dialects are the variations of one language usually differentiated by the regions. Different dialects are part of the same language and most likely all the speakers of the language will understand each other.

Write a paragraph describing the location of the major population centers in Egypt. Make note of their proximity to physical features or other natural resources. What characteristics do these locations have in common?

Answers

Answer:

Egypt's population is highly concentrated along the Mediterranean coastline and along the Nile River.

Explanation:

Egypt is a country that has a relatively high population which is also constantly growing. When looking at the dispersal of the population in the country it is very easy to notice that it is highly concentrated in two areas while the rest of the country has very little to no population. The two areas where almost all of the population is concentrated are the Mediterranean coastline and the Nile River Valley.

The reason why the population is concentrated in these two areas is that these are the only two areas that actually provide suitable living conditions. The Mediterranean coastline has the best climate conditions in the country and the access to the sea and closeness of large economies nearby makes it easier for people to be provided with what they need. The Nile River is the only river in Egypt and its valley is the only one that provides fertile soil for agriculture, so naturally, people have settled here because it is the only area that enables the production of food and has access to water. The rest of the country is a very hot and very dry desert without water sources.

Answers

Answer:

subsistence farming

Explanation:

Agriculture and farming and the major point of Bolivia’s economic processes. Almost half of the people in Bolivia work in agriculture.

Some of the main products that Bolivia gains from farming are potatoes, maize, sugarcane, cocoa, banana, soy, tangerines, beans, cotton, and oranges.

Much of the agriculture is turned towards subsistence farming. This means that crops and livestock are grown for personal use and survival. In the mid-90s, almost 40% of farming was done for personal use.

Recently, Bolivia tried to help this idea by supporting and favoring the small producers in order to make more goods get to the market and help the economy.

2. Explain why 'recycling' is used to describe

the process of the tectonic plates.

Answers

Answer:

We use the word recycling to describe the tectonic plates process because when tectonic plates collide, parts of the continental crust goes back to the mantle.

Explanation:

When tectonic plates collide, subduction takes place. As a result, one tectonic plate with low density slides over the other with a higher density. As a consequence, parts of the plate with higher density goes back into the Earth's mantle. There, it melts and creates new crust when the seafloor expands. We can see that there is recycling in the tectonic plates process since there is a reuse of lithosphere's parts.

What is it called when water vapor up in

Answers

Answer:

precipitation

Explanation:

I did the Edpuzzle, 2021

Precipitation is called when water vapour up in the sky becomes liquid water.

What is meant by precipitation?

Water that falls to the ground can take the form of hail, mist, rain, sleet, or snow. There are many different types of precipitation, such as rain, snow, hail, and sleet, but they all share several traits. They all come from clouds. They are all different types of water that fall from the sky.

Precipitation happens when the water condenses and "precipitates" or falls when an area of the atmosphere reaches 100% relative humidity, or saturation with water vapour.

The term "rain" refers to precipitation that contains water. When the temperature falls below 0 degrees Celsius, precipitation that appears as tiny snowflakes is referred to as snowfall.

Thus, it is precipitation.

Write a report on Russia. What do you think about this country? Would you like to go there? Describe the sights of the country.​

Answers

Answer:

Russia, the largest country in the world, occupies one-tenth of all the land on Earth. It spans 11 time zones across two continents (Europe and Asia) and has coasts on three oceans (the Atlantic, Pacific, and Arctic).

There are about 120 ethnic groups in Russia who speak more than a hundred languages. Roughly 80 percent of Russians trace their ancestry to the Slavs who settled in the country 1,500 years ago. Other major groups include Tatars, who came with the Mongol invaders, and Ukrainians.

Russia is known all over the world for its thinkers and artists, including writers like Leo Tolstoy and Fyodor Dostoevsky, composers such as Pyotr Ilyich Tchaikovsky, and ballet dancers including Rudolf Nureyev.

Russia's history as a democracy is short. The country's first election, in 1917, was quickly reversed by the Bolsheviks, and it wasn't until the 1991 election of Boris Yeltsin that democracy took hold.

Russia is a federation of 86 republics, provinces, territories, and districts, all controlled by the government in Moscow. The head of state is a president elected by the people. The economy is based on a vast supply of natural resources, including oil, coal, iron ore, gold, and aluminum.

The earliest human settlements in Russia arose around A.D. 500, as Scandinavians moved south to areas around the upper Volga River. These settlers mixed with Slavs from the west and built a fortress that would eventually become the Ukrainian city of Kiev.

Kiev evolved into an empire that ruled most of European Russia for 200 years, then broke up into Ukraine, Belarus, and Muscovy. Muscovy's capital, Moscow, remained a small trading post until the 13th century, when Mongol invasions in the south drove people to settle in Moscow.

Explanation:

Answer:

Russia is the largest countries in the world. Most of its part lies in Asia, but the largest part of population lies in Europe. Population is mostly consisted out of Russians, but there are also many minorities. They are mostly Orthodox Christians.

As a vast land Russia covers many region, including the region of Siberia, which I would like to visit. That vast region is practically always covered with ice and snow, but the nature is unbelievable. You can see different animals, different landscapes. In one moment you can be on the Baltic Sea and in the other on the Sea of Okhotsk. I would really like to visit it.

Explanation:

Russia has an interesting history. Since the 17th century they were major force. They fought with Napoleon, Hitler and many others. Writers like Tolstoy and Dostoyevsky are born there.

Cities such as Moscow and St. Petersburg are amazing and everyone should visit them.

He was another important figure in the Enlightenment. In his writings, he discussed the separation of government powers into an executive, legislative and judicial branch. He was inspired by the British system, but he imagined a system even better where no one person or branch could have all the power.The reason behind the separation of power was that a person or group of people who gain too much power can start making decisions that don't benefit all of society. They can use the government to benefit themselves or their friends instead. One way of keeping this in check is by separating powers in the government. Different responsibilities fall to different branches of government. This keeps any one branch from having too much power. One branch of government may promote a bad idea. But hopefully, the other branches will limit their power.Which detail from the passage best explains why Montesquieu argued for the separation of government powers?A.
