Ecologists, limnologists, hydrologists, potamologists study the structure, condition, biological and chemical composition of water bodies, watercourses of the planet. If we talk about water arteries, the most full-flowing, deep, long rivers in the world are identified. They are famous for flora, fauna, importance for humans.

Let's talk about the widest river in Russia and in the world, and find out if the channels are suitable for river navigation.

How are rivers divided by width?

The channel of a waterway is formed by the movement of water. The process lasts for centuries, the area of the passage often changes due to natural or environmental reasons. When talking about the width, we mean the maximum distance between two points of different banks, including island areas. The maximum is taken as the basis. The nature of the flow is important ...

About 71% of the surface of the globe is occupied by the waters of the world ocean. It is a single system that interacts with the atmosphere, the Earth's surface. Oceanologists distinguish 5 huge water bodies on Earth, distinguishing their boundaries by continental shores, island groups and clear lines of currents.

The largest ocean in the world is the PacificIt is considered not only the largest by area, but also by depth. Let's talk about its features, characteristics and climate.

Description of the Pacific Ocean

It's hard to say today who discovered the Pacific Ocean. The first Europeans were the Spanish conquistadors who crossed the Isthmus of Panama. It was named by the Portuguese navigator Fernand Magellan, who crossed it in 3 months and 3 weeks without encountering a single storm...

The ancient Romans believed that the destructive fire was commanded by the god Vulcan, hence the name of the geological heights. Today, scientific discoveries have made it possible to describe the origin of volcanoes, the nature of eruptions, the danger to the population living nearby.

Consider the largest active geological hills and give them a description. On the surface of the land their number exceeds 900 units, hundreds more are located under the waters of the oceans.

The largest eruption in history

All terrestrial volcanoes are divided into two types:

• acting;
• extinguished.

Depending on the activity of the eruption, it can last either a few days or indefinitely. It is noteworthy that the atmosphere on planet Earth arose due to the strongest eruptions, during which huge amounts of soot, steam and carbon dioxide were released into the atmosphere.

Travelling from point A to point B can be dangerous if the road is laid out along a difficult section, for example, in the mountains. There are routes in the world where the blood runs cold in the veins of even the most adventurous drivers.

Consider the top most dangerous roads on the planet, find out where they are located, and whether there are ways to bypass the most difficult routes. The quality of the roadbed is also worth paying attention.

Top 10 Most Dangerous Roads in the World

Looking at the roads in the Russian countryside, we want to think that they are the most terrible: knee-deep mud, deep potholes, lack of repair. But there are roads much more dangerous than ours. We present the 10 most dangerous roads in the world, show video of how ...

A city is a large settlement where all sectors of the economy are developed, not just agriculture, as is customary in the countryside or villages. In ancient times, a city was a fortified settlement. With the development of crafts and production, the population of cities is increasing, but some of them have their own history and remain small.

Let's look at the smallest cities in the world in terms of population and area, and talk about their history.

World ranking by size and area

All over the world there are small towns whose development has slowed down. New residents do not come here, the birth rate is not high, and this state of affairs has lasted for decades. In such settlements all residents know each other and, perhaps, ...

Islands, as a rule, we associate with recreation, endless beaches, quiet and carefree. There are also places on the planet where no man has set foot. Uninhabited islands are often those where people can not survive: they have a small area, they have no sources of fresh water.

Consider the smallest islands on earth, tell us where they are located and how people survive on the tiny area.

The Inhabited Islands

An island is a piece of land surrounded on all sides by water. Life on a small plot in the middle of the ocean may seem romantic, but in fact it has a lot of complications:

• hurricane winds, from which it is difficult to hide;
• the emergence of high waves, bringing destruction;
• Lack of fresh water sources;
• difficulties in obtaining food.

The largest water body on the planet Earth is the ocean. Hydrological resources are in constant interaction with the atmosphere and the Earth's surface. Previously, four water bodies were distinguished, which together represented the World Ocean, occupying 71% of the planet's surface. In 2000, the International Hydrographic Organization distinguished the Southern Ocean as a separate body.

Let's look at the list of water areas and find out what the smallest ocean in the world is called.

What are the oceans?

The science of oceanology deals with the study of hydrological processes. The waters of individual water areas have distinctive characteristics, their own unique flora and fauna. The boundaries are determined by currents and the location of the continents.

The Pacific (178.68 million km2)

The largest by area and volume of water in the world, accounting for 53% of the volume of water of the entire world's oceans.Otherwise called ...

Surfing is a unique sport in which a person must curb a big wave. It first appeared in Polynesia and became part of the life of the local people. Europeans also loved surfing, transforming it into other sports (windsurfing, wakesurf). But the main thing remains - a big wave.

Those who want to test their strength in gliding through the water should find a place where the biggest waves meet.

Top 10 places with the biggest waves

The quality of waves in the sea and the ocean is influenced by the strength and direction of the wind. The bottom topography also plays an important role. Surfers all over the world are always looking for the perfect wave: big, high, stable. Let's tell you what points ...

Since ancient times, floating structures have been created by man for various purposes: fishing, travel, transportation of goods, military. These are yachts, ships, tankers, rafts and barges. The most recognizable ship is the giant Titanic, which sank on its first voyage. It was 269.1 meters long.

Некоторые суда имеют огромные размеры, которые позволяют решать сложные задачи. Рассмотрим рейтинг самых больших кораблей в мире на 2023 год, условно разделив их на пассажирские, военные, сухогрузы и танкеры. Это позволит оценить масштабы морских судов, созданных руками человека.

A sea is an isolated part of the ocean, separated by groups of islands, land areas, and currents. There are 73 water areas of this type in the world, not including the lakes that are commonly referred to as the Aral Sea, the Caspian Sea, and others.

Consider the smallest and shallowest seas in the world and in Russia, and find out what their volume, depth, and surface area is.

Washing the shores of Russia

Russia is the largest country in the world, washed by three oceans:

• Tihogo;
• Atlantic;
• Arctic.

Let's find out which of them is recognized as the smallest. Azov Sea - the smallest sea in Russia, which is also the smallest on Earth. Surface area - 39 thousand square kilometers. Refers to the basin of the Atlantic Ocean.
