The greenhouse effect

The greenhouse effect is an increase in the temperature of the earth’s surface due to the heating of the lower atmosphere by the accumulation of greenhouse gases. As a result, air temperature is greater than it should be, and this leads to irreversible consequences such as climate change and global warming. Several centuries ago, this environmental problem existed, but was not so obvious.

Climate of the Urals

The Urals is a geographical region of Russia, the basis of which is the Ural Mountains, and in the south is the river basin of the river. Ural. This geographical area is the natural border of Asia and Europe, east and west. The Urals are roughly divided into the following parts: southern; North average; circumpolar; polar; Mugodzhary; Pai-Hoi.

Moderate and sharply continental climates

Continental climate is a subtype of several climatic zones, which is characteristic of the mainland, remote from the sea and ocean coast. The continental climate occupies the largest territory of the continent of Eurasia and the internal regions of North America. The main natural areas of the continental climate are deserts and steppes.

Climatic zones and zones of Russia

The territory of the Russian Federation is large and located in several climatic zones. The northern coast lies in the climate of arctic deserts. It has a very cold winter, where the temperature reaches -50 degrees Celsius. The weather is mostly cloudy, there is little rainfall, not more than 300 mm per year. Also in this zone, cold Arctic air masses circulate all the time.

Acid Rains: Causes and Consequences

Recently, quite often you can hear that acid rain has begun. It occurs when nature, air and water interact with different pollution. Such precipitation gives rise to a number of negative consequences: diseases in humans; death of agricultural plants; water pollution; forest reduction.

Climatic zones of Australia

Australia is a special continent, on the territory of which there is only one state, called the mainland. Australia is located in the southern hemisphere of the earth. Three climatic zones are pronounced here: tropical, subtropical and subequatorial. Due to its location, the mainland receives a huge amount of solar radiation every year, and almost the entire territory is dominated by high atmospheric temperatures, so this land is very warm and sunny.

Climatic zones of forests

Forest is a natural zone that is found in many climatic zones of the earth. It is represented by trees and shrubs that grow densely and are located in vast territories. In the forest live such species of fauna that can survive in such conditions. One of the useful functions of this ecosystem is the ability to self-renew.

Climate-forming factors

The climate of the planet is not constant, it changes over time. Sometimes the weather of one season of the current year can be very different from the weather of the previous year. In addition, over dozens, and especially hundreds and thousands of years, the climatic situation has changed significantly. Various factors influence this.

Arid and Humid Climate

In addition to the main climatic zones, in nature there are several transitional and specific, characteristic of some natural zones and a special type of terrain. Among these types, it is worth highlighting the arid, which is inherent in deserts, and the humid, waterlogged climate, located at some points on the planet.

Ozone Depletion

Ozone is a type of oxygen that is located in the stratosphere, approximately at the level of 12-50 kilometers from the earth. The highest concentration of this substance is at a distance of approximately 23 kilometers from the surface. Ozone was discovered in 1873 by the German scientist Schonbein. Subsequently, this oxygen modification was found in the surface and upper layers of the atmosphere.

Temperate climate zone

A temperate climate zone is present on all continents of the earth, except Antarctica. In the southern and northern hemispheres, they have some features. In general, a temperate climate is on 25% of the earth's surface. A distinctive feature of this climate is that it is inherent in all seasons, and four seasons are clearly visible.

Seismic belts

Zones with seismic activity, where earthquakes occur most frequently, are called seismic belts. In such a place, increased mobility of lithospheric plates is observed, which is the reason for the activity of volcanoes. Scientists say that 95% of earthquakes occur in particular seismic zones.

Climatic zones of Africa

In Africa, peculiar climatic conditions. Since the continent crosses the equator, in addition to the equatorial belt, all other climatic zones are repeated. Equatorial belt of Africa The equatorial belt of the African continent is located in the Gulf of Guinea. It has warm air and a humid climate.

Climatic zones of Australia

Features of the geographical location of Australia, relief and oceans have influenced the formation of a unique climate. A huge amount of solar energy and always high temperatures come here. The air masses prevail tropical, which makes the continent relatively dry. On the mainland there are deserts and tropical forests, as well as mountains with snow-capped peaks.

How Russia will fight global warming

Many experts offer various options to combat the problem of global warming. This issue is dedicated to the climate conference in Paris, organized by the UN. It was attended by leaders of many countries, including the president of the Russian Federation. This conference was a major historical event, during which agreements and commitments on improving the climate in each country were developed.

Weather anomalies threaten farmers

Recently, global climate change has become a strong influence on natural phenomena, and accordingly on the agricultural sector. Yields are also negatively affected by floods and droughts. Scientists are developing various climate control methods. The experience of foreign countries In Europe, several years ago, a program was developed and implemented, according to which adaptation to climate change is carried out, with a budget of 20 billion.

How the world has changed lately

The problem of global warming reaches catastrophic proportions. From the height of human growth, this is almost imperceptible, but NASA presented a selection of photographs taken from space heights that make you think. This is a photo of one place with a difference of several years. On some images, places are shown with a difference of 5 years, and in some - 50.

California Climate Belt

California is in North America, lies in the temperate and subtropical zone. The proximity of the Pacific Ocean is of great importance here. Therefore, a Mediterranean type of climate has formed in California. Northern California lies in a temperate marine climate. West winds blow here. It is relatively cool in summer and warm in winter.

Ecological problems of the South China Sea

The South China Sea is located off the coast of Southeast Asia in the Pacific Ocean. Important sea lanes pass through this water area, which is why the sea has become an important geopolitical object. However, some countries should reconsider their policies regarding the South China Sea, because their activities adversely affect the ecosystem of the water area.

What climate zone is missing in North America

North America lies in the western hemisphere of the planet, and from north to south the mainland occupies more than 7 thousand kilometers. The flora and fauna are diverse on the continent due to the fact that it lies in almost all climatic zones. Climate of North America The Arctic climate reigns in the vast Arctic, Canadian archipelago and in Greenland.
