The laws of nature, the earth s air changes 40

The law of the Earth's rotation is from east to west. Counterclockwise over the North Pole and clockwise over the South Pole. The rotation of the earth will cause the phenomenon of day and night, which will cause various motion rotation phenomena, and the earth will produce different latitudes and longitudes, and the time will vary by an hour every 15 degrees of longitude.

The law of the Earth's rotation is that the linear speed of the Earth's rotation decreases from the equator to the poles, and the Earth's rotation is one day.

The natural phenomena that do not occur when the earth's rotation is as follows: day and night, the hemisphere facing the sun is day, and the hemisphere facing the sun is night; time difference between the East and West regions; Where there are different places at different degrees of longitude, the longitude varies by one hour every 15 degrees.

The rotation of the earth is from west to east. The natural phenomenon is the alternation of day and night, and there is also a time difference, and there is also a geostrophic deflection.

It mainly introduces global warming, its effects and causes; Measures to combat global warming.

The Earth and the atmosphere will also change constantly, and the distance between the Earth and the atmosphere will be shortened a lot, and the distance between the two will be reduced.

Global warming, now due to various pollution caused by human development on the earth, its climate is rising year by year, causing global warming.

If the Earth ceases to rotate, then the Earth's atmospheric circulation will change. It is difficult for the Earth's atmosphere to move from one place to another, resulting in humid places with more rainfall and more arid places where they are dry.

Soil is destroyed. Currently, arable land in 110 countries is decreasing in fertility. In Africa, Asia and Latin America, soil erosion is severe due to the loss of forest cover, overexploitation of cultivated land and overgrazing of pastures.

Air pollution. The problem of air pollution is also the problem of acid rain. Previously, the problem of acid rain had only concerned the older industrialized countries of Europe and North America.

But now, parts of Asia and Latin America, where the economy is booming, are also being hit by acid rain. Air pollution also disrupts the functioning of ecosystems, accelerates the damage to homes, and leads to climate variability.

Fresh water is threatened.

In developing countries, 80% of 90% of diseases and more than 1 3 deaths are related to bacterial infections or chemically contaminated water. Today, 10,000 men, women and children die every day from water-borne diseases.

climate change and energy waste.

The greenhouse effect is a serious threat to humanity as a whole. According to a representative group of 2,500 experts, sea levels will rise, and rising temperatures will have serious impacts on agriculture and ecosystems.

Reduced forest area.

Over the past few hundred years, temperate countries have lost most of their forests. In recent decades, the decline in forest area in tropical countries has also been severe. At the current rate of forest loss, in 40 years' time, forests will be inaccessible in some Southeast Asian countries.

Reduction in biological variety.

Due to urbanization, agricultural development, deforestation and environmental pollution, the natural areas where organisms exist are becoming smaller and smaller, which has led to the extinction of thousands of species.

Chemical contamination. Millions of compounds from industry are found in the air, soil, water, plants, animals, and the human body. Even the ice caps, which are the last large natural ecosystems on Earth, are polluted.

Chaotic urbanization.

The deterioration of the population and the deterioration of agricultural land and poverty have prompted millions of peasants in the Third World to leave the countryside and gather in the slums of the big cities. With the advent of the new century, living conditions in some large cities will deteriorate further.

Overexploitation of the oceans and pollution of coastal strips.

As a result of overfishing, the ocean's fishery resources are dwindling at a frightening rate. As a result, many poor people who depend on seafood protein for their livelihoods are at risk of hunger.

Polar Ozone Hole Every spring, an ozone layer hole forms over the Earth's two polar regions, with a loss of 20 30 ozone layer in the Arctic and more than 50 in the Antarctic.

The change of the movement of the atmosphere is caused by the exchange of heat energy in the atmosphere, which is mainly due to the sun, and the exchange of heat energy makes the temperature of the atmosphere rise and fall. The movement of air and the change of the air pressure system make the energy and matter exchange between the sea and land, between the north and the south, and between the ground and the high altitude on the earth, resulting in complex meteorological changes and climate change. Atmospheric science will deeply study various circulation systems and weather systems in the atmosphere, as well as the nature and phenomena of atmospheric motion based on fluid mechanics and thermodynamics, from the changes in air pressure, the pressure field and pressure system formed by uneven distribution of air pressure, the various conditions of air movement in various layers of the atmosphere, and the phenomenon and nature of wind.

Weather, phenomenatically, is largely the result of changes in moisture in the atmosphere. Under the combined action of solar radiation, underlying surface forcing and atmospheric circulation, the long-term composite of the weather formed is called climate. Atmospheric science will study the causes of climate, the climate conditions in different regions, climate change, and the impact of human activities on the climate.

c The reason for the change in the length of day and night is that the Earth's axis is tilted and points to the vicinity of Polaris.

Due to the rotation of the earth, there is a change of seasons; The rotation of the earth produces a diurnal cycle; The formation of the polar day and the polar night is caused by the rotation of the earth around its own inclined axis as it orbits the sun in an elliptical orbit. Therefore, C is selected for this question.
