Troposphere: It lies from the earth surface to 10 km in the atmosphere. All weather phenomenon happens in this layer. it is also called nature's lab.

Stratosphere: It is the 2nd layer which lies from 10 to 50 km in the atmosphere. It is a calm layer. Aeroplanes fly in this layer due to no weather disturbances.

Mesosphere: It is the 3rd layer and it is the coldest layer of the atmosphere because of ionization process happens in this layer. It lies from 50 to 90 km in the atmosphere.

Thermosphere: It is the 4th layer and it is the hottest layer of the atmosphere because of the presence of meteorites. It lies from 90 to 120 km in the atmosphere.

Exosphere: Its is the 5th layer and here atmospheric structure ends from 120 km. The exosphere is the most distant atmospheric region from Earth's surface.

Answer:

Nuclear weapons are weapons of mass destruction. That's why many countries and international organizations are trying to limit its testing: when a nuclear weapon explodes, a lot of energy is released in the form of heat, pressure wave and ionizing radiation. As a result, a nuclear weapon can quickly destroy an entire city and kill hundreds of thousands of people. The radiation causes acute radiation sickness and long-term damage to health.

Because of the enormous destructive power of nuclear bombs, efforts have always been made to abolish all nuclear weapons and to generally ban them in order to prevent them from being destroyed. The Cold War and the power interests of individual nations, however, prevented a rapid abandonment of weapons of mass destruction. Nevertheless, some agreements were implemented, each of which signaled a major step towards a world free of nuclear weapons. However, it is doubted whether the agreements are actually as effective as desired.
