Explanation

• The stratosphere prevents UV rays from surface of the Earth
  
• 90% of the ozone in the atmosphere is occupied by the Stratosphere.
• Ozone molecules are constantly formed and destroyed in the stratosphere

Additional Information

Ozone is a molecule that contains three oxygen atoms

The atmosphere can be divided into five layers:

1. Troposphere (all weather occurs within this layer)
2. Stratosphere (ozone layer absorbs UV rays)
3. Mesosphere (coldest layer of the atmosphere)
4. Thermosphere (radiowaves transmitted from the Earth and reflected by this layer)
5. Exosphere (molecules and atoms escape)

Explanation

Wind is the moving air in the Earth's atmosphere.

Kinetic energy is the energy possessed by moving particles

therefore wind possesses kinetic energy.

Additional Information:

The horizontal movement of air is known as winds.

Chemical energy is energy stored in the bonds of atoms and molecules

Explanation

Cyclones are usually accompanied by high rainfall.

heavy showers mean: A period of heavy rain

Cyclones mean  ایک قسم کی طوفان

heavy showers  زیادہ بارش/  بھاری بارش

Explanation

Soil pollution is primarily caused by acid rain.

Acid rain contains pollutants like sulfuric and nitric acids, which can degrade soil quality by altering its pH and harming plant life.

Explanation

The ozone layer protects living things from too much ultraviolet  from entering the atomsphere

Oxygen layer in the atmosphere

Ozone protects us from the harmful ultraviolet radiation of the sun.

Ozone formula: O3

The ozone layer lies approximately 15-40 kilometers (10-25 miles) above the Earth's surface, in the stratosphere.

The ozone layer is depleting: Air pollution

Explanation

A monsoon is caused by a seasonal shift in the winds.

The winds shift because the temperature of the land and the temperature of the water are different as seasons change. 

monsoon season duration is April and September.

Explanation

Lead is the metal that pollutes the air of big cities.

Due to the usage of lead petroleum,

when a lead is emitted, it causes damage to air and is a major pollutant.

Explanation

The troposphere is the lowest layer of Earth's atmosphere.

Most of the mass of the atmosphere is in the troposphere.

Most types of clouds are found in the troposphere, and almost all weather occurs within this layer.

Major layers are 

troposphere

stratosphere

mesosphere

thermosphere 

exosphere

Explanation

Radio waves are  Electromagnatic waves

  with the longest wavelengths in the electromagnetic spectrum, typically with frequencies of 300 gigahertz 

Radio waves were first predicted by the theory of electromagnetism proposed in 1867 by Scottish mathematical physicist James Clerk Maxwell

Explanation

The central color of a rainbow is Green

ROYGBIV: This mnemonic helps remember the order of colors. 

1. Red (outermost)
2. Orange
3. Yellow
4. Green (central) 
5. Blue
6. Indigo
7. Violet (innermost)
