Explanation

The stratospheric ozone layer is Earth's “sunscreen”  protecting living things from too much ultraviolet radiation from the sun.

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

The ozone layer is a thin part of the Earth's atmosphere that absorbs almost all of the sun's harmful ultraviolet light.

Ozone is made of O3.

Explanation

Destructive waves, known as tsunamis

Caused by underwater earthquakes.

When an earthquake occurs beneath the ocean floor,

it can displace a large volume of water

Generating powerful waves that can travel across the ocean

And cause devastation when they reach coastal areas

Explanation

“shooting stars” are called meteors

Most meteors burn up in the atmosphere before they reach the ground

Shooting stars are little rocks from space that catch fire as soon as they enter the Earth's atmosphere.

Explanation

• Air pollution is actually considered the most dangerous type of pollution.
• According to the World Health Organization (WHO), air pollution is responsible for an estimated 7 million premature deaths worldwide each year, mainly due to heart disease, stroke, and lung cancer.

Explanation

• Deserts are areas with very low rainfall, typically less than 25 centimeters (10 inches) per year.
• It resulting in a barren and often sandy landscape with limited vegetation and wildlife.

Explanation

Cumulonimbus is a dense, towering vertical cloud, typically forming from water vapor condensing in the lower troposphere.

Explanation

·         The path of traffic noise can be locked by constructing vertical barriers along the highways.

·         Proper highway planning and design are essential for controlling traffic noise.

·         Establishing lower speed limits for highways also reduced the noise.

Explanation

Radiant energy is the energy of electromagnetic waves. It is a form of energy that can travel through space. 

For example, we receive the heat from the sun, which is located very far from the earth via radiation. The sun's heat is not transmitted through any solid medium, but through a vacuum. They are short waves.

Explanation

Tundra is a region with a very cold climate, found in the Arctic and Antarctic regions, characterized by:

• Low temperatures
• Short growing season
• Limited vegetation (mainly low-growing shrubs, grasses, and mosses)
• Permafrost (frozen soil)
