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

CFCs, carbon dioxide (CO₂), and methane (CH₄) are all greenhouse gases.

They trap heat in the atmosphere, leading to global warming.

Explanation

The ultraviolet rays are filtered through Ozone Layer.

The ozone layer, often known as ozone shield is a part of Stratosphere.

Explanation

• The stratosphere is the layer of the atmosphere where the ozone layer is present.
• It extends from approximately 12 to 50 kilometers (7.5 to 31 miles) above the Earth's surface.
• The ozone layer is a critical component of the Earth's atmosphere, as it absorbs harmful ultraviolet (UV) radiation from the sun, protecting life on Earth.

Explanation

A point source of pollution is a single, identifiable source from which pollutants are discharged, such as a factory or industry.

Industries release waste directly into air or water from specific locations.

Explanation

Acid rain is called an "unseen plague" because its harmful effects on soil, water, and structures occur gradually and often go unnoticed at first.

It can silently damage ecosystems, corrode buildings, and acidify water bodies over years without immediate visible signs.

Explanation

Lithosere succession takes place on bare rocks. 

 "Litho" refers to "rock,"

So lithosere specifically describes the process of ecological succession that begins on exposed rock surfaces

Explanation

• The ozone layer in the stratosphere absorbs and restricts ultraviolet (UV) radiation from the sun.
• It protecting life on Earth from harmful UV rays.

Explanation

The approximate surface temperature of the Sun, also known as the photosphere,

It is around 5,800 Kelvin (5,500 degrees Celsius or 10,000 degrees Fahrenheit).

Explanation

The approximate height of Earth's atmosphere is 6,200 miles (10,000 kilometers).

This is the approximate extent of the exosphere, the outermost layer of the atmosphere, which gradually merges with space.
