Explanation

• The sun generates electricity from a manner known as nuclear fusion. at some point of nuclear fusion, the high stress and temperature in the solar's middle cause nuclei to split from their electrons. Hydrogen nuclei fuse to shape one helium atom.
• sun power is electricity that comes from the solar. every day the solar radiates, or sends out, an vast amount of electricity. The sun radiates extra electricity in a single 2nd than human beings have used on the grounds that the start of time!
• It comes from in the sun itself. Like different stars, the solar is a huge gas ball made up by and large of hydrogen and helium. The solar generates energy in its middle in a system called nuclear fusion. at some point of nuclear fusion, the solar's extraordinarily high strain and extreme temperature reason hydrogen atoms to return apart and their nuclei (the principal cores of the atoms) to fuse or combine. 4 hydrogen nuclei fuse to become one helium atom. however the helium atom weighs less than the four nuclei that blended to shape it. some depend is lost at some point of nuclear fusion. The misplaced remember is emitted into area as radiant power.
  

Explanation

Mangroves grow in salty coastal areas and have roots that stabilize the shoreline, reducing erosion.

They also serve as nurseries for marine life, providing shelter and breeding grounds for fish and other organisms.

Explanation

بنیادی طور پر شہری اور صنعتی علاقوں میں ہوائی آلودگی زیادہ ہوتی ہے کیونکہ ان علاقوں میں گاڑیوں، فیکٹریوں اور دیگر صنعتی سرگرمیوں سے زہریلے گیسوں کا اخراج ہوتا ہے۔

یہ آلودگی فضا میں موجود ہوتی ہے اور انسانوں اور ماحول کے لیے نقصان دہ ثابت ہو سکتی ہے۔

Explanation

Explanation

Sustainable development means meeting the needs of the present without compromising the ability of future generations to meet their own needs.

This definition is from the World Commission on Environment and Development (Brundtland Report).

Explanation

Nitrogen (N2) is the most abundant gas in the Earth's atmosphere

They make up about 78% of the atmosphere's composition.

Oxygen (O2) is the second most abundant gas

Explanation

A point source of pollution refers to a fixed or stationary location, like a factory chimney or wastewater outlet.

It contrasts with mobile sources (like vehicles) or diffuse sources (like agricultural runoff).

Explanation

Suspended particulate matter (SPM) SPM

It is one of the essential particulate contaminants that transport heavy metals in the river system.

Additionally, it is one of the phases of heavy metals in aquatic ecosystems

Explanation

• In space exploration, a spectroscope is typically used to analyze the light coming from stars, planets, and other celestial objects to determine their chemical composition.
• This helps scientists understand the formation and evolution of stars, planets, and galaxies.

Explanation

The stratosphere is rich in Ozone.

The rest of the layers might have ozone to a small extent but not to large extent.
