Out of the given options, ‘Without greenhouse gases, Earth would be too cold for life to exist’ explains why greenhouse gases are needed for the survival of life on Earth.

Answer: Option B

<u>Explanation: </u>

Greenhouse gases which includes carbon-dioxide, nitrous oxide, vapours, ozone and methane forms a layer around the earth that prevents the escape of heat energy from earth’s atmosphere. This phenomenon is called Greenhouse effect.

Without the layer of these gases around the planet, everything will be covered with ice on the surface and it would be too cold for the sustenance of any life form on the earth.  Our planet needs a perfect balance of these gases as any excess or too little gases will be deterrent to the life form on earth.

What do you think happened to make the moon look the way it does
ikadub [295]

Answer:

We only see the Moon because sunlight reflects back to us from its surface. During the course of a month, the Moon circles once around the Earth. If we could magically look down on our solar system, we would see that the half of the Moon facing the Sun is always lit. But the lit side does not always face the Earth!

Mengapakah jisim udara tidak diukur dengan neraca tuas<br>​
ra1l [238]

Answer:

Ia tidak mempunyai badan fizikal.

Penjelasan:

Jisim udara tidak diukur oleh keseimbangan tuas atau keseimbangan berat yang lain kerana mustahil untuk mengukur jisim udara. Hanya dua sifat udara yang dapat diukur seperti kadar aliran dan tekanan. Imbangan tuas mengukur berat bahan-bahan yang mempunyai badan fizikal sehingga sebab itu jisim udara tidak dapat diukur kerana tidak mempunyai badan fizikal. Udara mempunyai jisim tetapi tidak mempunyai badan fizikal sehingga mustahil untuk mengukur beratnya.
