4.Green House Effect refers to
a. Warming of Earth.
b. Cooling of Earth.

Answer: a. Warming of Earth.
Explanation: The green house effect
is a natural process. When the energy of sun reaches to the Earth atmosphere in
the form of Light. Some of this energy is reflected back to the space and rest
of the part of this energy is absorbed by greenhouse gases which is presence in
the earth atmosphere and is re-radiated and this trapped heat keeps Earth
Warms.

temperature of the earth would be around -18°C while in the presence of GHGS
average temperature is 15°C.

Answer: d. All of the above.
Explanation: Global warming is the long-term heating of earth surface observed since the preindustrial period (between 1850 to 1900) due to human activities, primarily fossil fuel burning. Which increases heat trapping greenhouse gas levels in the earth atmosphere. More frequent and intense drought, storms, heat waves, rising sea levels, melting Glaciers and warming Oceans can directly harm the animals, destroy the places they live and wreak havoc on people’s livelihoods and communities.
