Question2).Greenhouse effect is a term used to explain how a planet’s surfacegets warmed up through radiation from its atmosphere resulting inincrease in temperatures more than what ought to have been in theabsence of greenhouse gases in the atmosphere. The greenhouse effectcomes about due to presence of some gases in the atmosphere that forma blanket cover above the earth’s surface known as the greenhousegases. The main greenhouse gases that bring about the greenhouseeffect are carbon dioxide and methane. These gases consequentlyresult in a variety of adverse effects like global warming.

Question6).Isotherms are lines commonly used to connect points of equaltemperature and are often used to map geographic temperature patternsacross the earth’s surface. Distribution of large land masses andwater bodies largely influence the shape of the isotherms. Thedifferential heating of water and land mass makes the isotherm shiftfrom a cooler to a warmer region.

Inthis diagram, the isotherm shifts towards the equator as shown inwinter as the land mass temperature changes faster than that ofwater and hence don’t follow the straight latitude due to thechanges in temperature upon reaching the landmass in addition to theeffect of seasons as they bend towards the equator in winter and tothe poles in summer on the landmass
