D. Greenhouse gas emissions
Answer: Option B
Solution (By JKSSB Mock Tests)
The 'Medieval Warm Period' (roughly 950-1250) was a period of relatively warm conditions in the North Atlantic region, likely due to increased solar activity and reduced volcanic activity.
Explanation:
A temperature inversion is a reversal of the normal temperature gradient in the troposphere, where temperature increases with altitude instead of decreasing. This traps pollutants and can cause fog and smog.
Explanation:
A marine climate (maritime climate) is characterized by a small annual temperature range due to the moderating influence of oceans. Winters are mild, and summers are cool compared to continental climates.
Explanation:
The southeastern United States is influenced by tropical maritime air masses from the Gulf of Mexico and Atlantic Ocean in summer, bringing warm, humid, and unstable weather with thunderstorms.
