Isotherms: UPSC Mind Map

Interactive mind map for Isotherms, covering key concepts, relationships, and facts relevant to UPSC Prelims and Mains preparation.

Key Concepts in this Mind Map

Isotherms
Definition
* Lines connecting points of equal temperature
* Represented on maps and weather charts
* Origin: Greek "iso" (equal) + "therme" (heat)
Characteristics
* Spacing
* Close spacing: rapid temperature change (steep gradient)
* Wide spacing: gradual temperature change (gentle gradient)
* Intersection: Never intersect (except theoretically at a point of infinite gradient)
* Alignment: Generally parallel to latitudes over oceans
* Seasonal Shift
* Shift poleward in summer
* Shift equatorward in winter
Significance & Uses (UPSC Relevance)
* Climatology: Understanding global and regional temperature distribution
* Meteorology: Weather analysis and forecasting
* Air Masses: Identifying boundaries between warm and cold air masses
* Oceanography: Studying thermal structure of oceans, ocean currents
Factors Affecting Distribution
* Latitude
* Temperature generally decreases from equator to poles
* Altitude
* Temperature generally decreases with increasing height
