Arpit Choudhary・2 minutes read

The class covers World Geography, starting with Grass Land and then moving on to Winds, focusing on theory and practical concepts, including major Grass Lands, cloud types, atmospheric layers, and oceanic currents. The topics covered include Tropical and Temperate Grass Lands, different types of clouds, cyclonic rainfall, oceanic currents' impact, and climatic conditions related to various geographical features.

Insights

  • Grasslands are divided into tropical and temperate regions, with major types like Savanna in Africa and Pampas in Argentina, showcasing distinct ecosystems.
  • The atmosphere discussion covers layers like Troposphere and Mesosphere, with a focus on key concepts such as gas proportions and the impact of altitude on temperature fluctuations.

World Geography: Grasslands, Winds, Atmosphere, Monsoons

  • The class will cover World Geography, starting with Grass Land and then moving on to Winds.
  • The Grass Land topic will be divided into two parts, focusing on theory.
  • Tropical Grass Land is located near the equator, while temperate grasslands are found at higher latitudes.
  • Major Grass Lands of the World include Savanna in Africa, Campos in Brazil, and Liano in Venezuela.
  • The temperate grasslands include Pampas in Argentina, Downs Plains in Australia, and Steppes in Russia.
  • The desert topic covers Kalahari in Botswana, Atacama in Chile, and the largest temperate desert in Argentina.
  • The atmosphere section discusses layers like Troposphere, Stratosphere, Mesosphere, and Thermosphere.
  • The atmosphere questions include the sequence of layers, gas proportions, and lowest temperature recorded in the mesosphere.
  • The Summer Monsoon winds blow from the southwest direction in the Northern Hemisphere.
  • The Inter Tropical Convergence Zone is a low-pressure zone located around the equator.

Cloud Types and Orographic Rainfall: A Summary

  • Kamlo Stus are of two types: high cloud, middle cloud, and low cloud.
  • High clouds produce precipitation and include nimbostratus and strato cumulus.
  • High clouds are those where the head appears, like nimbo clouds that make it rain.
  • The types of high clouds are nimbostratus, strato cumulus, and nimbus.
  • The temperature decreases as altitude increases in the troposphere.
  • Clouds are taught in one and a half hours, with a focus on concepts and practice questions.
  • Orographic rainfall occurs due to the expansion of air against mountain barriers.
  • Orographic rainfall is more on windward slopes of mountains than leeward slopes.
  • Mist has more moisture than fog, and precipitation can be liquid or solid.
  • The wind blowing from subtropical high pressure to subpolar low pressure is called westerly.

"Ceres' Serous Ice Crystals and Cyclonic Rainfall"

  • Ice crystals in Ceres form in a serious cloud.
  • Ice crystals in a serious cloud are known as serous ice crystals.
  • Cyclonic rainfall lasts longer than convection rainfall.
  • Cyclonic rainfall occurs for a short duration.
  • Inversion of rainfall is crucial to check for cyclonic rainfall.
  • The thickness of the atmosphere is maximum at the equator due to high insulation.
  • Isotherm represents equal temperature in weather patterns.
  • Isohel indicates equal sunshine in weather patterns.
  • Isohaline signifies equal salinity in weather patterns.
  • The ITC root is formed near the equator.

Glacial Moraine and Oceanic Currents: A Summary

  • Moraine water activity is not underground; aerial activity is not water activity.
  • The land form of a moraine glacier is till and Moren Hey Asla Basla.
  • Glacial till and moraine form the land form of a glacier.
  • The turn is made from the glacier; underground water running water becomes glacier.
  • Moraine indicates a glacier; Canon River to Jagan Wind to Insel Square.
  • The wind is the aerogenital; the wind is formed by the oceanic current.
  • The oceanic current is different from the remaining three; it is in the Atlantic, Pacific, and Indian oceans.
  • Rotation of Earth, air pressure, wind, and density of oceanic water affect oceanic currents.
  • Low air pressure develops over a large area along the coastal region; a warm current is present.
  • The Humboldt Current of Peru and Chile is a cold current on the coast.
  • Spring tide occurs when the Sun, Moon, and Earth are approximately aligned; all three forces contribute to tides.
  • During the day, the wind blows from sea to land; lower pressure develops over land compared to the sea.

Cyclones, Anticyclones, and the Suez Canal

  • The center of a cyclone has low pressure, with high temperature near 10 degrees inside the eye.
  • Anticyclones have high pressure centers, with wind diverging outwards and indicating dry weather conditions.
  • Cyclones in the Northern Hemisphere circulate winds in an anti-clockwise direction, while in the Southern Hemisphere, winds circulate clockwise.
  • Cyclones in the Bay of Bengal move from Bangladesh towards India, affecting states like Andhra Pradesh.
  • The Suez Canal is a man-made navigation canal connecting the Mediterranean Sea to the Red Sea, with economic and strategic significance.
