Soil formation processes

In this Class 11 Geography topic from Geomorphic Processes, students learn how soil develops through the weathering of rocks and the gradual interaction of parent material, climate, organisms, relief and time. The topic explains key processes such as the addition and loss of materials, transformation of minerals and the movement of clay and other substances within the soil profile. It also helps students understand soil horizons, profile development and the influence of erosion and drainage on soil formation.

  1. Because weathering biological action material transfer and time work together
  2. Because it depends only on rock colour
  3. Because it completes in one day
  4. Because climate has no role in it
View options
  1. When only salt crystals form on the surface
  2. When clay particles move from upper layer to lower layer
  3. When rock melts without water
  4. When glacier deposits in the sea
View options
  1. Calcification

  3. Illuviation
  4. Glacial erosion
View options
  1. Accumulation of highly acidic leaves
  2. Permanent waterlogging
  3. Intense glacial erosion
  4. Low leaching and accumulation of calcium carbonate
View options
  1. Acidic water carries iron aluminium and organic matter downward
  2. Calcium carbonate accumulates heavily on the surface
  3. Salts rise upward by capillary action

View options
  1. Low temperature and permanent ice
  2. Intense chemical weathering and leaching
  3. Complete waterlogging and oxygen deficiency
  4. Deposition of only sand by wind
View options
  1. Rapid evaporation and salt surface
  2. Dense wind deposition
  3. Waterlogging and reducing condition
  4. Rapid erosion on dry slope
View options
  1. Balanced accumulation of humus
  2. Deep accumulation of calcium carbonate
  3. Increase of organic matter by dense forest
  4. Dispersion of particles by sodium
View options
  1. Because base cations such as calcium and magnesium are leached, and H⁺ and Al³⁺ replace them
  2. Because acidification immediately converts all soil minerals into humus
  3. Because acidification completely destroys the soil cation-exchange sites
  4. Because acidification completely stops water infiltration into the soil
View options
  1. By turning metal ions into insoluble rock
  2. By binding them with organic molecules and keeping them soluble
  3. By depositing all salts on the surface
  4. By immediately ending waterlogging
View options
  1. Because salts always move upward
  2. Because salts become rock
  3. Because water can wash soluble salts downward
  4. Because roots eat all salts
View options
  1. Valley cutting by glacier
  2. Formation of surface salt crystals
  3. Parent rock becoming lava
  4. Development of brown colour due to iron compounds
View options
  1. Development of red colour

  4. Complete transparency
View options
  1. Increase of only pebbles in soil
  2. Mixing of dark organic matter in topsoil
  3. Erosion by sea waves
  4. Complete melting of parent rock
View options
  1. Cold dry and ice covered condition

  4. There has been little time for horizon development
View options
  1. Continuous accumulation of materials from upper layers
  2. Melting of parent rock every year
  3. Direct effect of sea tides
  4. Absence of water in air
View options
  1. Because slope stops rainfall
  2. Because runoff and gravity remove material downslope
  3. Because humus increases immediately
  4. Because parent rock always remains soft
View options
  1. Ocean depth
  2. Name of the year
  3. Differences in drainage accumulation and erosion
  4. Number of solar eclipses
View options
  1. Because all particles are of equal size
  2. Because no deposition occurs
  3. Because vegetation occurs only at the apex
  4. Because coarse and fine particles deposit separately as energy declines
View options
  1. It can block downward movement of roots and water
  2. It doubles all nutrients
  3. It makes humus compulsory
  4. It increases rainfall
View options
  1. Salinization forms horizons and sodication stops time
  2. Salinization relates to soluble salts and sodication to sodium dominance
  3. Salinization occurs only by glacier and sodication only by sea
