Kharif season starts from ?
  • July- October
  • May – October
  • None of the above
Explanation:

The Kharif season in India typically starts with the onset of the southwest monsoon in June and lasts until October, when the harvesting of these crops begins.

Which of the following soil is used for making of pots, statues ?
  • Sandy Soil
  • Clayey Soil
  • Sandy Loam Soil
  • None of the above
Explanation:

Clayey soil is used for making pots, statues, and other earthenware due to its fine particles, high plasticity, and ability to retain shape when molded.

Percolation rate of water is lesser in ?
  • Sandy Soil
  • Clayey Soil
  • Loam Soil
  • None of the above
Explanation:

Clayey soil has a low percolation rate because of its fine particles, which tightly pack together, slowing water movement through the soil.

Percolation rate of water is higher in ?
  • Sandy Soil
  • Clayey Soil
  • Loam Soil
  • None of the above
Explanation:

Sandy soil has a higher percolation rate due to its large particles, which allow water to flow through more quickly compared to clayey or loamy soils.

Formation of soil by breaking down of __________ ?
  • Rocks
  • Iron rust
  • Both a and b
  • None of the above
Explanation:

Soil formation occurs through the breakdown of rocks into smaller particles by weathering processes, including physical, chemical, and biological actions.

Dead material or matter present in soil is called as
  • Waste soil
  • Dirty Soil
  • Humus
  • All the above
Explanation:

Humus is the organic component of soil, formed by the decomposition of leaves, dead plants, and other organic material, which enriches the soil.

Hot or Warm Air always
  • Rises up
  • Shrink Down
    • Explanation:

    Warm air rises due to lower density, while cooler air sinks, creating convection currents. This process influences weather patterns, forming clouds and causing wind, crucial for Earth's climate dynamics.
