2) It sustains life on the Earth by not allowing Earth to become too hot or too cold


Which of the above statements is/are correct?

2. Which of the following soils found in India are poor in nitrogen, phosphorous and humus?



  1. Red and Yellow Soil

  2. Black Soil

  3. Laterite Soil

3. Consider the following statements about soil erosion:



  1. Sheet erosion takes place on level lands after a heavy shower and the soil removal is not easily noticeable

  2. Gully erosion is common on steep slopes. Gullies deepen with rainfall, cut the agricultural lands into small fragments and make them unfit for cultivation


Which of the above statements is/are correct?

4. Consider the statements regarding this weather layer:


1) The height of the troposphere increases from Equator to the Poles.


2) The height of the troposphere is comparatively more during the summer season than in the winter season


Which of the above statements is/are correct?

5. Consider the statements regarding insolation which is nothing but the radiant energy received from the Sun in the form of heat and light:


1) Insolation received on the surface of the Earth decreases from Equator to the Poles


2) During Summer Solstice, maximum insolation received at the ground surface is between the 30 to 40 degree South latitudes


3) Insolation received is comparatively higher in the outer limit of the atmosphere than that is on the surface of the Earth


Which of the above statements is/are correct?

6. Which of the following methods are best suitable to prevent gully erosion?



  1. Finger gullies can be eliminated by terracing

  2. In bigger gullies, the erosive velocity of water may be reduced by constructing a series of check dams

  3. Head ward extension of gullies can be controlled planting cover vegetation

7. Which of the following statements regarding Soil Health Card Scheme are correct?



  1. It will contain the status of his soil with respect to Macro-nutrients, Secondary nutrient, Micro - nutrients and Physical parameters

8. Which of the following methods can be useful in soil conservation?



  1. Use of Early Maturing Varieties of crops.

  2. Contour Ploughing

  3. Strip cropping

9. Which of the following statements is/are correct regarding the process of Crop rotation?



  1. It is the process of growing different crops in a field simultaneously

  2. It helps in natural pest control

  3. It prevents depletion of a particular nutrient from soil and helps in maintaining soil fertility for a longer time

10. Temperature anomaly is the deviation of temperature either more or less than the average of the surrounding region:


1) Positive anomaly is the record of higher temperature than the normal which is identified over the land in lower latitudes during day time


2) Negative nomally is the record of lower temperature than the normal which is identified over the sea in higher latitudes during night time


Which of the above statements is/are correct?
