Q. What type of soil is found in the river deltas of the eastern coast? Give three main features of this type of soil.

Q. Which of the following are the characteristics of alluvial soil?

1. Very fertile and suited for agriculture.
2. Contains coarser soils compared to mountain soil.
3. Can be sub-categorised based on age and soil fertility.
4. Contains minerals like potash, phosphoric acid and lime.

Q. Which soil develops deep cracks in hot weather, which helps in proper aeration of the soil?

1. Red soil
2. Alluvial soil
3. Regur soil
4. Laterite soil

Q. Which type of soil lacks both moisture and organic material?

1. Black soil
2. Arid soil
3. Alluvial soil
4. Forest soil

Q. Desert soil is rich in:

1. Nitrogen
2. Humus
3. Soluble salts
4. Organic matter

Q. How is red soil formed?

1. Deposition of alluvium and its silicates by winds and seawaves
2. Rainfall on black soil increases the pH value to give red colour
3. Weathering of rocks like granite and gneiss
4. Weathering of basalt rock

Q.

what are the important factors for the formation of alluvial, forest& arid soil?

Q. <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Choose the correct option.

Statement I: Black Soil is formed due to disintegration of volcanic rocks.

Statement II: Alluvial Soil is also called Regur Soil.

1. Both the statements are true.
2. Both the statements are false.
3. Statement I is true, Statement II is false.
4. Statement I is false, Statement II is true.

Q. Describe any three main feature of "Alluvial soil" found in India

Q. Following passage explains process of soil formation of a particular type:

Once the deccan trap region was prone to volcanic eruptions in the past.Over time, the lava from the volcano continued to accumulate and became solid. The solid rocks formed by the lava are called igneous rock.Continuous weathering and erosion of these rocks formed_____soil.

Identify the soil.

1. Red Soil
2. Laterite soil
3. Black soil
4. Alluvial Soil

Q. Mountain soil is rich in lime, but deficient in iron.

1. True
2. False

Q. Which of the following is NOT true with regards to laterite soil?

1. Laterite soil develops under tropical and subtropical climates with alternate wet and dry seasons
2. Heavy rainfall causes leaching of silica and lime, while iron oxide and aluminium compounds are left behind.
3. It is very fertile and supports a wide variety of crops
4. It is deficinet in humus content

Q. <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Which of the following statements is/are true regarding red soil?

1. Red soil is rich in nitrogen, humus and phosphorus.
2. Red soil is used for the cultivation of bajra, pulses, cotton, tobacco, jowar and fruits.
3. Red soil is usually found in areas with high rainfall.
4. Red soil practically encircles the black soil region in the Deccan region.

Q. Read the following statements and select the most appropriate option.

Assertion (A): Regur soil is tilled in pre-monsoon season or immediately after the first rain.
Reason (R): Regur Soil is unfit for the cultivation of cotton.

[0.8 marks]

1. Both A and R are true.
2. A is true but R is false.
3. A is false but R is true.
4. Both A and R are false.

Q. <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Which of the following statements are true about Laterite soil?

1. Laterite soil is generally porous and open in the top layer. It is dense and compact in the lower layers.
2. The soil is poor in iron and aluminium oxides, hence it’s not acidic in nature.
3. Laterite soil is good for cultivating tapioca and cashew nuts.
4. Laterite soil is formed due to the process of Leaching.

Q.
