Soil Types and Water Retention

The video tutorial explains the three main types of soil: sandy, clay, and loamy. Sandy soil is coarse and found on beaches, allowing air and water to pass through but not retaining water well. Clay soil has fine particles, retains water effectively, and is suitable for water-loving plants. Loamy soil, a mix of sand, clay, and humus, is ideal for plant growth due to its balanced water retention. An activity demonstrates the water retention capacity of each soil type, showing clay holds the most water while sandy holds the least.

What are the three types of soil based on particle size?

• Gravel, peat, and chalk

• Rocky, muddy, and silty

• Sandy, clay, and loamy

• Silt, peat, and chalk

Which soil type is known for having large particles that allow air and water to pass through easily?

• Loamy soil

• Sandy soil

• Peaty soil

• Clay soil

Where is sandy soil commonly found?

• Deserts and mountains

• Beaches and riverbanks

• Forests and grasslands

• Urban areas

Which soil type has very fine particles that stick together and can hold a lot of water?

• Sandy soil

• Loamy soil

• Chalky soil

• Clay soil

What type of plants grow well in clay soil?

• Rice

• Cacti

• Orchids

• Pine trees

What is loamy soil a mixture of?

• Silt, peat, and humus

• Chalk, sand, and clay

• Gravel, silt, and peat

• Sand, clay, and humus

Why is loamy soil considered the best for plant growth?

• It is the most colorful soil

• It is found in urban areas

• It retains some water and allows excess to drain

• It is rich in minerals

In the water retention activity, which soil type holds the least amount of water?

• Clay soil

• Loamy soil

• Sandy soil

• Peaty soil

During the experiment, which soil type was observed to hold the maximum amount of water?

• Clay soil

• Chalky soil

• Loamy soil

• Sandy soil
