Here are detailed notes on Rocks, Rock Cycle, and Soil for a Grade 6

Cambridge student:

*Rocks*

1. *Definition*: Rocks are naturally occurring solid masses of mineral


material.

2. *Types*:

- *Igneous rocks*: Formed from molten magma or lava.

- *Sedimentary rocks*: Formed from compressed sediments.

- *Metamorphic rocks*: Formed from transformed rocks under heat and


pressure.

*Rock Cycle*

1. *Definition*: The rock cycle is the continuous process of rock formation,


transformation, and destruction.

2. *Processes*:

- *Igneous rock formation*: Magma cools and solidifies.

- *Weathering and erosion*: Rocks are broken down into sediments.

- *Sedimentary rock formation*: Sediments are compressed and


cemented.

- *Metamorphism*: Rocks are transformed under heat and pressure.

- *Melting*: Rocks melt to form magma.

*Soil*

1. *Definition*: Soil is a mixture of mineral particles, organic matter,


water, and air.

2. *Formation*: Soil forms through the weathering of rocks and the


decomposition of organic matter.

3. *Importance*: Soil supports plant growth, filters water, and stores


carbon.

*Soil Composition*
1. *Mineral particles*: Sand, silt, and clay.

2. *Organic matter*: Decaying plant and animal remains.

3. *Water and air*: Essential for soil health and plant growth.

*Importance of Rocks and Soil*

1. *Supporting life*: Rocks and soil provide essential resources for plants
and animals.

2. *Shaping landscapes*: Rocks and soil influence the formation of


landscapes.

*Key Concepts*

1. *Weathering*: The breakdown of rocks into sediments.

2. *Erosion*: The transportation of sediments.

3. *Deposition*: The settling of sediments.

These notes cover the basics of rocks, the rock cycle, and soil for a Grade
6 Cambridge student.
