What’s a rock cycle
It’s how the rock is formed, disintegrated, band formed again
What are the 4 concentric layers of the Mantle
- Crust
- Mantle
- Outer core (semi solid)
- Inner core (solid and extremely hot)
What does the lithosphere consist of?
The crust and upper mantle
What’s the inner core
It’s the innermost solid part of the earth. It’s situated at the centre
What’s the outer core
It’s the liquid part that surrounds the inner core
What’s the mantle
It’s a layer above the core of the earth
What’s the crust
The layer surrounding the mantle
What’s a sedimentary rock
It’s former when small stones that have been washed away and deposited as sedim
What does soil consist of
- A mixture of weathered rocks and minerals
- Organic substances derived from decayed plant material and animal waste
