Bedrock
The solid layer of rock beneath the soil
Real World Example
Imagine you are trying to find a stable Wi-Fi signal in your home, but you keep getting interrupted by obstacles like walls and furniture. This situation is similar to the way bedrock acts as a stable foundation beneath the shifting layers of soil and debris on the Earth's surface. Just as the stable Wi-Fi signal is the underlying constant you need for a smooth internet connection, bedrock provides the solid, unchanging support necessary for the layers above it to remain steady and secure, despite the shifts and changes they undergo.
