Depth refers to the distance from the top or surface of something to its bottom or innermost part. In the context of science, depth is often used to describe the distance below the surface of water, soil, or any other substance.
Factors Affecting Depth
Density: The denser a substance, the greater the depth it can support. For example, a denser liquid can support greater depth compared to a less dense liquid.
Pressure: The depth of a substance is also influenced by the pressure exerted on it. Deeper depths experience higher pressure, which can affect the properties of the substance at that depth.
Develop and use models of Earth’s interior composition to illustrate the resulting magnetic field (e.g., magnetic poles) and to explain its measureable effects (e.g., protection from cosmic radiation).
