Final answer:
The term for Zones B and D in geography are the unsaturated zone and the perched zone, respectively.
Explanation:
The term for Zones B and D in geography is as follows:
Zone B is known as the unsaturated zone, also called the vadose zone or the zone of aeration. This zone is located above the water table and contains both air and water in the soil or rock. It is called the unsaturated zone because the spaces between the soil particles or rock are not completely filled with water.
Zone D is known as the perched zone. It is a localized zone of saturation that occurs above the main water table. The perched zone is typically formed by an impermeable layer of rock or soil that prevents water from infiltrating further down. As a result, water accumulates above this layer, creating a separate zone of saturation.
