Answer:
The sand particles have many interconnected pores between them. As a result of which they have some porosity. When water is added to the sand, then the water gets percolate into those tiny voids between the sand grains. Once these spaces are fully filled up with water then it becomes saturated. This means that the sand particles have no more capacity to hold water in its spaces.
This effect can be seen very commonly in the beaches, where the sands are fully saturated, and as someone steps over it, the water starts to come out through this pore spaces. This water that comes out of these footprints is the water that is stored in those tiny pore spaces in a fully saturated condition.

Human activities commonly affect the distribution, quantity, and chemical quality of water resources. The range in human activities that affect the interaction of ground water and surface water is broad. The following discussion does not provide an exhaustive survey of all human effects but emphasizes those that are relatively widespread. To provide an indication of the extent to which humans affect the water resources of virtually all landscapes, some of the most relevant structures and features related to human activities are superimposed on various parts of the conceptual landscape
Answer:
Option (B)
Explanation:
Alto-Cumulus is the type of middle atmospheric clouds that generally appear to be puffy and often look like floating cotton pieces. These clouds usually have a flat base and range from 2000 to 6000 meters above the ground surface. The apex of these clouds has rounded. They are commonly found between the warm front and cold front within a depression. They are mostly hidden by the clouds that are at a comparatively lower height. These clouds do not undergo precipitation.
Hence, the correct answer is option (B).
