1. How are oceans important in the water cycle?
Ans: The importance of the oceans in the water cycle is as follows: The oceans have the world's largest supply of freshwater. Oceans have the maximum surface area exposed to the sun for evaporation. As a result, the oceans give the majority of the water that changes to water vapour in the atmosphere. Clouds form when the water vapour condenses. Clouds collect and condense water, becoming large droplets that descend to Earth as rain, snow, or hail. Oceans are therefore necessary for the formation of sufficient water vapour, which helps in the water cycle.
2. How is groundwater affected by concrete flooring?
Ans: Concrete is a porous material with no pores. It stops water from passing through. As a result, when rain falls on concrete floors, it cannot pass through. This stops the rainwater from replenishing groundwater. Because rainwater seepage to groundwater is obstructed, groundwater cannot be recharged, and the water table suffers.

Water is one of the most fundamental needs of the human body. Every human needs water to perform simple functions of the body. These include mainly digestion and absorption.
Water is the main ingredient the human body uses to create sweat during perspiration to cool the entire body down. Water is also utilised to create digestive juices and waste (intoxicant) materials such as urine.
It is key to know that water keeps the human body hydrated, in turn regulating its temperature and preventing extreme body temperatures.
2. What’s the definition of evaporation?
Evaporation refers to the process of a liquid substance turning into gas. The process is well-known among students when they are taught about the water cycle.
Evaporation takes place when an amount of water is exposed to heat, causing the water particles to move at a rapid pace. This further constitutes the particles at the surface to escape and turn into vapour. Soon enough the entire amount of water can also be converted into vapour if exposed for longer durations.
3. What is the process to harvest rainwater?
Rainwater can be harvested by any means.
The simplest and widely used method is to store it into a big storage item.
Usually, societies use a big area to construct a storage device which is placed in the area where the majority of the rain can be collected i.e. in open fields with no barriers.
These storage spaces are further installed with pipes to utilize the collected rainwater.
Harvesting rainwater is a common practice worldwide and can be done with ease.
4. What is a water cycle?
The water cycle is one of the most well-known phenomena students are taught.
The water cycle is also known as the Hydrological or Hydrologic cycle. It refers to the movement of all water bodies on, below and above the Earth. These movements include ice glaciers, oceans, sea bodies and lakes.
The water cycle defines the movement of water from one place to another such as ocean water moving into the clouds through evaporation, river water moving to oceans, etc. It also shows the different state's water turns to during these processes.
