Ans. Bile is produced in liver. The bile juice stored in sac called the gall bladder. It helps in the digestion of fats.

Q.3:Explain how soil is formed.
Ans. Soil is formed through the process of weathering. Weathering is a process of physical breakdown and chemical decomposition of rocks and minerals near or at the surface of the earth. This physical and chemical decomposition is primarily done by wind, water, and climate. As a result of these processes, large rock pieces are converted into smaller pieces and eventually to soil.

Q.4:Name the elements that determine the weather of a place.
Ans.The elements that determine the weather of a place are temperature, humidity, rainfall, and wind speed.

Q.5 :When are the maximum and minimum temperatures likely to occur during the day?
